I'm using some ideas i've seen from other Pumpsnap videos, just throwing that out there before we start!


Materials:

1/2" CPVC

1 1/4" OD, 1/4" ID metal fender washer

1" long, 1/2" OD, .194 ID (get a bigger ID if you can find one) nylon spacer

And some random bolt that fits your washer.

Start off by hammering the spacer into the CPVC:

Now drill out the inside of the spacer so it's possibly to start threads for the bolt. I didn't feel that it was necessary to use a tap, so I started assembling it:

I used nails to hold the spacer in, then used my bench grinder to smooth it all down:

Pretty simple, don't you think?

I will edit this post if anything breaks. ;)

I would tap the inside of the nylon spacer and use set screws instead of the nail, but otherwise, Nice job.

Once I had the bolt it, It already made its own threads. And I used a nail gun so if anything breaks, it should be the metal washer or the spacer :P

You didn't mention what the point of doing all this is. You still have to put a coupler on the end of your pump and a bolt on each side of it.

Its just an a alternate method of securing the either metal washer or polycarb disk to the plunger rod.. Fairly simple

As BBV said it's just an alternative method. Instead of buying the (nylon?) rod you get from McMaster, you can get the spacer for a dollar AND you get it locally!

And I don't think anyone needs a guide for putting bolts into a coupler.....

Something else that you could do, it put a screw through the nylon spacer, going the opposite way, so that it cannot come out, and then put a nut on the other side to hold the washer on, I've had screws slip out even with the hole tapped to the right size, and this is a good fix for that.

Good idea. Thanks

These are from my 'HomeWrecker' and 'Multiple Orgasm' write ups. You can also use 1/2" PEX and drywall anchors. The anchors bite into the PEX extremely well. The result is a very cheap, extremely light and incredibly strong plunger rod.

This set up has never failed me. Even with a 28kg (~62lbs.) spring load.

I was linked to your guide before I made this. Thanks.
