Truss tube design

Posted By Stephen Tatsumi
It seems that most if not all truss tubes are round. I have access to aluminum angle, 1/8" with 1.5" legs. Would this make acceptable truss tubes or would they flex too much. This would be for a 7" F6.7 dob.


Thanks

Bogen Tripod Repair

Posted By Stephen Tatsumi
I have a Bogen 3036 tripod and need to replace the bolt on the tripod that a tripod head would screw onto. Can anyone shed some light on how I would go about removing this bolt ?

Thanks

How to verify quality of ED lens

Posted By Stephen Tatsumi
If a lens is advertised as being an ED doublet multicoated on all four surfaces how would I be able to confirm that it is? Thanks.

Some new pictures on-line

Mike,

Great looking scope. I am also in the process of making a 7" dob. I would be interested to know the particulars on the focuser, spider and primary and secondary mirror that was used. Also, what type of truss tubes did you use?

Thanks,

Steve Tatsumi
