Is it me, or is the thickness of the material, to be used for the rear upright, nowhere specified in the book?
Does anyone have a clue?!? 3mm? 6 mm?

Thanks in advance.....

Imademine out of 10swg (3mm)

You're quite correct, there's no specification, but if there was, I'd put money on it being 5mm plate, tiger seems to have something of a love affair with using dirty great clods of steel wherever possible.

I'm making mine out of 3mm after recomendations from rorty, and realising just how big, heavy and damn horrible to work with thick steel is.

Thanks guys,

I'll also ask the MK Indy-gang to measure up theirs, just to be sure.

I have looked at the book and is it really 4 mm thick walls on the main frame.
I live in Sweden and the standard seems to 2mm at 25-25 pipes.

I don't know what Tiger have used but if it is anything like there wishbones it will be thecheapest of gheap,
16swg is plenty for the chassis construction.
