Hopefully Bozo stays away, Keith!! Love your videos!
Beautiful how smooth and true that cut was just setting the axis to zero and not tramming the head in.
I thought the same thing
I couldn't believe he didn't tram the head. I shake my head at some of the things he does/doesn't do.
Was that why there was +/- 5 thou when he measured thickness? Looked like the 12/6 oclocks were thicker than the 3/9 oclocks from those holes...
"Beautiful how smooth and true that cut was..." Unfortunately shiny does not equate with precise. Sometimes the old adage, "it's better to be lucky than it is to be good" is good enough but I wouldn't want to bet a SECOND set of costly parts on it. These videos are for the most part entertaining, though, if not exemplars of how things should be done properly to make parts that are both shiny and precise.
Also, is it me, or are these videos getting ever more light in content? This one was a slipshod setup and simple milling of two faces. At least he could have machined the vertical surfaces as well to make a slightly more content-rich video. Is the time coming when we get a video titled, "Tightening a nut on the (insert machine name here)"?
And finally, last week he mounted the all angle head to the machine and from all we could tell the drive gears were installed completely DRY. I hope he dismounted the head again and added a bit of grease or other slickum to those poor gears!
I used to run Cincinatti converta mills and I would tram the head in and with a very fine scribe I would scribe a line on the little plates where your graduations to changed angles were. They were aluminum and it was easy to scribe a fine line on. If I were really trying to split hairs I would tram it.
Keith, I love your videos and watch every one of them, and I deeply respect and learn from the work you do to keep great old machines in good repair. Now, I know I'm saying this from the comfort of my office chair, but... I was expecting you to tram the head a little more precisely than would be provided by the degree scale, especially with a milling cutter that is as wide as the one you used. Aaaand...those table clamps being so tight with as-cast surfaces down on the table would surely have distorted those castings some. You had at least .010 difference in thickness just around the holes after milling the second side. Maybe that's within tolerance, but this is the second set of castings, so just sayin'...
The surfaces he is milling are in practice only cosmetic and their machining is for looks and to make future setups for the important operations easier to perform.
Did the head have to be trammed? Was wondering how accurate the degree markings were. Great video.
I wondered the same thing...
It should be, but not doing something like that is how we roll here. Like the machine rocking all over the shop when he tightened the pieces to the bed but it is what it is.
Interesting demonstration of that K&T universal head. Looks like it has a ton of potential uses. Nice work! Thanks for the machining content. Always good stuff here.
That was smooth cutting machine. No bangs or clacking.
Have a good weekend Keith.
Good morning Keith
Don’t you need to tram in the head. Are those angle markers that accurate?
Yes and no they aren't
That was my first thought.😊
How do you have a universal head on that machine and not have to tram it in?
This is the second video of the machine where I thought I saw the mill tilt or move when he was yanking on it. Knowing that Keith does the leveling so well, I'm trying to figure out what I'm seeing.
I paused the video and came to read the comments to see if anyone else commented on that as well. Maybe he has not leveled it at all yet.
Wonder how flat is the surface. We always tramed the table after setting the head. Probably within tolerance?
That machine can do anything! It is incredible watching the whole process from sand casting to machining in 2023 for a steam locomotive.
given the age of the locomotive I am surprised the planer you put so much work into didn't come into play on this job. I have wanted to see that in use for a long time. But you have your good reasons I am sure, keep up the interesting work!
Clarke at Windy Hill Foundry really knows his stuff.
Those castings don't have even one little hole in them.
I'm no machinist, and just have an old student Clausing mill, so when you casually said you were going to take a 100 thou cut I was pretty surprised. This thing is a real beast.
In his younger years, my dad was an excellent 👌, self taught machinist, mechanic, watchmaker, carpenter, steam engineer, and everything else 😀 💙 😉 mechanical!
There is something to be said for a heavy robust machine - they just work - no vibration or resistance! Great Video as usual - I always learn something from your videos!
That thing is a beast!
We had two Milwaukee mills in our vokie school machine shop and the tool & die shop. I had lots of time on these in the three years plus our freshman trials year. After graduation I never used small mills just the giant ones that cranes had to mount the work pieces. But those gave me the foundation to build on.
Thaks for sharing yet another episode
Thank you for sharing.👍
love seeing the old machinery being brought back to life!
Always a pleasure to watch your calm approach Keith.
That Milwaukee is amazing. It can do a bit of everything. Ok, it would struggle with very small parts, but... lol there's Blondie & Co for that.
It has a built-in mini crane too, to swing that gearbox in and out. Good to know it will be kept up. That thing is a monster.
6am coffee and arm chair machining 😆
Awesome Kieth. A joy to watch
Thanks for sharing
Thanks for sharing 👍 Watched these bearing being poured.
Good morning Keith. Glad it worked out this time. Looking good. Thanks for the videos.
Very nice Keith.
