This is a follow-up to the "smooth-cutting rip blade burns cherry" thread.
Some comments were made suggesting that setting the blade height higher above the workpiece would allow the blade to cool more and burn the wood less.
Howard Acheson quoted a Freud rep as saying that "half a tooth above the workpiece" was the correct setting for all Freud blades, assuming you were using the right blade foer the job. This is obviously a very low setting.
Tage Frid, an old master whom many of you may know, or know of, said that he always set his blade at the maximum height because the blade would be cutting downward when it enters the wood and there's less potential for kickback.
If you look at the direction that the blade is trying to move the wood with a high setting versus a low setting, there's a very big difference. Tage's rationale makes sense to me.
The "blade cooling" comments would also support a high setting.
What do you think?
