I need to make a lot of small hourglass-shaped rollers and I don't have a lathe. The finished roller will be 3/4" long, 3/4" outer diameter, and taper in about 3/32", so a net 9/16" diam at the middle, if I have the math right.
I am thinking of starting with a 3/4" diam dowel and then using a router with a core box bit
Does this sound workable and safe? Alternate suggestions? Any tips for how to secure the dowel, start the cut, and rotate the dowel? While I am fine with some shop tools (TS, DP), I am a router newbie.
OTOH, if anyone knows where I can buy such things ready-made in wood or plastic or even rubber (no luck at McMaster-Carr), please let me know. I think such things exist, but I don't even know what they are called.
TIA. -- Jesse