Keith, was that the camera rocking or was the mill rocking on the floor? Also, did you tram the head, or just use the markings?
That thing is a beast.
Love the old machines especially there history
so you got the parking attachment set up right did you end up putting a thrust barring under the Maine arm so it will move for you just asking is all should know better as i know you never answer anyone cheers
Keith, I know you wanted to try out the universal head on the milling machine, but you could also have machined them on the lathe in a 4 jaw chuck.
I wish I had your milling machine, and you had my feather,, we'd both be tickled.
Thanks again for the videos !!!
love to see the vertical head being used. I was told k and t made the side of the head machined to a point where u could run an indicator up and down it on that big flat spot and basically tram the head in without using some kind of tramming tool. It looks like just putting the head to zero on the scale gets u where u need to be without doing any tramming or such.
you have some pretty impressive "toys!"
Watching this is as close to being a machinist as I will probably be able to be; I thoroughly enjoy 😉 😀 watching you do the machining!😅😊
Watching "The Keith's" and others machining always makes me wonder if I had been better off to become a machinist instead of a Mechanical Engineer! My Granddad was a Machinist for Lockheed (then Bell Aircraft) here in Atlanta (Marietta) in the '40s. He did sheet metal work making instrument panels for B-29s before/during/after WWII. From the time I was little he would always tell people I was going to be an Engineer and I never really considered being anything else. Having said that my Degrees (2) are in Mechanical Engineering Technology which is more "Hands on". We weld, know our way around the machine shop, etc. We're the ones that can design something and then go build it. I HAVE generated a few 55-gallon drums of swarf in my time though (now retired)... 😁
Great practical video. Surprised you didn't tram the spndle square. Must be a reason?
Nice
Keith, another wonderful video…. Thank you sharing your time and many talents. Can you show the blue prints periodically and give us your thoughts on the order of operations?
Say, whatever happened with that automated coal transfer box casing you and Abomb were trying to machine the inside of? Must have missed an episode. What a great channel. Thanks
Nice!! 🙂
Keith, I'm always surprised that you don't use much cutting oil in most of your machining operations. I admit that my machining days were quite a while ago but I suspect my High School metal shop teacher would have a fit if I didn't use something, and we were working mostly in Aluminum.
Just curious that you didn't tram the head and got lucky on the cuts.
Did you tram in the head off camera? Seems you never even checked the alignment.
Nice job working the bronze castings.
Thanks for sharing.
PFFFFFFFFT. You just wanted a reason to set up the parking attachment. 😁
that machine is a real beast. fun to watch it operate even with Keiths conservative approach. im screaming inside hog that material off! it can handle it.
I took note on your last video about mounting the parking attachment for the milling head you used today
You were having a lot of trouble swinging the head over to the front of the machine. I could see the attachment point (swivel) for that arm to the parking block was very slightly tilted. At least it seemed to bind from the weight on that hinge point.
I thought that if there was a flat washer in that hinge joint that the surfaces would move much more easily. That washer could be made from an oil retaining bronze so it would be very slippery yet still put up with the weight it is asked to manage. There seemed to be enough adjustment in the arm setup to allow for the bit of extra space the washer would take up.
I had the exact same thought while watching. Kudos!!
I always look at your work with great interest. I noticed, at 9.35 minutes and further in time, is the milling machine rocking? This is probably not entirely normal...
I watched it 3 times and seen no movement maybe your monitor is flickering?
At the moments when the nuts are tightened. @@briand01
@@briand01 Look at the top right of the video as he tightens the clamps.
Nice. Now let's see how to get the sides perpendicular to the face.
Hi Keith, Would another method for facing the bearings would be to chuck in a lathe using the center bore? That would ensure the sides would be inline with the bore.
This one is a bit bigger than the watchmaker's mill😁
Hello,😊
Keith, I noticed on this video and the previous one that your machine is not sitting solid. It appears (correct me if I am wrong) that it wobbles when you tighten and loosen any bolts. You will not get the best surface finish if left like this. I couple shims will solve this.
I noticed that also
the rigidity of this machine has nothing to do with it sitting on the floor. it could hang from a hoist and work the same.
@@MrChevelle83......Absolutely NOT true!
@@MrChevelle83 Take a 10 Tho cut at the recommended RPM 1/8" end mill and then take a 100 Tho cut with a 4" face mill at the recommended RPM, machine hanging in the air.
@@MrChevelle83 Odd... wonder why it has floor-mounting points cast into the base. All this time I've been falsely assuming it's meant to be shimmed and bolted into deep concrete anchor in the floor! 🥴
Like such!
You mill looks like it has its Halloween mask on!
Keith, it seems like your milling machine is rocking. Am I not seeing that right?
