They're almost in line, which is additionally interesting, about as close together as they can get.

Is there anyone on this forum who has actually purchased one of these "Bargains"? I recently scooped up a bunch of Mark VII parts that were spotted here. I think this sort of forum is an important function for this community, connecting people with orphaned machines and parts, offering ad...

At higher speeds there's more push from the sheave to drift the control higher; this can happen on the Mark Vs as well. What keeps the control in place on the VII are the two spring-loaded 'bullets' on the control bracket. You'll want to make sure those aren't gunked up and their springs are good. T...

Speculating: If the roll pin is missing from the control-cam hub, it might look like an oil hole.

To clarify:
* Are you saying that the control knob (23 on the parts diagram) is remaining stationary while the machine is speeding up, or that the knob is rotating on its own?
* By "intermediate shaft" do you mean the speed-control shaft (18) linking the knob with the control cam?

Your 2.11" length sounds like the total length of the sheave. Is that correct? When you get the bearing off, what is the dia of the follower post? I measured from the inner flat to the outer rim of the sheave hub, so total length, right. I get 1-1/16 where you measured as well. I don't have it...

people have cracked the hub trying to get the race out I expect you're thinking of the Mark V setup. On the VII it's swaged to the yoke rather than the hub. The assembly popped out of the hub easily with a drift, a nice plus relative to the V. PXL_20201219_150801736.jpg PXL_20201219_150819337.jpg S...

So I was running a high-speed operation on the VII that took longer than I expected it would, and when I went to reduce speed to shut off it wouldn't move. I shut down, look inside, and yup, the speed-control cam was melted to the yoke on the control sheave. Arrgh! I've been thinking that the machin...

It's apparent that Shopsmith chose blade diameters primarily in consideration of available torque. Older models with less power are sized for 9" cutting blades, younger for 10". The much larger cutting face of a dado takes a lot more torque than a cutting blade, so you'll always use dado s...

Thanks for the tip. I'm interested n pricing norms.
