Heat bed construction pics

I was building a second heat bed and figured I would share some pics of the steps and process. Waiting on delivery of the actual heat pad but here’s the insulation/water barrier and rough framing. Will add the the steps that follow when the material arrives. I believe I shared the original one I made with the modifications in year 2.

Let me try this again, there was a replan. Sorry for the random order of the pictures, remembering to take them was a big challenge!
