Og, a CC is too thick to slide inbetween the fork leg and the seal.
True. If i'd put more thought into it ...
O.K. then
~ various grades of plastics;
2lt cola bottle
washing up liquid bottle
5lt oil container
£1 shop washing up bowl
you get the idea.
Tip;
to remove the sometimes sharp edge from cut plastic 'flame polish' it.
i.e; run a naked flame, preferably at relatively low temperature* over the cut edge.
Obviously there's a fine line between softening and rounding the edge and burning / melting the fecker.

This is enough to blunten the edges and reduce the chances of cutting into the seal you're trying to salvage.
You can also wet your fingers and run them over the edge to smooth ... if you're quick enough and dont mind burnt finger tips.
* since i dont make plastic photo frames anymore i dont have a mini blow torch. I use a cheap lighter and dont mind burning my fingers
Just thought - over the years i've made up allsorts of stuff with a hot air gun, a lighter, a fret saw and scrap plastic!
