Thanks for all the ideas. I really appreciate the helpful nature and
experience of this group. I most certainly will be doing materials testing .... the first few ribs were going to be sacrificially tested anyway .... finally a use for a teenage son and a Bowflex!!!. I had tried syringes (from a photographic chemical supplier), but the epoxy seems way too thick to dispense accurately in really small quantities by this method or by pouring. I have some 80 year old chemical balance scales that are good to .01g .... but goop management seems to be the limiting factor. The glue that I am using is called "Hexcel" by Aircraft Spruce, described as similar to T88 and the 'slow cure' version seems to have a great pot life. Thanks Steve Dennis Johnson wrote: "steveukman" wrote in message oups.com... I am seeking advice about mixing and storing epoxy. For 15 bucks you can buy an electronic scale on EBay with an accuracy of a tenth of a gram that will allow you to mix tiny batches of epoxy. Personally, I wouldn't feel comfortable with using previously frozen, mixed epoxy for an airplane unless the epoxy manufacturer okayed it, but I'm a coward. My advice is to get an accurate scale and only mix as much as you need. By the way, which epoxy are you using that has a 2.5 hour pot life in the Texas heat?
