Scale adhesives

Does it matter the color of the epoxy? The 2 ton at the store was grey colored and I didnt think that would go well with my black micarta scales.

As an adhesive, the clear works just fine.

I'm sure there are many epoxies that will work well. I have heard or read somewhere, however, that 'shafting epoxy' which is used to attach the heads on golf clubs, is an excellent choice for knife scales.

Shafting epoxy is very shock resistant but is designed to release at about 300 degrees F. This probably is not an issue but I thought I'd mention it.

I would suggest 2-part epoxy adhesive.

I agree. You can buy two part epoxy in different formulas, usually denoted by their setting time. The longer the time, the stronger the bond. 90 minute epoxy costs more than five minute epoxy, but is worth the few extra bucks.

As other posts mentioned make sure the surface is prepped before starting. Make sure both bonding surfaces have been slightly roughed with sandpaper. Wipe surfaces to be joined with acetone (test on any synthetic surfaces for compatibility). Apply a thin coat of epoxy to each surface, join the surfaces, wipe off any extra immediately, and clamp the handles firmly.

Now, walk away and leave it alone for at least 24 hours.

Final caveat: If it's cold outside, take the knife inside while it cures. 90 minute epoxy does best at room temperature, on well prepped surfaces.

My wife is far sighted but she can out sniff a blood hound. She can smell it up stairs if I open my tuff cloth pouch down stairs If I brought my epoxy to cure inside the house, my honey would be ever so cross with me. It also may be a little toxic. My step son will well up like a red tomato at weird things due to anaphylactic shock. We keep an epipen for him at all times. Maybe use a space heater in the garage if needed. BTW, thanks guys, I needed all the good info you gave, I am ready to form handles on my first knife. Now, if I could only get my fingers off this durn keyboard and get to work!!!!!

Question: If my handles are oak, other than sanding and I keep my fingers off the glue side, do I need to use MEK or Acetone? I think you are referring to Micarta and other non woods, but want to make sure.

Thanks,

I use acetone, from auto body stores, not fingernail polish remover.

Golfsmith shafting epoxy is the best I've found.

During this part, always use disposable latex gloves.
