Fabrication deDion
What is involved in making a deDion axle? Is it really easy as it looks (cutting the hubs of the sierra trailing arms and welding them back to the
deDion axle) or is there more involved?

Phil Rowe of Oz has a very good page about his de Dion construction; not a Sierra, but hope it helps:

IMO, jigging would be wise even with a GTS de Dion kit. Not sure if GTS recommends it or not.

The first design looked very strong, shame the handbrake linkage fouled.
The second design with the single plate joining the hub to the de-dion tube I don't like at all. It's just begging to get bent on the
first decent pot hole IMO, especialy when you work out how small the cross-section is at the hub fixing bolts nearest to the de-dion.

I believe thats how most people fix the axles to the dedion......!

Caterham's design is similar to the second one

How big are the potholes round Plymouth  . That looks like 1/2" boiler plate and I've tried to bend that without success unless you can
get it glowing red first. I would be confident that it wasn't going anywhere.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I have a couple of photos of my De Dion design which I fabricated and looks very similar to the Catheram. Just have a look at my photo archive
Should you need any more details just send me a small mail
Regards
Philip

Some pretty huge ones around here 
Look at the total cross section where the bolts attach the hub to the bracket. There's not a whole lot of metal there. Now think of a big
wheel and tyre bolted on which can exert some serious leverage. I'm not saying this design couldn't work, but using huge slabs of metal
is not a very elegant way of putting strengths into something.
I much prefer the way that Darren has built his axles, a much more rigid design and probably a fair bit lighter.
