If your pneumatic launcher makes a ‘honking’ type noise when you trigger it, this is an indication of low trigger airflow. It is also a sure sign of an underperforming launcher.
The Harbor Freight air dusters we use for triggers sometimes exhibit this problem when the valve is overtightened into the frame. Loosen the nut around the pin that the trigger pushes on about 1 turn. There is an O ring seal there, so this should not cause it to leak. The honking should cease and the performance increase.
In the past this happened very rarely (only once that we are aware of), but with the new batches of parts it has happened at least twice recently.
The other problem we have seen that causes inadequate trigger flow is the installation of the outlet jet on the air duster. This outlet jet should not be installed to allow the best trigger flow.
We’re back from the Pacificon convention. We had a good turnout at the presentation there, and lots of folks talked to us at our corner of the wife’s Cookie Lee table. Thanks for all the good comments and suggestions. We had a good show and there was a lot of new interest. We also have a couple of new speaking invitations to local clubs.
The next event on the calendar right now is the River City ARC meeting on wednesday the 8th of November. They usually have meetings on tuesday night, but this one is on wednesday.
Now we will work on the backlog of orders. Three are ready to go out, but there are several more in the queue to start on, and we’ve heard that we need to bring some to the meeting Nov. 8.
We are preparing to depart now for the SJVARS Harvest Hamfest (where we have an Early presentation), but in a few weeks we will be going to Pacificon. We have a session scheduled, “How to Build a Pneumatic Antenna Launcher” at 10:45 in Salon F. On the Pacificon web www.pacificon.org, it has been shortened and the word “Launcher” left off. Hope to see you all there! We will also have a corner of the wife’s Cookie Lee jewelry table in the hallway.
