I have a 1970 Delta 18″ planer with sharpening attachment (motor driven grinding and honing). The belt that connects sharpening motor to grinder is round rubber and stretches quite a bit to go onto pulleys but produces very little tension because of stretch. I have tried to replace it with regular 23″ belt but would prefer round rubber original(sanitare vacuum has a similar belt but not long enough). Please advise.

I wonder if several pairs of nylon panty hose twisted together would work. Use a knot that allows for adjusting the tightness. Just a thought.

Take a look here and see if your machine is listed.

You mean Rockwell 18" planer. Round belts can be gotten at http://www.mcmaster.com and are available in different diameters and can be cut to whatever length you need.
The 18" planer is a wedgebed table model. Very nice machine and was going for $8,000 when they stopped production in the early 70's. Know the machine well. A friend has one as do I and I used to service them in various high schools.

Thank you for the advice. McMaster's had what I needed, they were polite, prompt. The belt fits better than new.Thanks again
In RickL"s profile he mentions adjusting wedgebed planer to avoid
snipe. What are the words of wisdom? Table rollers, pressure bar ?

Snipe is caused by the bed rollers in most large planers. Set the bedrolls a few thousandth's above the table. Obviuosly the other rollers should be set to spec and the pressure bar should be set just below the cutting circle by a few thousandths at most to allow for dulling knives or the wood will hit the pressure bar. Some older planers have a fixed pressure bar so there is no margin for error while many of the newer planers have spring loaded pressure bars to allow for variation. Some of the big older planers like Buss, ect have a pressure bar adjustemnt lever to allow for quick adjustnment as the knife grinder will change the cutting circle.
