TIN CHASSIS

Jason. Who is herr Kruth ?

Ruid's brother (sorry off topic)

[Eddy Wright]

Oh ! I see.

[mrequipe]

Okay, I originally said this was an enquiry, It is from an overseas crew. They have not asked would it be CMRC eligible, I just wondered !! as it was done in the period. I am quite happy making tubular chassis and I think this is how they all should be
I also do not want any rule changes, in fact as Sidecar bloke will confirm I want the rules tightened and in black and white to stop costs escalating.

A lot of people turn things around on here, and what was supposed to be an interesting subect turns into a s-it fight.
I know sometimes I dont post things of interest to the majority on here because people get the wrong end of the stick

Do you think this enough on this subject Bob / Steve

To quote Mrs Merton, "Lets have a heated debate"

[Ian E]

Now can we get back to the original point? Mike's proposal would require a rule change, so my questions are:

Does the proposal offer any significant performance advantage?

Would any rule changes be easy to enforce?

Does anybody object?

In answer to the above:

Does the proposal offer any significant performance advantage?
I can see how the Box section will be stronger in some section than other and can be tuned to be as flexible was wanted by changing section and thickness, how much of an advantage overall this is debateable on how many frames are built to improve the handling.

Would any rule changes be easy to enforce?
If the section and wall thickness used is the same as that ran in the original Era it should be easily enforceable.

Does anybody object?
The objection will only come from overall performance, and the real performance is in the design of the frame over the section used in the frame, the flexibility of the frame is fine tuned by the section, but the over-arching handling comes from wheel layout suspension and size of wheels, engine performance and brakes.

I personnaly can't see why things should not be changed if it keeps within period and concept of the class.

Hi Ian,

Thanks for the reply

Mike,

Fair enough. You did ask in an earlier post if it would be CRMC eligible.

Jason. Who is herr Kruth ?

Clearly it wasn't me saying that and John Carters all ready had that joke when Ian done the post, But i'll let you off bearing in mind your age

I have a Tin Windle or Winstanley, not sure which. Originally built for TZ750. Still in good nick, but some twat fitted a GPZ900. I believed it to be of the era "late 70's,early80's". Would be super to marry it up to aTZ???

My old man bought a 'tin windle' had Box Section Ally for the main frame, tubed for sidecar section (with a TZ 750 in it). What a bike for me to learn racing on

I think Terry built a few of them for 79 as i sure that when the Great Jock had one?

Mike - I think possibly that this has been done to death by now including a number of not really relevany posts due to a misunderstanding of the original design by Rudi.

The only problem that I foresee should such a chassis ever be approved by CRMC is that some folk may want to use an engine that was never fitted to this chassis which potentially could create a huge advantage over the original. To see my point just look at VMCC and the Mini engined Berkeleys etc ....

[petercaughlin]

Quite right Bob,if it gets made make sure it only has a 450 Honda lump in it like the original.

This is the only pic I can find of the Tin Chassis outfit:

Lest we forget the Dinosaur was the above, it suited the need at the time (1988), if we hadnt of put the GPZ in it would have been scrapped back then as it was a state.

The next short Bike rescued had the Krauser put in it... Bit better than a TZ

Why not put the a TZ back in it, it wouldnt take much just engine mounts new top tubes and a few fixings, most people on here could do it..or know someone who could
