Baaaack in the day, we worked on an Angel Pump Kit for LCD angels
Required:
Venturi Bolt
9v Mod of some sort
Functional LCD Angel
Machining the Roto-Breach (slot)
Machining the Body (slot, drill/tap)
1 Setscrew (dog point preferred)
Kit includes:
Anodized Aluminum Guide Arm
Anodized Aluminum Guide Bushing
Stainless Steel Pump Arm
3D Printed Pump Handle
Delrin "Hammer"
We are working on basic machining info next
Basic idea is:
Mill slot in Roto-Breach
Mill matching slot in Body, careful to avoid the airtransfer tube
Drill/Tap Setscrew hole in front of new body slot
Use a Setscrew (dogpoint preferred) to capture the pump hammer from overtraveling off the guide rod
Venturi Bolt keeps air flow aligned, while bolt is in "pump mode"
9v Mod required, because pump kit goes in the battery tube
