I use a Scotch-Brite pad with some wd40 on an inexpensive sheet sander to get rid of the rust.

Having rebuilt many Bridgeport’s through the decades, a couple of tips might be in order. Bridgeport is now owned by Hardinge in New York. They have every part for this machine in stock. The wipers are NOT leather. They are felt. Leather will trap chips behind them while felt collects them to keep anything from entering the ways. The use of grease isn’t that bad. Just think what it would be like without any lube. I didn’t catch what type of oil you were using, but “way oil “ should be used . I.prefer Vactra 2 or 4 . Extreme care should be used when dealing with any scraped surface. These are any surface on a Bridgeport that has been flaked. Any bruise should be dealt with using a stone . Remember these surfaces determine the precision of the machine.The head is another ball of wax with a lot of little tricks to do is easily and right. Hardinge has parts lists and assembly drawings on line. Good luck with your “new”Bridgeport. By the way all of the debris in the saddle is normal. It makes its way there at the small space by the knee axis
Yeah I noticed that too. Grease won't kill the ways, it's definitely not as good as proper way oil but it's better than bare metal on metal!
And the chips getting everywhere is basically unavoidable, stuff gets into absolutely anything and I've seen much worse than this machine!
That's cool. I had no idea all of the parts are available. I'm picking up a mill soon and thought I'd have to source parts like it's an old car.
@JC4crs I looked a little for that Lube8. Where are you getting it? What brand is it?
Thanks for sharing the Hardinge note, I had no idea! Also, the Felt - you are right about. I used leather once on my workplace mill and it got worse.
There was nothing wrong with your DRO after your clean-up! Get the manual and read about the Memofix feature which enables the 0,0 datum point to be fixed even after a power off. It 'remembers' where the datum point is so when you resume working you can start at the correct place again. You had the Memofix switch on and the red light in the display was on. In the Bridgeport manual there is a section on how to use the Heidenhain DRO properly.
I worked a Bridgeport for many years and it was nice to see you give it new life. The strips you cut for the cross slide should be a one piece unit to clean the whole cross slides front a nod back,hope this helps.👍👍👍
And they’re still available
Safety tip, please remove your hoodie when using the mill, getting the strings caught in the cutter will be the last thing you do.
yeah
your right
@Gabriel Burningham nope. no one cares.
I don't think I have ever seen a complete machine rebuild in a single video before. Just a side note: that power feed bar that runs down the front of the table can get in the way as well as mounting the DRO scale on the front rather than the back of the table. It might not let you consider hanging a part down on the front side of the table - a feature I have used several times before. Overall - well paced, fast when it needed to be a slow when explaining. Really enjoyable.
excellent video. Altough the use of the selfstick did make me dizzy at time. I've got a lathe and a similar mill at home that could use a treatment like that. No DRO's though :-)
That is the equivalent of cleaning a whole house so good job
Great clean-up tutorial! I used a Bridgeport about 20 years ago when I worked as an Engineering Technician. I learned on-the-job and it was kind of scary at first, but once I gained a comfort level with the machine I really enjoyed using it. It expanded my knowledge of how to make things and I was blown away at the skill of some of my older co-workers. They freely shared their knowledge of how to properly do things with me. Since that time I have had the desire to get one for my home garage, but that's still a fantasy at this point. I have two cars in my garage and there is no room for this type of equipment. However, my hope springs eternal that I will create my own home workshop at some point. Thanks for the video!
Thanks a million! Just got my first BP today - a Series 1; three-phase; original power feeds and vise! Just got it set and leveled; gonna do exactly what you've done here.
It will be interesting to see the accuracy of the ways and table
Great seeing an older machine being brought back to life, great work!
16:23 I'm fascinated by builds/rebuilds like this but I must say the squeegee find was simply brilliant on your part! bravo!
I used to work for a tool and die maker and we'd sharpen endmills all day ling for the machinists in the area. I remember walking into large machine shops and seeing 30-40 Bridgeports all lined up on the floor cutting parts assembly-line style. This video brought back a few memories. Well, it was only one in your shop but....
You can never replace that look you get cutting those first chips :) Congrats and nice job
This warms the heart of a Toolmaker, have 1000 of hours in a bridgeport, wonderfull machines !
For what its worth, Heidenhain scales need a very specific gap set. If you do not set gap properly, they will cause that jumping and glitching.
This milling machine's condition is not bad.Look these hand-scraping marks on the guides,they are pretty shiny.
Jeah i got lucky, the ones on the x axis are in great condition! The ones on the y are a bit worn tho.
Alex nice job , with just hand tools and patience and elbow grease, you brought that mill back to life . The important thing to remember is to start with a good machine ..
