this is my first time using fiber spacers and i am wondering what the best methods for assembly are and what type of expoy is best.
i am using the std. fiber spacers that you get from any knife making supplier and carbon fiber handles. i just tried to use my standard 2 ton epoxy and after it dried the spacers just peeled off of the carbon fiber. should i sand both surfaces? any help would be great.
thanks

Sand them, and if you can sand blast them in a cabinet that's even better.

Then the surfaces have to be clean! Liquid ivory works wonders, but a solvent like paint thinner works well...I usually use both.

With the scale to liner surfaces being so flat, it's pretty easy to just use a cyanolyte adhesive. Locktite, superglue, etc.

Then once the scales/spacer is glued up to the tang and pinned or riveted on, it can't go anywhere.

Just how I do it

The only thing that I may add is that after you rough up or sand both surfaces (scales and spacer) I clean with acetone to get rid of any oily residue.
 
It's quite possible (probable) that your carbon fiber material had mold release agent on the surface. I'd use acetone. That stuff can be pretty persistant. Of course, you could also sand off a little of the surface and that would work even better.

I agree with all the above, make sure that the scales are clean before glueing. I use superglue to attach the spacers to my scales and then expoy the scales to the blade and screw or pin the scales. Give it a try, go
luck.

Get rid of the epoxy and use daps weldwood contact cement. It's the strongest bond you'll ever get between two flat surfaces. Just make sure both are clean and scuffed up some and apply a thin coat to each piece.

Take care!! Michael

Always think of your fellow knife makers as partners in the search for the perfect blade, not as people trying to compete with you and your work!

Try devcon 5 min. epoxy. It seems to adhere a lot better than the 2 ton stuff. Clean with acetone and rough up the surfaces and clean again. spread a thin coat on both pieces and lay on wax paper and weight them down. Next day glue to tang same procedure.

I would highly recomend Conap epoxy. You can get it from Sheffield's. It's what Bob Loveless uses. I have used it for years. It's easy to mix up. You don't have to weigh it out, or measure two parts to one part. You just squeeze out two equal lengths from the two tubes, mix and use. It works great. I have used other epoxies, but in my opinion, Conap is the best.
 
That conap stuff is the same they use on golf clubs. Can you imagine the torque that stuff goes through at the end of a chrome plated shaft? The ONLY thing holding that head on the club is a thin layer of epoxy. Gotta be good enough for what we're doing....
