Update! I've had a lot of really dumb comments and arrogant "you should do this" comments. I chose the way I did it because the plate had a warp to it. It would not sit flat on the table.

Josh, do not let the Keyboard Mechanics grind you down...... your techniques are always interesting and informative.... many ways to "get the job done right the first time"...... I appreciate your candor and the way you share information with the rest of us......Thank You so Much......PB
The plate looks like it could just be flipped and used. However, I see your comment that it was warped so you fixed it the best way possible. Thanks for posting.
That is awesome seeing that machine being brought back to life. I used to run a 26' by 10' GRAY planer mill at my last job. Looked just like this only larger. Very good machines and they do an excellent job. I like your setup, works well
My dad's shop was similar to yours. All manual equipment, yours in much better shape. Worked many hours in his shop when he needed help. He had a big vertical bed mill with four-foot stroke we would use to slab and cut slots on as well as drill and tap holes with similar chunks of steel. Thanks for sharing, Ken
Thank you for the comment reply. And you answered the question. I actually meant to ask was I bet the people around you are very thankful that you’re there. Sometimes the lack of skilled people is appalling and really makes things difficult, or at least more difficult than they were when I was a young man. Keep up the great videos and I loved the video on how you make your videos.
The gantry design of the planner mill will only have the rigidity with the cutting forces feeding into/against the bridge/gantry style construction, hence planner/shapers only cut in this direction. Another great video and loving your channel 👏 keep the great work going and hope you have a successful new year,love from the UK 🇬🇧 Birmingham, England 🏴
I've picked up a couple of things from CME - and honestly I have had really good results. Angle plate was properly flat and perp, a rotary table was very smooth and accurate (couple of examples) - frankly very impressive for the price.
I have a few items from CME, and most are pretty good. Unfortunately, last time I ordered 6 of #1 and 6 of #2 center drills, and not a single one was usable - the tips were either unevenly ground, had no relief or both.
That was a nice quick and simple video. It didn't look bad to video or edit, either. When I pulled a dump wagon, one of our specialties was hauling sludge from water treatment plants. I've hauled from a couple of digesters and burners that were being overhauled, but mostly from ones that just pull and treat the solids for disposal in a landfill. It's interesting that sludge from Salem, Ma went to landfills near the finger lakes in NY, and sludge from long island went to one near Rochester, NY. Permitting and contracts are interesting. An odd one in Brunswick, Maine... they have a digester, but it's not near a treatment plant so we would haul it 2 hours from Lowell, Ma and simply dump into their bin/conveyor and then they would do their magic.
Very nice results. Only thing I would add is do work on the other side of the bed too, ensuring equal wear so you don't gouge a valley into those ways (the bane of many older machines).
I think a tour of that power company would be a neat video. I bought a plate like that recently. I learned that it was, as you said, a exchanger end plate. Mines a bit bigger 2.75” thick and weighs 2,000lbs. It’s gonna make the best table top 😁
Ah Josh, so many armchair heroes who always know better than the guy in the moment. Forget the naysayers, their comments are worth nothing. I get much enjoyment watching what you do and appreciate your explanation as to why you approach a job in a certain way. I spent 30+ years in the toolmaking trade and one of the earliest things I learned was that there is always more than one way to do a job and achieve the desired result. Keep 'em comin' man. Respect from Downunder.
I honestly believe the know-it-alls have never actually had to do a job like any that I take on. My shop is becoming known for doing the impossible jobs. Most jobs I get have been to a couple other places that say it can't be done. There are also shops that just refer everything to me. I must be doing something right.
I really like that antique planer table having been slightly modified for using that Bridgeport head. I've watched Keith Rucker restore his, but his is belt driven off a line shaft driven by an electric motor. It still maintains the single point shaper head design as you may likely know. What a nice machine you created.
Thanks, but I didn't create it. I bought it this way, just reworked what they had to function far better. I wish it were still a planer, but this has been far more useful than a plain planer would be.
