OK I got the quote back from an Australian Laser Cutting manufacturer (Lightning laser cutting in Victoria), for a 1 off made to test it will cost me $82.50 a pop. Obviously a single one is dear but multiples are a lot cheaper. This is based on a dia 200mm and a central bar of 20mm with 20mm added to the outside, and 250mmm for the larger one. Looked at two different materials – black acrylic and stainless steel 304 grade. I haven’t looked at a way to fit these to the scopes, although a 90degree clip screwed to the template with a plastic screw to attach to the scope did come to mind, or even a Velcro attachment? As didn’t get a quote for the 10mm spacings, as I thought at this stage that was pointless, but I would say it falls between the two. Smaller diameter masks were not looked at yet, but where they are less in material the same setup costs would be involved, so I don’t envisage them to be much cheaper. Postage is not included in these prices, obviously there are economies of scale – so quantities of more than 5 will bring the prices down – but then it all comes back to how much do you value a gadget? For me I think this will be priceless, especially considering all the crap images I have taken off late that are out of focus.
