    Question Zyl build-up

    Years ago we were able to build up the bridge on a zyl frame with lozenge shaped pieces of zyl, about the size of a then-normal zyl pad on a keyhole bridge. We used to call it "zyl build-up", although I don't remember whether that was its proper name. I need some of that stuff to build up the bridge on a pair of oversized sunglasses. Does anyone know where I can get it, or have any left? Hilco used to make it, but it's out of their catalog.

    Thanks, folks.
    Andrew

    You can buy sheets of zyl through B and S, they have clear sheets or a really wierd color (stay away from this one). I believe 1mm thick sheets and it's called "build up technology".

    Have you tried the Hilco press-on build up pads? You drill into the frame and snap the pad on.

    We used to dissolve old zyle frames of various colors in acetone for just this purpose. Get some baby food jars and start a complete set now. You will want to have the goop quite thick and it may take multiple coats but you could probably fabricate an entire frame with the stuff.

    They're called Add-a-Pads and I used to get them from Hilco and then from Franel. I'll look in my stuff this weekend and see if I can find what's left of my kit.

    The key note here was that they were acetate, not injection molded cr#p that most are today. Andrew, I also had those years ago, and we could make them part of the frame with acetone. Try puting acetone near any of the cheap "zlys" sold today.

    I have seen some "zyls" that appearently no adhesive know to man will attach. Haven't found anythign that will disolve them either. But I have manage to melt into bubbles (not heat fuse) some of it with a "plastic welder.

    Best bet is to fit them with a frame that actually fits!

    Of course it is. However, part of our job is to ensure a perfect fit and at times that may require frame modifications and we had better know how to do them correctly as well.

    Actually I see lots of people that don't want nose pads....

    Might be nice if optiboarders started to list any solvents and adhesives that they have found to work and not work on plastic frames.

    Ah, just shrink it and then file the keyhole yourself. Done that a few times. Get some rattail files and keyhole away!

    Wow! :D Thank you all! What a great set of responses!

    Yes, I used to build up the pads on older zyl frames using the clear zyl build-up and acetone. Put the acetone on the back of the build-up, press it onto the frame, let it dry and then file it down to smooth it, then buff it.

    I'm also glad no-one suggested a bridge shrinker; I hate those things.

    I suggested shrinking the bridge, but not the friggin' pliers. I hate those too. I just heat and push together to shrink the bridge.
