Re: So it begins... home-made drum roaster
OK, heres MkII. I made it bigger, and it can handle 200g of beans easily.
The tube is 150mm long now. Taco, you will note that this time I pop-riveted the blind end. I fitted a vane inside for turning the beans over.
I had to make the frame longer to accommodate the longer tube. I buy the 5/16 whitworth threaded rod & nuts from Bunnings, and cut to length. I clean up the ends with a linisher, but of course you can use a file.
I used pop rivets because I could see the thing becoming rattly if I used screws and nuts, especially with the heating/cooling. The bayonet I made with my Dremel and a file. You can do anything if you have a Dremel! You can see a spare hole or two in the open end of the tube. Thats where I stuffed up the position of the screws for the bayonet.
