Re: Anyone familiar with Supermax Lathes

They seem to sell what ever they get a good buy on. With that being said I have seen the same lathes with the "JET" and "Birmingham". If I remember correctly the ones that I have seen were made in Twain? I don't know which one exactly that you are asking about?

Re: Tramming range

I usually tram into the width of the table. If the table is 9" wide then I ream to just under a 9" circle. With in .001 inch is most likely way better then you need to be.

Re: Uneven cut

I would check to see if the pattern had the same spacing as the pitch of the screw in the Y axis. If it does? You may have a bent screw on the Y axis? Wouldn't hurt to check the gib either.

Re: No good deed goes unpunished.

What kind of mill is it and what type of power feed unit is on the X-axis? Many of the Bridgeport clones use the Servo or similar power feed units. They have a plastic gear that is usually the victim when table stops moving, yet the motor keeps running. Nyle The plastic gear has been my experience ...

Re: New guy with a new used mill lots of questions.

Lets start... I like to work with metal and expanding my machine collection. I picked up a heavy 10 South Bend lathe. Now I picked up a Burke Millrite MVN mill. It came with some stuff. It was an estate and the guy who owned it passed away. His son was selling everything and told me to dig through ...

Re: Hi, I have a few items I’m trying to identify.

Your vise is usually used on tool and cutter grinders. I have used them to grind special lathe bits. They are not built to be rigid because you don't need to be all that rigid if you are just kissing the material with a grinding wheel. I bought a new one off ebay years ago.

Re: Bridgeport as a drill press

OK, thanks guys. Oh, and if anyone wants to buy this Bridgeport, contact me via PM. It's located near Bridgeport (yes, it hasn't traveled very far from the place of its birth). We are still working on prices (I'm helping to liquidate a machine shop). Steve If you are helping to sell a machine shop,...

Re: Capabilities of a 12" lathe

Depends on which 12 lathe you have? If it fit in the lathe I would try it. If the center is hollow you may be able to give additional support with the tail stock center if needed?

If not, then a rotary table on the mill might be the place?

Re: Dubious Restoration

Looks to me as if it could have been restored, but it appears that he removed *all* of the rust from the ways. The fact that he doesn't bother to show us that step speaks volumes. He clearly considers it unimportant compared to the painting. Not showing how he cleaned the ways made me wonder as wel...

Re: Piston or Wedge

Aside from using an indexing square holder, my greatest experience is with the KDK post, which is also a wedge design. I was quite impressed with them, and used several sizes. One of them was on a 42" Dean Smith Grace lathe. Heavy holders, not fun to change, but up to the task. H Harold its my unde...
