Great job. I can appreciate the time and effort you have put into this project, having recently completed a lengthy restoration project of my own.I love it when somebody saves a piece old iron and puts it back to work.
Here are some pics of my restoration of a 100 year old Becker Mill that was being loaded on to a truck for the scrap yard before my cousin and I rescued it.








Ready to be assembled!!

At at a guess- 150 hours+.

I had to take it down to the last nut and bolt and to the bare castings and then bondo and sand everything smooth ,as the castings under the mystery sludge( where there was any) were very rough.Then I had to design and build a drive system for it( it was originally driven by overhead shaft), build several missing parts with a couple of grainy pictures as reference and repair the broken overarm clamp.
I have to say though that this was one of the most satisfying projects I have ever undertaken and I have an amazing tool to show for it.This beast will easily hog off .100" at a wack from a 4" wide steel work piece and hold tolerance to within .001" across the whole travel of the table.They sure built stuff to last.
I hope your project goes well, and post progress pics when you can.

I like the Bp round ram. My first mill was an old round ram.

I must say, though, I hate the color! That is just me. I prefer the original machine tool colors.

Keep up the rest of the good work but I will never allow you to paint my home:D

I hope you didn't take my comment about the color in a negative way! I have a section of my shop with blue but all are welder and the racks they reside on/in.

You are doing a good job with the rebuild. Can I ask, how did you clean the components? Everything is really clean and sorted. Make sure that when you go to reassemble, that you use the correct lube depending on location.

If you have any questions, there is a fella that goes by Sidecar580 over on the PM website. He rebuilds Bridgeports all the time and is very good at what he does. He was very helpful when I rebuilt the head in my variable speed Bp.

Keep up the good work and stay with it.

I vote for a polish on the aluminum housing!
On another note, if you ever have a problem with your return quill spring lock, you can put a small neodymian magnet on the large clocking nut close to the quill lock. Works so much better than the original spring! ;-)

Another mod I did on mine was I took the quill handle off and put on a wheel about the size of a small sterring wheel. It allows much finer control over the quill as there is no slop in it.

When I redid my J Head, I polished the upper belt case (whatever its called) it wasnt as tough as I thought. Nice job to do and have a couple beers and relax......haha. Machine looks great! I did the traditional gray (I used Rustoleum Machine Gray I think its called, brush and roller) You learn alot about your machine and how it works by taking it apart like you did, plus find any problems.

got some more picture updates of the mill project. just so everyone knows im only 25 and money is a limiting factor in how fast i can put this thing together. but i think thats a issue with everyone and there projects for the most part. just gotta make or rebuild each piece. it would be nice to just go buy all new parts. but thats just not possiable. iill get pictures posted up in the next hour or so.
