IME most hardwood scorches because of the resin content. I've got
various bits and bobs lying around, some of which are at least 150
years old, and they still bleed resin when cut. I would test the
blade on sheet materials or decent quality softwood.

Not my experience. I'm using some oak obtained when an old teacher
training college closed. Judging by the style of the construction the
general finish and the age of the school this furniture is at least
70 years old. Cutting it on a table saw gave no burning. It mostly
cane out of a lab.

There was also some pine among the items and it had the most
beautiful scent when re-cut.

Nearly all gone now into Versailles planters.

Similar story with some native oak we re-cut out of an 8ft log some
15 years ago and air dried. Bugger to cut but no burning and the
appearance of the quarter sawn boards is beautiful. The reason we
re-cut it ourselves was to get the best of it quarter sawn

Good sharp blade and right speed of cut should give good resukts.

What hardwood were you using with a high resin content ?


The one I remember specifically was beech. The blade was well gummed up
after cutting. Some unspecified fruitwoods, although soft in texture,
also gave problems. I think maybe the blade hits a resin "pocket" now
and then. Actually, oak has never given me problems.
