Hi, folks. I have a Technal contact printer, one of the steel ones with the hinged glass, which I bought in the early '70s. It's time once again to replace the open-cell foam pad that covers the steel base to press the paper against the negs when the printer is closed. The last time was about 14 years ago, and I recall having found a self-adhesive one. It's about 3/16" thick (or was...). I'd appreciate a recommendation for a supplier.

Thanks.

No order too small.

Hobby stores carry sheets of thin stiff foam in a couple of different sizes and a multitude of colors.

Hi, and thanks to both. The hobby store foam sheets I've seen are only about 1/16" thick; you may have seen something else.

I replaced mine using a foam air filter from and some contact cement. It was open cell foam of the appropriate thickness that I bought for about $3 from Amazon. Sorry, I can’t remember the exact details because that was a few years ago. But I do remember it being difficult to find the right sized foam until I started looking for foam air filters.

Try Walmart, Hobby Lobby and Michaels-I've seen it in several sizes .

Do it right. Go to McMaster and order foam made of pure silicone. They have a huge selection plus tech info at the start of each section. Any cheapo hobby store material is going to get eaten alive by UV; and then you're going to end up with endless little bits of sponge rubber dust getting into and all over your work.

Finally, we agree on something.

Must be the heat.
