Hi All,
Finally got myself into gear and made a home roaster. Been meaning to for a while but the poppers been doing a good job and there wasnt too much incentive to change. However, the popper popped so I was roasterless.
Heres what I started with:
* Stainless Steel mixing bowl. Flat bottom and curved sides. ~$5
* 70rpm 2.1 kg-m motor $20
* Motor shaft adaptor $5
* 12 VDC adapter $20
* Mounting bracket (l shape) $1
* Double ended bench vice $15
* Hot air gun (free! already owned)
* Stainless steel teabag squeezer $3
* block of wood...
So the general idea was to drill a hole through the bottom of the bowl, mount the motor through it and attach to a mounting bracket, throw the heat gun on top and see how it turned out.
The hardest part ended up being the mixing blade. I ended up using half a teabag squeezer for that since the metal was fairly flexible and allowed me to twist into shape and get a good mix going.
Attached is a pic of the setup. The first roast turned out very nice indeed. Ill be enjoying it on a Gaggia Evolution until this weekend when I pick up my Silvia!
If anyone out there is interested in doing something similar and needs help, give me a yell. Not a bad result for $70 I think
Cheers,
Pete
