Topic: Hot Rod Home Coffee Roasters: The Spirit of Invention, (2 msgs / 94 lines)
1) From: Edward Bourgeois
http://www.sweetmarias.com/homemade-homeroasters.phpThe world of roasters has changed in the mere 6 year since I started.
I contend that how many think about roasters and roasting has changed
also.
When I started there wasn't much for off the shelf roasters compared
to now.  There was a lot of new DIY builds and modifying what did
exist like MiKe's
modified Rosto setup. The conversations were much around how  beans
needed to be treated during roasting, what sort of control was
helpful,  the fundamentals of various approaches, etc.
Now it seems discussions are around P choices, roaster work-arounds
and when is there going to be a cheap 120v true 1lber and with no
needs for work-arounds on the market.
I get numerous requests of either, will you build me a Dreamroast? Or
do you think I could build one? I answer no to the first thanks to a
talking to by my lawyer friend and I just don't know how to answer the
second.
In the past, it seemed that folks would study up on roastering and
bean fundamentals, work up a plan, give it a go and ask for advice as
questions/problems arose. I named my roaster the Dreamroast because it
took me a year+ to come up with a design and sort through piles to
junk to find parts for the build. I'd do my thinking at night and
often wake up in the morning with ideas that I couldn't remember
whether they came to mind while I was still awake or in a dreams. Thus
it's my Dreamroaster.
I'm not saying our "spirit of invention" is gone but I do wonder if it
has changed from the purity of purpose and can do attitude it once
was.
My guess is the elusive off the shelf, highly controllable, 1lber, for
cheap many desire, though possible, will not come to market anytime
soon.  Maybe it's time to rekindle the spirit of DIY invention and
that can do attitude.

This insurance trap is real, I admit. It is stifling innovation across the
board. Nobody will take risk because there are droves of unemployed
attorneys (200K+) hungry to sue anybody. The system encourages it. Enact
"loser pays" legislation and most of this will stop. America, the land of
innovation, will come back from the brink. I see the high level of fear in
all kinds of businesses today and the way they interact with their
customers. Excessive fear of litigation, another ailment grinding our
economy to a halt.
As for the 1lb roaster, I think the QM3 could easily do it with a little
improvement. I insulated my drum heavily and it has no problem doing 300g. A
little more mass and power, with insulation, and slightly larger (say 20%),
and I think it could handle 450g roasts on a 15A circuit (dedicated
preferably). Perhaps a small hose taking exhaust heat and recirculating it
back into the intake would get the heat up to 1lb requirements. I love the
Q.

The cost to consumer is driven by the development costs and the
liability insurance costs. The 1-2Kg roaster that could sell for 500-750
will be more like 4500-4750 and up due to these costs. No liability
insurance company will provide coverage for an untested, brand new
design device that is capable of taking 2 to 4 lb of a highly
combustible material to 500F in less than 10 minutes with a forced or
induced draft. You would have better luck if you installed an automatic
50lb CO2 fire suppression system on it but not much.
Depending on where you live even buying a homeowners policy that
includes fire insurance is very difficult if you have a solid fuel
appliance in the building.
