OK no way was I going to attach beams to my cieling joists as van's recommends due to space so after perusing lots of builders ideas on Doug Reeve's site I choose to modify a great jig by "Smitty".
I constructed the jig out of 2x4's, Steel angle, Steel bands and my main modification from Smitty's plans was using turnbuckles to make easy adjustment of level of the wing spar.
I used free castering steel wheels for mobility.
The jig works awesome.
The steel castering wheels are awesome for movement and the length of 133 inches between uprights work
