Intro
This is not as much about the actual blaster as you can vary that to fit your wants/needs. This is a write up on how I made mine but to also get this trigger design out there as it is simple, cheap, and the parts can be bought from your local hardware store. This is rev1 so yes it has flaws but I figured I would make this write up so others can make their own version and we can collectively from what we learn by making our own combine our ideas to make the ultimate blaster.

Materials
Trigger
1/4" x 3" carriage bolt
1/4-20m rubber well nut part# 83115 at Menards
Small spring(I just got this one out of my box of springs)
#6 O-ring
Body
3/4" Pvc
1/2" Pvc
3/4" T-joint
3/4" coupler
3/4" end cap
3/4" x 1/2" reducing bushing x2
1/2" 90 degree elbow

Tank/pump
1" Pvc
1/2" Pvc
1" coupling x2
1" 90 degree elbow
1" x 1/2" reducing Bushing
1" x 1/2" reducing bushing female thread
1/2" male threaded adapter
1/2" x 3/4" reducing bushing
3/4" 90 Degree elbow
Pump of your choice

Adhesives
Solvent weld
Super Glue
Hot glue

Other
E-tape

Cost
Depending on your pump between $14-$20

Time
Took me about half an hour to build not including cure time.

Tools

Minimum Requirements
Hacksaw
Sandpaper
Hobby Knife
Drill

Helpful Tools
Miter Saw

Assembly

This is how the blaster will be assembled
Posted Image
Posted Image

Body

Put one or your 3/4" x 1/2" bushing onto your T-joint and a 1 1/2" segment of 1/2" pvc in that.
(this picture is wrong don't put that 1" x 1/2" bushing on yet)
Posted Image

Drill a hole as centered as possible in the 3/4" T
Posted Image

Next cut 2 2" segments of 3/4" pvc and assemble on one side of your 3/4" T like so.
Posted Image
Posted Image

Put another 3/4" x 1/2" bushing in the T followed by a 1 1/2" segment of 1/2" pvc followed by a 1/2" 90 degree elbow. This is where you barrel will go. I like to use a hopper setup.
Posted Image

This is what you should have so far.
Posted Image

Now we are going to put the trigger on.

Its pretty self explanatory but for all you idiots out there, Assemble your parts like shown. (there should be an O-ring between the spring and the T)
Posted Image

Now push this assemble into the corresponding holes and screw the bolt into the well nut.
Posted Image

Yes its that easy!

Just in case I filled this hole with goop.
Posted Image


Tank/pump

Sorry no picture of this but you want to assemble your parts like this,
3/4" x 1/2" bushing.....in 1" coupler.....7" of 1" pvc in the other side.....1" elbow.....2" of 1" pvc.....3/4" x 1/2" female thread bushing.
Posted Image

All these parts need to be solvent welded together as they will be holding pressure.

Now to attach your pump to your tank if you used the same pump as I did. IF you used a different pump then use your brain and figure something out.
Take your 3/4" elbow and put a 3/4" x 1/2" bushing in one side. Then put a 1 1/2" segment of 1/2" pvc in that with a 1/2" male adapter on that.
Posted Image

These pieces also need to be solvent welded together.
Posted Image

Put some E-tape on the pump so it fits in the elbow nicely. Put a few drops of superglue on it and push it in as far as it will go.
Posted Image

Then put solvent weld to seal it off.
Use this
Posted Image

Wrap the threads of the male adapter in Teflon tape and screw it in. You end up with this.
Posted Image

You can now put the segment of 1/2" pvc from the trigger into the 3/4" x 1/2" bushing of the tank.
Pump it a few times to make sure it doesn't leak and you trigger works. If all works correctly you can solvent weld them together. You end up with this with your pump of choice on the bottom.
Posted Image

Ranges

With slugs and 14" pvc barrel with 12" of nested PETG I am getting 90-100 flat with 9 pumps. You can't pump it past 10 pumps otherwise you will break the pump shaft. So I guess that is an oprv of sorts for you. rev2 will have a built in oprv and an almost semi auto system that is optional.

Hey, look, I'm the first one to comment.

Anyways, I like it. It kinda reminds me of a giraffe...

Looks nice. Like a cheaper version of a JSPB. Cool!

I think it looks more like a gazelle than a giraffe.

Whatever animal gets the most votes gets that animal themed PJ on it.
ON topic: thanks for the compliments.

You're welcome! I like the overall simplicity of the system.

You should do an animal poll.

UPDATE REVISED TRIGGER

I was having sealing issues with the trigger and I thought it was just because they were poorly built but after building 3 more I realized that wasn't it. So I came up with a revised trigger design.

For the new trigger you need an O-ring. The one I used was from a broken hornet pump.

Here is the new setup.
Posted Image

Slip the O-ring on like so.
Posted Image
EDIT you are going to want to super glue the o-ring on, If you don not is sometimes gets stuck in the pvc so you can't fire it.

Bevel out the sch80 pvc. Here it is next to some non-beveled stuff.
Posted Image

Assemble like so.
Posted Image


I also filled this hole with hotglue.
Posted Image

It now seals perfectly every time. Next update will be with my finished homemade pump.


EDIT: Video update on it.

I LOVE this. I will be modifying my "land pattern airgun" to use this valve as opposed to the check valve in future. It's amazing.

Thank you arfink, I hope to have a few at the next MN war.

UPDATE
Upon further testing I realized sometimes the balster wouldn't fire and the problem was the O-ring got stuck in the PVC and was just sliding around on the well nut. The solution to this is to superglue your o-ring on.

I really don't suggest using super glue on an O-ring, it tends to shorten the life of the rubber. I'd suggest something more rubbery, like silicone, or even hot glue. I'm sure Goop/E-6000 would work just as well.

First off this is pretty cool, very neat design.

However, I'm going to need to hear an explanation from all the giraffe people.

I mean seriously, have you guys never been to a zoo before?

↓ I could see thinking that at first, I just thought it was crazy it was getting more votes after the much more fitting gazelle was suggested. I had to take action!

Sorry for the tangent, but it just struck me as a giraffe, for some reason. Apparently, other people agree with me, because "Giraffe" is winning by two votes. I think it would look more like a giraffe if the distance from the tee to the elbow was increased, but I digress.

Back on topic, I'd really like to see some pictures of a completed blaster with a pump...

That's real purdy. Looks like you've just re-worked the basic components of the JSPB design into a much cheaper to build homemade. I am seriously jealous.
