Thanks mate, for your comments on my scope... just waiting for clear
weather and a moonless night to give it a whirl. I thought the same as you
regarding carpentry skills. Hadn't done any since leaving woodwork classes
in high school nearly 30 years ago. I built my first one at the end of last
year a lil 8" for my son. There is an excellent book you can buy called
"The Dodsonian Telescope: A Practial Manual for Building Large Aperture
Telescopes" by David Kriege and Richard Berry. It's an excellent book
for the layman and easy to understand and it goes right through everything
including the the mathmatics.
I think your idea is a good alternative. But the way your attaching the
tension lines will create stress on the SC as soon as you tighten them up.
I would attach directly to the strut as this is what you want to make rigid.
The problem here is if you go the full length of the strut you are more than
like going to have the mid section of the tension line traveling through the
light path. To get around this you could shorten them and attach them
midway up the strut and still retain a fair amount of rigidity.
I would use swaged FSWR with a hook on one end and a turnbuckle on the
other. A turnbuckle is two eyebolts/hooks joined by a turnbuckle. You
can use the turnbuckle to tension up the guys. Similar to the picture below.
regards,CS
