Progress on the new LpLs. I'll edit in pictures of the other two that are bent and ready to go in a bit.

My first Plusbow! I call it the Ported Piston Plusbow, or PPP. For an explanation of the name, check out the plunger head.











My changes:

• HDPE grip
• Solvent welded front bushing
• Longer screws for everything
• Extension spring instead of ghetto rubber band
• Ported Piston plunger head
• Plunger padding
• Smaller holes at the sideplate connection points

Velocity (max) measured with a 12'' slide breech and 1.25'' #6 slugs. Gonna try to Chrony with some other barrel setups and update with some Chrony pics.

The printing is going well.

Here is my first home made SNAP. I used TheNerfOmania's tutorial to make it.

The Number 2.1, a mighty fine rainbow-pump.

Needs some fine tuning that will be implemented in the Number 3.

[Joe Espinoza]

The roboman 2.0 crossbow with replaced aluminum stock rods, plunger rod, and full aluminum plunger tube.

Snapbow MK. V

[kbk652]

This is my homemade version of the maximizer, It works very similarly to the lanard maxshot, the internals are aluminum and the red is plastic coverings. It has a little under 6.5" of draw on a 2"od plunger tube.

Big and Little brother. Writeup is done on the big brother. Will be making an overview of the Rainbow-Bullpup-Pistol-Carbine shortly.

TCD style Snapbow

I was experimenting with different types of priming, after awhile I built this out of random Snapbow parts. It has a full [k26] spring

The ever-refined Extension Spring Blasters. Coming soon.



Our new printer



Capable of printing in high temperature materials, such as Nylon. Auto bed-leveling modification also installed.



Since then I've redesigned the X carriage.



Vertically printed Purple Catch

This my new design of the Aabow. The only real difference is removable bow limbs for easier transportation and storage.



Here's a picture showing the limbs removed.



There is one solid piece of 1 inch pvc running through the main tee acting as the riser for the bow arms. The 1 inch that's exposed was heated with a heat gun until soft and the bow arms were inserted to form it to the arms. Once they cooled the bow arms can be pulled out. This design also used heated and flattened pvc bow arms which have a higher draw weight and faster reaction time. I've used the same technique to make arrow shooting bows. The bow arms wont come out when flexed, only when pulling straight out to remove them.



This diagram shows how the bow arms hold themselves in. yellow - tee. green - 1 1/4 inch to 1 inch bushing. red - 1 inch pipe heated and formed to the bow arm. Black - bow arm.

The bow arm has a tapered shape that keeps it in place in the pipe. The pipe will flex open enough to pull out the bow arm when pulling straight, but wont allow it to pull out when flexing backwards.



Here's a picture showing an arrow shooting bow made using the same flattening techniques, the current design of the Aabow, and the original design (dracbow). This design is almost a full foot shorter than the original, but performs on par or better than it. This is because the flattened limbs had a higher draw weight and faster deflex.

Everyone should buy Ryan out of his blasters because they are too good.




The trigger is extremely nice, the catch is satisfying, and the blaster shoots very well. The handle is one of the most ergonomic I've felt. I've never liked a pump action blaster before this one.




It's also the length of a barrel-less +bow with its barrel/hopper on, which means it's very compact and easy to wield. If you come to Armageddon you can try it out.

I finished this blaster shortly after MakeItGo came out with his bullpup design but finally play tested it this weekend in Pittsburgh.

My experiences with bullpup designs have been pretty shaky up until now. However, this blaster performed way better than I was expecting.

There are plenty of advantages to this design other than its compact size. Luckily Drev has already posted a write-up here. It isn't the exact methodology that I used in construction but should give you a good understanding of how the design functions.

To continue the trend of ESLT/bullpup blasters, here's my ESLT Blaster. The only 3D printed part in it is the plunger rod adapter. The rate of fire is unrivaled among homemades, and the catch is terrifically sturdy. I would recommend that every one build one or buy one


My +Bow, with a thumbhole stock based off of NoM's.

And finally, my Pumpsnap 3.0. I used bits and pieces from NoM's 2.0 writeup and Naturalman7's 3.0 writeup to build it.

[Alfatrooper]

New Double Snap based off of He Who Mod's blaster. The pump is made of 1-1/2" pvc couplers. I am getting no pre compression due to slightly different dimensions.

Just a little bit of aluminum porn for your Sunday night pleasure. This one is for Shoopy (and is, of course, very late), and it includes the new stock rod reinforcements that I came up with to prevent shearing at the connection to the rear plate of the blaster. There's no plunger assembly in it yet because I'm machining the first x-profile o-ring plunger head on the CNC lathe at work tomorrow morning.
