Pete, as usual you find the interesting stuff. I watched the video for the idea but found myself watching the entire thing for the simple fact the guys is very interesting and has a pile of cool equipment.

Re: Boring a Bearing Race

I have more questions than answers, but run the lathe at the highest spindle speed possible.

Re: 1911 Project

I've got sears working the way I want, so now it's time to get hammers sorted out.

Re: How can this be?

Mine is actually adjustable with two bolts similar to the table stop arrangement on a surface grinder as the V ways do not extend under the headstock. A horizontal adjusting bolt on each side of a fixed vertical pin. The headstock must be set down on a pivot point like the work head of a universal g...

Re: My band saw broke!!

Thanks, Harold!

It was an interesting project that gave me the opportunity to do a few things I haven't done in a while. I can't say that I have ever cut a woodruff key seat though.

About a half a day' worth of work spread out over a week.

Re: How can this be?

Also, I thought I'd check the parallelism of the tailstock to the head stock and I was shocked! The front disk was .015" smaller than the back. (See pic) Not sure I understand that, as they are side by side. Is the headstock or tailstock end smaller? I ask because there is a much greater chance of ...

Woodruff keyway cut. Didn't want it to move so it's blocked with a 1-2-3 block at each end.

Re: My band saw broke!!

First keyway cut for a 5/16" square key. The TIR was 0.0000" before the cut at the center of the shaft between centers, and 0.0000" after the cut using a B&S .0001" DTI. (I grind with the drive end center "dead", not rotating) DSC03763.JPG The other keyway is a woodruff key at the opposite end, so I...

Hmmm. I'm wondering why you didn't cut the keyways before grinding. They're known to release internal stress, causing the shaft to distort.
Actually, I never gave it a thought until now! :oops:

I'll watch it and see how it reacts.

Thanks!!

Re: Suggestions for flywheel machining setup

Thanks.

What if you used a floating bushing?

I fit 1.350" pins with .0005 pin to bushing and .0005 bushing to rod.

Depends on how your rod ID was finished though.

Re: My band saw broke!!

Everything ground but the threads. Just need a couple of keyways cut now.

The worm wheel just slides on but will sty in place. Gotta love grinding!
