Mark VII upper assembly

[JPG]

First step is to place the lower tubes in the base.

The right endcap goes onto the two tubes. They bottom out in the endcap bores.

The tubes are secured by two set screws from the under side of the endcap.

The rear way tube is inserted into the right endcap and secured with a set screw on the top side of the endcap.

Next the carriage is slid onto the rear way tube from the left.

Next the front way tube is inserted through the carriage and into the right endcap. Set screw is tightened after next step.

The way tube must be rotated to center the gear rack in the slot.

The table is inserted into the carriage and the table is 'lowered' against a block so the table posts supports the way tubes.

The headstock is 'slipped' onto the way tubes. This is not easy since that headstock is heavier than a Mark 5/V. Also the gear adds another thing to 'align' in addition to the headstock clamps. Fortunately these are visible from the outboard end.

The headstock rack clearance is checked.

The left endcap goes on next. This proved more difficult than the headstock. All tubes are the same length, so the tubes must line up(all 4 at once).

The endcap is pressed to bottoming out in the endcap bores. the set screws are tightened.

And raised to vertical right(drill press). This thing is really difficult to raise with the headstock all the way to the left(high in drill press position). The headstock is heavier, and the pivot is closer. The table etc' are lower than a Mark 5/V.

Drill press close up.

Raised to vertical left(shaper mode).

Finally a more 'traditional' setup.

The carriage lock has not yet been adjusted(nor a lot of other things).

I don't know if I should post in this, and I will delete it if I need to, but why did the Shopsmith simply not continue in this design? It seems with the geared headstock, reversing motor, and double tilt, it was way ahead of, and superior to, the Mark V at the time.

Just curious.

I do not know. It has a bunch of stuff that reappeared in the 505/510/520 upgrade.

Also there are those two design flaws made of nylon.(cam, gear rack)

The headstock is much more complicated and the base requires more assembly.

And we do not know if the Mark VII trademark and tooling came from Magna American to SS Inc.. And the production documentation?

This is as good a place to raise the question as any. The intended stuff for this thread is 'done'. Sorry I do not have the answer, just conjecture;).

Looking good in Gold! All these machines look better, IMO, with the two tone vintage color schemes (Green or Gold).

I just finished looking at your post on the restoration. This one and your related ones of teardown. For me this is the first Mark V11 that I have looked at. I have owned and used my 510 since 1987 and have never looked at one of these. You have really done a good job. You wrote the book ! Did you work for Shopsmith ? How did you learn all of the procedures ? I also have wondered why the gear for headstock movement was not carried over to the Mark V. Thank you for the class. Ron

Grossly tardy responding, but here goes.

I did not work for SS(or predecessors).

I am a stubborn old fart who has always tried to figure things out by myself. Not always successful, but I learn from trying. I do try to find out before 'exploring'. In this case I was pretty much left to my own resources(analytical and deductive thinking). As such it is prone to being mis guided!

Realize the Mark 5 preceded the Mark VII. The Mark V 500 is the same design as the Mark 5 with few alterations/'upgrades'.
