Post Amateur wood worker seeking tree trunk drying advice

Greetings!

I am an amateur craftsman who is trying to dry out a chunk of sugar maple tree to use as a wooden frame for a circular stained glass sign. The chunk of trunk (heh) currently resides in my garage and it is growing mold. I know for certain that it will crack and I would like to minimize it if at all possible. I would also like to get rid of that mold (10% bleach solution?) and would like to know the best way to do so!

Best,

EDTAKiller

Prtessure wash it ....

Then apply your bleach solution. Maybe 4 to 1. Leave it out in the sunlight to dry, but be careful of checking. Do not dry too much at one time. Use a blower vac to blow away the water. The bleach should kill the mold. Then bring it inside where it's not humid or damp.

Woodturners use anti-freeze to stop larhe chunks from cracking ... etheylene glycol. Search for that technique to see how it's done.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

The mold won't penetrate very deep and will die out on it's own if you keep it dry. More important is to coat the ends of the log with something like anchor seal or even gulf wax. This will minimize the wood cracking. The bad news is it's going to take a very long time for the wood to season. It make take a couple years for every inch diameter the log is.

Are you sure it is ethylene glycol? It is poisonous I think they were using propylene glycol, but I might be wrong, it isn't poisonous it is even used as a food additive. It was the only antifreeze we could use in chillers,just in case the back flow preventer malfunctioned, it wouldn't poison the buildings water supply

If I recall right they used to heat it up and keep the wood in there for quite a while, called it grain stabilization it was in the early 80's that was all the craze

Woodworkers use PEG1000 (Carbowax 1000, Macrogol 1000.) Wood soaked in a warm bath of it has the water displaced by the PEG and becomes stabile w/o shrinking. The drawbacks; it takes a long time, bath needs to be kept warm. It affects many finishes in undesirable ways. Google it.
