Replacing Lens in Vintage Frogskins?

[tigbball5]

So I just got a pair of vintage frogskins and the frame is in amazing condition. However, I'm trying to replace the lenses in them and having a lot of trouble. I have heated up the frame, no luck (and the heat destroyed one lens). Tried it without heat, no luck. Someone must have done this and been successful. What is the trick to it? Any thoughts on breaking the lens?

Why are you heating them?

I'm not a Frog guy, but they should just pop out with some muscle. Or are you trying to avoid snapping a brittle frame?

All my Frogs are new but you can just pop the lenses out.

I done it...

It just takes a big of muscle ... The frame should hold up...

Alright thanks guys. I pushed from the upper inside of each lens extremely hard and they came out. I am a little disappointed that the newer frog lens doesn't fit as tightly as I thought it would.

Vintage Frogskins lenses are a whole lot harder to get in and out than on the 3rd gen Frogs.
And no, they are NOT compatible or interchangeable.
Some unscrupulous sellers mislead when desperate to unload their goods.

3rd generation lenses ---> vintage
Vintage lenses --/--> 3rd generation

That doesn't even make sense.
Maybe what you mean is, the 3rd gen lenses can fit into 1st gen frames, but the fit obviously is loose.
Like wearing size 40 on a size 36 waistline.

Nope, not on my G1 frog...

Toight like a tiger!

Not sure how you define "Tiger-Toightness", but if that's the case, what would original gen 1 lenses in gen 1 frames be, "Tiger-Mom-Toight" ?
