Topic: Heat gun specs (14 msgs / 240 lines)
1) From: Brian Kamnetz
I was looking at a Master Appliance HG-201A Heat Gun. You can vary the
heat, but not the air flow. When roasting coffee, how much of a
detriment is it to not be able to vary air flow?
Thanks,
Brian

I think it is no detriment to have a fixed airflow from the heat gun. If th=
e
price is right, the air flow is exactly right! Hallelujah.
You can always modulate the effects of the absolute temperature and air
blast by the way you hold the device and stir the beans.
This heat gun controls the power supply to the heat element instead of
controlling the airflow to control the temperature.

Brian,
    You CAN adjust the air flow on the Master Appliance HG-201A.

Blow me down- Now that I check, this is the exact model I was given about 25
years ago.
Ocean Pacific Images asked if I could fix one that was dead and two that
blew sparks-
They wanted them yesterday, and Grainger's had them in stock for ~$75 each.
That's all they wanted to hear! Suddenly they had no use for the cadavers.
"They're yours, Ray."
I think it cost me $40 or $50 total to fix all three of them. Then I gave
all three away to screen printer friends. I've seen the models that have a
power control knob for the heater power-  never had to work on it. Silly me-
I assumed that was the one. No airflow throttle plate, etc...
Pay no attention to the idiot that said the 201 controls power to the
heater- well, 3 steps, not continuous power control. Sorry for the misguided
advice.
Hope you get the one you're bidding on, but it'll probably go a lot higher-
Cheers -RayO, aka Opa!

Thanks, Ray. You were right, it went a little higher than I was hoping
for. But I am not in a hurry. I actually have a little Milwaukee heat
gun that I can use too if I want to; the problem is finding the time
to experiment.

Chaff doesn't seem to be detrimental to  heat guns, but you might try
stretching some nylon hosiery over the air intake

There is a heat gun with odd specs that I don't understand. The heat
gun is the Master Appliance Heat Gun HG-501A, which is said to have
1680 W, but produce temps only 300-500 F. Is this accurate? And how
easy would it be to roast with this heat gun?
Thanks,
Brian

the target roast temps (about 425 or so) and it would likely take too long
to get the beans roasted.  The low temp with high wattage indicates a LOT of
air flow, possibly too much to keep the beans from flying out of the bowl.

Brian, I had three of those 501's once, and I can't imagine the alleged
Fahrenheit temperature scale is correct.
I never used them for roasting, but I installed 1200 degree F, 1800 watt
heater elements from Grainger's parts depot in Chi-town. Then I saw that
Master rates the standard ones at 750 F max. at somewhat lower power. Screen
printers use them for flash curing @ 325F.
Brain donor employee types used them for hammers and broke them. Call Ray..
Yes, you can easily roast with it, unless it needs fixed. In that case, I'm
sure you won't be paying the ~ $90 new price. But fixing is easy.

I appreciate the input, Ray. I will put these back on the list of heat
guns to watch.

If you get a Master, Good! I saw a new 501 at Grainger's, and they're
warranted for Life! I think they're serially-numbered. Just ask the seller
if your particular heat gun will actually blow heat. Master probably makes
several other, similar, brands like Dayton.
Even if it is an oldie but runs, you'll find it to be a real workhorse. Just
take the brush caps off and check the brushes before you even turn it on.
Short, stubby brushes are not good for the commutator, even if it does run.
I would also recommend you put a tiny drop of oil in the felts that lube the
bearings, unless they look freshly-oiled.
Cheers and congrats -RayO, aka Opa!

Thanks for the tips, Ray. Of course, it's all Greek to me at this
point; If I land one of these, I may check with you again about
maintanance issues.
Doesn't have anything to do with coffee, but the summer (1981) that I
was working near Parachute I caught a performance by Emmylou Harris at
Red Rocks - can't imagine a better venue for Emmy, even though those
were the days of the Hot Band. Wish I could have caught her there when
she was backed up by the Nash Ramblers.

Brian, If you need help or have any questions, bring it on! Of course I'll
help.
These heat guns are pretty simple- that's what saved me! Magnum hair dryers,
in a way. The motor is quite similar to a drill motor- just not as big.

Did I say Kyle Anderson, Baratza Pres, is a Prince? He really is- sent
replacement parts for my SMP. That puts Solis and Baratza back on my list.
