On the other end of that connecter there should be Flame Sensor, looks like a small dia. rod, may have a 45* bend in it, unscrew it and clean the yellow brown coating off of it with any abrasive.

The other way to make this is using perforated 4" dia tube as shown in the product page. 

Not sure what 12" miter you used that was underpowered, my 91 vintage Dewalt has cut 3" dia aluminum bar for me no problem.My belt is a 3x21 H-F that seems unkillable. it's an example of that H-F YMMV.

It took 2 applications to get it to hold and that was just a straight 50 ft, 8 in. dia. line with one elbow to the main drain.

We're interested in buy/hold/rent in areas with convenient car and/or bus commutes to Buckley AFB, the new Fitzsimons campus, DIA, and/or the redeveloped Lowry AFB.
