Great job onthe spider, feels great to save the bucks does'nt it.
I just finished my secondary using Kriege's book as a reference and the couple of mills of countersink seem to make the secondary more solid. I toyed with the idea of not countersinking but now I'm glad I did. Just take it slow with the drilling, its really easy to go too deep. Countersink first then drill out the wood for the bolt. By the way I ordered tube inserts from Obsession telescopes (

Adios
