This style of faceplate in use

The pump center is used to center a feature on the work to the axis of the lathe.   The rest is just clamps.

Making some accessories for the Levin, and a #12-40 ( 0.217" diameter x 40 threads per in )  Left thread and right hand is required.     #12-40 right hand taps are readily available, but not so the Left hand one...so    I made one!

I found this method at Practical Machinist, and I want to say it works awesome!

See pictures below

Hi Dave,
 Now that could be very handy! Can you give us a quick how to? It looks like only the front has full threads on it?

Cheers Kerrin
Get excited and make something!

Kerrin....that's an artifact of the photo.   The threads go full length, and the tap has 4 flats ground on it at the business end.    You cut the thread on the tap, harden it, then grind 4 flats at about a 20 degree angle.   Now I milled 4 flat before I hardened it, but I still touched off on the grinding wheel on those flat faces after heat treat...the angle is not critical at all, but having the small end of the tap go below the root diameter is.   This tap needed guidance to get started, so I started it in the drill chuck of the lathe     It cuts amazingly well!.    I made the tap 0.219 diameter...like the commercial right hand tap I have.   I then cut the male thread to 0.218 diameter.     It has a very nice fit, with no shake.

Make sure you wrap the tool with iron wire, and either dip in silver solder flux, or liquid soap.    This will keep the tool from burning during heat treat.

I used 0-1 tool steel.   Silver steel to you blokes over there.

Brighten the tool up, polish the flats, and draw to brown.    That's it!

Dave

Just picked up this Countershaft.    I believe it was from a George Adams brand lathe, but I got it, because it's really compact, and will go in the box easily.

It's pretty crusty!....it spent a lot of time in a barn somewhere, but it's all there, and it works well.   I was able to take it all apart and give it a good acetone soak, and a good scrub.   I also put a coat of new black paint on the painted bits.    The nickel plating is coming off the rest of it so I think I'll just call that patina.     Anyway....once together, I'll post an after photo.

Picked up some more collets.   I got some used Levins, but I also got some Sherline WW collets as well    They seem fine.  I think I'm good now on collets

I also have a Starrett pin chuck coming that I'm going to use as a drill runner chuck.
