DIY weighted diaphragm stretcher (pic)

The Quad 63 coating is two layers, a white sublayer and then the grey coating. The photo is presumably of the application of the white stuff.

I've used a variation of the (I think) 'I Forgot' inspired inner tube stretcher,

An externally hosted image should be here but it was not working when we last tested it.


Using an open frame both sides of the stretched film are accessible.

Hello to all,

seems to be a stretching jig contest. So here is mine. Looks like the great brother from Arend-Jans jig - but it has more clamps on the short sides similar to the original 63´stretcher. This beast is two meters long and fills the room...all for my Quads.
