[Jeff Davis]

Hi Ron,


> 1.  Is that a used water heater?  Hard to take the top off?  Double wall
> with insulation?


Yes, it was a used NG hot water heater. Easy to remove top. Unscrew sheet
metal top. Tourch around flue and torch top off leaving about 1" lip. Yes
I kept the outer housing so it is double walled.





> 2.  Looks like you used a blower.  Have you tried natural draft with same
> geometry?

Yes, I use a blower. No I have not tried natural draft, this works good
and I have so little time.


> 3.  Would you recommend tipping the char out and then watering - or
> watering
> the char in place?


I water then tip out because this device get VERY HOT!!!!!!


Someday I'll design one with trip grates and bottom clean out. Plus I need
it to heat my buildings in the winter time plus make charcoal. That's a
must.



Best wishes,

Jeff
