I expect that the OP has run up against Jon Goodman's relatively recent change of policy - he no longer sells the foam by the sheet. As I understand it, he changed his approach due to the people on eBay who were pirating his custom instructions.
Thanks guys. Thanks very much for your support over the years. The piracy, copyright infringement and outright dishonesty displayed by the various parasites was a problem. And these people are as hard to get rid of as cockroaches. You'll notice I never removed the free instructions I had posted on the KYPhoto site, however. They're still there for people to freely stea...umm, use.
Another foam problem not many understand was caused by the tsunami. We all saw the horrible damage, but changes followed. Reconstruction took time and this gave some a chance to repurpose themselves. This means today they could be making anything...vinyl purses, rubber shoes, wetsuits, drink can koozies, weird hats to wear at sports games, other things but not sheets of foam. So today prices in the custom foam market have skyrocketed as suppliers are fewer and large buyers (think Toyota, Honda, Boeing, GM, Ford) get favor. If you want proof of this, go out and buy a low to mid-priced sofa. Take it home and open the zipper on one of the cushions. You will probably see what looks like bits and pieces and odd-shaped hunks of assorted foams packed into what resembles a cheesecloth sack. In a year you'll be trying to figure out how to re-distribute those bits and hunks so your cushion looks good again or you'll be out buying another and more costly sofa. Go to Jo-Ann's and price slabs of foam to use in upholstery work. Here...I'll save you the trip.
http://tinyurl.com/y9jhzrzj This previously was about $6. On the tree of foam, this is pretty low grade. I used to sell kits for $6 that would allow the user to re-seal 6 35mm cameras. Today that kit would have to be priced at $50 or more. I am certain Curt (MicroTools) can no longer get open-celled foam of the type he wants or like me he's found it and it is too expensive. The days of being able to sell a high-grade custom camera foam in sheets are over. Please don't get me wrong. You can go out and find some cheap junk foam to use. It isn't good to begin with, would never have been used by a camera repairman and is it really what you want to put into a precise instrument? To me it is like going in for a vasectomy and seeing a bleary-eyed doctor with a cigarette hanging out of his mouth wiping off a pair of rusty garden shears with an old rag and a bottle of whisky. I have been working since the beginning of the year with companies in America to create for me a foam which will mimic what I've been using, but it has been a tedious, time wasting and
very expensive process with lots of disappointments, dead ends and setbacks. The volume I'm talking about is small potatoes. Well, no. That isn't right. It doesn't even qualify as a single potato in their world. Much more like a lima bean. The foam I want can be had but once again the price is crazy (as an example one company quoted me $72 per square foot for one specialty foam...please let me repeat...$72 per square foot for 1.5mm foam without adhesive). Even though it was nice stuff, there is absolutely no way to go anywhere good with a cost basis like that. I can't do it, Curt Fargo can't do it...nobody can. But even though it has devolved from a pizza and beer fund to a pizza
or beer fund, the "light seal project" will continue. I'll keep you posted. I have already secured mirror damper foam which is very nice and am working continuously on the rest. And I still have plenty of foam to make kits until the time US alternatives come through with a solution.
Note: if you need a bit of foam to use as a mirror damper please contact me. I've probably given away as much foam as I've sold over the years and I'll do my best to help you, too. I have a little ELE foam left here in a couple of thicknesses which makes a great mirror damper, looks exactly like the original and should last for decades. In fact, I use this for the inner damper of the RB67 and have done so for years. Please don't use any of the thick heavy junk foam out there. The original poster is right. It is totally wrong for your camera and will ruin your mirror linkage.
