Topic tags/keywords: question milling

The local saw mill called me up requesting the help of my giant chainsaw. (Still 880r w/59” bar) They are looking to get some end grain slabs/cookies off of 40”+ diameter trees that will be turned into tables. In the past when I’ve done it for them we did 3” thick slabs but holy crap can those be heavy at that large of a diameter.

My question is, what is the optimal thickness of a cookie to help prevent cracking etc.. I know a lot of it probably depends on wood type so one of the woods is aleppo pine, one is olive and the other is some kind of hard wood.

Thanks for any help.

Any thickness will crack unless you use pentacryl. It really does work from personal experience.

It doesn’t matter what kind of wood. All will crack unless treated with pentacryl. People have tried putting metal straps around the cookie, doesn’t work

Thanks for your help. The woodcraft around the corner from my house has some pentacryl.

This is what we cut up yesterday. I ended up cutting 15 cookies and kept 2 of them.

That’s a heck of a chainsaw, wish I had one, bet it would come in handy quite a bit.
