It's quite sturdy. Also visible is the mechanical relay. I am not sure how long it will last, but i like to hear the click and watch it moving. Its like electricity you can see! http://www.cellbots.com/wp-content/uploads/2010/08/standoff_detail.jpeg The only thing I still want to do is mill some heat sink slots in the bottom to reduce the thermal mass and make the fan more effective.

One question - with your stainless finish washers installed the way I think they are installed, how do you keep the standoffs from sliding out of position? Maybe I'm missing something. Do you have any pictures of the standoffs showing the assembly? Nice work, the fan is a nice touch too! Wow, very nice!

Thanks for posting, it gives much more consistent results then the hot air gun. It is 4x6" and has two 300w cartage heaters. I used thicker 3/8* ceramic standoffs so I fixed the thermal transfer problem by using stainless finish washers, the very thin cupped kind, on the top and bottom of the standoffs. The base dose not even get warm. I bent a base out of steel and put all the electronics in there along with a fan to speed cool-down. Without the fan it stays burning hot for hours! http://www.cellbots.com/wp-content/uploads/2010/08/IMG_20100804_173033.jpg I have built a hotplate based on your design and it works great!

I have a fully funktional temperature controller using a love control which was made just for this type of applications and there has never been a problem of overheating. It could be kept on all day with or without a load on the heater block itself and would never over heat. I can take some pictures of the inside wireing if you would like. Nice job on the heater block by the way. Plastic teflon is a very good heat insulator and can handle very high temps. To the person making the hot plate controller.
