When the bow is under full tension you will notice there is 1-2mm gap between the picatinny part on the back and magazine. Here's is the most likely reason you are having this problem. After sanding with a finer grit finish the part with soapy water and dish washing metal wire for scrubbing the pots (clean one) You will be surprised trust me!

Tomorrow I will re upload all of the files with the suggested print orientation. When installing a bow, make sure there's no play and that it is evenly distributed. Work the pistol mechanism many times before attaching it to aluminum.This part is the hardest to get working at first but when you start shooting it gets better by use. Pistol body and magazine sides are ok at 35-50%Small mechanical parts should be at lower layer height, 0.2 or less at lower speed to avoid sharp angle deformation.Īlso do not tighten pistol body's sides to much for start until the mechanism sets in place by use. Levers, carriage, front core, flat magazine base and string stoppers take the most beating.I print these parts at 75-80% The parts that take most stress should de infilled at 65% at least. I suggest measuring where to drill with a caliper rather than using printed guides. I optimized the holes since they were a bit tight and did some polishing on mechanical parts.Īlso at the last page of guide there are measurements for drilling. īefore starting I advise to re-download update 4 at Cults. Hey, thank you ! I hope you will be successful at completing this project.I just finished my second and it wasn't an easy task.

None of the adderini files were measured in any way or. The Adderini has two part lever system, Baraba has 3, two side levers and one main lever reinforced by 100mm M5 bolt trough it's core to prevent bending. The magazine pusher has a different way of opening and locking. The latch holding the lever locked is the only part having the totally same function as in adderini, owning this to it's basic and simple function I didn't want to "invent how water" and complicate it.