Josh, Have been dealing with CME for a cpl years now, good selection of quality stuff of abt anything u need and prompt service too. My sister in Michigan lives abt 15 minutes away fm them so never any problem in getting stuff picked up or shipped if its bigger size. She just brings it with them when they visit back home here. Have you ever tried a large size fly cutter for the finishing passes, I made a 6 inch diam one that adapts a 1/4 in indexable carbide mini lathe turning cutter.....gives amazing results... Just a minor dusting of snow here now, ground is saturated and softer than hell, couldnt plow if i had to without tearing up everything....def saving on fuel and heating costs so far in the shop, and not freezing my bippy off as usual..... Don
I have 2 big fly cutters for the HBM, that do amazing mirror finishes. The BP Head just isn't ridged enough to handle something that big. I was really pushing it with this head also. We have been really wet, thank god it was rain and not snow. We would be buried like we were last year. Still happy with my snowblower purchase, been blowing that snow out of the region. LOL.
I run my big fly cutter on my 3hp Alliant 10x54 mill.....for small jobs use a reg fly cutter and then if the piece fits, run over it w my surface grinder and a 3M Scotch brite EXL xtra fine wheel I had them custom make to fit my grinder spindle.....@@TopperMachineLLC
I am looking at upgrading vertical mills in 2024. 1HP BP just can't cut it sometimes. The planer is mostly for positioned drilling/milling work, and small long parts. This was a bit excessive for the machine, but I already had a big job in the Boring Mill.
Josh if you’re looking to offload that 1 HP Bridgeport let me know. I’ll gladly come get it. Hassle free sale if you need it. I’m looking to acquire a knee mill this year.
Very cool 😎 a close friend had a similar setup a old planer with a Bridgeport head used for rebuilding mainly Bridgeport mills he would get most stuff within a half thousand and scrape from there
Great machine work , surface looks a little rough but I've had enough stuff planed and I know even with that look that it will be just fine . Looks can be deceiving and the plate is proof of that statement . Great video .
There's a digester setup at the paper mill I worked at. Generated enough biogas to save about three weeks of natural gas. They added a turbine to generate electricity after I left.
Nice save for your customer, getting those plate heat exchangers to seal can be a problem at the best of times I hope it works for them there is a specific procedure for installation and torquing sequence and specifications for the through rod studs. One failure mode I have seen is failure to clean the threads of both the nuts and studs before installing, oversized hardens washers helps lot.
Ref reducing chatter by machining in one direction only, possibly Y axis carriage is lifting/pivoting? As you say 3 inch cutter is a good size, certainly bigger, and with tungsten carbide to boot, outside the thinking of Messrs Bridgeport. Useful machine. Thanks for sharing.
The cutter is supported in one direction by the full mass of the planer head pushing against it while less supported in the opposite direction. This is likely the cause of your chatter. The Bridgeport head is a much better utilization of a small planer than the older single tool method.
Watching the video and seeing it in person, it's amazing the differences. What finished out as a very smooth, about a 125✓ surface, actually looks horrible on camera.
A tee nut underneath in the middle with a bolt in it would of killed the vibration, or a small screw jack. Did better then I expected, I thought that full width first cut was going to scream. Good job!
I think you should get a Bridgeport type head with a number 40 taper. I do like your milling cutter. I have been really pleased with them in a shop environment. I bought one for home use. Also any planer that I have used the milling head is mounted to the compound slide of the planer. The tool is moved up and down with the compound slide. The rail is moved up or down depending on the height of the work piece and the bolts locking the rail in place.
I put on what was readily available. I have been watching for something better, but most of what I do on here doesn't require anything more than an R8.
Yes big return on bio gas generators using digester. Another option is small gas turbines or up to the cousin of the mighty GE J 79 turbojet engine with afterburner, the land marine version LM 1500 light weight no afterburner yet produces over 15,000 hp, then the final exhaust steam is used to make dry high pressure steam. I sure would follow this start up company, You might get a lot of new future business. Great work Mr Topper
They have apparently been here 15 years. First owners bankrupted it and it sold to a new company who is growing it. Very interesting and I look forward to seeing it grow
When you reached the end of the first pass then started feeding back the other direction I was a bit surprised. A planer would b engineered and built to withstand force in only one direction, so the increased chatter isn't surprising. I assume they couldn't flip the plate around and use the other side? If it were a situation where the pits need filled/removed, and there were limits on the amount of metal that could be removed, Belzona products are worth considering. Seriously expensive but they seem to work well in chemical process repair. Jobs like this could give you an excuse to look for a big old Blanchard grinder😂
It's actually not as rigid as you would think. It is absolutely best for small cuts and large pattern drilling. But if you take your time and know its limits, you can still do great things. I wanted them to just let me make a new one, but they insisted on milling this one. I honestly have no idea why they just didn't flip it. It was symmetrical, should have flipped just fine.