Keith: At 4:50, when you were rotating the adapter to vertical, I noticed the whole mill moving, as though the feet were uneven on the floor. Were my eyes deceiving me? You may want to re-check your machine for level. Thanks for the video. See you at the Bar-Z. Jon
Is the parking attachment designed to flex like it did between 11:48 to 11:52? Just above that gray cover with the vent holes it flexed a lot 😨
Why not thicknessing these on your period-accurate metal planer?
that knt is a brute. it would be cool to put a big piece of steel on there and just hog some metal off to see its capabilities!!
👌👌👍👍
Is that milling machine in the back ground a model D? How is it doing?
I'm curious do you still have that large radial mill?
so whats the scoop on the capstan for tallyho?
WHAT..!!!!!
Did I hear you correctly,,, you,, Keith Rucker spoiled the work..???
I can’t believe it..
Never in 1 million years would I would have thought to hear something like that…
Oh well,, I guess that just goes to show you that even the best of them F up from from time to time..🥺
I suspect the milling attachment will never be in the stored position.
Anyone who gets this guy to do anything with a level of precision is a fool. He didn't pack the parts with shims underneath to prevent the clamps from distoring the material which after milling the top could spring back and throw the flatness of the milled face off. He didn't tram the machine which is why the parts are not parallel after he milled them. He also does not have the machine properly leveled and secure to the floor.
That parking attachment flexed a heck of a lot. Better to make bushings over the studs for tightening down the overhead cams. I can easily see that casting snapping. 1/8…sure..1/2 like that…uhh no.
I suppose he never read the comments
I would have trammed the head in with relation to the axis travels. I hope there's enough material to ensure getting the slots in the side of the casting equal distant to each other and centered in the track that it will need to follow, I hope I can be understood.
I thought the same, surfaces on the table (horizontal) may be hollow in the centre, and the parallel surfaces (vertical) may not be parallel to each other.
machine base needs a shim under a corner
My old Forman would have shot me for not having over arms fully located 😮
Could you have milled the edges without disturbing your set up , just change the mill?
Your hands are not hammers!!!
Everything is a hammer, unless it’s a screwdriver. Then it’s a chisel.
@@grntitan1 Ha! That's a good one.
Meat hammers
I totally agree
Ya know, it's kind of hard to watch an untrammed head with a huge cutter just chomp into a set of castings that took multiple attempts for an overbooked foundry guy to produce. Add to that all the unknowns of rough casting surfaces muscle-clamped at a center point that could easily act as fulcrum point while their widest edges hang out in space over open T-slots? If those things came out even remotely flat and parallel, it was a divine miracle. But hey, what do I know? Maybe back in the day these things were made, a tolerance of +/- 100 thousandths was the best you could hope for and this is well within "good enough"? No clue, but it sure looks like a good recipe to accidentally scrap another set of bearings 😬.
Joel, would you be kind enough to provide a link to your video showing us how you do this the proper way? I always try to learn from the best. Thank you!
What I dont understand is, You Chose this machine because it's more rigid, BUT in the very beginning you go to rotate the head the whole machine is teeter tottering where the levelling feet arent all on the ground? How can that be good?
No...of course it's not good.....by ANY standards!
I assume you trammed that head off camera
Definitely need to tram the head in every time it's changed.....the fact that you didn't would explain the varying measurements you found when measuring the overall thicknesses. That...and not shimming the parts solid to prevent movement and flexing.......and not leveling the machine on solid supports!
You should take some time and clean up those areas on your machines so you can see any markings and/or numbers on any scales so you don’t waste as much time struggling to see the markings when you’re setting up for cuts or milling.
(markings) do not mean accuracy, the head should should have been trammed, especially with a universal head. vertical and horizontal issues. Accuracy and procedure does not appear to matter in allot of his videos. The old timers who machined the originals would be turning in there graves if they were able to have watched this set up, precision and QC.
I'm
Keith, I love watching your videos, but it hurts me every time, when you use your hand as a hammer. Please try to avoid it.
Hope your next bushings were not shipped by FedEx. We ordered an expensive printer for a relative and it came by FedEx. We have a sign in our driveway that says "All FedEx and UPS deliveries are to be made to the top of the ramp at the home behind" Well, this FedEx, like most FedEx ground contract drivers, especially the ones working for a Chicago company, cannot read a bright yellow sign painted on a large stopsign blank with the message.
This idiot put the printer on the implement trailer sitting in the front yard of the old house and it was raining. Thank goodness, Amazon made a mistake. They sent the printer from their stock by UPS and the printer mfg, sent one by FedEx and it got wet. Amazon is doing a return by UPS of the FedEx-delivered printer.
We do not have a UPS store within a 120-mile round trip so we will make a 65-mile round trip to take it to a Kohls store. We included the part about the stupid FedEx driver and his putting it out in the rain in the return reason. Hope they check it before sending it out again. At least the box was one of those shiny printed boxes so maybe the printer did not get wet.
FEDEX SUCKS SWAMP WATER AND THEIR CONTRACT DRIVERS SHOULD BE SANK IN THE SWAMP.
Keith I'm going to have to guess that your shop is getting pretty full of equipment.
