Protector scopes

[Mrs Vampire]

Steve asked me if

"using the "acrylafix " to bond mirrors onto cast resin prisms would produce the same results as bonding mirrors to the acrylic sheet extrusion I had made?"

The answer is definitely yes!!

I bonded two acrylic mirrors to the best of the cast resin prisms I had made. It instantly improved the optics to usable clarity. The only reason they were not perfectly clear was that I had abandoned the cast prisms before I had ground the surfaces to dead flat.

Had I flattened them I am sure I would have produced the same results I have achieved with the extrusion I purchased.

I am unsure how effective this would be if I used glass mirrors but have a very strong feeling that if the "acrylifix" would bond to glass the results would be the same.

Brian also recommended Canada Balsum . I have a similar feeling about that as a bonding medium . That is if it will bond perfectly to both the mirror and the prism "whatever they are made from, then a perfectly optically clear scope will result. My only reason for not using Canada Balsum was that It would take a while to get it to me from an e-bay supplier.

I think if anyone was undertaking scope building then an experimental cast up and bonding would qualify the mixture of products selected.

What I am able to say is that using acrylic sheet , acrylic mirrors and acrylifix produces very clear scopes and that if clear casting resins are used the same results are obtainable so long as all surfaces are sanded/ground dead flat.
