Air mod for oven

Post#1 » Sun Nov 30, 2014 11:47 am

This is the best air flow enhancer for me yet. Castings def improved. Very frustrating when I have been casting B9 resins for going on 2 yrs now. Large old oven was great, this small one is a pain in the a**. Here is a mod that is working.

Did drill holes near floor of oven (funnel is directed to one of them).

1 dollar plastic funnel, 10.00 fan from dollar general, one piece of string to tie the funnel on.

How many holes did you drill? Only on 1 side? Can we see a pic?

I think all he would have is one because most kilns have a hole in the top at least mine has along with the last two I have owned

I had drilled three approx. 1/2 inch holes on each side and this is blowing in the middle hole. Also enlarged the hole in the top a little. Have a grate in the bottom of expanded metal approx. 1 inch tall to set flask on.

Here are three more. Those large stainless nuts (laser welded together in twos) keep the grate from deforming when it gets annealed from all the heat.

Finally settled on foil tape at tubing and funnel barely gets warm even at 1400 f.
