Old pair of forks, fixed to a bench, will work quite well.
I gave my truing stand to plagiarist, how cool/bit of a cnut am I?
It's still serving well, that stand has built many wheels. I just put the parts next to it, offer up a sacrifical beer to the veloGod and go to sleep. By the next morning the wheel is not only built but fitted with rimtape tube and tyre and on the bike it was intended for.
Now all I need to do is work out how to inform the cycle deity of the correct PSI as he always under inflates, the useless cunt.
