I delayed my departure for Quartzfest to ship the remaining assembled launchers from the current batch which were nearing completion. Unfortunately they all failed pressure testing and it will require more time to remedy than I have now so it will be addressed after I return from the trip. It appears that the latest batch of pressure relief valves is leaking. I’ve never had such a high failure rate for pressure testing. The kits in this batch which were already sent out used safety valves from previous inventory which did not have the problem. The pressure relief valves can be disassembled and cleaned and we have some instructions for doing that online if you find a similar problem. Hopefully a cleaning will work here, otherwise they will all have to be re-ordered and replaced.
I hope to be at Quartzfest in a couple of days, it is a long drive. Hope to see you there!
My apologies for the lateness of this batch, it has stretched out longer than expected. We plan to start another batch later next month. They fill up fast so make sure you are on the notification email list. Drop me an email if you need to be added to the email list.
