I cleaned up the inside wall with a small grinding wheel on the drill, so you do not need a reamer, unless a lot of metal needs to removed, and that
would cause a failure in itself, too much metal was removed

I think there may be a bit of misunderstanding here.
I'm planning on reaming the bush once it's fitted inside the wishbone tube so that the crush tube fits nicely.
I'll report back on Wednesday when the reamer turns up.
Spot on.
The idea is to ream a thou or two of "poly" from the i/d of the poly bush.
(No metal should be harmed during this operation) 
My bushes were 14mm i/d before fitting and 13.85 after. As previously stated I used a lathe.
A new 14mm drill was placed in the 3 jaw chuck. An MT drill chuck in the tailstock with a short stub of 14mm round bar in it.
The w/b was forced a little way onto this stub, then the w/b & tailstock slid up to the drill, and then turning the chuck by hand
the drill gently reamed out the bush.
Turn the w/b around and repeat for the other side, although this time it will slide easily onto the stub.
Perfect alignment and perfect for size.

Reamer turned up early
Seems to do the trick. It's an adjustable type, so I just removed a little at a time until the crush tube fitted with a little resistance.
Bolted the wishbone up to the chassis and it's much better. It almost falls under its own weight now.
Thank you to all who have posted.
I look forward to a creak free, better handling car.
Cheers
Matt
