Hands down, this has to be the BEST video on UA-cam that shows what this process is really like from the "user" perspective. I'll be tackling this job myself, hopefully fairly soon, as it's getting to the point where I really dread even turning on my mill due to the racket.
I have the same mill at work that’s making the same noise just not as severe and a little more knocking sounds and this was great to see what all the disassembly entails, thank you, also thanks for showing that timing app, I was gonna use a gun but that is nice n easy, great job my friend!! And again thank you!
I wish I saw your video before I rebuilt my mill, it would have saved me a ton of time. I could not find any information on how to adjust the variable speed plate so I did the same thing you did with a tachometer. All of the other videos say, "do not remove the bolt".
Like a dumb ass, I had the motor and head vertical and stood on two ladders and the table. When I finished, I realized I should have rotated the head 90 degrees so I could reach the parts better. Oh well, live and learn.
I hope you grabbed it! Once you own one, you'll wonder how you lived without one. I paid 100$ for mine, with a Kurt vise!! I've used it for over 20 years now, only now does it seem like I need to do some work on it. They are fairly bulletproof. You can find them for 1000, 1200, 1500$ pretty often, people often don't have the room for them or the power to run them. If you buy a 3 phase, a static convertor is only about 60$, easy stuff.
Great video, I have just purchased a Bridgeport series 1 2HP like yours, the bearings had all been done and a new belt fitted but the shims were never replaced, so it is a little bit noisy, although fairly smooth. Now I can attack the job of replacing the shims with confidence. Once I find them in the UK
You and I would be the best of friends. From the Natty Ice, to your shop, to the tools and parts everywhere, the Bridgeport, lathe etc, we are very much alike 😂 H & W seems to be on the high end, but they do have everything and make some great How - To videos. I think my motor died tonight, I'm not happy; but the auto feed hasn't worked for aabout a year so I guess it's time to fix it all at once. I use my mill 75% of the time I'm in my shop so I need it.
Speed Selector makes variable speed pulleys that replace the Reeves, Hi-Lo, TB Woods and Lovejoy pulleys that went out of business or got bought. Most of the pulleys are in stock or Speed Selector will custom make if needed. They have an actual engineering department who were very helpful.
Ok, wow, I REALLY need to stop procrastinating and do this myself. Mine is an unholy racket at anything under 1000 RPM. hearing the difference this made for you just seals it.
Its worth doing. A couple hundred dollars and a few hours but every time I turn the machine on it makes me happy to hear it purring away like its supposed to
@@spankranchgarage Yeah, I’ll be calling H&W right after the holidays. It’s gotten so that every time i turn mine on it’s more of a “wince and pucker” on my end... hahaha
I think you might want to try to refloat the head on your Bridgeport. I noticed some rubbing sounds when you were getting up there in RPM, similar to the ones I ran into when refloating the head on my mill. I made a quick video of it just to demonstrate what the head is supposed to sound like. I didn't have any references while working on it so I wanted to share what I learned.
I checked out your video. Your machine looks great! What did you mean by balancing? Like a real dynamic balance of the components? And yes I will play with this head more. I get a certain noise only when the head is cold. It goes away once it warms up and isnt existant in the summer (My shop has no AC)
@@spankranchgarage Okay that's good to hear. Yeah, all of the components in the head from the bearing cap on top to the spindle are aligned and not causing vibrations from being off-centered. It took a lot of attempts to get my machine balanced. It's very finicky because you are trying to balance both a spindle and a transmission all at the same time. So any little bit of runout will cause some kind of noise and vibration.
Great video man, was wondering if you measured the spindle runout after the rebuild? Been reading that after replacing the bearings you should regrind the spindle taper. Been wondering if a regrind is necessary or if the spindle will still be in spec without a regrind after replacing the bearings.
I didn't. I didn't change my spindle bearings, I only rebuilt the top end in this video as my bearings are still nice and quiet. For the work I do, some spindle runout isnt too impactful. But I have seen some interesting videos of how people are grinding their spindles. Looks very doable in the home shop
@@spankranchgarage Thank you for the reply. I'll have to check out some of those spindle regrind setups. I definitely need to rebuild my top end and you made it look easy/did a nice job. Do you happen to have a tenths indicator to measure your runout? Nervous about rebuilding mine and curious if your rebuild effected the runout even though it was a top end build only.
I would suspect it’s a back gear or back gear belt issue. You can see those parts in this video. Unfortunately you have to tear it down pretty far to get to these
For the main column casting I used a wire brush on a grinder. There is paint and body filler on these castings and its very time consuming and messy to remove. For the head components, the OEM paint was in much better shape. I just touched up spots that were flaking with sandpaper then painted over the OEM paint.

