Abba stand dimensions

Hey everybody
Ok so I want a abba stand, however with me being a cheap skate don't want to pay £100 odd for one. So I want to save my self about £100 and make one at work. Only problem is I dnt know how big they are. The dimensions I need are
the base to the centre of boss with the locating/pivot pin(the bit that goes into the swing arm pivot)
The length of the horizontal bit of boxing
The length of the of bar on the bit that's welded onto the boxing where the adaptor is put, on the fixed side.
The size of the plate that the stand rests on when in use and the angle it is set in relation to the boxing
Also this is just a query, the addaptors are they a nice slide fit into the swing arm? Also do one of the addaptors have a chamfer on?
Any help would be brilliant, saves a lot of guess work
Cheers
Matt
