Hi again.

I used a circular saw and a 7" metal cutting disk (~$2) to cut the square tubing. But now that I think about it, I could have bought the square tube already cut and made of stainless (even better). I did a quote and the square frame already cut and made of stainless came to be:

http://www.metalsdepot.com/

2x2' 1 X 1 X 16 GA. (.062 wall) 304 Stainless Steel Square Tube = $22.60
3x1'1" 1 X 1 X 16 GA. (.062 wall) 304 Stainless Steel Square Tube = $24.12
Total $46.72 + shipping

(There are other metal companies. Example: http://www.cut2sizemetals.com/ )

Basically , if I were to do things again and order the pieces cut, all I would need is a drill (a drill press is better).To mark the holes for drilling in the handle area, lay the oven upside down (without lid) in a squared floor.

I'll look into adding plastic square caps to plug the square tube and get also 2 elbow (90 degree) grease fittings for the bearings. May look into painting since this frame is not stainless.

While looking at the previous picture, I realized I could save metal by changing the orientation of the axes. It helps too post pictures sometimes to get better ideas.

This is how it is looking (unfinished). Today I'll do a little bit more

It is done!

Looks really good. The motor and everything works. It is painted black (frame). Will put pics tomorrow but I don't know when I'll have time to do my first roast to check out the performance.

PS: Haven't done the exhaust fitting or the "cyclone" (metal pot with stainless colander attached to vacuum) but that is small game.

Cheers

Very nice Arpi, looking forward to the pics and the roast results.

It runs smooth









Cheers

Rafael, seems like it is time for another Baltimore meet-up to see the roaster in action!

Hey Sweaner. Maybe there will be one in the future. The roaster only weights 27 pounds and is portable

I did a quick roast today and it was a success. Loud first crack ~ 7-8 minutes at first roast with probably not a fully warm up roaster. Had a thermocouple through the lip over and dropped the beans at 400F. As it is right now, I can control the temperature just with the gas burner. No need for air holes though I don't see why not do one. The temperature just keeps climbing and climbing (+550F) which is good as I was concerned it did not have enough power. If I bring the gas down, the temp goes down (OK response). I used a full tall glass of beans and was surprise not much smoke came out except for a little trickle. I am not sure why not? The roaster is stable and hard to tip over. So, everything good so far.

The bearings got a little hot to the touch (probably low 100F or lower) but the instructions say that they take + 200Fs. It was most probably caused by the radiated heat, not the shaft. A blocking shield should keep them cool. The manufacturer recommends to lube them once a week at that temp range (+200F) if used everyday, otherwise once every 6 months. The frame was not hot and I was able to flip the roaster and dump the beans in a big bowl. My next move will be to make me a cyclone to extract the beans without flipping over the roaster

I also live in baltimore and have a home roasting setup. Nice job putting those pieces together. I'd like to meetup and compare notes and thoughts on roasters.

If you are going to use a cyclone, try the dust duputy from oneida, they totally work. I am using one to suck up chaff after the roasting process on my Hottop, and everything goes into the lower bucket instead of the vacuum. Once in a while, I dump the bucket, no big deal.

I am working on a better cooling system too. I use a colander and a vacuum, and I've been trying out a screen basket as well. The beans need to be stirred while cool air flows through them for the best effect.

Can you take a video of your roaster in action? I'm not realizing how the basket is loaded and dumped.

Hi.

I could take a video on the weekend.

This is what I am planning to use as a "cyclone" (not really a cyclone). Make a hole on the top section and another on the bottom. Stick input-output hoses (vacuum) and done Stainless steel too + glass. It should pull the beans out and cool them too.
