    is this a dumb idea?

    So we are having very unseasonable weather here in central / western NY. Yesterday as my son was coming home from school he put his hand on the front door and said this is really hot. I took one my Covid-19 purchases (instant read thermometer) and the surface of the door was 168F. It was hot enough that my wife's Easter sign had parts failing due to the glue not adhering. The door faces south east and the storm door is double paned.

    I have a few pieces of white oak that I really would like to sterilize, just to be sure as I bought of off CL.

    Is this a dumb idea or more specifically will this accomplish what I am attempting to do?

    Only one way to find out. My guess is it will crack. When drying wood the EBAC charts I follow allows a maximum temperature rise of 25F/day until you get to set point. Cooling down is limited to 40F/day. White oak cracks just looking at it to long. I'm not optimistic you will accomplish what you want w/o damage to the wood. An easier and less risky way would be to put the wood, stickered, in an enclosure of insulating foam panels along with an oil filled radiator heater and fan. Leave the fan on the whole time. Heat it up no more than 25F/day to 135 - 140F, hold for 12 hours, then cool down no more than 40F/day.

    Why do you want to sterilize the wood? Are you making tongue depressors?

    If you use enough AD lumber you'll know why.

    Showing my ignorance here, but I also wonder why. If it's because of Covid, I wouldn't worry about it after it's been sitting around for a few days - and I'm someone who worries about Covid. If he wants to kill worms or something - I can't help there.

    Yes, it's about killing bugs. AD wood can sometimes be infested with PPB, moth larvae, etc. Commercial kiln dried lumber has a sterilization cycle at the end that heats the wood up above 135F which will kill any insects, etc.

    If your technique works you might be shocked when you put that board on your table saw. Hopefully it won't shoot back at you like a bullet but its possible.
    BTW I heard that a couple minutes in direct sunshine will kill the virus.

    Sorry...should have been more clear. I had a small stack / 4 slabs (isolated) in my garage of WO slabs. There is clear evidence of PBB i.e. piles of saw dust mounds and / holes. Before turning into supply for firepit, I was curious if there any home made saving / sterilization techniques. Post has nothing to do with virus. I did dry one as picture was shown and board checked and basically cracked in half. Decided not worth any further effort and turned into chunks for firepit.
