Sierra Rear Hub Bolting Positioning and Size
welshy - 22/3/04 at 04:51 PM
Hi,
I building an IRS/Mcsorley 7+442 Chassis and i have just designed my rear hubs (see pic below). The assembly basically consists of 2 pieces of 10mm
thick plate and 3 pieces of tube (1x89mm O/D and 2 x 18mm O/D) , please see attached drawing (if it has worked).
What i am after is the position of the bolt holes and their size for the rear hub.
Can anyone please help.
I know i could just measure the back plate but ideally i would like to know the exact dimensions as i will be producing a CNC program direct from the
model.
Thanks
Ben

2 things:
1. can you make the pic a bit bigger please?
2.get on ebay as your design looks identical to westfield or tiger uprights and there's a pair of westifled uprights on ebay at the mo.

£60!!!!!!
I thought the whole idea of a locost was to build a sportscar cheaply.
Thanks for the info though, if i had the money i would have probably have bought them. Then again if i had the money i would have probably have bought
a We&$!^%£ld

They do look a little bulky(mine will weigh 1.97kg each).

10mm??? What are you building- a McSorley +4 Abrams? Or just a Challenger 2? 
I would have thought 3mm with 3mm re-inforcing ribs would be lighter and just as strong.
I'm sure your plan is cool but if you're going to go to all the effort of CNCing stuff etc. you might as well make it as light as possible!
Especially as this is unsprung weight.

They are also nearly the same as the Stuart Taylor ones.
