Well, it sort of worked, but there are issues:I am especially curious about the Mach 3D. The handle slewing pivot seems intriguing.
- A steel head is too heavy for the strength of the built-in spring. I'll need to dig out a featherweight.
- Fit can be good, but the fastening it is somewhat tricky, because the plastic parts of the head are flexible.
- It seems that using a neutral/negative exposure head is best for this.
I tried a dscosmetic Mars head with a Mach 3 cart skeleton head. It sort of worked, but not well. The screw became a little loose after a few strokes. The (slightly) positive exposure made it a touch too aggressive in any case.
Perhaps a spring could help, but I'm thinking that maybe a 3D printed mechanism might be better.
A small thing like a spring between the handle and head, could make it more resistent to pressure, if not able to pivot to follow skin contours.
