Hi guys,
Ok - In a minor disagreement with current propshaft supplier (2 weeks so far to get to this stage) and no discernable way forward - I need either:
a)The exact dimensions of the Honda S2000 gearbox flange and diff flange
or
b) know of a decent propshaft company that will be willing to put a little extra effort in
I've measured the item as best I can, but don't fancy commiting 100% on an expensive prop.
Cheers,
Murray

I just went through this, the prop shaft guy is 160 km away. I cut the old prop shaft about 3" from the flange at both ends, welded a bit of exhaust tubing into the open ends while the shaft was in situ, then shipped the lot of to the manufactured. They need the 3'' of old prop shaft to chuck up the old shaft to machine the universal off. Make sure you have sufficient yoke on the spline. Good luck
If it was me I'd make a paper or card pattern of the said flanges and then send them to the company. You could apply a die to the flange and then
'print' that image to the card simply by pressing it against the flange. The image will be very accurate if done carefully and more than
enough for a prop to be made.
To be honest the company does not sound as if it’s being particularly unreasonable
Mr Whippy,
I appreciate their sentiment - but he said - well standard stuff like Ford we can do - so why can't they on Honda?
I think the dye idea is a good one - I'll give that a go - then machine up some of my own plates using the pillar drill and jigsaw - I can
measure the circumferance easily enough its just the PCD etc that I'm struggling with etc etc.
Cheers,
M
Try Dunning and Fairbank in Leeds or IMS in Birmingham.
Id probs try giving Jon Fairbank a ring first. He is more into kit cars. His email is Jon@dandfltd.co.uk. Probs best to ring as well (cant remember
the number).
Any company will need some basic dimensions first. The s2000 flanges may not be parts they have a lot of call for but could be standard to some other
vehicle. At least he will say what he needs. Feel free to tell him Darren Wake from Wanxiang Europe gave you the number. I posted his details on here
some time ago.
Cheers Darren
Or speak to the chap on here (Chris was it?) as he must have had a prop made up for his S2000 Indy.... Might help.
Have you tried Bailey Morris in Eaton Socon near St Neots ? just down the road from you. Always found them to be very helpful
Chris,
Thanks for that - I'll give it a go
Between painting and sketching I could become Tony Hart, or maybe Rolf Harris - can ya tell what it iz yiiitttt!

When I was at Dunning and Fairbank we had a list of all the available flanges and the ability to get dimensions.
We often worked hard to match customers odd ball flanges. They should still be able to do the same.
The important part of the flange is the register. Often the prop flange has a male register. This must fit perfectly concentric into the diff flange.
Sometimes it is possible to turn down an existing flange to suit a new application.
The bolt holes are not critical. All the bolts do is clamp the flanges together. The drive is taken on the friction between the flanges and NOT the
bolts. Therefore the bolt holes do not need to be very accurate.
If no flange is available I have made adapter flanges to take a common 1300 or 1310 flange.

Dunning and fairbank did my prop. Excellent service and theyl find the flange sizes etc for you if needed..
commercial propshaft services 0191 4821690 - team valley (tyne and wear) near the metro center.. they will make stuff like that.. they are good
too..
with regards to the bolts.. the bolts dont take the drive - they give the clamping force thats needed to keep the flanges together -
when correctly toqued any bolt should stretch - its the metals *memory* or its elasticity which provides the clamping force which is why its torqued
to the exact amount - too much it goes past its point of return

You would have to pardon my ignorance about this, but how can the friction generated between the flanges provide a drive? If what you're saying is correct then all the bolts do is hold the flanges together.
I know from experience that (even from a bike engine) the bolts cannot be wrenched up tight enough to provide a decent friction drive to not put any force onto the bolts.
We had an occasion recently where one of the bolts had disappeared. The other three had not worked loose... but they had stretched. Given that a bike engine generally gives out less that 3/4 the torque of a CEC - I would stress that the bolts are absolutely critical.
What have we done wrong?

Murray, If Jon doesnt sort you out try IMS in Birmingham. They did the drivetrain for the Batman car. Another superb company that dont get much publicity on here. They did my prop as a favour and only charged about £50. The man in charge is David Biggs but his son does more work these days (Mark). Again tell him i put you in touch. I think they have something to do with the place in Gatehead that Terry recommended. IMS are a lot bigger than people realise, maybe bigger than Bailey and Morris (who are another great company to try - Kevin Heads would be a good guy to talk to there).
