Coop Posted August 22, 2021 Share Posted August 22, 2021 Matt Cremona recently did a park bench build where he used thermal treated ash. He did a review of the wood at the end and the cons far outnumbered the pros, but he said if he had to do it over again, he would stick with this wood. Have any of you guys had experience with this stuff? Quote Link to comment Share on other sites More sharing options...

Have any of you guys had experience with this stuff? I haven't used it and, frankly, I'm not even sure if I can get it... From what I understand, it's great for outdoors stuff but, a real PITA to work with because it doesn't mill well.. Quote Link to comment Share on other sites More sharing options...
Coop Posted August 22, 2021 Author Share Posted August 22, 2021 One of my hardwood guys has it at $5.25 bf compared to regular ash at $3.65 bf (4/4). Matt said that on real tight mortise and tenon, dry fit, he even had the mortise pull out when he tapped them apart. I think I will stick with some 12/4 pecan slabs that I cut down 3 or 4 years ago. Not sure how pecan weathers though. Or maybe just buy some cypress as I’ve had good weathering experience with it, even though the color is a little bland. If I recall, the color was one of Matt’s few good comments on the thermal stuff, that and the weather resistance. Quote Link to comment Share on other sites More sharing options...
Woodenskye (Bryan) Posted August 22, 2021 Share Posted August 22, 2021 I have never used, but I think it is hit or miss. If the process is just a little off the wood can be brittle and hard to mill from what I have researched. I would probably try something else unless the price was so much cheaper.

Coop Posted August 22, 2021 Author Share Posted August 22, 2021 And that’s what I don’t understand from Matt’s video. He mentioned that the wood is just one step from being charcoal but was treated in a non oxygen environment and was super easy and fun to mill. Then he said that the edges were super brittle and wayward. Just wanted to get others experience with this stuff. Quote Link to comment Share on other sites More sharing options...
Woodenskye (Bryan) Posted August 22, 2021 Share Posted August 22, 2021 Supposedly you put the wood in a chamber (kiln) without oxygen and then it is cooked. So if the wood needs to get to 1000 to 1005 degrees, if it goes over that range it is charcoal. I didn’t watch Cremona video but he seems to contradict himself saying it’s great, but edges brittle. I would try if given, but not sure I would be confident in it being done right and waiting my money. Quote Link to comment Share on other sites More sharing options...
Coop Posted August 22, 2021 Author Share Posted August 22, 2021 All in all, it’s a neat design and I think I will spring for cypress and go for it. 1 Quote Link to comment Share on other sites More sharing options...
