Convert 1975 Afron Cherrypicker?

The Mars motors are around 200mm in diameter, and have threaded bolt holes on the face (where the shaft comes out). I would probably keep the universal joint, cut the shaft short, and weld a coupling for the motor shaft in the end (motor mounted somewhere close to the picture above) The price is a b...

Convert 1975 Afron Cherrypicker?

the improvement in control gained by the electric conversion will make the machine much nicer to use though.

It doesn't sound like it'll be doing massive distances, so it'd be easy enough to tow it back or recharge if the batteries went flat (generator on a ute or wheelbarrow?)

Convert 1975 Afron Cherrypicker?

I think the 100A controller would be ok. The Mars motor is only really rated for 100A continuous anyway. I haven't personally tried that controller, but given the low gearing you have I don't think there'll be too much load on the motors. It might be worth checking that the controller is ok driving ...

The speedo pickup would also detect holes, so you could just use your park brake disc for both purposes.

Convert 1975 Afron Cherrypicker?

I'll have a look later for Mars / Sevcon availability. I bought mine from a robot parts shop :) There are one or two around on this forum I think. It's easy enough to make a throttle lever with direction switching so it'll work with normal skid steer style controls. I have a sevcon programmer I coul...

Convert 1975 Afron Cherrypicker?

yeah I think two motors for drive and one to run the hydraulics would be the best bet (maybe replace the pump with an integrated electric pump as used in small electric fork lifts, etc) 2kw on each wheel would probably do the job for the current speed - but I think you'd want a bit more power for re...

Convert 1975 Afron Cherrypicker?

It'd be good to have some measurements of the input rpm to the gearboxes, or the tyre diameter and gear ratio, but I imagine you could put something like a Mars motor, ADC 6", or similar on each wheel. You'd need a controller for each motor, and they need reverse - so the Mars brushless and Kelly or...

Mercedes 190D donor car

I have a 1987 Mercedes 190D that I need to sell. It's a similar car to the BMW E30 series, but has a nicer suspension setup. This one is diesel, so it has a very heavy drive train to remove :) It's running (and currently registered) but the engine is pretty tired and the transmission has minor issue...

the content percentage is probably based on the dollar value of the parts.

ie the "glider" costs about 20% of the finished car.

Weber and Coulomb's MX-5

a convertible is never going to be engineering perfection :P

Getting an MX5 anywhere near the rigidity of a similar sized car with a roof ends up being substantially heavier.

even if the shocks go vertical, you could just have a small cutout in your battery pack area for them.
Are you putting batteries behind the diff too?

Outboard Motor conversion

the sustained power requirement for a boat doing ~10knots is very high. It is possible to get pretty good cruising speed with very little power if you use something like the hulls from a small sailing catamaran. They're pretty cheap if the sails, etc are missing or damaged. Something like a Hobie 18...

I would definitely go for less bars, and as straight as possible - for rigidity without adding too much weight.

Even if the structural frame is very simple and triangulated you can add some non structural / semi structural bars to mount bodywork and parts on.

if one is shorter though, it will move through a smaller radius, so will effectively change length more.
Also, if they're on the same plane they may as well be the same bar :P

Various Nissans have a rear caliper with hand brake built in.
I probably have a pair you could have. They seem to multiply in storage!

I think it makes more sense to do it in the normal way with the pivot on the diff, for strength and space reasons - and simpler frame requirements - but it'll certainly work either way.

EV2Go's - Lithium Powered Trike

yeah I think you're right about the pin. It wouldn't last long before wearing and becoming a bit loose I think.

Best bet would be the "normal" design where the arms connect above and below the central pivot point.

EV2Go's - Lithium Powered Trike

I don't think it needs to be adjustable.

It would be easier to make it strong if you have the centre pivot section on the diff I think, and the arms can run out to the frame on either side.
You could finalise the mounting points on the frame once you have checked the ride height.
