sheet of 7mm. I think I was lucky with the 3mm it doesn't appear to
have any noticable voids. The only difference is the 7mm made of pine
and the 3mm outer veneer looks like some sort of hardwood. Anyways
they're now in the press being laminated with the good sides out.
So I've rebounded and jumped back on the horse  . After the painful
death of my first effort with the SC  , and the workshop disasters that
followed  . I'm not going to try and copy the original, I'll only make mistakes
and I have ali tube for the struts. But I'm still going with the slimeline SC
style to keep the weight down.
So I have a Q, is Shelly's exterior PVA ok to use to glue the ali tube into
the plywood rings? as they intend to be permanent. Or is there a better
alternative addhesive.

You could try Mister Ply and Wood. The hoop pine is reasonably priced and good to work with.
Rob did you do some sort of drawing to calculate the angle of the truss blocks? It will be a shame to do the same mistake again.
I usually use an epoxy for the truss tube blocks but for the ply wood rings PVA will suffice.

in the end $400 is $400 not going towards a 16" maybe... hopefully... eventually...
Still it is tempting  too tempting  no if I was going to spend a bit
of cash at present it would definately be on a 2" OIII filter .

In the future you might want to sell the telescope and it would be nice to sell it with the option to fit a bigger size mirror. If you are going to build the cage again making it 2 inches wider should'nt be a problem.
