Re: little generator
You can make your own metal discs from a soda can or even better from a sheet of brass, about .15mm thick. Brass gives you more runs, compared to Aluminium, before you have to replace the disc with a new one.
The RJL heads are much better though, then there are none of those silly disc to worry about...
For diesel fuel you can use Tygon or neoprene tubing, both are easily available on ebay for instance.

Re: little generator
okey
i have disasembled the generator
the tubes were not broken
there was a clog in the spraybar
and the knoking i heard was the piston that had to be reset
there is also a little tear in my last teflon head
it is not all the way trough
so i have to place a order with berty

Re: little generator
it is running again
it needs a little more fuel then bevevore so the little tear is notisable
i am gonna look for a load and test it with a load
just running it gives me 16-28V
and that is a rpm regulated voltage
pritty nice actualy

Re: little generator
it get easyer and easyer to start the engine
i think i am getting the hang of little diesels
now to find normal lampoil
the one i have right now has anty smoke stuff added to it
and that burns my eyes

Re: little generator
i have done screwed it
i ruinid my last teflon disk
i was cleaning the engine (i like to clean engines when bored)
and the disk broke when i took it out
luckaly i ordered 2 last week
(i hope there here soon)
i am also gonna do a nitro test soon
i could not get it to run on nitro bevore
i think this was becaus of the double reed

Re: little generator
i have been thinking of building a second generator
but i want it as small as i can posably build it
so i have chosen a recoil started car engine

Re: little generator
i have another great idea
i am also gonna make plans for a 3th one
but that one is gonna be crazy
becaus i am gonna convert a cox into petrol
and design the generator around that

Re: little generator
but there is but a few bugs left
i need a better flywheel
the crankcase would be better if it were a pusher
and the screws on the coppeling peace keep losening up
but for its good enough

Re: little generator
That turned out really nice! Sounds like its running well too. What do you get out of it? 25vdc? Have you tried putting a load on it yet? I wonder what the max output is (watts). Great Job
Re: little generator
Wow! That really did come together nicely.
Thanks for posting the video.

Re: little generator
Sweet project! That looks really nice. I've heard others mention this, I started something similar but am not sure what accessory I want it to run just yet, but I'd like to try it with a small belt and pulley system. Trying to keep everything billet aluminum.

Re: little generator
i would suggest not to use belts or pulies
thay make the project only more dificult

Re: little generator
The elect motor acts like a flywheel too, you are all set now measure voltage and amps and feed the generator to a source such as a 12v light. Show them what your (generator) can do wtg!! You may find you need more rpm to get the voltage up more flywheel weight will just wear out the .049 faster. Also don't forget to oil the front bushing from time to time on the elect motor.

Re: little generator
i am planning on building a variable dummy load
so that i can load it down till it shutsoff
and then i know the max amperage on the generator itself (it putsout around 18-30V)
and after that with a buck converter so that i get a constant 12V
if my buck converter isnt powerfull enough i will be amazed (its 5A max)
i will drive everything to there limet
btw i just rebuild the engine
i replaced the backplate so that i can mound a chock tube
this makes starting more easy
and i can add a carb if i need to

Re: little generator
i still have no readings from the generator
but i do know
i hate the diecast sure start backplates
they do not work as good as the original does on my generator
and also the aluminium disks wont work
and starting was harder
so i remounted the original
sad that the dirt cover was damaged (and lost)
and now it runs again
