Been thinking about this for awhile. Did several elaborate drawing. All of which would have made buying one probably cheaper.

Today I remembered two things KIS (Keep It Simple) and William of Ockham- All things being equal the simplest solution is usually the right one.

As of right now all that I have invested is time and some odds and ends I already had on hand. Probably gonna buy some set screws that match and figure a locking pin for each position. Still almost nothing spent. Cheap is good.

Tomorrow I'll test it out.
