As we finish up the last of the August batch of launchers a change is being made. Due to some recent problems with triggers, a change is recommended. In the past we recommended glueing the trigger. Long ago we used epoxy, then some time back we changed to CyanoAcrylate (CA or Krazy Glue). This glueing does not work consistently – sometimes it holds well, others not. Combined with occasional problems with the triggers, and the problems of getting the assembly apart when glued, leads us to this: We’re not going to glue the triggers on production launchers starting today, and we recommend against glueing them. The alternative is to use teflon tape in the threads. This seals well, and leaves the trigger assembly serviceable. The downside is that the trigger can move around if forced. This is not a problem, though it can be annoying. We have a better solution – a strut to prevent the trigger from rotating.

I tested a launcher destined for Sweden today, from the last batch. At 40 psi the ball went so high I just about didn’t get it back. Most of my Field Day launching this year was under 50 psi, and that was with a CSV17!

NOTE FOR HOMEBREWERS and KIT BUILDERS – the Harbor Freight (newly manufactured old style) trigger valves are not doing very well. Most are marginal flow-wise. We have a few old type valves in inventory but will have to do something different soon. We shipped some of the newer (bad) HF valves before this was discovered, so make sure and test your launcher BEFORE CEMENTING THE TRIGGER JOINTS so it will be easy to swap out bad triggers. 

Thanks for your patience,
