derrilex Ok it's all done bar the TO. Or I thought it was. Whats the go with these bloody motors ? Who else is using a power window motor and what are you powering it with ? I have a garden light tranny that is 48 watt / 4 amp and 2 more monsters that are 150 watt 12 amp and 220 watt 18 amp and it wont run on any of them yet it ran hooked up to a battery at the wreckers. Whats going on.

Whats going on. They draw high amps and about 5 amps should be OK They will burn out some power supplies if they are under spec Try a brick type normaly used on laptop computers as long as its 12 volt DC and a min of 5 amps A 12 volt DC x 2.5 amps will also work OK for short stints ( one roast) but it will also run at a slower RPM KK
Brett_H My 5amp brick came from Jaycar for around $30. I too had no luck with the light transformers.
derrilex I'm now thinking cheap ass battery charger from supercheap or similiar. I think most of those put out 5 amps and the better ones 8 amps
derrilex Hmmm, not so cheap. $40 for the cheapest battery charger. Crap.SOB.MotherF. Getting Pissed off now
derrilex Ok, now that last nights wine has cleared my system, its time for some more pics. The motor mount is a bit crude but effective. I butchered the window regulator to suit and inverted the motor to get more clearance. Slight height difference between the mounting surfaces of the motor cradle so I used 22mm timber on one side and 19 mm the other - again crude but effective. I welded a 1/4 drive socket to the gearbox sprocket after removing the gearbox from the motor. It all lines up great with about 3 mm clearance ( depth wise).
derrilex The base is just 18 mm MDF. I ran the router around to make the recess for the frypan legs. It fits perfectly and takes all the location hassles out of the equation. You can position it any way that suits, even move it around mid roast. I dont know if I will need any insulation on the top of the MDF. I'm sure heat from the TO will come down past the drive shaft and there is the frypan element there as well - see what happens
derrilex The agitator. I struggled with this for ages. I'm going with a 3 blade made from bits of whisk with a bent piece of metal at the base to try and keep the beans away from the centre. The blades work well but a few beans still get caught at the centre. I'll try it and see how it goes. Its ugly as but I'll judge it based on its function rather than its form :rofl:
Brett_H http://www.ehow.co.uk/how_6598014_build-12v-5a-power-supply.html 2nd hand ones at the computer markets are really cheap but as always after modification have it tested and assessed by a qualified AM! A laptop power supply 2nd hand would be really cheap and better for what you want. http://www.sundaycomputermarket.com.au/computer%20market.html
Koffee_Kosmo If you feel that 3 wire blades are going to fast and forcing the beans to spill over the edge just remove one loop Looking good so far :thumb: KK
Brett_H I used a 1/4" copper pipe that had the centre drilled out and the ends flanged out. I'll post a pic later.

Despite appearances it agitates the beans very well and because it is so malleable I could tweak it for best coverage. The SS wires are from an old rotisserie.
derrilex Ended up with the 12V 5 amp unit from jaycar. Got a cheapie fan, not a eco friendly one and a bucket.
Koffee_Kosmo Looking "fan"tastic :thumb: Roaster looks nice as well, perhaps its roast day tomorrow if the Turbo Oven is sourced KK
Brett_H Mate... seriously, it looks a bit too pro! Spot the builder eh: Galvo strapping... Is there nothing it can't do!!! :thumb:
Koffee_Kosmo Don't forget to make a video of the roaster I would also like to take a video of both roaster versions side by side Have to tee up a day for it KK
derrilex Totally out of my league KK. Pics are one thing, vids quite another but you are more than welcome to handicam up anytime you want. Hopefully my greens arrive tomorrow and I'll get the TO from Chris and all shall be well :thumb:
derrilex See if this link works http://s1174.photobucket.com/albums/r603/derrilex/roaster%20vid%20test/
