In Topic: Adding Vent To Older Kiln...

The blower is quite oversized. I believe the standard envirovent blower is
135 CFM. This one is 240 CFM inline off of eBay.. I didn't know how much I would need in my crude
home brew version. It was not much more expensive to get a larger one.
Also, the six-inch was the smallest I could find that had metal fan blades
versus plastic. I was worried about the heat melting the plastic blades but
the exhaust turns out to be no place near that hot. There is enough leakage
to cool the hot kiln gas. I use the rheostat all the time. It is just one
of the standard rheostats used to control incandescent house lights.

The one thing I would do different is to take center tube, connecting the
blower to the vent duct, down to a sheet metal shop to get the other end
crimped. You can't buy those straight tubes crimped both ends. By far the
hardest part was hand crimping the uncrimped end.

Let me know if you have any other questions

Thanks for your positive comments. Inventiveness springs from being lazy and cheap :)

I built my own envirovent for my Skutt km. 1227 for about $40. It works very well and is easy to build.  Here is a picture of kit. It just slides under the kiln and is held in place by a small flat spring. If you have any questions just let me know.

A drafting pen with iron oxide works pretty well on the bottom of bisqueware.

I have tried that both by hand and with my belt sander. The bottoms aren't bad. They're probably about like attila the Huns gluteus maximus after riding 1000 miles.. Nothing you'd want to show off.