The end plate looks symetrical Josh. I would havs suggested that they just turn it round and put the outside on inside. I know it'd be a lot less work for you but would cheaper for them. I found my customers always liked it when I suggested a cheaper option for them.
I know we're relying on the audio quality of the video but that facemill sounded super quiet. That machine is nice and rigid but that cutter sounded great.
I'm surprised youre not using side clamps... so useful especially for surface operations like this. It wouldve been flat on the table, no hold downs in the way, no shifting clamps... a one setup kind of deal.
I have OML eccentric cam system side clamps and they are fantastic on my Mitsui Seiki. But, that job would always end up bouncing up and down in the middle - you won't get that job flat, consistent in thickness and parallel by milling - the material is too thin and large in size. That job is a wash grinder job, if you want it done right.
I work in a dairy facility as a mechanic and we use the same kind of cooler. I just started there a few months ago so I'm not sure exactly what they do but we have pretty big ones. There's one that's something like 6 or 7 feet tall and about the same width as that one.
That sort of size of plate heat exchanger in a dairy is probably a pasteurizer. They are quite clever in that the regenerative section can recover quite a bif of the energy put into the syste. We had similar systems in the brewing industry, but considerably larger. When I was sailing as an engineer in the merchant navy some of the main engine coolers were huge.
@@TopperMachineLLC I was previously in the glass industry, we made plates and bowls. We didn't have much need for cooling other than just forced air from big air handlers. So this is my first time around these setups.
Sometimes the only thing that gives you a good finish without chatter is to use a fly cutter. Its time consuming but works well. You could also just leave one insert in your face mill and fly cut it like that. But that seemed to work pretty well with that cutter.
Just curious as to why they couldn't have just flipped the plate and used the other side? We do this on out plate and frame heat exchangers all the time to double their lifespan.
So out of interest - you mentioned flatness - did you measure the flatness, and do you know what flatness you can get off that machine over its whole work area? I am constantly making weldments that have surfaces that sort of size that need to be decked off flat after welding, to take off shrinkage and distortion allowance before machining in fine features.
I haven't had to use it for a real true flatness, but did check it once years ago. I seem to recall a 0.005 dip in the middle. Usually if there is a call-out for flatness, it goes to the HBM.
Josh, I’m kinda surprised the customer didn’t give you the gasket so you could determine what areas of that surface needed to be flat. I’m guessing most of that interior surface is just exposed to water which caused the majority of the pitting and plays no role in sealing - but I could be wrong. You have a great channel, wish you could show more of your locomotive work but I understand your reasons for not filming that.
The Part seems very symmetrical. Could it even be flipped without any machining? Also im surprised they didn’t have a last exchanger plate over the ends that provide the frame to protect them from the media.
No, absolutely no grinding in my machine shop. The dust is detrimental to the equipment. If it were completely wore out, then I could move it out and set it up as a grinder, but not in my shop. There are grind shops that I send smaller stuff to.
Why support the plate only at the ends, so the center can sag? Is the goal to have the center thicker than the edges? Little confused by this one…unless there are supports under the center of the plate that I just cant see.
A few 1-2-3 blocks in the middle probably would have helped with chatting , it it amazing how some things that are thick will bend and flex some even under light load . That machine sure can remove metal a lot faster now than it could have ever done as it was originally built to work . How long would have it taken to cut a 6" wide pass with a single tool bit ? A long time .
You are always interesting. There sure was a lot of damage. So did you take off a total of .125??? Thanks for the video. It is always good to see you. I enjoy your old videos to.
This is really a good video. I always enjoy watching your stuff, although I watching on my TV rather than on my phone, but I have to comment on my phone. Without mentioning numbers, how do you even price out a job like this? Is there some big book of machinist, standardized, pricing or something? I am always curious about that. And you never failed to surprise me with either a new piece of equipment that I’ve never seen before or a new use for a piece of equipment I have seen before. Keep up the great work.
