well took some time to do a test pour, this was for pour testing only, see how it mixes, how it pours, cures, etc....

i figured i would pour one set, one pure urethane no inset, then the other would pour with the 3d printed inset for validation purposes. want to make sure it will fully encapsulate the inset.

did my material calculations... firs was to put a coat of sealer/release on the molds, let set 15 minutes, then another light coat and let sit 30 minutes. mix up the urethrae, then measure out equal parts urethane Part A & urethane Part B. then mix them together into one mixing cup. then our into molds. i filled jut to the funnel so that there was extra material, i tapped and rocked the mold to make sure air was out and urethane was settled. actually mixed and poured nicely. slow and steady is the pace !!
