Ozcan, GRBaker and NicholasT,

Thanks for the comments. You all have good points. I have had older fibreglass stuff go brittle and other stuff not. Before we start this project, we had inspected the glass. It seems to be fairly flexible. Should be fine.

Actually, what I found also was that the joints between formers and the fuse went brittle. It was epoxy. Lately, I have been using poly-urethane glue to put in formers and bulkheads. It seems to work better over epoxy. And the joints maintain a bit of give. Not brittle.

Like the scale wire gear.

Thanks,
