Eureka! 2 pounds of Mocha Kadir at 500 degrees. 1st crack at 11m30s, cut back to 480 - second crack at 14m - finish roast with a nice Full City + at 15m 30 sec. - no signs of divots. Thanks for the suggestions. It does baffle me though. It seems that everything I read on the subject suggested that somewhere in the process I was too hot and that was what caused the divots - some suggested too fast into 1st crack - others suggested too hot (therefore too fast) going from 1st to 2nd. Whatever it is, this seems like a nice profile.
Thanks again Shane.
I can't tell you how pleased I am with the new drum/motor combo you sent me. Installation took about 45 minutes and after that I was up and running. I've got the Charbroil Quickset grill (35k) and installed the big thermometer from Home Depot.
My grill seems to like 480 degrees so here's what I've been doing:
Preheat to 500 degrees
Put 1 lb beans in the drum while
Quickly put the drum in the grill and get it back up to 480 asap (within 1 to 2 minutes)
1st crack happens around 11-12 minutes
2nd crack is right around 15-16 minutes
This makes a really nice City+ roast and since I've gotten the timing down I've put about 10 pounds through it in the first few days. Each batch has come out the perfectly the same.
Thank you again for making such a great product and if I keep roasting like this I'll be back with you shortly for your bigger motor!
P.S. Thank you also for the extra collars...I've got them in a safe place for if/when I need them!
P.P.S. One design enhancement you might consider - The retaining pin that holds the drum closed has a small washer attached to a chain. If you could solder that washer in place (or just attach the pin directly to the chain) it would stay out of the way. I've been using needle nose pliers as you suggested which helps, but that washer does get in the way and can hamper the pin removal.
I'm an engineer--the drum is a work of art and the motor and mounts are terrific and the whole kit is well thought-out and it makes GREAT COFFEE! I've done several roasts using your suggested profile for 1lb batches and I'm getting the hang of it! I will graduate to larger batches when I decide what kind of beans I want to order in quantity. The only bad thin.g about this setup is that I want to roast all the time and you need lots of beans in your inventory to have all that fun!
Thanks for your great products, and even more for your superb customer service! Keep up the good work
Just finished roasting a 9 lb batch of Nicaragua Dipilto... It was flawless!!!! Thx again!!!
Only 31 pounds to go;)
The roast is perfectly even throughout the entire batch... Fabulous!
My first 5lb roast was all over the place, but I leveled the drum (not the BBQ), and it came out perfect
Shane-- drum is working great, developing a very nice patina, if you will. 7 roastings so far, fantastic flavor which to me is fuller than the fluid air bed roasts. I am getting to 2nd crack at about 12 minutes. I'd like to slow it down slightly but that's a good time in my book.
