MWC:S - Homemade

[Silence]

Sounds great! Remember that if you can get a couple dozen more tubes on there, then the power will really increase. What do you plan to use rubber bands for? They are poor substitutes for the actual layering since they are cut into narrow strips, and thus won't stretch much in the direction of the tubing.

Going to layer them on where the valve on the inner tube is. So far, I have run out of inner tubing to put over here, so rubber bands would be a fast, quick solution to stop this section from bulging.

EDIT:
With a new nozzle(made out of a pen tip, so the nozzle was perfectly circular) I got 14 feet of range! The nozzle makes about 5 feet worth of difference. This is with two layers of inner tubing, so when more comes I should be able to get my goal of 20-30 feet easily.

I like those pictures, and thanks for getting them up! The design definitely beats out XRay's homemade in terms of creativity, which is quite a feat. However, I'll only trust it once the inner tubing attachment system works for 20-30 layers of tubing. Also, note that the final range could be as high 40 feet, but I'm not sure. How much did you let the tubing expand? I'll bet it took up a lot of space in the end...

Anyway, it's nice to see an unorthodox design with such impressive results, so keep up the good work! There's a ton of potential here.

And just for the record, I seem to have made the most promises and the fewest completed ones in terms of getting pictures up. Seriously, I am having trouble with the camera drivers--they're only on a different computer.

Neat, but this is definitely overly complicated and it shows in the performance.

Female garden hose couplers are extremely bad for flow. They really obscruct it. Eliminate those and you'll have slightly increased range. More layers can't make up for flow obstructions like that.

But of course, I'd really doubt you can get range higher than 45 feet even with my improvements. There's simply not enough flow in the vinyl tubing to allow for higher range unless you put an extreme amount of layers on, which wouldn't allow for the water gun to be filled by the hose. Remember, the hose can only fill something as powerful as it is at best.

Since you live in New Zealand, if you're going for another water gun in the future, I'd suggest following this guide by a forum member who lives in New Zealand also: http://www.geocities.com/waterwarrio...l.net/article5

Imho, it's not designed for performance, it's designed for field use. It really isn't complicated - everything clips together and the gun can be built completely within 30 mins, 15 if you know what you're doing. Nothing more than a screwdriver and some scissors are required for tools. If anything breaks, as long as you have spares on hand, it can be replaced in 30 seconds.

Note I said 20-30 feet, I wasn't really aiming for 40-50 feet. If I wanted that, I'd build something out of PVC(Which is ridiculously hard to find and expensive here!)

I worked out a new technique of attaching the valve which works perfectly - no leakages. The gun is completely leak proof now. I'll upload a vid of me building it(Sans the innertube, because I'm too lazy to slap it back together), as well as "pumping" it and firing it. It also only costs approx $30 NZD($20 USD) at most, less if you implement a cost saving design I'll be showing off after this is done.

EDIT:
I managed to get another inner tube from the local bike shop. With 3-4 layers of inner tube, I got 21 feet of range! I'm likely to add another one or two layers on tomorrow, then call it complete, aiming for 30 feet. It takes a lot of work to keep putting on the layers - is there any easy techniques?

This weapon is not suitable for use on the battlefield in general waterfights. The problems I have found are:

1. Lack of shot time(Could be repaired by using LRT.)
2. Lack of range(Not so big a problem, it's about equal to all commerically available waterguns. The scout role does not need range.)
3. Awkward handling - This gun is not really holdable. It's very floppy and tends to force you into odd positions.
4. Doesn't have a pump, so you're kinda stuck with being close by to taps.

though it seems to be composed of different parts, there is a design that is similar to the MWC in this video

i'm playing a game like this, so i'm trying to figure out a similar design (ben's helping me though ). anyway, the design in this video looks like it would probably be easier to use....

[Neongreen]

That design is actually very much identical(Minus the pump) to the V3 version of the MWC:S. However, it's even harder to hold, with only +2 feet of range.

I am interested in that game though, I might end up running something similar in NZ
