Default Hand Crank Discussion

hey folks,

I have had a couple people approach me regarding this age old issue.

I am SO new to this whole world that sometimes I think things are possible when folks who know WAY more say "been there, tried that".

With that admission up front I would like to enlist the aid of anyone who feels like helping.

The goal is to produce one of the following:
1. A complete handcrank mechanism with 3:1 gears that can be mounted on "non-bossed" machines WITHOUT drilling new holes in the head.
2. An attachment that will allow non-bossed machines to use existing Singer or PRC handcranks.

Makitmama sent me this photo of a rare 127 conversion handcrank

What I am looking for right now is a photo of both types (this and the PRC version) from the angle of the red arrow looking at this area.

Also a photo of diagram of how the area indicated by blue arrow looks on a "normal" treadle machine.

I like the idea of a clamped on mount at the shaft that then arc's under the handwheel to the handcrank.

If there is a point at the red arrow area that will allow mounting (bolting, etc) then we could be good to go.
