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
maybe 1 1/2" diameter. I think that geometry about works, and
precision is not critical. I'd run a bunch of profiles and then chop
them off at 3/4" lengths.
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
TIA. -- Jesse
