I got my One Stroke check maker yesterday and my .014 aluminum today. Mine is for .44 gas checks. Started out badly. The 1st or 2nd check punched gets stuck on the bottom half of the die. I have to use a steel pick (similar to a dentist pick) to get the thing off. It's hard to notice the check stuck on there and any subsequent checks punched on top of that stuck check are sheared off with no sides. I've sent emails to Brian and I hope he backs this one up with one that works. I tried lubing the dies and aluminum strips with WD40, which did nothing. I heated the strips to around 575F, and that did nothing either. I believe the mandrel inside the bottom half that the check is formed around is either too thick or needs chamfering. I would have hoped that they tested these things before shipping them out.
