Hope this is the right venue for this question?. I am a struggling Large Bowl/Platter turner and can’t find information on the possiblity of setting up a vacuum kiln for thick lumber (5” to 12”). The tecknology is out there for large operations but, the possibilty of converting large burl pieces from green to dry overnight is too tempting to pass up. Has anybody else attempted this? if so any hints would greatly be appreciated Thanks FordMike

Perhaps you are referring to a vacuum drying process rather than a kiln. Here’s a couple of links.

I just googled “vacuum wood drying”. Maybe this will be of some help.

Thanks, I have seen these and after burning too many brain cells. I think the thing to do is build a small version and try it out. Harbor freight has a vacuum “compressor” if thats the correct term, and I’ll convert and old pressure cooker to a chamber, probably need a liquid trap between, and give it a try, cant be any worse than Microwaving green turned bowls. I’ll take some digital of the project somebody will need a laugh. Thanks Again
