Tube holding question
Posted 13 February 2013 - 06:14 AM
I would (now) like to use it with my equally cheap Galileoscope.
My thoughts run to making simple wooden blocks with semi-circular cuts, screwing them to the mount,
then sitting the scope in the cuts.
Before I wander to my workshop and start reinventing the wheel, are there any standard
ways of fixing mainly-cyclindrical scopes to mainly-flat mounts?
Pointers, hints and links all welcome.

The hose clamps work and can be covered with tubing as suggested or with self adhesive felt strips cut from sheet.

I started with two pieces of oak 3.5" x 3.5" x 1". I basically used the oak as it were aluminum, the clamp bolts and the attachment screw were 1/4-20 and I just tapped the threads into the oak.
The first step was to drill the 2 inch hole in the center of the 3.5 x 3.5 inch piece. I used Harbor Freight hole saw and a $50 drill press.
Once that was done, I drilled two holes probably 3/16" holes 1/2" in from each edge. These needed to be 90 degrees to the direction of the grain and and at least 1/2 way through.
The next step was to split the ring, I think I actually made two cuts on each side so there was a clearance in the middle. On one piece I drilled a clearance hole for the 1/4" bolt, the other side I drilled through with the tap drill and then tapped the 1/4-20 threads into the oak.
The piece with the threads, I then drilled the tap hole for the 1/4-20 mounting bolt in the center of the ring and from the hole side, counter sunk it and tapped the 1/4-20 threads. The mounting bolt is 1/4-20 flat head. Once the bolt was in place and I was sure that the head was recessed enough, I cut strips of felt with adhesive on one side and fit them to the rings and I was done.
They work great and they look good too, he said modestly.
