G5
Dick,
Living in Florida I can see where the bubbles in the mix would not be a problem to you. For me it was a nightmare because I would be producing beautiful results for a long time then everything would go to hell. It took me 2 years to figure out that the colder temps were screwing me.
At any rate, thanks for your weighing in on your experience with G5. I talked to the engineering at West System today to find out the skinny on this product for our use. The website states, (quote)"Not recommended for long-term bonds subject to high loads or moisture". The engineer told me that that statement only exists only due to the fact that West System Products are generally used in the marine environment for boat structures. High loads are duration loads.
He did state that due to the resin formula that G5 is the strongest 2 part 5 min cure epoxy on the market. The compression strength is rated at 9600 pounds per square inch and the psi for pull off (bonding) when used as a substrate is about 1200 psi for most woods and aluminum.
At any rate he also stated that all tests are done over specific long term time durations and that in our pool cue application that we are only subject to Milli second shock loads from hitting the cue. Since over 99% of these shock loads are absorbed by the wood and core components of the cue, the load to the finish is negligible. As far as the deco rings getting loose, I am at a loss.
He also told me that you can mix G5 with 105/206, 105/207 to shorten your cure time on those products.
I like the G5 because it was always a pain in my ass to sand the thinner epoxies that you had to wait till the next day to sand. Then half the time I would burn thru while sanding and have to start over. With G5, I can put on 3 coats within 15 minutes and sand the next day and never worry about burning thru and starting over. G5 makes my production system process control repeatable every time.
