Hi All:
This is from a OT question on another forum. (Details of use below.) The problem is finding a miniature router round over bit (or ogee bit) of
1/16 inch radius or less. Metric sizes would be OK. A hand molding plane of small size might also work.The original poster in that other forum found small router bits that fit a Dremel like hand rotary power tool with an 1/8 inch shank, . A small router table was built to house a Dremel tool with the bit sticking up. However, when getting bits for Dremel like tool from a 3rd party, the quality of the HSS used and the sharpness of the cutting edges leaves LOTS to be desired.
For artistic reasons (and only for artistic reasons), a round over bit is needed for some woodworking scroll saw fretwork. Stock thickness is somewhere between 4mm and 6mm. Length and width about hand holding size. Needle files, Dremel rasp bits, and sanding don't have the uniform look wanted. I looked for a manual mini-hand plane, say something a Luthier might use, but no luck. Although, how the mini-hand plane blade get sharpened, I don't know.
Hand made Scraper blade? I seem to remember Roy Underhill doing a TV show about making a hand made scraper blade to do beading work. He made the scraper profile from an old rusty saw blade. I seem to recall it was WAY too much work to hand make such a tool. (had to make mini forge to soften blade metal, cut, and re-harden the steel.)