Thanks Pete!
Man I am impressed. You really put that thing through the full monty, stripping it down. Great job.
Hi there, I just had my new to me , 2nd owner, delivered yesterday, as dirty as yours, been racking my brain on how to clean the bed, Scotchbrite red on a sander was a flash of inspiration for me! Thanks for that. Looking to buy a power feed, I have a few leads. If I can get my baby looking as good as yours, mission accomplished! Great video, thanks for the ideas!!!
Actually, that machine is actually in really great shape, and not very dirty at all. I would kill to find a machine in that condition for a good price that i could "restore" by wiping down with some degreaser and shoveling out a little pile of chips. Seriously bro, you won the lottery on this one, you have no idea.
Absolutely superb rebuild, patience and skill get results. Bravo!
Thank you very much :)
I have the exact same machine from 1964 at home. I mechanic on machine tools every day, believe me, it's not that dirty!!!!!!
That grease did have to go, for sure.
Nice video, I hoping to see the side by side comparison at the end but I just went back to the beginning. I learned from the video so it was great for me. Thank you Alexandre
We have a 64 step pulley j head at works with the original saddle and table. Has a lot of hrs on it. I put a variable frequency drive motor with a Hitachi drive box, servo knee feed, x axis power feed and a mitutoyo dro on it. And now it gets used almost every day again. Amazing machine tools
Great job, that mill was in really good shape under the grime. I was shocked that the electronics still worked.
Kudos, I took some machine shop classes when I was younger, and even worked at some jobs running various mills, some CNC and some not. The mills I used in training were immaculate the ones I used on the job less clean but serviceable. I cannot for the life of me, figure out how someone could use grease on the X and Y axis surfaces. The fittings used to put oil on those surfaces are commonly used to press grease in to an area so I guess. Those fittings called a Zerks. I watched you clean and thought of the smell oooh so bad. good job and good luck.
Cool video.... I’ve done this once before years ago, so I know what you went through. It was nice to see the process speeded up....
Quality work on a quality machine. Awesome videography to boot. It's good that machine ended up in your hands. No doubt you'll keep it in good working order for years to come.
Thank you :) I will try my best to take good care of it :)
If you need instruction in how to use it, Tubalcain has a series of videos that will go over all the different functions as well as techniques, etc. I had a Norwegian friend in college, and he used to pronounce 'together' the same way you do. Brings back memories. Keep up the great work!
I can appreciate the bathing of the old workhorse. Great job.
A true labor of love. Great work sir.
Awesome job on the find and the cleaning!
I have to admit, having worked with Millicron and Bridgeport lathes for most of my professional career, I cringed when you took it apart (without a manual or familiarity with the machine), combined with not fully grasping the basis of 'accuracy' which this type of machine is capable of. Bridgeports are easily capable (in 'like-new shape') of recreating 0.0001" accuracy in replicated components...so just tearing it apart, scrubbing it, little 'sanding' here and there' can make them a total PIECE OF JUNK, quickly! When rebuilding a Bridgeport, the standard is to dimension critical parts (table, ways, etc.) by producing a 'baseline part' (make something to dimension first), so that when you rebuild the 'cleaned machine', you can make a duplicate part and see if you retained the machine's accuracy (if not, the replicated part can more-easily show you where your inaccuracy can be found...maybe a now-warped table, slack in the gears, worn out bushings that now can be seen as years of residue is cleaned away, making slack at various points, etc.).
As you did not baseline the original machine, other than making it aesthetically 'prettier', you have no way of knowing if your actions were detrimental to its actual purpose, had no effect on its accuracy, etc. This was not impressive, as viewed from an experienced machinist's viewpoint...you blindly tore it apart, cleaned it, and reassembled it...did I mention, I cringed when you took the Scotchbrite to the table? OUCH!
Highly doubt that its easily capable of recreating 0.0001" accuracy but go off
Retired toolmaker , I cringed also seeing the sandpaper. In expert hands tenths of a thousands in accuracy are achieved. These type of machines were what we had before super accurate and expensive machines came along.
In the right hands using the learned techniques very high accuracy can be achieved.
An expert on these machines in the day could make very good money. I live in a neighborhood of doctors lawyers and businessmen.
I appreciate the video, I'm in the midst of the same process with my 1952 Bridgeport
Absolutely loved the vid!!!!
Thanks dude 😁
Tip to keep the flakes out from inside the bottom part is to add a pice of rubber on top the slide parts below the table, both on the outside and inside, helps the dovetail leather wipers to get rid of the majority of flakes and grim. Hard to explain in text and you might already done it, but check out Alex Steele as he did something like that on his Bridgeport. Nice to see the mill in good hands though! 👌🏼
Perfeito!posta mais vídeos desse segmento, isso é fantástico!
