Magnesium chassis - not Cox!

Magnesium slot car chassis are usually synonymous with Cox, but other makers made them too, not to mention scratchbuilders. Still, I think Cox was the only company to make a car with a mag chassis. I recently picked up a MIP chassis by an unknown company, E&J Engineering of San Diego, and in the last year or two I've found a few more, in both scales, so finally got inspired to start a thread. I'm not including dragsters here, since mag frames were more standard in that area.

Here's the E&J chassis, a rather odd beast, which I also took out of its packet to give you a better look; I thought I already had one of these under a car, but it wasn't quite that. I've also added two contemporary mag chassis by well known companies, MDC and Kemtron. Somewhere I have one by a company called Ross, but couldn't put my hands on it!











Here's the chassis I got it confused with, along with another one that seems to come from the same manufacturer! Anybody have any ideas about who could have made these. They seem too well made, and the 2 too similar to be a one-off. Note that the shorter frame has its body attached by small screws into tapped holes in the frame, like a dragster, even tho it's a vac-form Lotus 30.









to be continued...

Here are a couple mag chassis in 1/32, rarer in the small scale. One is a pure mag chassis (but with aluminum spacers) under a Cox Ford GT body, while the other is a sort of "over-chassis" for a DC916B, also using aluminum spacers, plus a brass drop arm.







Here are three scratch 1/24 cars, two of which I've already shown, since they're both magwinders. The Sportsman as a home-made mag frame combined with a Dyn-O-Charger; the Cheetah is one of the few magwinders I've found made for sports/GT cars, and I just freshened it up a bit and put on a new Cheetah body. The rear part of the chassis in the Vanwall is as found, probably for a dragster project originally, but not sure. I put on a front extension and fitted it into a Merit Vanwall. The last photo is a small sampling of the mag chassis projects I've found.













Let's see your Mag Cars!

Don, those were home built by a guy who did know his way around his machine shop. We have a Lola GT built by the same guy, using a similar chassis and details, also painted in red like that Lotus. Very nice builds, but not commercially produced.

Lots of nice chassis there Don . Sure , magnesium is lighter and stronger than aluminium ...but the greatest flaw is the corrosion factor . I have lots of Cox magnesium wheels , and trying to get them back to a shiny finish, is just about impossible. If you do get a reasonable shine happening, after a few months, it's time to try all over again.
Is there a suitable coating that can be applied, to keep the shine going ? Maybe some out there like the black tarnished look of corroded Magnesium ? I certainly don't !

yeah, one more piece of equipment I need: a bead blaster! Over the years, for really cruddy stuff I still drop them in lemon juice or vinegar for a minute or so, then a toothbrush to clean it up. From there, for wheels I get them mounted up in my electric drill, and while spinning apply steel wool to as much of their surface as possible. It won't get every nook/cranny, but they sure do look nice after a bit. Do the inner rim as well. Blow them clean, then a spray coat with either dull or gloss lacquer does the job. No, it won't last forever, but it will for as long as I will be looking at them!

stuck,
You may be aware that small bead blasting tools similar to airbrushes are available at reasonable prices. I considered getting one when renovating a Cox BRM a few years ago but instead did something similar to you!!
Would be interesting to know if any SFI members have tried these.
