Here are several photos of
Paul-Ernest Levesque's TINKER,
which he built without castings.

The first two photos give over-all views of Paul's TINKER, and the grinding wheel arrangement he uses, which seems to feature a diamond wheel on a shop-made spindle driven from a motor mounted in the white plastic bracket behind it.

This graduated handwheel drum gives finely controlled advance of the workholding head towards the grinding wheel:

The screw-adjusted arm running from upper middle right to lower middle left in the photo below (also visible in the first two photos above) allows fine adjustment of the tilt of the vertical leg of the TINKER, thus controlling the cutter's radial position across the face of the grinding wheel.
