Timboslice Posted February 20, 2017 Report Share Posted February 20, 2017 I have rosewood planks. I'm starting a project that required 1/2" square strips. Immediately after I cut it, they curl so bad that it starts to bind the saw blade. This never happened to me with softer woods but my project requires hardwood. Does anyone know what the problem is?

davewyo Posted February 20, 2017 Report Share Posted February 20, 2017 Sometimes you get lumber which will cup like a son-of-a-gun when it is cut. Try cutting into another board, if you have one. Quote Link to comment Share on other sites More sharing options...
wdwerker Posted February 20, 2017 Report Share Posted February 20, 2017 Check the moisture content. If you don't have a moisture meter weigh one of the curled strips on an accurate digital scale, record it and weigh every few days. If the weight keeps lessening wait until the weigh stabilizes for a few weeks. If the weight is stable then the wood either grew with tension in it or was poorly dried.

Ronn W Posted February 20, 2017 Report Share Posted February 20, 2017 Sometimes there is just a lot of natural stress in some boards and they will curl and maybe try to bind up your saw blade. I don't have a could solution other than to try a different board. I would keep a couple of wedges or a flat screwdriver handy to jamb into the the saw kerf behind the blade to keep the kerf from closing up while you complete the cut. Be careful reaching across the blade. 1 Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted February 20, 2017 Report Share Posted February 20, 2017 It might pay to make your initial cuts with a bandsaw, if you have one. Ripping stock that binds on the table saw is an invitation to disaster. At least, don't stand directly in front of the blade! 2 Quote Link to comment Share on other sites More sharing options...

phinds Posted February 21, 2017 Report Share Posted February 21, 2017 As has been said, you either have reaction wood or unseasoned wood. Based on how extreme you say it is, my guess is reaction wood. Quote Link to comment Share on other sites More sharing options...
AceHoleInOne Posted February 22, 2017 Report Share Posted February 22, 2017 Yep it happens, it could be the wood wasn't kiln dried properly causing case hardening. Or just natural stress in the wood. Relieve your stress and find another piece of wood. -Ace- 1 Quote Link to comment Share on other sites More sharing options...
