4kw motor Conversion

Have a little battery saw for the small stuff now but the 390 still cuts most of our firewood.
Sorry, don't want to hijack the thread, looking forward to seeing how the redgum blades go. Ripping down the grain of hardwood is pretty demanding for a chainsaw, from memory I think there are specialist chains designed for the job that last a lot longer (and probably cost a lot more).

what's to prevent anyone from brazing a chain of the same cutting edge profile as any rip saw? seems to me it wouldn't cost any more than the traditional design.
chip evacuation with any chain saw is a serious problem. might be interesting to take a chain saw and just manually braze a piece of carbide from a skill saw on top of each tooth.

Well guy's a plasma cutter is my next job so I'm going to take my 6m plate in so I can make the frame for this 4Kw motor conversion, then I have to think about the slip rings. Years ago they used to use brass on brass so that's the way I'll go and for the wires I'll use 7x5mm copper wire to the connection to the slip rings and down the tower.
As I've said this won't have a tail as we are after the most current to charge the forklift batteries and as I wound this 4Kw for 24 volts 48 volts wasn't around so that is where I'll stay
Next August will be the time when this finally gets in the air but before I'm going to bury a couple of 40' containers and get some 1,000 AH forklift batteries to put in parallel for the storage.
Like i say with 3 lathe tests a peak of 90 amps at cutin is a huge thing to deal with and the name plate is 4Kw I'm sure it will produce it before the eddy currents come in to drop the current. Now I will make my own kill switch so I can shut it down.
I'm going to make my own place on virgin ground and get a 5 ton excavator I can do the ground work of burying to those containers so I can get a constant temp for my ferments.
Guy's with my trails the latest bottle I gave my boss he said it was the best whisky he tasted, now with the aspect of making my own grain on the farm I may be able to get that 18 hole golf course made and totally off the grid on 24 volts.
Cheers Bryan

sounds like a plan

Make sure you reinforce those containers! They will not withstand the pressure of being buried. They are strong on the corners and floor, walls and roof not so much!
