Need this about as much as a hole in the head but I'm pretty sure you're supposed to have fun in retirement and these goofy projects keep me entertained. I don't know what the basic closure was made for. Looks like it could have been a mounting bracket for an electric trolling motor. So I added a back piece, a bottom and hinged a cover for the front out of scrap aluminum. Bottom is only 1/8" aluminum so may have to go heavier on that later on. Seems to be OK on initial tryout with a cheap 1/8" TC inserted into the side. Also made a couple different gizmos so the mould's sit flat on the bottom.
Next step is to use one of those little threaded TC's and tap the bottom plate for it. Can watch the temperatures on the other probe with the multimeter and keep an eye on the PID while it's tuning. Did seem like the AT went a long time getting done on the first go round. That picture ain't great but believe I shot 30 of em' to get this. Flashes or bare light bulbs don't seem to be compatible with brushed aluminum!