Great job on the mill cleanup.
Love the squeegee wiper retrofit 👌
Much respect brother, I'm the same way as far as taking care of my equipment and other things,
if everyone took care of their property like this the economy would tank due to the huge drop in sales, since every thing would last longer, of coarse this would force the mfg. departments to start making things even cheaper than they do now which would not be good for the consumers, but since when have they ever cared about anything other than profits...
Nice and good old project Alexandre, congratulations for your new milling machine
Thanks John! I'm super excited to start making things with it!
@@achappel Yeah man, i wanna see that things :D
@@johnnzetrockk9404 those* things
Very nice looking mill. Should serve you well for many years to come. Lots of negative comments here about the handheld and X axis scale being on the front instead of the back blah blah blah. Nothing wrong with constructive criticism but some people are just flat out a-holes. Keep doing what you do and enjoy that mill. I just bought a 3 axis CNC knee mill and an Andrychow TUG40 lathe, and have been cleaning the crap out of them for a couple weeks now. Still a lot of work to go but well worth it. Congrats on your mill.
Love everything you did and especially the Squeegee for the DRO scales, brilliant and REALLY cheap and effective! You need to find something like the Squeegees, but a little more robust for the Y axis wipers. I don't think the leather is going to do a very good job over the long haul. As for the cleaning and properly lubing, perfect! It's really looking nice. Now it needs it's place where it's going to live, solidly anchored, leveled and your good to go. Machining is "all about rigidity" of the machine tool and the work piece. As long as you remember that always, things will work well. If you don't mind me asking, how much did you get it for? Great Job!
Nice restoration! Keep this type of video coming!!!
Thanks Jamey! I'll do my best :)
Bridgeport are a good light toolroom mill and very versatile they are also the most abused machine in most engineering shops nearly always overloaded and pushed past their limits and what they were designed for.
I know nothing about engineering, which if you knew my family you’d think that is pretty remarkable. However I love seeing any old machinery or tools being restored. There’s something wonderful about watching things being given a new life rather than sold as scrap.
I have absolutely no idea why think they have to be rude about the hand held camera. Yes you’re entitled to an opinion, and I’m pretty sure most creatives I know like to be critiqued. However, that is totally different than being rudely critical of a video most are watching for nothing.
Despite the aforementioned mentioned handholding capabilities the content was really enjoyable. I really like the grease gun/degreaser trick. I’m glad you got the digital thingy working and the milling machine looks the bee's knees. Well done.
Great job ! Thanks for sharing your experiences . Thumbs Up.
Thank you :)
I bought A Bridgeport 20 years ago that was older than yours. Yours is not that bad of shape now that you have cleaned it up. Any future restoration projects I think making use of laser cleaning will significantly speed up the process. You can use the laser to degrease it and remove any rust or build up.
Nice machines, worked with them for many years
Great informational video! Thanks
Your vids are sooo satisfying...♥We Love Your energy and the Lovely Person You are♥ Love & Blessings from The Netherlands ♥Warm greetings from Kim
I would glue the ends of those rubber strips for the glass scale covers together. I think super glue would work but there’s probably a more specific glue for rubber to rubber.
I love working with a Bridgeport !
Good job guy. You really did bring that machine back to life. I like the music too.
nice bro its great work cleaning and make ready for work. i am waiting for your next video with the Bridgeport on new projects.
Thanks man!
I enjoyed your video, lMO you did not restore the mill, you cleaned it.
Well, cleaning becomes restoration after a certain point - don't forget he fabricated some new bits, even if they were 'only' rubber dust skirts. I definitely don't feel clickbaited.
Awesome job man! Really cool video. Don't listen to the haters criticizing your camera work or whether or not it's "a real rebuild."
I really like how you slap metal surface 😂
Haha time to clean that vise too!
Very good explanation !
Nice job! I would replace your leather way wipers with the correct felt material.
Agree with Dudley Toolright... The glass scale should be mounted on the back of the table. That way... It's less prone to damage and... you can use the t-slot to mount an auto-stop for the power feed.
Nice job! However I would've loved to see polished bits and the whole thing repainted. It's just so much satisfying to see things restored good as new or better. Love your work though.
Amazing video! Good job.
Good video. Would love to have a Bridgeport machine like that.
What a nice machine!
great video man. I am about to do the same thing and this will definitely be a reference. and I love the 80s music! Subbed
Nice job. Mine could use a good rebuild. You will love that machine.
