I kinda inherited this. The club member whose shop we have been cleaning out built this and one for a friend (twice this size). So last thing to haul off and I am going to try it out. The friend he built the larger one for showed me some 2x2 blanks he dried from soaking wet and not a crack. It has holes drilled top and bottom and a incandescent bulb for heat.  Uses a computer fan to circulate air. The thermostat is set to low of 90 and high of 100 but as I set this up noticed the thermostat is in Celsius so go to internet and get 32.22 to 37.78 ok I used 32 to 38.  Will test this in November when I get back from the Lake.

 

Incredible idea.  

Cool! Anxious to see how it works for you 

Might be a winner.  Any idea how long it takes?

Nice score. Lots of people are using such setups so they must work pretty well.

I’ve seen people build the larger ones out of plywood and styrofoam but that is a really cool idea. Ready made and simple. I wonder if you could adapt that concept to a chest freezer for small batches of lumber ?

There are bunches of the chest freezers on CL for cheap. Thanks for the post Gerald ! Now if I only had room for one.

Not sure on this as I did not ask Sammy, but I think less than 2 weeks.

I see no reason it would not work with any refrigerator or freezer. Woodturners do not usually think in larger terms of dimensional lumber but I have seen some larger than a regular refrigerator. Just need (I think) top and very low bottom or side holes. 

The little one I made, from Rick Turns video using the same hardware, dries a rough turned blank that has been soaking in soap and water for several days in about 10 days. Haven’t lost a blank, yet.
