« Part 1: Equipment and first batch Part 2 of Wood stabilizing series Part 3: Unwrapped and unplugged »

This morning the wood came out of the resin. I used blue gloves, and wrapped the pieces in aluminum foil, with at least one layer of foil between each piece. I did the little packets of wood “flat” so they would heat more quickly.

For the 24 pieces of wood, I ended up with five packets, which I piled into the toaster oven. I tried to make sure air would be able to circulate between them and turned on the convection fan in the oven.

Curtis says in a hurry, you can check the wood after an hour or two, but I’m not in a huge hurry. Half-cured wood will be junk, as you can’t re-bake it to finish curing it if you pull it out too early and let it cool, so I plan to give it at least 3-4 hours, which will mean resetting the oven in a couple hours.

As I was wrapping up the wood, the thing I noticed (sorry, no pictures – didn’t want to risk getting resin on my phone) was how some of the wood got a lot darker (pine, butternut, redwood, maple, birch), while other looked almost untouched (holly, hickory, hackberry and the elm, which really surprised me). The real test is how it looks and works once it’s cured, but I can’t help speculating about how things are going to come out as I sit here waiting for the heat to do its thing.

I hope you will show us the finished product. I did click on the link in your first post. I found it very interesting that coloring could be added to the cactus juice. I’m looking forward to seeing the wood after ‘toasting’.

Will do, Mike. I wanted to jot down these thoughts while I had time while the oven is baking. Now I’ve done that, plus cleaned the shop a little. A couple more hours until the wood comes out, and then I’ll take pictures and get a post done when time allows. We’ll see what my sweetie has planned for me today, but you should have less than 24 hours to wait for pictures.

Do you worry about the aluminum staining your wood. It seems like aluminum is very reactive with heat and chemicals.

A little, Earl, but it’s what Curtis recommends. If it causes me problems, I’ll figure out something else to use. It only needs to bake at 200F, so almost anything will work, as long as it’ll keep the liquid resin from running all over the inside of the toaster oven.

Just flipped all the packets around now, and reset the timer for another two hours. I’m hoping that’ll be enough time to cure it all. The wood needs to get to 180F all the way through, which shouldn’t be a problem for these thin pieces (I think the thickest is about 1/2”).

I would think that any discolorations due to the aluminum would only affect the surface of the wood, which I assume will be eventually shaved away. Probably not a problem in your case.

No discoloration I can see from the aluminum. More in the next blog, which I’m starting to write now.

Hey D’P’... a package like that

sells for $1,000 an ounce here in Churchill… and that was before the bykie enforcers moved in!
