Hi All

Regarding thin metal components for spider vanes....

Long ago when I was a kid, my father made a spider for my 6"
Newtonian. He must have used hack-saw blades.

The teeth were ground off and if I remember correctly, he also ground down
the sides to make them thinner.

These were then brazed to a thin walled brass tube which was the main body
of the spider. Although it appeared flimsy, the finished item was amazingly
strong.

For what it's worth...

Cheers
Frank Q
