I spent this morning getting the metal removed on the back of the garage where the old window used to be and adding some missing purlins and a couple that had rotted under the window. While I had the metal off, I cut the hole for the room vent and got it installed. It was a bit long, so had to fir out the location.
I may replace the light switch that I have the room vent on with a smart switch, and setup a temp sensor in the room to kick it on automatically over a certain temp.
I then moved on to the kiln vent. I had planned to put it in the corner behind the kiln, but must have had some brain fog and ended up cutting the hole 2' off from where I had planned, which was to the left of the blue line on the wall.
I barely missed the electrical box for the kiln (which the breaker was off for), but did nick it's cover plate.
After contemplating my options I decided to go with this location, I just trimmed wall thimble plate around the electrical box.
It turned out to be a good location, since the electrical for the blower is just above this location, and the cord I used to wire it with was just the right length, which it was too short for the place I was going to put it. Yeah, now that I think about it, I planned it that way...yeah, that's the ticket.
Had to trim down the outside plate for the thimble as well. not sure I really needed it as big as I left it, but oh well.
The blower is rated at 140 cfm, which is what googling says the Skutt kiln vent uses. I'm using the Skutt Envirovent cup at the bottom of the kiln, Just need to finish sanding the top and bottom slabs, then drill the holes for the vent after re-installing them.
I have about $310 in the kiln vent. The blower/motor, 3" dryer vent, wall thimble, duct, and 3" flange cost me about $210, the Skutt vent cup, spring, and foot for it was $98. The full kits are available from pottery supply, but sell for $650 - $700, depending on where you buy it from and they provide "free" shipping.
