If there wass any confusion from my post I will not be welding ON the SS. Maybe, possibly some light surface grinding, but unlikely. Horz boring would be done on the metal lathe - as it is so designed.

We want warped wood.

The speed control cam(nylon) is your greatest concern. Keep it happy by not(<<<<<<<<ignore this word
) keeping the small bearing that rides on it cool by proper lubrication.

doc,
I believe, as Dusty points out, that was a mis-type by JPG saying
by not keeping the small bearing that rides on it cool by proper lubrication.
The link in my first post mentions that bearing also and the role it can play in damaging the cam. It's part of the reason I linked that thread. The Speed Control Cam is a weak link in the headstock operation and if Shopsmith still sold Mark VII parts it would likely be added to the 17 most common ordered repair parts.
Do continue to follow that other thread "VII Headstock Overhaul". JPG has added a link in it to his restoration of a Mark VII and information in that link may be useful to you.
Others have commented about additional functions you could use your Mark VII for metal work. The Sanding Disk will work great for metal. One thing I would recommend would be to cover the Way Tubes to protect them when using the Sanding Disk for metal grinding. I have a piece of sheet metal which I curved the ends to wrap partly around the Way Tubes to hold it in place.

I did notice a change in speed after turning on the switch briefly without me turning the knob. Will be looking into that as well as the bearings, belts, and quill shaft.

The speed control knob has a propensity to slip on it's own because of vibration and weakened detent springs.

Hi folks. I decided to go a different way. This looks better than the SS process.

A touch of levity is always good on a Tue afternoon.

Dang it, now I’ve gotta get myself a bigger “hand drill”!
Do you suppose those come in cordless?
