I got the frame up in the vice with soft jaws, using the rear forks to true the new wheel. this stage I was just going round all the nipples putting half turns on to tension them up slowly
heres the asda value method I used to true the wheel, worked out that including the rim thickness it was bang on 20mm either side to the frame, so I clamped a straight edge across the gap and watch the wheel wander off of the 10mm mark, then tweak the nipples (fnar fnar) to pull the rim whichever way required
with that done I fitted the chain guard and sprocket back on. I noticed the sprocket is dome shaped, can anyone confirm the concave side points outward as in my picture? can anyone also confirm whether the thicker shim goes behind the sprocket or thinner ? anyway I tried the sprocket with the concave side pointing to the hub and the chain would be running on the guard.
then checked the bearings on the untouched new front wheel, all nice and greased so set the bearings back up. then was able to dress the wheels up
last picture here ive carefully reassembled the crank set (or bottom bracket I think you guys call it) and the head set, also fitted the crank arms and new cotter pins
