I'm watching this too. I need a better way to dry wood. I'm getting too old to wait around for it.

Google it, there are quite a few blog posts and articles on the internet. I think for an upright freezer a 100W incandescent bulb provides enough heat output, but can't remember too much about the other details.

Tony, There is a short article about converting a freezer into a kiln in a past issue of the American Woodturner. I will post a link below, but I am not sure if you have to be logged into the AAW website to read it. Give it a try... and let me know how it works.

Everything I've read and heard is start with lower heat than you think you should and raise it slowly. That may be the reason I have procrastinated on building any type of kiln. I don't like to wait. I'm an "If a little is good, more is better" kind of person.

Thanks for that link Matt. That about as simple as any directions I've seen!

I posted this on FB, but since you asked, here it is again:

Just take an upright freezer and gut it. What you NEED to do is put a light fixture (simple ceramic $2 version is fine) in the bottom, run electricity to it with a switch, drill holes in side at the bottom (to let air in) and holes in the top or on the side at the top (to let air out)...I did six 5/8" holes in each location.

To run the unit, insert a 25 watt bulb for a week, then a 50 watt bulb for a week, then a 75 watt bulb for a week, then a 100 watt bulb for a week. It is basically an Easy Bake Oven. And that is the minimum for what you NEED to do.

Now, I don't do minimum, because minimum means more work for me in the long run. So.... instead of a normal switch, I installed a dimmer switch. I like the kind that has 5 steps (the bottom one being 'off', and the other 4 are incrementally higher wattage...I like to believe they are 25%, 50%, 75%, and 100% ;) ), and put a 100 watt bulb in. That way, I don't have to continuously change bulbs. Also, my freezers both came with fans. So, I ran power to the fans, and put a switch on it. You don't want the fan connected to your bulb switch because then it wouldn't run at 100% all the time...not sure if that is good for the fan...or effective. The other thing I did was to cut a 'window' in the front. I did that for two reasons. I can see if the bulb has either burned out, or turned off due to a very short power outage/surge, and so I can read my thermometer/hydrometer that I installed right behind the plexiglas. On the model in the pics, I put only one layer of plexiglas on the kiln (on the outside). On my second one, I put a layer on the inside, too (two layers). The reason is that with only one layer, you get condensation on plexiglas, and it drips down the door, and creates puddles on the floor.

Keep your eyes pealed on CL...people sell freezers for free-$50 all the time.
Hope that helps. And feel free to ask any questions.