The quill bearings are really easy to change without much disassembly. They are sold in a set, and are matched. This was a great video...Thank you.

Thank you! Its not too bad once you get into it.

No problem good luck!
Dominators ftw! And ftr, I was excited to witness her all gussied up. She's a right-proper beauty now.
Good video, glad it is running well for you. I agree that H&W is super helpful and I used them for all my parts when I rebuilt my Bridgeport.
I’m glad this video popped up. Thanks man with details.

Sounds like you got it all figured out one way or another. Great to hear.
Like a dumb ass, I had the motor and head vertical and stood on two ladders and the table. When I finished, I realized I should have rotated the head 90 degrees so I could reach the parts better. Oh well, live and learn.
Good job, extended the life of a very nice old machine.
I need another 30 years out of this one!
There's a $600 Bridgeport for sale near me that has a squealing noise coming from the top. Awfully tempting after watching your video.

Good luck! Its a very rewarding job and every old bridgeport deserves it!
If you've never done one before that was great. Well done 👏
Super video, glad I found this! I had planned to go through my motor drive in the next few weeks and this is a huge help. Thanks for posting!
Good luck!

Cheap beer and mass chaos!! Whatever gets it done
Gonna have to get that app! Great video
Wow, your dog looks like the twin of Homeless from Cutting Edge Engineering!
We always joke that she would be the perfect girlfriend for Homeless!
Tengo Bridgesport 1,5 hp variable , cual es la correa que lleva , gracias !!!
Haga un pedido en machinerypartsdepot.com. Ellos saben lo que es correa. Buena suerte

Great video . Now I think I can get into my mill head with some confidence . What's the tach app called ?
It’s called VideoTachometer. It’s free to use with a resolution of 10rpm. If you want 1rpm resolution you will have to pay
@@spankranchgarage Thanks for the info
@@spankranchgarage : "Video Tachometer": Thank you !!!

Don't worry mate. This exited me too. Cheers
This video brings back memories. Fixed one myself years ago.
Where exactly do you live in Pa ??? We just might be neighbors.
that app is awesome
Nice job on the rebuild. What is that camera app for RPM?
Thanks. The App is called “videotachometer”
@@spankranchgarage Got it. unfortunately its iOS only and no android version. installed on wife's phone.
what app was that you used to measure RPM?
Look for "VideoTachometer" in the app store
apple or google?@@spankranchgarage
My Bridgeport is noisy on low speed but runs quite on high speed. Anyone know why this would be?
I would suspect it’s a back gear or back gear belt issue. You can see those parts in this video. Unfortunately you have to tear it down pretty far to get to these
What app is that ?
It was called "videotachometer" on iOS
👍
theres a natty lite stuck inside there I just know it
I feel like I missed an opportunity here

awesome work man. What did you use to take the old paint off? Cant ever find a good answer to that, was it time consuming to do it? thanks.
For the main column casting I used a wire brush on a grinder. There is paint and body filler on these castings and its very time consuming and messy to remove. For the head components, the OEM paint was in much better shape. I just touched up spots that were flaking with sandpaper then painted over the OEM paint.
