with the floor bottom in place, I cut a duplicate on the table for the top of the floor bottom. Before I attached it I added insulation. One layer of insulation suited to handle up to 1200°. That’s about 3 inches thick and 1 inch of 2000° insulation
With the oven bottom done, I set the walls back in place and pre-clamp everything
Time to attach the walls. These are the thin sheet metal studs so anchoring them to the floor, which is now 16 gauge plus the thickness of the studs as well, is a weak connection. I decided to add sandwich plates
The drill head is quite remarkable. An air cylinder pushes the drill quill down, so that is lower than the torch head and then the Z axis lowers until Z0 and drills the depth of the cut. The accuracy is solid
With the holes drilled, the air cylinders released the spindle raises, and now the torch becomes the primary tool.
Here is an anchor/sandwich plate and one installed right behind it.
These plates are used in every location where the walls meet the floor. 44 rivets total
Hard to imagine I can spend so much time and make what appears to be so little progress.
That said, I have most of the ceiling done and I’m waiting on a few parts so that I can assemble it.
I did go downstairs and pull the temperature controller off the shelf and bring it out to the shop. It’s a nice little unit that I bought on Amazon when I stumbled across a 30% off deal.
