What’s that saying - “little boys never really grow up - just their toys get bigger”?

Ah, Tumble buggy from Goughs youth, is it surprising the Marco's is red and the SS1 is blue??

Forgot to say at weekend, the 551 number really works, that's a nice touch 8)

Ah, my tumble buggy was yellow. Brilliant until the aerial broke off & it stopped rolling back on to its wheels.

Good luck with your repairs, I'm looking forward to seeing this car in the flesh.

Do you think the rear chassis delete will catch on? :D

Speaking of childhood toys... Snap! I win!

And then you can just stack it on it's tail to save space.

The race at Donnington was live streamed and is availble to view.

It doesn't show my "off" and I only have fleeting appearances, commencerate with my lowly grid position (33rd from 40):

I don't suppose you know how much lopping the rear chassis legs off saves in weight?

Visit the "facilities" before a run - probably saves more weight :mrgreen:

In your case, don't forget you're Roadgoing - lopping a foot off the chassis might cause issues with DVLA plus you'll still need something to hang the exhaust off :wink:

There's not much to the chassis section, so it won't weigh much, but I'll weigh it at some point. Plus I am putting something else back in, the body panels won't hold them selves up.

I was fortunate that Iain Daniels offered to help me this weekend, with the replacement frame for the bent bit of rear chassis. The remaining piece of bent chassis on the LH side was cut away & a repair section made. We then made inner sections to fit to the remainder of chassis leg behind the rear cross member, to create a box section. This was then capped with a flange, that the new frame can be bolted too. Iain welded all this up.

We mounted the panels to the armature and with the car on Iain’s flat set-up floor, aligned the rear of the body so it was level, measuring & eyeing through.

The idea is that the chassis is stiff & the tubular frame is not as stiff, so that in an impact, the frame will give way before the chassis is damaged. However, the new frame shouldn’t be as bendy as the original rear legs as the legs come straight back & are cross braced, so the tow eyes can be attached to this & I’ll lose the old seat belts I was using as the load transfer for the tow eyes.

Iain cracked on & made the tubular frame and got it half welded up (we ran out of time); whilst I set about straightening the LH semi-trailing arm, which took a bit of effort. If the arms hadn’t been converted for rear disc brakes & rose-joints in place of the bushes, I would have just swapped it out for another arm. However, the wheel is now pointing in the right direction again.

A huge thanks to Iain for his time, assistance & welding. I just need to get the rest sorted for racing on Sunday...

I’ve had to cut the swirl pot mounting bracket down a bit, so that it fits to the new chassis arrangement & completed the welding on the tubular frame this evening. I need to get some paint on the frame & armature tomorrow so I can then start the re-assembly. At least it looks the right shape when it's covered up!