Thanks for the comment. To answer your question, it really depends on the job. Mostly pricing is based on experience of similar jobs and time estimations. I have a set hourly rate for estimating and base the price on the time I think it will actually take. Some other factors that drive the price up is, how soon its needed and can anyone else in my region do it. For the most part I am the last shop around that can handle the stuff I take on, so I just set my shop rate to reflect that. Sometimes it drives away the customer, but eventually they come back because I am the only one who can do it.
This is the end plate of a plate cooler. Typically, all data plates, engravings and/or other information will be on that plate. I am quite sure that is the one and only reason the power company opted for milling the correct side.
If you would put a cup grinding wheel on the head it would be a very large surface grinder , or mount a grinder head on where the Bridgeport is mounted would be even better . I mount a portable straight grinder to a old radial arm saw to do some surface grinding once and it worked for the job at hand .
Man, I LOVE this kind of stuff. I can watch a machine work for hours. Question : the cut pattern looks to me like the head is ever so slightly trammed, tilting the head with the top away from the gantry, and the cutter towards the gantry. Is that true? I'm learning machining now (in my old age retirement), and am trying to understand cause and effects of what cut patterns I see. On my Lagun mill, when I can see the leading and trailing cut patterns against each other, I "think" I have the head trammed in correctly. But I am still learning from guys like you.
Yep should have placed it directly on the table or placed a support block directly in the center. That ringing noise should have told you.. keep on trucking 😊
Nice job. What if, as a last light finish cut you put the plate on the table and clamped it on the sides so that the top was clear than use a big fly cutter? Would that help with the chatter and overall surface finish? The plate being so heavy. Thank you and I always enjoy watching your work. Happy New Year.
I really like videos that show how your converted planner work. I have one question. Did you use lubricant on the cutting surface? If you did I missed it. That face mill looks like a very good investment to me. Looking forward to more videos from your shop. KOKO!
Update! I've had a lot of really dumb comments and arrogant "you should do this" comments. I chose the way I did it because the plate had a warp to it. It would not sit flat on the table. Instead of trying to pull the warp out and makng more problems, I chose the best solution for the given problems.

your techniques are always interesting and informative....
many ways to "get the job done right the first time"......
I appreciate your candor and the way you share information
with the rest of us......Thank You so Much......PB
Just tell them you are not telling anyone this is the way to do it
It is just the way you do it and it gets done right the first time.
Right on.
Simple rules…your shop, your machines, your client, your channel. They probably haven’t got any of those things. Hence the comments.
I have a lot of those in my plant. This is the way I would have done it.
Josh, I do not think I have seen you use this machine before.....
it is a very kool machine........cheers....PB
There are several videos of it.
how awesome is to see this old machines still being useful and productive in a real world machine shop environment.
My CNC router is soooo jealous. The strength. The rigidity. The Y travel.....
The plate looks like it could just be flipped and used. However, I see your comment that it was warped so you fixed it the best way possible. Thanks for posting.

But, that job would always end up bouncing up and down in the middle - you won't get that job flat, consistent in thickness and parallel by milling - the material is too thin and large in size. That job is a wash grinder job, if you want it done right.
Very cool machine
Talk about the ideal job for a planer.
Yes, if only someone before me hadn't stripped the planer drive and clapper off of it. I wish I had a big planer, but this works.
Another good video!
It would be interesting to see this plant if you get a chance to shoot any video. It sounds like it's quite unusual.
I got the tour, no filming allowed unfortunately.
@@TopperMachineLLC It would have been interesting to see how it all worked.
It sure was.
well that was definitely an etching oopsie .......I wonder how deep it would be before it needs replacing.
Good stuff thanks for sharing
I tried to convince them to just make a new one, but they wanted to save it
I guess a good solution might be to cover it with 316 stainless
Nice job.
BTW a sneaky trick is to plop a RO sander with the velcro pad on top of a scotchbrite pad. It has just enough grip to work.
I work in a dairy facility as a mechanic and we use the same kind of cooler. I just started there a few months ago so I'm not sure exactly what they do but we have pretty big ones. There's one that's something like 6 or 7 feet tall and about the same width as that one.
