Greetings; Mouse miss-fire before; The lids for these chests were the first things I tried to make out of this crappy, poorly seasoned & dried mahogany.
So by now they've had about 90 days to warp, and warp and wind they have done. Now I know its a popular thing to warm up oak in a steam setup, getting the lignite in the oak above 180F softens it and allows it to be bent, and it will retain that bend when cooled again. I'd druther not use steam as this stuff reads 5% and below for moisture, and if its temp alone that allows this, it stands to reason that lignite is lignite and I'd ought to be able to heat this mahogany, and rather than bending it, take the bend/wind back out of it. So obviously I have to make a chamber big enough to take these lids, all 3 of them, which with the bearboards ends and all are around 1 and 1/16" thick, around 23" wide, and about 47" long. Thats a 2x6 frame for height, and half a sheet of plywood for top and bottom. But without some insulation, hard to heat. So I am contemplating giveing it a wrap with some 2" blue styro, thats r11 by itself. That should, because it reduces the cooliing at the far end away from the heat source, even the internal temps. As for the heat source, I'm considering demolishing an old hair dryer, mainly to remove the plastic as much as possible, at least cutting off the handle, and doing a light dimmer type of control externally to set the heat. I don't care if it takes days to warm it up as theres probably 40 lbs of wood to heat without scorching that which is nearest the heater, only that it does get hot enough eventually. The slower the better and more evenly would seem to be best when dealing with 1/4 a barn door sized stuff. So my lack of info basically consists of how hot do I have to heat this mahogany to the point where it will sag of its own weight and flatten, and, how hot can I get the outside of the box before that blue styro starts getting soggy? I can put a small probe thru the box resting on the high point, or even stack 20 some pounds on it to add some counterforce to the wind its taken, and by that see it start to flatten. But that may need 200F or a bit more inside the box. IDK about mahogany. Maybe this is something Les Watts can advise on? Maybe, because the wind is direction in-consistent, I might have to heat each one by itself. Advice needed OIW. Many Thanks to the wood people I know there are a few of here.