Keep on restoring stuff! I really liked this video! Can't wait to see a project with the bridgeport ❤️
Thanks man :) I'm working on another little restoration project right now! 😉
White t-shirt ! Great idea 😁😁😁😁
Brilliantly done
Lookin.good.sir , as a diy guy my Model J needs a scale for a guy who uses it once in a while which is a good way to go ty subbed
Great video on the Bridgeport. Many years ago I used a J Head Bridgeport on my job. But now I'm retired and trying to save up enough $$$ to buy a Bridgeport to accompany my Logan lathe. But it seems that most used machines are in the North or West coast, and shipping is expensive! (I live in NE Georgia!)
check ebay.
Great video. Very informative thanks 👍
On my second Bridgeport, I had the pallet unloaded out onto a large tarp in the back yard. Did some disassembly, spread out the parts and pressure washed the thing with liberal use of degreaser. It just takes WAY too long to get it clean with spray bottles and rags.
wxfield jeah man! That sounds like a great idea! Did the same to a smaller lathe I bought, although I used a car wash next to my shop 😅
@@achappel Genius!! Now that would make for an entertaining video. "Taking your lathe to the car wash".
Well done Alex .
Nice machine- British made Bridgeport J head. Ive got a vey similar machine myself but yours look in better condition to mine
Jeah I'm really happy with it :) I honestly thought it was in worse condition when i started, so i got a bit lucky there:)
I like to see old bidgeports get new life but sometimes the ways need work because of lack of care and lubrication on the machine for many years. Its easy to take things apart but sometimes people are not able to put them back together. Having manuals helps.
I know an old Bridge port in Sheffield England that needs a similar treatment (but at least Richard knows about the oil, NOT grease issue).His has some extra features and the shaper attachment and the cutting fluid catchment cone. Almost all old machine tools are full of chips and sludge, most of it VERY old. I know that because I have stripped and moved several of them. BTW - that is the SHORT version of the bed!
GET a stabiliser for the hand held shots, or it will give people motion sickness. You have lovely ideas - so let people see them.
Ingenious use of the squeegee rubber. Another possible source of rubber, that would give you one piece for the length, might be greenhouse door sealing strip.
Oh that's a great idea! I'll check that out :)
Great job!
Great work
Hi I spoke to a fitter and turner about your mill he said that the error reading is common he suggest de soldering and cleaning the circuit board then re solder and seal with lacquer. Not sure if this will work in your case but I did notice the circuit board was a bit dirty in your video he said its the vibration that loosens the solder joints.
Good Luck>> Neil from South Australia
Good project 👍good restoration 👍👍👍👏👏👏
Кошмар Кошмар thank you 😊😊
Good to know I can buy my Bridgeport in almost any condition and revive it.... someday
Good stuff
That camera men!!! Makes me dizzy. Great job and already suscribed, this channel Is great
Rebuild or just deep clean? I’m saying a cleaning.
Yeah, I stopped it once I saw the man bun
@@markman63 guess you have never been to scandinavia
@@markman63 Ya Ikr only assholes don't want there hair to get caught in power tools
Could be bad wire in the DRO harness, and you just got lucky, or perhaps old cap on one of the boards, overall nice job, would get some felt pads, purge all the lines of any grease(with way oil), can even add an auto oiler at some point...and they also have air chucks for the collets, and motor drivers to set the speed :) lots of optional upgrades you could do, if your chasing zeros as well -- but first step is proper maintenance and finding how precise it is
I have a very similar jhead Bridgeport. I don't have the fancy electronics though. Only thing electric is the motor and off and on button. Very handy even for a novice like me.
Awesome work with that really cool machine, now i'a jealous ;-))
واو
Great job kiddo!
Have you had to get any broken parts?
I saw the squeegee trick!
Are there any big gouges?
Can they be welded and ground off smooth?
Once cleaned, the paint looks like it just came out of the factory !
If you are using soapy washer for cleaning, spray with a light coat of Fluid Film when you are done to prevent flash rusting.
Just found you channel today! This was a great video, but the shaky selfie-stick camera was making me nauseous at times. No worries, I just listened to those parts. Really nice mill! I am looking forward to spending more time here. Thanks!
Randy Novick thank you :) sorry about the shaky footage, I'll work on that ;) glad you liked the video!
I hope to be able to do this someday!
Looks exactly like mine.
How much do they run$$$. Apx... I'm interested in buying my.own Mill and a lathe too.. because I just started Machinist College six weeks ago and I'm learning alot.
It's a 7 month program five days a week.. we end up with college credit for Machine technology and engineering credits...
Well Done Bud!!
Nice job man. Well done.
poligon333 thanks man :)
good job
very nice, but more of a deep clean------a :restore: to me-is complete breakdown ,clean,re-assemble. but a very nice job none-the-less.
