Re: Wheel turning method

How critical is it that the tread be turned? What is the anticipated use for the wheels? What about just boring the wheels and calling them good.

Re: Delta Milwaukee Toolmaker Grinder owners

I was able to freehand grind the threading bit I used. Use the threaded rod as a thread guage and grind slowly until the bit will not quite fully bottom in the groove. Slightly oversize will not hurt as the thread and nut are loaded in one direction only. You could also make the bit a shade narrow a...

Re: Wheel turning method

By all means rebore a centered hole first.

Turning that diameter with a 1 1/4" stud as a driver will mean very light cuts - a real lesson in frustration.

Can you 1) add a keyway, or 2) add a driving pin further out?

off topic

The discussion of the M D (Delta Milwaukee) in General Discussion reminds me of the MD-80 (McDonnel Douglas) aircraft which used a similar screw in the tail surface control surfaces. At least one nut failed the same way and planted a plane load of passengers off of the CA cost about 30 years ago. In...

Re: Delta Milwaukee Toolmaker Grinder owners

I bought a six ft piece of rod, used less than two ft. You can have a piece for shipping costs.

Re: Delta Milwaukee Toolmaker Grinder owners

So, I just saved a bundle! I managed the repairs as simply as possible. The raising screw has 4" of full diameter, 3/4", unthreaded shaft, there is a key way and two taper pins retaining shaft collars, in that area. I cut off the unthreaded portion, put it in the lathe, and drilled and reamed a 7/16...

Re: Show us your lathe!

Like ever thing, depends on what you want to do'; and then add a generous allowance! I do my limited wood turning on my 13" swing metal lathe. Mt brother, who is a serious wood turner, has several wood lathes. A wide speed range, and the ability to turn on the outside of the head stock are desirable...

Re: Single Point Threading 101

Yes, If you are cutting metric threads with an inch lead screw or cutting inch threads with a metric lead screw, there is a difficulty in locating the correct place to reengage. I have read of a procedure for determining the correct point, but do not remember it. I was cutting inch with inch.

Re: Delta Milwaukee Toolmaker Grinder owners

Got the same problem with my Delta Toolmaker. I noticed the acme threads were more saw toothed in shape than acme. The correct size acme threaded rod is available and I have a piece ready to go. Might have even procured the tap via ebay. One of those projects I need to dust off before the failure ha...

Re: Single Point Threading 101

Please explain the limitation.

I have cut threads using a boring bar and running reverse, without regard to thread type, almost always standard V, or pitch. No problems that I was aware of.

Re: Restoring bench grinder

Might consider a little epoxy along with the clamp, to fill in any unevenness or voids.
