The bumper that was on the car was in a rough state. The formed edge was cracked, the bottom seemed to have been used to stop a belt sander and the whole thing was curved.







The bumper is made from nylon and glueing nylon is not an easy task. Generally, it will only bond with heat. I tried with hot glue but that didn't work. Then I found this loctite Kit. It comes with an activator which seems to be Loctite 770.



This combination of activator and glue works well and according to the package also glues polyethylène and polypropylène.

To straighten the bumper, I used the same glue to stick on a square carbon tube next to the edge.



The body post was cracked where the screw goes but with a tie wrap, that was a quick fix.

The front wheels on this car had been replaced. As far as I know, all Jerobees that were made before the Lightning 2000 had the classis rimmed wheels and rubber tyres. This car had the Lightning 2000 wheels without rims but with the rubber Jerobee tyres glued on instead of foam tyres.



This is a period magazine picture of the chassis with electric motor and the classic wheels (in mirror image).



And this is an advert of the Lightning 2000 with the new wheels, oilite bearings and foam tyres



The rubber wheels didn't stick well and were quickly removed without effort. I went shopping on the web to find foam tyres that suited the 35mm wheels. I found and bought these Swiss made tyres



Once received, I had to adapt the tyre width. I stuck some masking tape onto the foam and marked the right witdh. I could easily cut the tyre to size with a cutter knife.





The wheels are secured on the stub axles with E clips. 1 was missing and was replaced by a steel wire. I once bought some new ones; they're the same as the clips fitted to the clutch shaft.



When looking for parts of these cars, it's not good to stick your brains to the name "Jerobee". As they were the pioneers of the 1/12 scale, many dimensions of parts were taken over by Bolink or Associated.

This completed the chassis. Still to fit is the RC gear and the linkages.

Some before/after pictures

Thanks for the comments.

The Porsche 917/30 body is rather rough but as it is an original Jerobee body it deserves to be saved. The spoiler is completely detached on the sides and the hole for the rear body is inexistant. I got some plastic sheet from blister packages and glued this on the back of the spoiler near the sides with époxy. the body mounting hole was recreated by pushing a hot brass tube trough the plastic.





I then sprayed red polyurethane paint on the Inside. To straighten and reinforce the rear spoiler, I glued a piece of coroplast on the Inside. To fix the body on the chassis, I used large Lightning 2000 body hair pins.

I met Don Mckay at Bladder Grabber 36 or 37 went to his house and had dinner then bought a bunch of his Fast Combat equipment, engines and a few planes...$800 bucks worth cash money

Had every intention to play in the big boy big block fast combat game

Over the course of the evening Don related to me his involvement in the car hobby industry

I still have his e-mail if some one need to ask a specific car question from I think a guy who probably knows

Don does not do forums or very much at all with the interweb

Glad you like it. The body shell is not perfect. The big cracks were repaired with blobs of hot glue to stitch both edges together quickly while holding them with one hand. The plastic and coroplast was glued with 5min époxy.

I remember that Duke Johnson from Washington knows Don McKay as well. It's been a few years now that I didn't read a post from Duke. I hope he's well.

To store my 2 Jerobees, I avoid to put them away sitting on their wheels. Otherwise, this will create flat spots on the foam tyres after a certain period of time. I use toner cartridge cartons for my printer that I adapt. I cut out the cardboard where the wheels go. The cars sit then on the chassis with the wheels free.
