This 1977, series1 - 2J Head BRIDGEPORT mill came to me with some problems that i thought i can handle it. I'll finish it completetly in 2 videos. Hope you enjoy it and thanks so much for watching!
You first built a gantry crane, then began fixing a very heavy machine. There is a reason sealed bearing are used. They seal in lubrication and seal out junk. As lway, you improve what you fix. You tackle jobs which would challenge machinists twice your age, with far more resources. It always a pleasure seeing you restore things others would not touch.
A joy to watch it come back to life....The driving dog skim and file up, Kudos for doing that ball aching bit....I worked a Bridgeport for a year or two after I Left the Ordnance Factory where I did my Apprenticeship...Worked a Mill for 15 years making a living, ended up designing Laser Cutting machines, retired now....I just have a small Myford Lathe at home to play on now.
I like that. "At least I will learn something." Great outlook. I can't even imagine being that brave to tear apart such a complex machine and have the confidence to put it all back together again. Congrats on the BEAUTIFUL machine. And thank you very much for uploading. It was super entertaining!
An excellent video, so good to fast forward the tedious bits and get straight to the point. I have a 48 inch Ostmac that seems identical in almost everything you presented here and it is a bit chattery when fly cutting and your vid has pinpointed the source for me and given me the confidence to do a rebuild as you have so very well done here, I really did enjoy watching you do this and I do like watching clean work, to me it shows the respect a man has for the craftsmanship of others, especially a Bridgeport
I appreciate so much yours videos... I don't want to imagine how time you had spent on yours projects. I start buying a milling in this period and this video is a starting point for me. Incredible work💪.
Nothing wrong with being a thinking true machinist and mechanic. Guys that can do that are in short supply around the world. Great job....Dave

David Richards thank you, sir. Im still mess up with the table dovetail. I wish i have enough tools to fix it the right way but so hard to find tools here, expecialy someone amateur and poor like me.
Excellent work Cà Lem! Quick thought, you should run some black enamel paint on the laser engraving to make it easier to read, plus it would make it look that much better.
It's nice to see the pride taken and the excellent workmanship. Bravo to a job well done. I was especially impressed with the hand filing. That's detailed work and the results were mind blowing.
Well done Sir! There are a lot of unique challenges going through those heads and I commend you for the solutions you created and the diligence to complete the project.
very interesting video, im in the process of restoring a taiwanese copy of a bridgeport which is larger and heavier and this has been very challenging but seeing your video has inspired me to continue, 7 months so far and getting close to the end, good luck and look forward to the next part of your restoration
Thanks for sharing, great job on the rebuild. And the oil change seems needed . I too dont like the oil dripping all the time. I can only think of one or two reasons for having it . Guess we will find out how it works out with yours. Good job
Seriously amazing, mate. A lot of work and time!!! I also have got a super worn out Bridgeport standing like a stone at the corner of my warehouse. Cannot take an effort to fix it.... Well done, mate
Very nice work. The variable speed Bridgeport’s are notorious for being noisy and vibrating. I have a generic variable speed in the garage. It’s not very smooth. All the old timers here in the Midwest ( Ohio, Pa, NY, Mich) like the step pulley heads, especially the mills with the flat “pancake” motors. They are easier to move in to low ceiling garages. Keep up the nice work, you do professional rebuilds !
A brilliant job - you are a true craftsman. I am having a Bridgeport delivered on Monday - no idea what it will be like. I bought it cheap. It looks good but no idea of wear. I don't know if I could ever find the time to do a full restoration but I would love to do it. Your videos are a great help. Thank You!

