G10 liners / Fibre Liners

Several months back I had two knives that both had the fibre liners move after they were completed. By move I mean the liners must have swell by a small amount and so the handle had to be re-sanded to take them level with the handle steel again. Not sure why they moved but I suspect moisture in the shed they were kept in for around a month before they were sheathed.

My question is ....is this unusual or can it happen with fibre liners and how can I stop it please?

I then went over to G10 liners but the first set I did were bonded onto the scales with 2 Tonne epoxy/ black powder pigment but they were not secure and I could peel them off with ease. The scales were stabilised.

So what is the best glue to use with stabilised wood and G10 liners that will be secure?

Thanks

Without getting on my "epoxy" soapbox, I will ask this question.... how did you prep the surfaces to be glued? Proper surface prep is everything, especially when it comes to gluing dissimilar materials.
 
Regardless of the adhesive questions/process, I won't touch fiber liners anymore. They WILL expand, buckle and warp, especially if they get wet.
 
Apologies I didn't answer sooner but I always 'rough up' the surfaces and then clean with acetone and leave to dry.
I too am ditching the fibre liners as its just to much to risk/lose should they fail. What I am going to do is buy some blade bond extreme after contacting Andy on his site and also as a lot of liner material and handle material is expensive here in the UK I am going to have a go at making my own paper liners and also my own paper and cloth micarta. I took the plunge of stabilising my own wood for blanks and that was so successful I don't think I will ever buy another blank.

Hopefully the Micarta will be a success ))

Cheers
 
I am only a rookie but it seems if he coated that liner 100% it wouldn't move swell or anything because it would be in fiberglass just like micarta.
 
Rick, you're right, when the liner is coated solid with epoxy between tang to liner, and liner to scale you won't have any moisture there. What happens is the edge which is usually ground to clean up epoxy and scales around the metal tang, any sealing epoxy is ground away leaving a bare raw fiber edge that might can absorb moisture.

Never thought of that I just figured the fiber would soak up the glass and be solid all the way through thanks for the tip.
