I'm in the process of doing some upgrades to my 20 year old Delta contractor
saw. One of the things I want to do is replace the cast pulleys with
machined ones. Looked at the set that In-line Industries sells According to
the company most blades spin at about 3450 rpm. They recommend running the
blade at 3800 rpm. Does anybody have any thoughts or experience on running
at the higher speed? Better, worse, or is there no notable difference?
Saw blades are designed for a specific tooth loading. Increasing the
blade speed means you would need to feed the wood faster to match.
However, that's only about a 10% difference. You probably cause more
variation than that just pushing the wood through by hand.
My guess is no real difference. The cynic in me says that they probably
make those pulleys for other purposes, or can source them cheaply.
This one is 3000 rpm
This one has more HP and is 4000 rpm
This one is 3450 rpm
I doubt it would be a problem and for thin stock could help the feed rate,
but unless you increase the power, it will not help on the 3" thick maple.
