Looks great, i like how simple the mechanism is with just the fitted metal collar and catch spring.

Time to check out hobby stores for metal rods and collars!

I really like this, but what purpose does the washer serve? What size is it? I am not being critical, I am just curious.
This seems to be basically an american version of SgNerf's catch. If that is true, could you substitute 3/4" CPVC for the shaft collar, and use 1/2" CPVC as a plunger rod?

I would like to know where you bought that shaft collar and the part number.

[Mod Man]

SG, Thanks, the T location is directly from yours, I had been wrestling with incorporating it into the back end of the plunger tube when your catch Tee Post breathed new life to allot of frustration....Thanks

NG416 The 1inch fender washer provides a platform for the catch spring to seat against. That spring in turn produces the pressure for the catch to engage the notch in the plunger rod. Thanks for the question.

K9 WTF! D.B. Cooper, hijacking is a crime.......lol
I don't know exactly what your up to here........but. Please go find some other corner of the forums to piss in.

A few questions:

Wouldn't it just be easier to use a 1/2" ID shaft collar?
How do you get the washer in the tee, and what keeps it in place?

Hey Drax, 1/2in I.D. shaft collars are about a 1in 1/8th in outside dia. to big for the i.d. of the 3/4in. pvc I'm trying to fit. On larger dia. pvc you can use the 1/2in. shaft collar and no need for drilling. The washer fits the T just snug. I haven't had any prob of it moving around on me because its under constant pressure from the spring. I may put a drop of hot glue in there if need be but sofar no prob. Thanks for the question and if you have any others let them rip. Later, Mod

I'm just confused as to how the washer gets in the tee in the first place. No matter how I visualize this, you couldn't get the washer in there, since all 3 ports have the little ridge in them that I presume the washer is resting on, and if it was small enough to fit in, then it'd just get popped out the bottom. I dunno, odds are I'm just overthinking this.

Yes the washer just fits into the Tee resting on small mold seam, not yet into the junction where the t is formed. 3/4in nibco sched 40 Tee and a 1inch o.d. fender washer, check it out at your local hardware. I think I may do a small write up in the next couple days. Mod

That's sweet. I really would like to see a write-up for the whole pump action blaster.
