wilesco d10/m66-little light output???? HELP

jakesm · wilesco d10/m66-little light output???? HELP

this is the system not producing any/much light

and another

any reasons why i am getting so little/no light output?

mamod · poor light

it looks as if the gear ratios are to low try a large drive good luck pj

I've had fun with the M66 dynamo and you need both power and rpm. Here's mine with a D14:

and here with a 1950s Mamod SE2:

You need a larger pulley on the flywheel end. If you mount the dynamo high up you may be able to run the belt around the flywheel itself. That might be going too far but it's worth a try.

Replacing the bulb with an LED should improve light output.

jakesm

so if i use a line shaft and feed the drive end over the biggest wheel and take the generator off the smallest wheel?

calypso

I think you need to drive the smallest wheel on the shaft to spin it fast, and then use the largest wheel on the shaft to drive the generator.

johnreid

You beed to make the most RPMs in order for a Generator to work well. a bigger wheel should drive the smaller wheel on the Generator 1 rev of the big wheel turns the small wheel more times. So the small wheel on the lineshaft is driven by the engine and the bigger wheel on the lineshaft drives the generator. It makes sense once you think it out.

For best results drive the genny right from the flywheel pulley ...no lineshaft.

Use largest flywheel axle pulley possible. Your pulley is a single and too small...you need the next size up.

My M66 use should be search able in the video section here.... I run Trains with mine ! it makes plenty of power with a D-20.

Is the bulb factory?...

I can get the specs if you need em...I think it was 6 Volt 60 MAH....

thanks one & all for the input! i think i might have it now

Minor1PJG

I have tried with lineshafts to use gearing but I found that the drive bands slipped. If I made them tight enough to stop slipage then I had put too much additional load on the engine

It's good fun experimenting though

jakesm

the consensus then, putting one of these on line does not help??

Minor1PJG

It didn't work for me

If you have one, give it a try

Wallace

If you have oring material (nitrile rubber???) use that as drive bands as it will not slip without needing to be too tight.

There is also green stuff. I don't know the name of it, but some members use it, and that's even better again

johnreid

THe lineshaft is an easy way to change the rpms, so I cant say it always hurts as it depends on the pulley sizes used.

Meths

Like Jim / Metalhead100 says though - first thing which is easiest to check is the bulb. Make sure it's a 6v one, not a 12v or 24v which will give you a dim output. Do this before spending time and money on pulleys and countershafts.
