I've been using Loctite Depend 330 and liking it. Simple to use, no mixing and fast set time compared to similar strength epoxies that you mix. If you're after a faster set time this might be an option for you. It's almost like a CA in that you do not mix it and then apply it. You apply it to one part, put the activator on the other and put them together, at that point you've only got a very short time to get things settled and clamped so it's not for fine positioning. I use it in conjunction with a pin, tube or bolt and generally make sure they would work fine independently but are not so tight I can't get it all together quickly and clamped. I worry about peening the pins or any belling on the tubes later.
