Hi Jimi
I've had a similar problem coupling my Graham 2.2 (it has a very similar VTA system)with an Orbe armboard ,the graham type holes, not the SME type.Unfortunately Michell send me an armboard with a wrong front mark. Armboard is fixed by three screws so I've rotate it until reach a position where the arm works well. No problems at the end but......a lot of sweat!
