Hi Wasp,
Yes, the wheel jig I purchased off E74 is perfect for what I do.
The ones I have seen at pro wheel builders premises are made by themselves kind of like some of the home made ones that were discussed when I was looking for mine. They don't seem to buy smick ones like the ones you import and I have now, except Don Newell he has the best I have ever seen.
Do you carry spare parts for my unit, if I need some.
The wheel building table I referred to before is for setting the off sets and making sure the rim is centred on the hub. In the centre is a lathe chuck that holds the drum true to the rim. There are level adjusters that set the off set on one side of the rim. When all these 3D measurements are right the spokes are laced and the nipples are turned until finger tight. From there the wheel is taken to a wheel jig or wheel truing stand where the fine tuning is done.
