Details for my PulseStrike. Due to the ID(inner diameter) of 1.25" PVC being 1.38" and the OD(outer diameter) of 1" PVC being 1.315", 1" Bushings, when the large ends are shaven down, will fit nicely inside 1.25" PVC while still having a tight enough fit to keep a good seal with the .675"x1.375" U-Cups. In fact, in theory I would be able to just use 1" PVC and the two U-Cups to form a perfect seal without the CPVC guide rod if the K34 weren't such an issue. When I do get around to this, I'll definitely test this with just the cylinder first to see if it'll work. As I noted before though, the CPVC guide rod does open this tank design up to a wider variety of valves, including backpressure valves; I'm excited about this as backpressure valves are ridiculously powerful and efficient on their own, nevermind with this as a tank. Also, I'm considering buying clear PVC when I shop for this project; not only is clear PVC just badass, it's pressure rating is within safe ranges, and it'll allow me to watch the tank in action, providing useful testing data.

Edit: So, my bad, this is what I get trying to work with decimals at 4am, but everywhere that I've written .675, there's a really good chance I mean .875.

Edit 2: I've now discovered that the use of CPVC and a second size of U-Cup is completely unnecessary. The .875" ID of the U-Cup is perfect for .5" PVC, if the guide rod is needed. This means I can just use the U-Cups glued onto .5"x.75" bushings shoved inside a piece of 1" PVC as the piston.

Continuing my trend of thinking of ideas more than I do anything useful, I've now decided I need to work on Buffdaddy's Homemade Pulsestrike design. I'm designing it around a 1.25" PVC tank and my awesome K34 spring. For the piston, I've got 1"x.5" reducer bushings with internal ridges sanded out so they can be placed back to back using a piece of .5" PVC. This piece will stick out both sides of the bushings and will have a .5" coupler on the back side and a 1/2"x.375" reducer bushing on the front compressing a 1.25" skirt seal on either side. Instead of just using spring spacers like Buffdaddy, I'm fairly concerned with the K34 behaving under compression, so there will be a .5" CPVC "guide" that the piston will ride on and will help to hold the spring in place. To seal around this, I'll be using a second size of skirt seal glued to the front of the .5"x.375" bushing and will seal around the CPVC guide. This will introduce a second sealing surface into the tank, but I feel that it's worth it to ensure the spring will be stable. On the back will be a 1.5" threaded coupler so I can simply screw on a 1.25"x .5" bushing to hold the CPVC in place. On the front, a 1.25"x1" threaded adapter to hook my solenoid valve to. This is kind of an awkward tank to use as the only valves that can be used are ball valves or check valves due to the inner workings of the tank. Actually, just now thinking about it, the center CPVC guide means that a pin or backpressure setup could be used, giving more that just a single reason to consider the center guide. I'll try and have somewhat decent drawings up sometime with measurements and part numbers for anyone interested.

Update: kinda weird being the first reply, but I got the end cap off the pump

It took several hours of tearing at it with a razor knife and several pairs of pliers, then I finally boiled it and it pulled right off. Also, the pump shaft is threaded on both ends and the pump head is just screwed on, so if the pump head fits in 1" PVC like I think it will based on sizes, it would be easy to just thread and replace the shaft with something longer.

As stated in the Concept Thread, I recently came across a $6 pump on ebay that seemed like a good deal for an obvious knock-off of higher quality bike pumps. After ordering one Tuesday and receiving it on Saturday, fairly quick shipping on the seller's part, I've now had a chance to look at it and somewhat evaluate it's place in Nerf modding and homemades.

As it looked fresh out of packaging.

Not too shabby looking, obviously a visual knock-off of higher quality bike pumps. In it's closed state it's 12.5" long, and 20.5" fully open, giving us 8" of stroke with a 1" diameter tube, netting us approximately .785ft2 of pump volume.

The handle, while feeling pretty comfy for my large hands, is actually flimsy and comes apart by simply removing the red pin. The entire handle can also be unscrewed from the pump shaft, which I'm happy to report is metal. This means that any number of different handles are possible to use, provided it uses a standard thread. If not, then it shouldn't be too much of a hassle to simply cut new threads that are standard.

Here I have the top cap removed to take off the piece used to keep the hose in place. A word of advice, avoid removing the pump head from the tube. The o-ring is a snug fit to the tube, so it's quite the challenge getting it back in.

At the bottom end, you have the hose connector that can be unscrewed easily. The bottom end of the hose is firmly attached to a piece of plastic within the cap there, so I don't see it being feasible to use that cap and adapter. You could cut that hose, shove another piece of hose in the elbow there and epoxy it in, then put the cap over it to ensure an even tighter fit, but that seems like a least-effort choice.

This is it in it's currently stripped-down state. I haven't gotten the end off yet, but I'll wait and get a friend to hold one end of it. Seeing as the tube is just over an inch in diameter, it should be easy to shove it into a 3/4" fitting or piece of 1" PVC, then have plenty of connectivity options. Also, the holder that comes with the pump appears to be a snug enough fit to hold the pump to something, but I'll have to test it while pumping up something to be certain. Overall, I can see this as being a versatile and useful pump for the $6 price tag. I'd definitely prefer this over my McGregor pump I used for my EPVAT; the tube is smaller, making higher pressures easier to pump, and it feels overall more stable to use, probably due to a 1/4" thick pump shaft.

I've never even seen those things but they look as if they would provide an excellent seal.

Me neither, just found them while looking for a source of beveled washers on Amazon as it's become my new go-to for almost anything.

On a related note, I noticed an old thread on NH where BuffDaddy was using the same 5/8L beveled washer I use for a front seal as the rear seal on an air tank using a 1/4" "pin" just like mine does. I had noticed they were a snug fit on the threaded portion of the bolt that I used, but I had never slid it further down. This basically means that I could "mirror" my front seal using the beveled washer and o-ring to the back of my EPVAT, thus eliminating the need for the brass bits on the back, reducing both size and price of the entire tank/valve assembly. It's almost ironic because I had begun sourcing polypropylene 1/2" x 1/8" adapters to replace most of the brass, but this is a much cheaper solution.

Now, for the unrelated note, I found and bought a fairly cheap bike pump that I think has the potential to be versatile enough to be useful. The handle is threaded on meaning I just need to find the thread size and I can use whatever I want for it, and the top has a cap, so if the handle rod seems too flimsy, it should be fairly easy to replace. I guarantee that the tube unscrews from that base, so I should be able to just glue it into a bushing and have connectivity options. Lastly, even without needing to modify it, you have a decently long hose that can just connect to either schrader or presta valves, 1/4" threaded versions of which are readily available, meaning this should be able to just be zip-tied onto anything and work with minimal effort.

Decided to get this thread rolling again since school gives me more time to think than it does to actually work on S**T. Considering some of these to see how they work verses faucet washers in a new version of my EPVAT. Seeing as my EPVAT seal was a conical surface touching an o-ring, the sharper angle on the cone should offer a similar, if not better, seal.

*Gets cat.*

But did you get a cat before or after the PETG? This is crucial.

Before... What is going to happen Yks?

Uh oh... reported
