The key is that you have to get your cutters low enough to cut on centre. That Busybee set is "AXA" size but most people use the smaller "0XA" size with a 618. You might possibly be able to make it work with 1/4 inch shank tools as the cutting edge will automatically be at a lower height. The...

Susq does a good job of summarizing the _general_ case for a VFD and I don't disagree. I'll just point out that this thread started out about Keith's _specific_ instance involving a 10ee. The 10ee is a stout lathe and came equipped--in the 1940's--with a drive system that is tough to match...

I could be wrong but I believe the motivation was something like...the lathe came with the DC motor, which included a back gear arrangement, and is capable of good torque through a wide RPM range. He wanted to keep the machine as original as possible but drive it with modern, reliable...

That looks like an RF-25 machine. I believe they usually have a 7.5 X 23 inch table. Weight is typically about 350 pounds v. 500-600 for RF-30 class machines. Looks like the motor has been replaced. Nonetheless, you could almost certainly refurbish it and flip it for a profit. Soak the...

Shaming? No! I'm sure we all support @Mcgyver together with other consenting adults in any of their private activities... with a motorized sewing machine... and Swinger accessories. Right?!? ;) Craig

From Jacobs 1947 catalog: Craig

This style: Very handy for inside measurements. Can also do hole-to-hole measurements (within range). Craig

@gerritv has been preaching about these for the last couple of years (at least). The DotStripe store, it appears, sells major brand name inserts for next to nothing. They obfuscate the manufacturer names a little but it is easy to decipher. Maybe these are production overruns? Maybe these...

Always tempting but I don't think I can make it this time. Craig

New babbitt is still available. For example: https://www.mcmaster.com/products/babbitt/casting-metals-2~/ Craig

I can't find an emoji for 'taking a bow'? Craig (I enjoyed Heinlein's writing years ago but I think grok has passed into the general lexicon now. Right?)

Nope, it switches power too. The scheme is explained in the last section of this video: You need to watch the whole video though. BTW, his 5 conductor/3 conductor wiring schemes are specific to a certain style of rotary drum switch operating a 240 V single phase motor. The approach would...

Thanks for reminding me. The video I watched showed two wiring schemes. One with 5 conductors and the other with just 3. I can follow the 5 conductor scheme but the 3 conductor arrangement seems like magic. It is kind of tagged on at the end of the video. He draws the current path for...

Normally I'd agree about bigger being better but in this case the maximum diameter is also a concern. It would be difficult to modify the drum switch but I'd have to replace the motor junction box. There is no space to enlarge the entrance for the cable. I don't want to get into trying to...

Thank you for checking. What kind of diameter is the overall cable? Craig
