Mark V VII Stand

Reason for need to reverse rotation.

When flipping to under table shaping, the shaper cutter is now inverted also(upside down). That is, what was the bottom(table) end of the shaper is now the top end and vice versa.

If the table/cutter positioning does not matter, then the rotation does not either. With straight bit routing it does not matter either.

This is not the complete tale however. A shaper fence is also being repositioned relative to the cutter. From the operators perspective, it is still the same, but relative to the headstock and it's rotation flips.

Having the ability to reverse rotation allows mounting the shaper cutter either orientation.

HOWEVER: One must keep track of the proper direction of feed. When the cutter is reversed(either on the arbor or by flipping the table) the feed direction is also reversed. i.e. plow vs climb cutting. Plow cutting pushes the workpiece against the fence(OK). Climb cutting pulls it away from the fence(not good!!!!!).

My confusion re parts mix has to do with the 'meaning' of 'base'. To me the MVII base is not the part containing the way tubes etc.

From your latest pix, I think you are wanting to mount a Mark 5/V way/bench tubes and end caps on a 'bench' and use the 'normal' pivot for drill press use, but add the ability to tilt the other direction for under table shaping etc. that pivots similar to the MVII that places the headstock and table lower. That would mean a short 'bench' with pivots like a MVII on the end opposite the 'normal' M5/V pivot.

I think that could be done(IIUC), but the release for the 'normal' pivot end would would need to be created. The Mark 7 end cap does that. A Mark 5/V end cap can be modified similarly(done that already;)). A Mark VII type pivot/catch need be created for the other end.

Damn this is intriguing!!!

Interesting idea! Eliminates a Mark VII shortcoming(drill press too low:D).

This way it's good on height on both ends. Low on the left for under table and tall on the right for over table.

Using Google you can search books which will pull up the old archives on Popular Mechanics. I believe the full article was available for building a Mark VII type stand in place of the legs on a Mark V. With the tilt you ended up tubes much closer to the ground like a Mark VII. Unfortunately, I'm having no luck finding it today, but I know I read it a couple of years ago. You'll find searching through Google Books a little bit of a challenge because Shopsmith also bought ads in those publications.

In fact, I think this picture is from that article.

Having that article helped, I searched the title and it was right there. August 1967 Popular mechanics.

Notice it is for a Mark 2, not a Mark 5V. FWIW, those M2 end caps already have tilt/release ability(precursor to the M7 design).

I don't think reversing would be necessary, I use shapers every day and feed material from right to left. In my head this would not change ? I've attatched a crude drawing of what I'm thinking of.

I don't know all the ins and outs of table/fence adjustments on the SS.

Something as simple as this could hold it either way. Again, excuse the crude drawing.

That is 'like' I understood.(sorta:D) I like yours better. You could possibly use MVII bench tubes and MVII pivot brackets(for the 'left' end), but the tubes are 3/4" shorter(52") than Mark 5/V ones(52 3/4") which I think is not a severe problem. May need to insure proper positioning under the clamps. Realize that would be a weakness compared to the MVII which had captive bores for the tubes.

As for your daily shaping, move the fence to the other side of the cutter and then reconsider the 'need'. And yes there is need for inverting the cutter(ask Charlese:D).

Beware!:eek: Over exposure to things makes one assume commonality with things slightly altered which is not always a prudent/correct action.

I think the easiest way to 'solve' the table post orientation is to get a second M5/V table and reverse the posts(places gear teeth on opposite side).

If I did this I would have measure exactly where the MVII tubes pivot hole would be and if that would work. Also if the brackets fit between or outside on the V lower tubes.

My only serious injury, while woodworking, was while I was trying to use the shaper. To this day, I am not certain just what happened AND to this day, I am "frightened" of the Shopsmith being used as a shaper.

Shaper or molder?
