Subject: Keeping the Telrad On

Recently the adhesive strips that came with my Telrad deteriorated to the
point that they would no longer keep it secured to my scope. I tried using
some double-sided mounting tape, but this appears to be only strong enough
to hold the Telrad for a couple of days. I'm going to use some heavy duty
duct tape next, but I'm wondering if anyone has any suggestions for a
nontape solution?

Why not use silicon adhesive? holds tough but removeable and won't mar
the surface.

An alternative to using DS tape are zip ties. Use the long white or black
ones found at Home Depot or Lowe's. They can be fastened together to fit
any diameter OTA. Easily removed or replaced and will not damage the OTA
paint. The ends can be be trimmed for a neat appearance.

I also used that double sided tape, but I went one steap more, I used a few
drops of super glue on the tape to hold it to the scope and then I used a
bead of Ambroid modeling glue to hold the telrad. It's been on for 5 years
now.

You need to use better double-sided tape, like 3M VHB. Supposedly
RadioShack 64-2361 is the same stuff. It will not come off without damaging
the surface it is applied to.

Thanks, Dennis and Chris. I noticed while putting on the duct tape the two
holes. I'm reluctant to drill for lots of reasons, not the least of which
is my general mechanical inepitude. I like the velcro and better tape from
Radio Shack. I'll check our local shack in the near future and see if
they have it. Might even combine it with Chris' suggestion on the velcro.

If you don't try, you will never gain the experience and expertise in doing
something!
If you've got a drill motor, go down to the hardware store and get some
small machine screws and nuts that will fit in a 1/8" hole and just attach
the base with the poor tape you do have and then, when the finder is aligned
right, drill the two holes and put the screws in.
You CAN do it!

I sure can. I can also ruin my optical tube. Trust me on this.

The other place that will do better tape, in small quantities, is a car
accessory supplier (main dealers included). On many modern cars, the
interior mirror, trim, number plate etc., are attached using such tape!.
Key with all such tapes is surface preparation. Clean at least twice with
alcohol, and allow to dry completely. Cleaned properly, some of the better
stuff, is amazing.
Best Wishes

Two things I've done with different scopes:
I have one Telrad permanently mounted, using the screw holes in its
base. This is, of course, how you would normally attach conventional
finders, and it works great if you don't anticipate needing to move the
Telrad.
On another scope, I put rubber pads under the Telrad base to keep it
from slipping, and attached the base with a couple of Velcro straps (the
kind with hooks on one side and loops on the other). There's plenty of
space between the base and the Telrad for the straps. This setup is
remarkably solid, but very easy to remove or relocate.
