Sorry for jumping in Morrag, but I could see you weren't on line at the time Smiley

Ah, not my problem then.  I get wear in the splines in the bike part of the prop shaft.

Good point about the brinnelling, not something I'd considered to be honest. At 40mm vertical and horizontal offset it should be OK?
As to axle widths, yes I could run it narrower, and it would save me lengthening one side, however I think I prefer to keep the width.
Thanks again for comments,

11 degrees was the ultimate offset to keep those rollers rolling. But that was years ago I learnt that so could be 11% ?

A quick update, made up one side of the axle, new tube, machined to fit, with the original end bearing housing welded on. Some pictures:-
oh poo, too big again.

If you are running Mirosoft's Office on your PC/Laptop, then open your pics with Office Picture Manager, and modifying file sizes becomes a breeze! really, just follow the task bar "destructions" Wink..Morrag

Thanks Morrag, don't have office on this machine, a lightening strike took out our main pc around christmas  - (still with insurers), and my samsung tablet has died.
 Tonight I made up the long tube, banged it in to the short casing with a small sledgehammer, so nice'n tight. Need to make up a shaft which I'll rob the 750 axle for (only need the splined end). Before "pressing" in the tube I checked the diff preload, or rather if I had any!
I measured 26 thou on one side, which gives 13thou preload. It feels like it too, with the diff noticably draggy when tightened down. So my question is simple, does anyone know what the preload should be? Also, are there shims available for fitting behind the roller bearings?
thanks,
Huw

Trike still in bits, Tubes made and fitted to the axle, shortened one shaft no probs, but when I pulled the shaft out of the early axle to make the "long" shaft found it was a spindly thin thing! If anyone has a later thicker shaft they want to swap for a narrow one let me know..
Made it up anyway, we'll see if it holds.
 Have started making new seat rails to suit the King/Queen seat, pig of a job, working upside down backwards. Hopefully will have the steel to finish the seat rails/frame to the new axle by the weekend. And I promise by then I'l have some pics...
One Reliant question, does anyone have the procedure (possibly using some spacer tools) to shim a reliant diff? The pinion teeth on mine are hopelessly worn out, so it's time for a replacement crown wheel and pinion. Life's never simple eh?
All the best,
Huw

Once I have the seat rails and frame back to the axle made up I'll post some more pics, right now I'm fighting with the pipe bender, ideally I could do with a big propane blowlamp...

Thanks Fifer, a mine of information as usual. I'll have a look. Also, thanks, the link somehow took me to photobucket, I've been putting it off for ages, hope you like the pics.
