Also, what does this little red nob do? I see that it turns a little cam on the inside of the belt cover, but not sure of the function of that cam. Does it lock the headstock down? it seems a little small for that.

Better image of the notch in the control cam.

cleaned up control cam image. I guessing that the top isn't supposed to be "notched like that. I'll upload another file

How far down the way tube should the rack go? This is about half way down.

What is this? Came in the box of parts, but I'm not seeing where it fits. Is this a vaccum part?

Just picked up my mark VII. Really excited to put it to use.
It runs in both directions, but the previous owner said that it slips into higher speeds. Is this a control can issue or a belt tension issue? I haven't investigated yet.
What other things should I check for before working this machine out?
2 pieces, three rivets each - about 30+ ". Only has to go till the carriage and carrier bump against the far end.
no clue.
Maybe, could judge better if it was visible(clean that crud off ).
Drifting towards higher speed may be a motor belt too narrow(< 1/2"), or the dial detents letting it slip.

doh! I made that original post on my phone, didn't realize the cam had a few years worth of stubble stuck to it. I updated better pics in the original post just to keep everything clean. Didn't put a caliper on the drive belt to get the thickness, but it did feel a little thin when I took the belt cover off. THis came with a spare belt, so I'll be replacing that.
The little red knob engages/disengages the spur gear to the track to allow sliding the headstock without 'cranking'.
Notch on cam caused by ??? Possibly due to revolving too far towards fast and rubbing the control sheave hub.
Spare 'red' cam. Lucky you. Source?????
Spare motor belt. Ditto!!! IFF oem.
The rack gear looks very good(that part exposed in the pix).
Other than the notch, the cam also looks very good.
I think you got a good'un!

red cam was printed on my 3d Printer with high impact ABS.
Once I have the design tweaked, I'll make the files available for any that want em... Unless, of course, that would be a violation of the board's rules.
I'm glad to hear it. I'm going to start cleaning it up tonight and can't wait to use it.
I do not see how our sponsor would have reason to object to someone creating a solution to parts no longer available from them.