I've been around a lot of these. I've actually seen ones bigger than you described.
That sort of size of plate heat exchanger in a dairy is probably a pasteurizer. They are quite clever in that the regenerative section can recover quite a bif of the energy put into the syste. We had similar systems in the brewing industry, but considerably larger. When I was sailing as an engineer in the merchant navy some of the main engine coolers were huge.
@@TopperMachineLLC I was previously in the glass industry, we made plates and bowls. We didn't have much need for cooling other than just forced air from big air handlers. So this is my first time around these setups.
@@billdoodson4232I think you're right about the pasteurization thing. I remember them saying that's the room they're in.
Sometimes the only thing that gives you a good finish without chatter is to use a fly cutter. Its time consuming but works well. You could also just leave one insert in your face mill and fly cut it like that. But that seemed to work pretty well with that cutter.
I certainly could have done that. Set it up and walk away.
handy mill that, that would earn its keep quite easily.
Paid for itself the very first job.
Just curious as to why they couldn't have just flipped the plate and used the other side? We do this on out plate and frame heat exchangers all the time to double their lifespan.
It was suggested and this is what they wanted.
So out of interest - you mentioned flatness - did you measure the flatness, and do you know what flatness you can get off that machine over its whole work area? I am constantly making weldments that have surfaces that sort of size that need to be decked off flat after welding, to take off shrinkage and distortion allowance before machining in fine features.
I haven't had to use it for a real true flatness, but did check it once years ago. I seem to recall a 0.005 dip in the middle. Usually if there is a call-out for flatness, it goes to the HBM.
Josh, I’m kinda surprised the customer didn’t give you the gasket so you could determine what areas of that surface needed to be flat. I’m guessing most of that interior surface is just exposed to water which caused the majority of the pitting and plays no role in sealing - but I could be wrong. You have a great channel, wish you could show more of your locomotive work but I understand your reasons for not filming that.
The Part seems very symmetrical.
Could it even be flipped without any machining?
Also im surprised they didn’t have a last exchanger plate over the ends that provide the frame to protect them from the media.
I second this, more pits more surface area, better heat transfer
Topper *Would be neat if you posted on the video the RPM's you're running on a particular pass.*
Candidate for a lumsdone or blanchard grinder me thinks. Could they not use the other side for the sealing face.
The part looks great. ❤Happy New Year’s.🎉
Is it possible to put some type of grinder head on that Bridgeport maybe even regular hand grinder?😅.
No, absolutely no grinding in my machine shop. The dust is detrimental to the equipment. If it were completely wore out, then I could move it out and set it up as a grinder, but not in my shop. There are grind shops that I send smaller stuff to.
Why support the plate only at the ends, so the center can sag? Is the goal to have the center thicker than the edges? Little confused by this one…unless there are supports under the center of the plate that I just cant see.
I just found your channel, glad I did! Looking forward to seeing your others, take care!
I kind of wonder, could they not just turn it over? What did the other side look like? It doesn't seem to be keyed to only go one way.
I suggested that and they rejected the idea.
That was enjoyable to watch, thank you
Would it have been possible to turn it over and machine the other side?
They wanted this side trued. Trued offering many options, this is what they wanted.
A few 1-2-3 blocks in the middle probably would have helped with chatting , it it amazing how some things that are thick will bend and flex some even under light load .
That machine sure can remove metal a lot faster now than it could have ever done as it was originally built to work .
How long would have it taken to cut a 6" wide pass with a single tool bit ? A long time .
Yes, but as a planer I could have just set it up and let it go. I really wish it was still a planer, but it was already converted when I got it.
Maybe some day you can find a planer in good original condition for the shop .
Each has it advantages .
You are always interesting. There sure was a lot of damage. So did you take off a total of .125??? Thanks for the video. It is always good to see you. I enjoy your old videos to.
Yes, it was about 0.125. I was surprised it cleaned up as well as it did.
Why wasn't it bolted flat on the table the first time ?
Hi, would a bigger fly cutter make a nicer surface finish??? Plus be less chattering?
