Anyone using the above 20 minute epoxy? i bought some a while back but had a lot of failures not only on pen blanks but also on other projects. Never had this problem with Stick Fast.

Yes I use it all the time. In fact I just threw out some old stuff last month and I always date my bottles and is said Nov 2011. The hardener was actually starting to cristalize.
If yours is fairly new and you are mixing the correct amounts then it's possible you have a bad batch.

I use the bsi 15 min and 30 min varieties. Never a failure. I suspect old or defective batch or improper mixing - although the mixing ratio seems pretty forgiving

BSI 15 minute is my favorite epoxy. No failures since I started using it.

What is the temperature in your shop when you are gluing?
BSI 15 minute recommends above 65 degrees.
The 30 minute recommends above 70 degrees.
The 5 minute is the most forgiving. They say it will cure down to 40 degrees.
Just a thought. You are just a little bit south of me, and my garage shop gets pretty chilly right now. But I have no idea where your shop is, or if it's climate controlled, so take it for what it is worth.

Also with the failures are you allowing for a longer cure time. Occasionally folks will think that 15 / 30 min epoxy means that it's cured in that time.

Over the years, I've used a LOT of BSI epoxy on high power rockets. 5, 15, and 30 minute. Never had a problem. On pens, I use 5 minute almost exclusively. The only time I use a longer cure time epoxy is if I'm gluing up blanks for several pens at once. Lately I've been using Devcon 5 minute from Lowes, just because it's convenient to pick it up there. No problems with it, either. But like Dan said, 5 minute epoxy does not cure all the way in 5 minutes. I've turned within an hour with success, but if it's an important project or expensive blank, I'll wait longer.
