A bit more done.
Diff in place on bottom mounts and chain with links removed and loose.
I need to fabricate the top mounts and then secure the two rear engine mounts.
You can see the cog on the left of the first picture, for the reverse starter motor. It piggy backs the drive sprocket.
chain on!

Looking good, following this with interest 
Question:
Will the diff mount remain adjustable as shown (wondering about the twisting effect going through it), or is there more work to be done on it?
Cheers

Hello,
How accurate have you got the chain alignment, I recognise that diff by the way!
I'm trying to align my diff now and having a total nightmare, I get good alignment until I try and weld it, even being ultra careful, small
welds, tacked everywhere the poxy thing is moving out of alignment and by quite a bit, I'm using a steel rule as a straight edge.
Its moved so much I'm cutting it off and trying again, I've been told that it has to be co*k on otherwise you will break chains or at best
have them wear out quickly
Depressed

Alex, I will have two slotted guides at the top/sides with a stud right through and two stud tensioners from the top rear engine mount.
These will be fixed to a removeable cross brace on the top framework.
Hope that makes sense! 
I am just about to draw the curved guides in solidworks for my friend to cnc.
Minicooper, lining up the diff was simple. I just mounted one lug and checked the rotation with the chain on. You should be able to see/hear any
mis-alignment.
Once done I fixed the other mounting lug.
If you use a straight edge you may have different cog thicknesses which will throw your alignment out as they won't be centred in relation to
each other?

Pat, I am going to fit guides at the top and use studs as adjusters/tensioners like on lsdwebs car. In the cropped photo you can see the curved
guides

Pat,
I'm not trying to weld the diff in static as in scrapyard challenge, it's the carrier which I have made, the slotted holes will provide the
tensioning for the chain as it stretches.
Whatever method you use, the end result is the diff must stay in alignment and I find it much easier to move the diff relative the engine as it's
considerably lighter, I'll have another go tomorrow if I can't get it co*k on I'll accept the closest I can get
Cheers

I'm just not sure what your getting at Pat, but if it's good enough for radical it's good enough for me, the chain is longer than what
renthal qoute as the minimun so that should be okay

are you going to duct air to it to help with cooling?
Chris
Hopefully mine being totally airconditioned (compared to yours) will help!
Mine looks like 72 links.

am I right in assuming you've split the sprocket in half so as you don't have to strip diff down to change sprocket

A mate of mine has a ZCars mini, after being flat out for 20 minutes around Castle Combe, his chain was only slightly warm, I think his chain was 64 links, renthal quote 54 as being the limit for good temperatures and working life

Cheers David, something less to worry about!
