Re: Oh Foo!

Replacement Harley and Indian crankshaft bearing rollers used to be furnished in bulk, graduated in 0.0002" increments. I spilled a set of them "ONCE". Never again!

Re: Maximat Compact 10" MQ-3100 Lathe Build

Years ago when it contained phosphates, we used to use boiling water and Tide to clean all old engine and carburetor parts in a motorcycle shop. It is surprising how much heat helps in the cleaning process. If your motor runs normally in the forward direction and hums in the reverse direction, that ...

Re: How Many Flutes for Wood?

I have never used it but I have an air driven high speed spindle that will fit into a collet or end mill holder. It seems like it would be fairly easy to make something similar.

Re: Rotary valved engines

Of course there are frictional losses and the springs don't return 100 percent of energy but I have noticed that camshafts with many lobes tend to be pretty easy to rotate by hand. So the springs do seem to return energy as they extend.

Re: Here Goes

Nice looking shop. I wish mine had visible floor space like that.

Re: camshaft layout

Since there haven't been any replies by someone who really knows the answer to your question, I will offer what might be a little help. It seems to me that the camshaft order has to be the same as the crankshaft. If #1 inlet cam is at 0 degrees, #5 should be at 60 degrees, opposite to the direction ...

Re: Speed control on whole house fan

I am pretty sure those speed controls are only suitable for shaded pole motors and these are used only on direct drive fans. If your fan has a split phase or capacitor start it would likely not be usable.

Re: Lathe tool holders?

You can use either type of toolholder with HSS bits if you grind the bits for a rake suited to the work. 20 degrees seems like a steep rake, more suitable for aluminum. I think some toolholders are made with about 7 degrees of rake for using HSS on ferrous work.

Re: How hot does your electric motor get when making heavy c

Modern motors often get too hot to hold without damage. Check the rated Full Load Amperes (FLA) of the motor against your breakers as the wiring and breakers should be rated for at least that much current.

Re: Cutting wood screw threads?

I would think a suitable tool and an improvised taper attachment along with manual rotation of the spindle would do it. A simple angle iron clamped to the bed at the desired angle and some sort of cross slide stop bearing against it could be used to make the taper by manually feeding to keep the sto...

Re: Troubleshooting electric motor noise

Check the rotor for wasp nests or other debris. Also try it without the pulley as it may not be balanced.

Re: Trouble removing the saddle from a Power-Kraft lathe

If I understand your post, you have moved the cross slide (not the saddle) back until it has unscrewed from the feed screw. If so, just pull it back toward the front while turning the handle CCW until it threads back on. Don't force it against the screw threads but be sure it slides fairly easily.