codprawn thank you brother! I did alot of mistakes but finally learned some important things. Pls fell free to ask me anything. I could help you some.
@ Thank you! When I get my Bridgeport I will definitely ask you for help. Have you seen Clickspring - This Old Tony and Doubleboost on RU-vid. They also make great videos!
When you take sealed bearings , think about taking out the seal at one side. So you can put the bearing with the open side looking inside a casing and with the closed side looking outside. That way the oil from the inner side still reaches the bearing , but the outer seal prevents the mess at the outer side.
WOW!! You consider this NOT a full restoration? Buddy .. my hat is off to your skill and ingenuity .. good luck with it! I'm excited to see the next part!

thanks,buddy. me too, cant wait to see how it running.
As I look at this marvel of engineering I am wondering how the heck did a person come up with this machine? It's just crazy the amount gears and apparatuses this mill has.
Take pictures, many pictures of the disasembly process. Put parts in different bins and or zip lock bags and put a label on each and every one of them and put a number on each and everyone of them. The first part is number one and the last part is...?
That was a huge risk turning a mm off the spline but you did it. Hand clap. As far as the delrin bushings, i would have just bought them off ebay companys have them new in bow for cheap. But i envy you, i dream i never persude even though i ran many bridgeports over 20 years.
Great job Ca Lem! If you make friends with people on machinist websites, I'm sure someone would be willing to send you parts that may be hard to find in your area.
Great Job -- 4 thumbs up -- that means two thumbs -- twice . Sweet, Sweet - Rebuild -- when I grow up I wanna be just like you. I'm 76 years old -- I'd better hurry up
Hello, excuse me I changed ball bearings and wedges I did the full service but when I turned it on I notice excess noise in the part where the speed between the bands is adjusted do you know how I can make that adjustment to eliminate that noise ? Thank you and excellent video
Bad practice putting your finger in a rotating hole, it can twist your finger off in a heart beat! Sooner or later you will have a bad day and be inattentive, it is then bad habits will bite you. Use a stick or tool. Nice numbers in the speed dial! How did you make those? Great find on that Bridgeport. Table looks pristine!
It did happen to one of the machinist I know a few months back. He was checking the inside diameter of a cast iron shaft when it was spinning with an inside caliper. The caliper caught a burr in the casting and twisted his thumb. His thumb was badly mangled but did survive the mess. So take care.
Oh, my goodness! My stomach actually did flips when I saw you put your finger inside that part.. A few years back. I came close to loseing my little finger on my right hand while deburring the bore of a part on the lathe...My advice? Don't ever do what I did!
Cà Lem, USA has few residences with 3-phase power, there is real need with hobby/home machinists and woodworkers for single phase to 3-phase converters vfd, to use with commercial machinery and to be able to change frequency and rpm with the vfd. VFDs are also big money makers for industry since they can save power by turning down the speed of fixed rpm equipment when full speed is not needed. Air conditioning, air compressors, and fans are some examples. Due to commercial use, non-Chinese VFDs are way too expensive here, exceeding the price of new motors. Have you ever tried making a VFD?

thers are alot of second hand stuff u can buy with really good deal in US. not like here everything expensive even used stuff.
It does not hurt to install bearings over small low spots, they will bridge over, but it DOES hurt to install over high spots, since they will cause the race to warp out of round. No harm in skimming off half thousandth inch or less, I guess. I’m not a Bridgeport expert, though. Where did you learn machine work? Your friend?
I love the work you have done on this. I have a question for you - I have just bought a Bridgeport with the same head as yours. I am lucky. It runs very very smoothly BUT I have a problem. The speed adjuster is very easy to turn when you are going faster - but when you turn it the other way to slow down it is harder to turn. Is this normal? Any idea why it happens? Easy to go fast - harder to slow down.

codprawn its normal, man. Check out how variable speed pulley works. When you change the speed actually you are changing the distace of 2 flanges (vari-disk). Those flanges are kept closed by spring pressure and of course its harder to press the spring than return it to the free length.
Nice work. I like that. Where do you have this milling machine ? (I believe that the history of this machine could be interesting as same like the restoration... If you have that ;-) )

actually this machine came from Japan. Bridgeport made for amada (a machinery company in Japan).
