Hi
I need to change my X axis reduction to 4.7:1. The ratio works out
to a 72 and a 15 tooth HTD timing pulley. I`m wondering if the pulley
is too small to bore out to 1/2 for my servo shaft. Also..I`ll take a
guess that there isn`t much tooth engagment with a 15 tooth. It seems
the HTD series only goes to 72 teeth. Does someone know of a source
for a different class of timing pulley that goes higher then 72 teeth.
