That looks like a good idea already. The only other things I can think of would be semi-circular grooves or troughs in a thick piece of wood or shallow round holes in a piece of wood.

Although made for turning armature commutators, that lathe will do general lathe work with the exception of threading. I am not sure but it looks like the power feed disconnect may be the long collar near the left end of the leadscrew. If that chuck in the tailstock is the Jacobs armature chuck with...

I can't tell much else but the taper attachment seems to be missing the block which slides along the bar. In one type of attachment this block is connected to the cross slide by a slotted arm and lock bolt which provides coarse adjustment of the slide position. This type requires a separate compound...

My Christmas will certainly be Merry and I hope all others will be too. (Including Scrooges and Grinches. )

I got the idea that you may be concerned about manual fine feeding toward the chuck for facing type work. It is not very convenient but you can lock the half-nuts onto the leadscrew and use the leadscrew for fine feeding. If it has an accessible gear on it, you can even calculate how much feed you g...

Actually you would only have to insulate the wiper motor from the chassis if one of the power supply terminals is permanently connected to the chassis also. Otherwise the power supply leads could be easily reversed (ground either negative or positive). I would think a dedicated power supply would be...

Looks good!

I don't know about M heads but some J heads certainly came with sealed spindle bearings.

I agree with Glenn on the hammer and punch. If you can jar the bolt lengthwise hard enough it nearly always loosens without damage. For Allen type fasteners I prefer a steel punch down in the socket. I like to hit it really hard with a heavy hammer like I am trying to drive it out. The air hammer of...

Dual fuel, diesel and natural gas, engines have been used in power plants for at least 50 years. The Safeguard Anti-Missile system used several Cooper Bessemer LSV-16 engines so equipped. They were approximately 5000 HP at 360 RPM. They started on diesel, then a control started injecting gas into th...

I have no idea what they are but they look uniform in thickness and all seem to have the notch so I don't think they are made from knife blades. The notch seems to be a functional feature to me. It kinda looks like there may have been some sort of writing on them.

Some, if not most, torch leaks are after the valves so they leak only when the valves are open.
