Bsi 5m Epoxy

Honestly, I like medium-viscosity epoxy, need more time for cure but is more flexible and more resistant with vibrations.

I am work with 20 minuts epoxy in this moment and I dont like because it is more fluid and this is bad because it does not fill the gaps/holes in a pin istallation. I think that 5 minutes epoxy is fluid also.

This is my opinion but I might be wrong.
 
I studied a book on adhesives about as thick as an encyclopedia , required for golfsmithing ... The faster the cure the less elasticity , or the more brittle the bond is ... For bonds subjected to stress of impacts or high loads , a slow cure is best ... I use an epoxy used for bonding steel in high stress conditions which is way overkill for cue construction , but I don't have to worry about failure, makes for a rock solid bond ... The quick cure stuff is fine for certain applications but not near as strong or flexable as the 24hr ... :cool:

And it comes in a bottle instead of a syringe, it's not good enough for major stress area imo.
24-hr is best imo also.

Eric,

Very informative thread. Good food for thought!

I have switched from west system (not G5) to gorilla glue for coring. I now wonder if west is better than gorilla due to slow cure and the soaking effect that was also posted here? Or maybe the soaking effect will be bad and create voids? The gorilla glue expands to fill the annulus and that is no doubt the way to go? I am still on the hill on this issue. I guess I will stay with the gorilla as many top cue makers have used it for a while and say it's very good.

If anyone has any thoughts on this, please put your 2 cents in.

Problem with 5 min Epoxy

I have a problem with this 5min Epoxy by BSI yesterday
I installed a ferrule with this product and the result was disastrous.

I mixed 1 / 1 epoxy and let cure 2 hours before working ferrule in a lathe, mixture seemed very liquid but I provide to see the result after 2 hours so when I working with lathe my ferrule flew:grin-square:.

finally, very dense cyano finished the job (in a house cue)


I think that mixed 1/1 not is correct, any advice?
