Topic tags/keywords: oak

I’ve got 3/4” oak that’s already been planed and ready to build furniture. This wood has or had powderpost beetles. Who has treated with timbor or timbor mixed with antifreeze on ready to build lumber and what’s the best way to use the timbor and does it stain the wood in anyway. It has been kiln dried a couple years ago but I don’t want to chance it . I plan on building a dining room table with minwax tung oil finish

I treat what comes off my mill with Timbor mixed with water at the suggested strength (probably overkill). I’ve never tried antifreeze, I would think that would offer a greater chance of staining than the Timbor itself which I’ve never experienced staining with.

I hear you on not chancing it, I would hate to dump a bunch of time and effort into making beautiful furniture only to have holes and frass appear after it was in service.

I have never used it but my understanding is that Timbore mostly just sits on the surface of the wood and penetrates very little. It doesn’t really kill the existing ones until they try to emerge and it prevents new eggs infesting the wood. After treating it, I would let it sit for a while to see if any frass piles form indicating that beetles are still present. At first sign of more beetles emerging, I would take it to the burn pile. It could take up to a year to find out. IMO, the only way to really insure that the beetles are gone is to heat it in a kiln hot and long enough to kill them and any eggs that may have been laid.

Personally, I would not want to mess with wood that has been infested with PPB. Life is too short.

I agree with Lazy man it would have to be spectacular looking oak to keep me from burning it.
Buggy wood isn’t worth the time.
Good Luck

If it wasn’t kiln dried I wouldn’t use it.

I believe the mixture was a pound per 1 gallon of water.
I’ve also read about using borax to treat wood so that might be something to read about

Heat treating is another way to get rid of the bugs. If you can’t access a kiln make your own with clear plastic. Wrap the wood and set it in the hot sun for a couple of days. As I recall 140 degrees f for about 3 hours does it.
