Re: Beveling an edge on a piece of plate

This is a sine plate. https://www.mscdirect.com/browse/tnpla/08020109 For what you are doing, I wouldn't spend that much for one. A crude approximation that is made with a little care should get you an adjustable version for rough projects. If this is the only thing you need it for, Just weld a coup...

Re: Annealing E52100 steel ?

Anyone need some 5/16" dia. Low Carbon Steel balls ? I have 242 left ! Funny how that works! I order hardware like that all the time. $5 for 3 or $6 for 1000. Well, I might someday need more than 3, so sure. Actually I just ordered some metric snap rings from Grainger because there's no shipping ch...

Re: Sound Bend 9" lathe, MT-3 to ER-40?

Make a ring with set screws in it to run in a steady rest. Then chuck the other end and drill your centers. Actually, I think I watched a video of somebody else who did that recently.

Re: Starrett combination squares

I have several. Some get used often, like my little 6" Empire. Others get used when I need something longer, or when I need a second square. Lots of times I'll use a couple of them as "large calipers". Then there are the protractors and center finders.

I was thinking that most have flats ground on the shank that you could sink set screws into.

Re: Annular cutters

John Saunders did a tour of a shop where they had trepanning tools for large holes. These were way bigger than your example, but all of these tools (trepanning tools, hole saws, annular cutters) accomplish the same thing. Don't see why it wouldn't work as long as you can make sure it's centered up. ...

Re: Repairing Bridgeport servo power feed

You've probably already figured this out, but the bottom gear appears to come off the same way as on the 140. It may be snug, though. I think I had to work at it a little bit after I got the nut off. You can see in the assembly diagram that parts 88-92 are an assembly. This doesn't appear to have ch...

Re: CCMT recycle face mills

Shars also sells that kind of face mill. It is rather inexpensive. Another option is a lathe toolholder that hols them "sideways". You can get lead angle turning tools or chamferingg tools. Again Shars sells them. I've searched the Shars site and don't see a facemill that accepts any CC** insert. D...

Re: Sound Bend 9" lathe, MT-3 to ER-40?

My main reason for using collets is for speed, not accuracy. If I spent big $$$ on collets that had less runout, I might trust them more, but as it is, I'm not spending that kind of $$$ and I don't trust the ones I have now.

Re: Sound Bend 9" lathe, MT-3 to ER-40?

Ebay has a bunch of them. I use ER-25 collets in straight shank holders that I hold in a 4-jaw. I can put that holder in a vise, also, though I use collet blocks when I can. Depending on the quality of collets you use, you may get better runout that way than depending on the spindle, adapter, and co...

Re: Repairing Bridgeport servo power feed

If it's really cloned off of the Servo, once the four screws are out, you can remove the lever then take the name plate off of the front. It had adhesive on mine that didn't do much, but I still took it off. Then just persuade it apart. The gear doesn't have to come off, depending on how your's is a...