Awesome video thanks
This is really a good video. I always enjoy watching your stuff, although I watching on my TV rather than on my phone, but I have to comment on my phone. Without mentioning numbers, how do you even price out a job like this? Is there some big book of machinist, standardized, pricing or something? I am always curious about that. And you never failed to surprise me with either a new piece of equipment that I’ve never seen before or a new use for a piece of equipment I have seen before. Keep up the great work.
Thanks for the comment. To answer your question, it really depends on the job. Mostly pricing is based on experience of similar jobs and time estimations. I have a set hourly rate for estimating and base the price on the time I think it will actually take. Some other factors that drive the price up is, how soon its needed and can anyone else in my region do it. For the most part I am the last shop around that can handle the stuff I take on, so I just set my shop rate to reflect that. Sometimes it drives away the customer, but eventually they come back because I am the only one who can do it.
This may be my lack of knowledge showing, but the plate looks symmetrical, so why don't they just turn it over?
It was suggested but rejected by the customer. They wanted it smoothed out.
Maybe for future works, get a magnetic adapter to hold the piece and skip cutting so close to your clamps
Love this channel, one question, the plate appears to be symmetrical along its length, why not just flip it over and use the underside ?
Great question. They wanted to mill it, I have no idea. It was suggested to save them money, but this is what they wanted.
Glad to see someone asked the same question I had about 2 minutes into the video. That just what they wanted. Roger that. On with the video.
This is the end plate of a plate cooler.
Typically, all data plates, engravings and/or other information will be on that plate.
I am quite sure that is the one and only reason the power company opted for milling the correct side.
@@johanea I'd bet you're correct. I never looked at the other side, but I bet it was stamped with data.
@@johanea Sometimes the data plate can be the about most valuable thing on equipment in regulated industries
If you would put a cup grinding wheel on the head it would be a very large surface grinder , or mount a grinder head on where the Bridgeport is mounted would be even better .
I mount a portable straight grinder to a old radial arm saw to do some surface grinding once and it worked for the job at hand .
Absolutely not. I want to keep my machines in good shape. Grinding destroys them.
Did you ever hear of a surface or Blanchard grinder???
Stupid question, would putting a couple of 3,2,1, blocks under in the middle stop the resonance?
Man, I LOVE this kind of stuff. I can watch a machine work for hours. Question : the cut pattern looks to me like the head is ever so slightly trammed, tilting the head with the top away from the gantry, and the cutter towards the gantry. Is that true? I'm learning machining now (in my old age retirement), and am trying to understand cause and effects of what cut patterns I see. On my Lagun mill, when I can see the leading and trailing cut patterns against each other, I "think" I have the head trammed in correctly. But I am still learning from guys like you.
Ideally this is a perfect job for a Blanchard grinder, but have to use the machines we have.
Yes, or an actual planer. None of which exist around here.
Yep should have placed it directly on the table or placed a support block directly in the center. That ringing noise should have told you.. keep on trucking 😊
Why didn’t you clamp it flat to the table?
The workpiece looks to be symmetrical. What did the opposite side look like?
Why can't you fill the really deep spots with weld first?
Could you have put weld in the deep ones?
I could have, but the customer was pleased with the outcome.
Would have been a good job for edge clamps. Or even the old school planer clamps.
Could this repair be done on a Blanchard grinder? Or a long bed surface grinder? A magnetic chuck could help with chatter problems.
Sure it could, but to find one in this region would be impossible.
Nice job. What if, as a last light finish cut you put the plate on the table and clamped it on the sides so that the top was clear than use a big fly cutter? Would that help with the chatter and overall surface finish? The plate being so heavy. Thank you and I always enjoy watching your work. Happy New Year.
Plate was wider than the table. I could have just done it in the boring mill but chose this way instead.
The chatter Almost sounds like a loose pulley in the j-head had a similar issue was a simple bushing in the j-head
You need some cam clamps. They would have been perfect for a job like this.
Part was wider than the table, otherwise I would have.
Looks great to me. Excellent. 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
I noticed a little smoke coming off of it is the plate or cutter getting hot?
Burning the paint. Plate warmed up about 10°F during the whole job.
I really like videos that show how your converted planner work. I have one question. Did you use lubricant on the cutting surface? If you did I missed it. That face mill looks like a very good investment to me. Looking forward to more videos from your shop. KOKO!
No coolant or oil. Dry machining works just fine on most applications.
