Well, I tried the cooling method discussed in the archives (still don't know
who made the post) for the GC. That is, hold a shop vac upto exhaust after
removing chaff collector, while GC runs its cooling process. I used a 3 HP
max shop vac bought at Walmart for this. Bottom Line: speeds up cooling,
especially at the higher temps, but still takes a total of ~ 9 minutes to
get to 140 degrees on GC temp display (~ ambient temp in reality). So, looks
like I will getting a hole saw and proper drill bits, and will be building a
5 gallon bean cooler next week.
