rick@whydoit.com Posted March 6, 2012 Report Share Posted March 6, 2012 I have some sycamore that's been sitting in the garage for about a year. One board I wanted to use has a pretty nasty twist in it. Thinking I might be able to tame it, I ripped it on the bandsaw. Then those pieces - 2 at least - twisted further. The goal was to rip, flatten and glue back up with 2 other, wider boards to make a desktop. One piece, I tried to take the twist out on a jointer. The board started at 5/4, one side is now 5/8. And there is still a bow in it. A second rip I've tried to get the full length to sit flat on the bench by hand planing the twist out. Still has a bow. This one is the hand planed one...

It is probably case-hardened, where the boards weren't dried properly in the beginning, and have internal stresses that are exhibited until they are cut. I have had some boards like that. No matter how long or how carfeul I was at drying/jointing/planing them, I just couldn't get the twist out. i just had to give up and get different boards. I wouldn't think they are unusable, but probably not for a large top. Maybe you could save them for something that needs shorter peices.

paoloberno Posted March 6, 2012 Report Share Posted March 6, 2012 If you have a twisted or cupped board you should crosscut (half the board half the bow) not rip because ripping release even more stress Quote Link to comment Share on other sites More sharing options...
rick@whydoit.com Posted March 6, 2012 Author Report Share Posted March 6, 2012 Normally, I'd agree on the cross cut - but these were already rough cut to length. The longer board, also twisted, twisted after cross cut to rough length, then again after rip. Quote Link to comment Share on other sites More sharing options...
CessnaPilotBarry Posted March 6, 2012 Report Share Posted March 6, 2012 I might save that stock for future boxes, business card holders, and small picture frames. Quote Link to comment Share on other sites More sharing options...
