Thought i would get a blue print co. to copy my mylar master rib ( 1 or 2 copys ) onto mylar--- so I can sacrifice the copys. Thinking of using a new exacto to cut out the copy
perhaps at the inside of the BOB marked line. Then use a fine mechanical pencil to trace it onto the MDF. Then rough out the MDF- the do a close cut on the band saw to within
1/16 or less...... the I THINK i can simply put a sanding drum in the router and carefully trim the rest down to the line. Should be able to get pretty close that way. maybe a fine red
sharpie might be better to make the mark than a pencil --- maybe I should prime the MDF white to see the line better --- and it might prevent the sharpie from bleeding out wider and causing
confusion and ruining the precision Im going for.
Does anyone know if a sanding drum will be balanced well enough to run in the router at its lowest speed ? Never tried that before..... should sand nicely if it doesnt blow up :-)
Dont know what its lowest speed is--- have to look that up....

PS - the sears router is 12k to 25 K RPM. So the drum would have to withstand 12,000 RPM (!) Just called woodcraft and they confirmed that
12,000 is way too much for a sanding drum. Now that I think about it - I remember it being some off-center even in the drill press a low speeds....
Its really just a rubber stopper --- effectively--- no way to control its centering. A vert. spindle sander would be nice......
