Mark VII Main table breakdown

First a tour of the table underside. There are differences that make it unique.

It has two trunions with clamps. This is the rear one.

And this is the front one. Notice the tilt scale range is + - 90.

No surprises here. Just like Mark 5 etc.

The extension table can be attached to the main table. Notice the two set screws. They provide the 90 degree stop adjustment. The extension table tube bores have tapped holes for securing(1/4" -20), but nothing to put into them. I do not know what the original design was(I have misplaced my MVII manuals). The right stop screw is jammed - it obviously was not 'functional'.

And the left side. Notice two more 90 degrees stop set screws.

The trunion attaches with 4 screws and 4 thick washers. No shims were there.

The rear trunion (just like a Mark 5). I will use blue loctite rather than additional peening on the wrench retainer.

Front trunion same as rear but scale is unpainted and has the tilt stop adjustment screws. There are only two stops [ 90 and 45 right]. There is no 45 left tilt stop.

The tilt scale is also just like a Mark 5. I do not understand why, but almost all used tables I have taken apart have a bent stop pin. Not good since the pin has been reduced in od for the mark V etc.

Again just like a Mark 5.

I was surprised that there are two pins(one on each side) holding the tubes to the trunion. The pins are not tapered, but the inner end has been squeezed to increase the 'interference'.

Still 'attached' after trying to force from the 'access' hole. Notice the depressed end of the tube. If heat does not help get them off, they will stay.
