Hi Jon
Just thought I'd let you know, I tried the 25mm water pipe to replace the nylon bushes on my old Manor/Fleming Micron digger you suggested, It worked so well, I replaced all of them.
I've also renewed the 2 main greasable pins as they were worn. Now there is virtually no play on the main joints, the rams or the slewing ram, it's like a new digger.
I also now have enough material to replace the bushes quite frequently for the rest of its life (25m) it'll probably see me out.
So if there is anyone else out there with one of these old diggers with worn bushes, a roll of 25mm bore, 32mm o/d water pipe will do the job, £23 for a 25m roll.
Thanks again for your help Jon.
