Gilmer project - complete re build going electric

Post by Dirt car »

Hi All

I have seen Scale Gilmer and working Gilmer but not both in same car.

I was part way through my Gilmer project after putting it to one side 4 years ago. I had fitted a Saito twin and a rear axle differential (but cant recall where it was from) and home made clutch. But there were too many things not going right - so I abandoned the project and have just come back to it.
Im now going for electric power I want the car to look as scale as possible but also run.

This is how it originally arrived from Gilmer to my home in the UK 6 years ago

Thanks
Just thought Id add, Im not going for speed, more a good looking Gilmer that actually moves and steers and makes the right noises under its own power.
I could have got a 1/5 size motor but it wouldn't fit without compromising the looks.

I fitted mine with a nitro 60 and a 90 degree transfer case with the clutch system from an rc helicopter and sprocket and chain. I copied Jan Gilmers' prototype minus the twin saito, didn't want to cut into the body. But it will run just fine with some nitro. Starts up with a belt drive. Going with electric is nice and clean and that offy looks fantastic. Nice to see some Gilmer projects, may he rest in peace.

I Went back to the dashboard to add detail - this is how it went.

I used a very small meter took it apart and fitted in custom aluminium bezels I made

You can also see some additional holes at the bottom - these are for the new (working) steering wheel column

Holes required for the ignition key and voltmeter - other gauges were glued in place.

The ignition key works and will turn the engine on / off. As you can also see the engine is reving at 3,000 rpm !

Forgot to add that on my dash the steering wheel hole wasnt exactly in the middle of the dash, and the knee cut outs were not equal - but they are now.

Its been a few months, but I haven't been idle. My first attempt at running with an electric motor was a disaster. I stripped the chassis back first, its already been modified when I had a Saito twin fitted.

Then I fitted electric motor

The gearing in the rear axle was too low and the motor controller overheated and burnt out. So back to the drawing board. I completely rethought the problem and came up with a solution that involved a few of these:

Sorry I cant remember. I bought it several years ago when I first bought the Gilmer. Think it was from China.

Electric motor build up.
I used nylon gears, but they were too narrow so I joined 2 together, and there are two different sizes needed.

They are fitted on shafts and held in place with brass disks

I made some bearing holders - two were required for each end of the shaft.

Assembly of the gears and motor in the frame. This took a lot work to position the gears correctly - not too loose and not too tight so they would bind.

20200502_080236.jpg
And finally the motor

This was a perfect fit, and I packed the end with 1mm thick Ali sheet held in place with 3 grub screw - so the motor is held firmly in place.
You can see also the speed controller which was placed above the motor as a temp measure to test the running.
