Chassis identification - STM Locost?
Hi
Are there any identification features of a Stuart Taylor Motorsport (STM) built Locost chassis please? I purchased an old unregistered rolling chassis
that looks like it might be a STM Locost. For example it has a round tube hoop support (across the car) for the upper steering column just under the
scuttle and front wishbones from curved round tube (and an even less conclusive none cone with STM number on it and grp scuttle panel). Anything else
to look for?
Just curious really, whether my chassis was jig built in a limited production run, rather than a DIY build. If it is STM I suppose it would make sense
to register it as such; might help a sale in the future as a bit more of a known, not necessarily superior, quality?
I do realise an STM Locost chassis would have been built down to a price and the limits of the Locost design, rather than one of Matt’s Procomp Locost
chassis or a lovely bronze welded older Caterham or Mallock chassis from Arch Motors. I seem to remember comments on here years ago about the quality
of some STM fabrication, e.g. pedal boxes. I do recognise some DIY builders have produced excellent Locost chassis which are dimensionally correct,
not twisted and properly MIG welded.
Or could it be an MK Engineering chassis from the Martin Keenan days? Were the curved tube wishbones MK?
Cheers
Mike

I seem to remember that the very back of the car at floor height was all square - hard to put a replacement back panel on!
This might help...

Many thanks, just the info I needed, will check in the garage but looks like my chassis from memory. Oddly my chassis might actually be the one
pictured, wonder if the seller in 2012 sold it to the late Mick Heyes?
How you doing? How is the Autotune Gemini build/operation?
Cheers
Mike

Cheers

If I can wangle some garage time I can take some photos of mine once I've seen your pics. See if looks similar.

What do you think - STM?
Thanks

Thanks all, that is very helpful. What were the giveaway signs?
Any pictures of the back panel of an STM chassis that has been ali panelled? I am wondering how I deal with the right angles at the bottom corners
compared with the rounded top?
Cheers
Mike

I'll try and do some photos next time I'm in the garage. The bottom of the rear panel just had a 90 degree bend on it with slots then
riveted. The top I had to dress the Ali round the circular tube with a leather hammer.

Hi all
What a bunch of knowledgeable and helpful folk. Thanks so much.
I have updated the pics and info at: http://austinhealeyspritemk2.blogspot.com/2020/07/locost-new-project.html
I managed to track down an earlier owner who supplied more info and pics of my car.
Cheers
