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...

Re: CME 4-jaw chuck

I like 4 jaw chucks that have T-slots between the jaws. This allows for some fixtures if needed. 4 jaw chucks that have 2 piece jaws where the tops can be unbolted and turned around are nice. You can remove the solid jaws and make your own special jaws. I needed some jaws that were longer than the s...

Re: How easy to add USB to a 1993 hass lathe?

The machine has parallel ports which I think are the D25. I would have to check to be sure. We couldn't get the USB to serial port with a parallel adapter to work. Also a working 3 1/2" drive from a computer didn't work for some reason. Anyway today they got a USB emulator to replace the floppy driv...

Re: Diagnosing a Milling Machie problem

My guess is that your gripping problems stem from anti rotation pin is missing, the anti rotation pin would keep the collet from spinning insuring that the draw bar will draw the collet tight around the shank of your endmill. Is that pin accessible from the outside of the spindle ? on both my 5C co...

Re: Good practice question

No-one has mentioned follower rests, yet. I don't have one so I can't say yay or nay. I'm in the opposite situation: I have a follower, but no steady. So maybe in a situation like the one that prompted my question, a follower could be sufficient? I have bought a roller steady rest off Ebay an made ...

How easy to add USB to a 1993 hass lathe?

How easy is it to add USB port to a 1993 HAAS lathe? It has a 3 1/2" drive now which isn't working.

Sure, $1200 to adorn the tail stock of a $1200 lathe that has been "turning" out good parts with its original center.
I used the pictures to show what type of center I was talking about. You can get all 3 different styles for about $150. on ebay with a #4 taper.

Re: all-thread studs for clamping

I can't imagine tightening anything to the mill table so tightly as to threaten even the worst threaded rod. I have seen table slots broken from over tightening. Including table slots that take a 7/8" stud. The big reason for me on the of B7 is they last so much longer than the ones you get in the ...

Re: Good practice question

I like these tracer point/extended point live centers. https://www.travers.com/revolving-tailstock-center/p/63-301-787/ Of course the old standard live center is really nice to, but often times to large to get the tool close on smaller diameters. https://www.travers.com/revolving-tailstock-center/p/...

Wait, I thought you were supposed to hold the tip in your left hand and the round part in your right?? Or is that just in the western hemisphere? :)
I have always done it like the video, only I use a 6" wide belt sander on large drills. I prefer an 8" grinder though for most drills.
