I recently asked for comments as the best way to glue a stack of 40+ brass and steel pieces together. Further to "Peter Fairbrothers" comments I thinned epoxy with IPA. This worked extremely well. It gave me plenty of time to glue the stack and the bond line ended thin enough to not give any additional thickness problems.
Some may have guessed what I was doing, the results are shown at
