It shouldn't get too hot as the air is cooling it as it goes through. That said, I have had one of mine glowing slightly which I took to mean that the flame was inside the burner. I shut down and let the air cool things down and restarted. It was fine after that.

What do we use coal dust for?
Jim Kehler replied to BillyBones's topic in Solid Fuels: Coal, Coke, Charcoal, Wood, etc
I'm not sure if coal fines and coal dust would be the same thing , but that said, I have used coal fines mixed with water to a mortar like consistancy without any issues. -
I believe Brent Bailey uses or used shop air for his forge. A fancy regulator isn't needed, a regular gate valve as used for water piping would work fine.

Lee Sauder has a technique that should work well for you. I t should be findable on-line .

Power hammer help
Jim Kehler replied to Belfieldfarrier's topic in Power Hammers, Treadle Hammers, Olivers
Talk to John Nicholson at Massey, they are in the UK. That's the first Massey mechanical hammer I've seen. -
This sounds like a job for an Upset Forging Machine or "Upsetter". These come in sizes from 1/2" to 7". They are rated as to what size round bar they will put a rivet head on in one blow.

I've seen a Star, but not run one. I would think it would be similar to a Little Giant. Mine has 1 1/2 HP motor set up to turn the hammer at somewhere around 300 to 350 rpm.

Anyone have experience with polymer quenchants?
Jim Kehler replied to JNewman's topic in Heat Treating, general discussion
Hi John, it's been awhile but what I remember from using polymer quench was that it was messier than oil, I think most of the maintenance was from drag-out, and I didn't care for the smell. -

Using Flux As Decarburization Prevention?
Jim Kehler replied to Eric Morgan's topic in Heat Treating, general discussion
In his book; "the hand forged knife" Karl Schroen describes using a saturated borax solution to lightly coat his blades before heat treatment. -
That is very similar to what I have been using on my press for quite a few years, mine came off a truck with a hydraulic dump box.
