Initial sanding of Madrose (Dalbergia Baronii) for the first time, expecting it to be pretty resinous and the sets are all pretty thick.
I'm using cloth backed zirconium abrasives - should I start with 60 or 80 grit?

_________________
The name catgut is confusing. There are two explanations for the mix up.

Catgut is an abbreviation of the word cattle gut. Gut strings are made from sheep or goat intestines, in the past even from horse, mule or donkey intestines.

Otherwise it could be from the word kitgut or kitstring. Kit meant fiddle, not kitten.

40 grit light passes., then switch to 60 grit when you get within the last few thousandths.

I'm close to what Aaron does. 36 grit to about .5 or .6mm over final thickness. Finish with #80 cabinet scraper.

I start with 60 grit till .125, then 100 grit to .105, the 150 to desired final dimension which for me is always .090 for back and sides. Tops are different.
