MERCEDES W125 Diecast slot car

I had a sudden urge to do another diecast slot car, so I grabbed this 1/43 Brumm Mercedes that had been lying around for a while and went at it. As with most builds, it's taking a bit longer than I expected due to various annoying little problems (e.g. motor mysteriously shorting out for no apparent reason), but it's not far off being done.






I used a KTM motor with MRRC wheels and bevel gears. Tyres are Supershells on the front and some unknown ones on the back. The motor had to have a bit of filing down done on the magnet end to fit, and the inside of the body had to be filed a bit too to allow the brushes to fit nicely, and then the whole thing was held in place by gobs of mastic putty, which goes off really hard and is easy to work with. I was going to use a pin guide but in the end decided on a conventional guide (again MRRC), held in a brass bracket connected to the front end, the metal pin on the guide passing through the bracket and has a brass nut soldered on top to keep it in place. The front wheels are independently rotating, being held in place on stub axles made of short pieces of brass tube, inserted into the holes in the front of the body.
I need to trim the rear axles still, and add and paint some of the details, exhaust, bonnet strap, etc... I may weather it a bit too.
I was going to use an Autoart driver from a 1/32 C-Type, which was the perfect size, but after trying to modify it several times his hand fell off, then his arm, so I got frustrated and cut his head off. I kept the head and now I'm having a go at doing my own body, but at the moment it looks like an obscene blob of c@#p. Hopefully I can make it look presentable.
Anyway once the body is done I'll post a couple of more photos, then I'll get back on with the Monaco.

Finally here's a great video from of Hermann Lang at the Nurburgring in his W125 in 1962, narrated by Graham Hill...
