The __jrP4__ - Junior Portable Pnuematic Projectile Propogator

Step 5 Final assembly

Almost there.

1) First screw (F) and (G) together.

2) Screw the (F-G) combo into (E) very tightly (so you don't have any slip left when you seat the diaphram).

3) Wrap the 1 1/2 MT of (E). Lay the diaphram in place and screw the (E-F-G) assembly on until it just sits with the diaphram.

4) Before you attach the pump, test it out. I put about 20 lbs into it, shoved some tissue in the barrel and pushed the trigger.

5) Attach the pump and secure it to the chamber. I cut a small length of PVC, indented the ends to match the chamber and the pump, held it in place with a couple of zip ties and wrapped it all with electrical tape to keep it in place.

i have seen it many times, and still dont get it. what is the PVC ring with the blue ring? what is the blue ring?

[dschwant]

Do you mean the roll of teflon (R) tape - used to seal the pvc thread fittings?

[SheenJones]

well is that the blue thing? what is teflon tape for? and why is it in that peice of PVC?

[dschwant]

Yes, that is a spool of teflon tape. The white piece around it is the cover for the tape spool (plastic but not PVC). Anytime you put a PVC threaded joint together, you should use teflon tape. The tape should be wrapped in a clockwise direction on the male fitting - to match how the threads will grab tape. They make special tape (yellow?) if you are using PVC for gas (natural or propane), but for normal water or electrical PVC the white tape is the thing to use.
