What's the Deal on the original Mark VII 's Any good?

I had e-mailed him. He said it is a repaint, the vacuum has been removed and the speed changer has been replaced with a standard mark 5 speed changer. I didn't know you could do that!

Gad!!!!!! How did I miss that????????

Seems feasible! Wonder about the idler shaft.

Another exercise on the do someday list

I thought for sure you would have spotted that first! The ability to convert to a Mark 5 changer seems to be a huge perk! No more chasing down aluminium speed changers!

You can do pretty much anything. It just depends on how much work you want to do and how much money you have.

I would want to either remove (chop off) that blower shaft or put a guard over it. As a farmer exposed spinning shafts make me very nervous. I personally know enough seriously injured guys to make up a baseball team. Most farm stuff runs at a lot higher HP but it really doesn't take a lot.

I agree on both points. With enough time and money there's not much you cant do!
A homemade guard would be a wise choice if you didn't plan on putting a vacuum back on.

A preliminary look at the two different idler shafts, control sheaves, cam, and porkchop puts the control knob shaft locations very close. Do not know about side (headstock side to idler shaft spacing)(yet).

May try mounting a porkchop etc. to the MVII(no holes etc.), or at least see what is required.

I think a MVII idler shaft, mVII eccentric, mVII idler sheave, M5 control sheave, porkchop etc. might just work. Mounting the porkchop etc. would be the challenge. The MVII idler shaft is needed due to the extra length etc. The bearings etc. are just like the new MV/7 version.
