Aah...Hadn't even thought about that as I haven't painted yet. Thanks Adrian!
Yep, You have a little chatter there as well, which can really affect tearout.
Your machine may not be as rigid as Michael's, so you may have to reduce your pass depth as well.
Every machine is different as well as species, you'll have to tweak it for yourself to keep the bit cool to the touch, and get the quality of cut you want.
Faster growing trees aren't as dense, and more soft wood between the growth rings for tearout.
In Connecticut you should have Sugar Maple readily available at reasonable cost.
It might be worth your while to check out as cuts are generally much more consistent, and less problems.
Sugar Maple can generally cut and hold detail better also.
I've got a lot of Hard Maple chilren's blocks, and Dad mistakenly ordered soft maple blocks twice...MASSIVE difference in tearout and rejects.
A lot depends on the bit as well.
In Sugar Maple pics of a project I'm doing, with Drillman1's .125" 45 degree 2 flute(all the regular VCarved words)...the speed was IPS .8,.4(plunge),17K and .06" passes.
The Tiny signature font was an Onsrud .25" 30 degree engraving single flute with a .005"flat at .5, .35, 18K.
Both had first coat of Earthpaint Linseed(no dryers)/Beeswax applied first, after sanding to final 600G.
Looking forward to you having good cuts!
