Hey everybody, I’ve been busy the past two weeks! I had a great time at Playlist Live, and finished some much needed organization in my garage. I finally got around to building a large kiln to help me make investment molds for aluminum casting. Now I can finally get this laser gun built!

I couldn't find any info on any projects like this, so I thought I would have a try myself. I thought an oven would be the perfect platform, it already has a door, space for insulation, and comes with heating elements!

The oven was almost exactly $270 to build, which is about $200 cheaper than a used kiln on craigslist. and 1/10 the cost of a new kiln. I could only get it to 820c - 1500f, Real kilns can get to 2300f. I think my kiln could get that hot if I wound my own heating elements with nichrome wire and added another layer of insulation.
