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.
It's been a week since I received and put together my new 6Lb DIY combo and in short, I'm thrilled! I had a few small challenges with the installation but engineering the solutions was part of the fun.
With this 10 year old Weber grill, the square tubes were about 3/4 inch too low for the base plate-motor mount combo at the highest position so I cut a pair of 1x2 shims to sit between the base plate and the tubes and got some 3-inch bolts for the muffler clamps--just right! The rotisserie cutouts in this grill were tiny and wanting to avoid using the Charbroil mounting brackets, I used my Dremel to cut those slots in the grill deep enough to accomodate some extra bearing-bushings that I bought at a grill parts supplier. Now the rotisserie spit is strongly supported on each side of the grill and I think it makes the motor's job easier since the spit and drum aren't hanging on the coupler. By the way, the motor , motor mount and baseplate is very well made and I especially appreciate the holes being pre-threaded for the electrical boxes. I chose to mount an unswitched duplex outlet on the back position to give me a place to conveniently plug in a fan to blow on the motor when I start doing big long roast sessions. To make the grill more efficient on gas, I blocked off about 70% of the rear vent with a piece of carpet threshold that fit perfectly and already had a slight bend which makes it press against the grill base nicely when the hood is closed.
Enough tech-stuff--forgive me, 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 thing 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! The picture attached is Guatemala--Villa Herminia at a very even roast...delicious.
Thanks for your great products, and even more for your superb customer service! Keep up the good work!
I received the Drum and Motor setup on Thursday, I had
to make a few adjustments to get it level and in line
on my Weber grill, took about 10 minutes and then let
the drum burn in for about 15 minutes.
Today (Saturday) I did two roasts, the first roast was
a little over done but the second roast came out very
nice. Each roast was 1 pound. It is going to take
some practice with roast times and getting the drum
into the grill without losing too much heat and
getting the beans into the cooling tray but I think
after 3 or 4 roasts I should have it down.
The motor is very quiet and I have no problem hearing
the first crack.
I am pleased with the drum and motor and look forward
to many roasts, you have a great product.
Hey Shane-- just did my 50th roast last night. I am really excited about the outcome. The 1 and 2 lb roasts go a little fast, since my grill puts out a lot of heat. But the 5 pounds are going about 15-17 minutes and the flavor is fantastic. Great product.
Wow, thanks for the amazing drum. It's so strange to
me to go from an inconsistent 1/2 pound of dog-bowl
roasted beans to 2 lbs of a consistent roast!
Since I manage a BBQ store, I was thinking I'd serve
free coffee samples on the weekends. I'm just gonna
brew a pot or 2 and put out some 4/6oz cups. I would
really like to show people that I roasted on a BBQ, so
how do you feel about supplying me with either
business cards or flyers if you have them? Or if you
just sent me a p.o.p. 4x6 or 8x11 I'll just put it in
a plexi stand!
Let me know if you need parts/supplies

to mount in the center of grill hood!
