Mark 7 Pictures

Okay folks I have taken a few pictured as requested. I hope these are clear enough to give some idea of just how solidly the portions fit together. Most are pictures of the left end. One picture is shot of right end from the outside end. Please remember both ends are alike. Enjoy. Jim

I apologize one picture was posted twice. I attempted to delete that message and failed. I know it is difficult to pick up all of the features of the Mark 7 form these pictures. Someone in a prior discussion raised a question regarding the single circular fastener. If you note in the raised view there is a horizontal bar. When in the lowered and locked position that locking mechanism is totally solid. The other point to notice being there is no give on front or rear end when locked. I have also found that aligning is far simpler. Jim

Thank You!

The inside(knob/locking) is where my interest lies. i.e. is the knob a 'nut', 'bolt', 'clamp actuator'?

What secures the end to the bar. Why does that bar look familiar?:rolleyes:

FWIW the duplicate post can be deleted. Edit post, click on delete(more than one place) and for reason enter [duplicate].

Ditto what Jim said. It is essentially a 3 point lockdown. Two ends and the tangent (I hope I got that right.) of the conical pointed screw in the center of the opposite side of the rod. A shallow obtuse triangle.
One thing I found was that I had to realign all my SPTs after the conversion. That makes twice in the last year. Once with the PowerPro, again with the Double tilt. The Thickness Planer was the only one that worked because it sits on the way tubes.

Due no doubt to different positioning of the castings to the bench tubes and the way tubes and the idler shaft rotational position.

i.e. That would be expected unless measures were taken to eliminate it.

The thickness planer connects to neither 'variable'!;)

I am uncertain why the bar/rod is familiar to you. The bolt is pointed on the end that screws or wedges under the edge of the rod securing the hinged portion down in place. It actually reminds me of the screw that secures the tubes in the drill press position. Both ends are alike and hold the tubes very securely. Jim
