Hi Frosty,
I'm from north-central BC in Canada, so not likely anyone in visiting range . As for your questions, after melting out the crayons I used a drill bit by hand and reamed each hole until i felt the bit bottom out on the back of the metal inducer block, so the holes themselves should be clear. I then did this again after coating the face with TIC-100 to make sure that none of that had dripped into the holes creating a plug. The block is held in by 4 set screws though, so its very easy to remove and confirm. I'll do that later today. For my set up I have a Hi-PSI regulator running off a 100lb propane tank, with a 3/8ths line run to the forge, which tapers down to the MIG tip that is used as the jet in the T inducer. As I said, I copied your final dimensions exactly as far as I know. Even when running full open on the regulator, the best I get is a light orange heat, not quite yellow. Is this typical of propane or should I be able to do better than that? I'll post a bunch of pics, perhaps that will help. Also, this issue is happening as full open, so there is no more pressure fuel i can add. When it is first warming up, the flames lift off the block at full throttle, but once the forge is up to heat, they are maybe 1 inch blue flames sitting nicely on the block at full throttle. Thanks again!
