I measured both the full size MK 7 and the shorty at each end and in the middle. As you see the numbers are all different. I suspect if I move them to different places in the shop the numbers would change.

MK 7 Left 23 1/4 Center 23 3/16 Right 23 1/4
Shorty Left 23 1/4 Center 23 %/16 Right 23 3/8

I must say that I am surprised. I thought that your floor was as close to perfect as is reasonably possible.

Except for the center on your Shorty, your numbers look very close to what I had expected. The numbers in the center I would expect to defiate more than those on either ends. A little sway in the tubes could account for that. Loosen the tubes and rotate them 180° to see.

The shorty center is 23 5/16 but I am sure you figured that out.


The cement guy that floated that floor did a great job. Yes it is as close to perfect as is reasonably possible for a 30' X 40' slab of concrete.

I want to thank those who assisted with this endeavor.

I am proceeding with my plans based on the following measurements (to the floor):

center of main drive shaft = 38 3/8"

top of WAY tubes = 30 3/4"

top of BENCH tubes = 23 1/8"

In addition to these measurements, the flat platform on the legs (at the end of the bench tubes) will be used. I measure that platform to be 21 13/16" off the floor but I am calling it 21 3/4".

OK, now that the measurements are established, whatchya building?

Suspense:) I can't wait to see as well.

An extension table off the end of the Mark. The table shall rest on those flat spots (at the end of the bench tubes) and be supported by a third leg (may be adjustable). Ultimate goal - a setup for polishing tubes (tubes of all types).

If the purpose is to polish tubes I assume that the critical measurement is the height of the drive shaft off of the floor.

Mine is 38 1/4" above the shop floor. I am measuring from the sharp point of a forstner bit that is chucked to the drive shaft.

Dusty what makes a nice adjustable is a T nut in the bottom of the leg, a predrilled hole and then get a set of those threaded "feet" that will thread into the T nut.

you will almost definitely want some sort of adjustment on the support leg.

Either the T-Nut or an adj. slot system. If you move your SS around the shop, You will have a convenient and quick method to get everything leveled.

I hope that I have that covered. I have two adjustable supports left over from my RV days. These have threaded inserts on both ends for fine adjustment and spring locks for course settings.

Those look perfect. and "already own" is the right price.
