Hi Tim,

I build a jig with scrap lumber to hold the mirror box
and UTA and prop it up against a sawhorse or wall. 
The UTA is on a sliding right-angle fixture.  I move
it back and forth until all my eyepieces and
binoviewer focus within the travel of the focuser, and
clamp the UTA in place.  Then I design the truss tubes
and clamps to match the distance between their
attachments on the mirror box and UTA.
