I’m very happy with this trip bar geometry, most consistent results yet with repeatable release timing. It’s probably a little late but working and I’d rather err on the safe side.
Need to finish the CAD for the metal trip bar now that I know the starting length and get that coming. Surprisingly the plastic held up, much better than expected.
Also need to start over with a fresh hammer and try and get a profile that works without welding. I had the hammer good with a big ass shark fin welded on but I found the limit trying to trim it down.
On hold. Printed trip bar version works but I had issues with the first metal bars, so that needs to be revisited. The metal is thinner than the plastic which affected release a bit.
It’s a fairly involved project and testing/development is slow going on my own, plus mag dump testing 308 gets expensive fast.
totaly get that. when you get to the point of needing/wanting someone else to help with testing, id be happy to burn through some 308, in the name of progress.
