Post The Starfalcon Mk.1 - A Bolt Action Homemade (Design)  Reply with quote
Hello
So as you probably know by the title this is a post to show off the designs for a new homemade that I am planning to make.

I was browsing various homemade blasters and was thinking about a cool Lee Enfield Style Bolt Action Sniper as a cool plinking/show blaster more than a war practical balster when after browsing youtube for a while I began to sketch. This is the image I had in my head: http://az321826.vo.msecnd.net/629.../Products8059-1200x800-199654.jpg

It seemed really hard to create something that was dead easy to make so after a while as you can imagine the idea became more complicated. (And my paper looked a bit of a mess) so I hopped onto Microsoft Visio and created this:



I would appriciate any ideas or improvements so feel free to take the image and draw improvements on. (to post back her please)

In the image there is some text describing the materials that I plan to use. In case it is not too clear on the PNG image here is is: "The stock area will be made from 2 pieces of wood that will be sanded and cut to shape then varnished for a smooth finish. The plunger tube and outer barrel will be steel tubing and the main barrel will be PVC tube. The trigger, catch and connections will be custom made polycarbonate."

Thank you for your time if you have read this far  Surprised  Very Happy

Mechanically a spring and plunger is very hard to prime with a single bolt. The buzzbee bolt action regularly breaks off, even on its toy level spring.
The most successful bolt actions are air powered. I would skip the mechanical parts and put an air tank in the stock, then concentrate on the bolt action for loading.

Yeah I can see what you mean but I'm planning to use a metal outer barrel to try and avoid the breaking problem. As I said this blaster will only really be a show piece/plinker so im not intending to put a giant spring load inside. (I do want it to still be functional though)
Thanks for the suggestion though I've never really tinkered with air powered guns (other than a super soaker once) and I can see how it would work. The only problem might be finding an air tank with the right dimentions. Any suggestions?

You are thinking backwards. Find the air tank then design the shell. They are not complex. I like the AT3k as it has a simple trigger and good sized tank. HPA is a bit more complicated. The downside is availability. The easiest way is to get an American to ship you a stripped down XBZ.

okay, so easiest to look for a balster with an air tank and take the whole assembly out of it? What about a water gun though, you mentioned an air tek 3000 but surely a supersoaker will so a similar thing? let me know if im wrong though. I'm just thinking about availibility.

Get an Xtreme Blastzooka from the states, use the whole air tank and valve assembly. Water blasters work very differently, the good ones use a magstrike type bladder (constant pressure sysystem style) and they are not usually worth using for darts. Water and air have very different compressability.
Go look at some air blaster mods, there are tons on the web. Look at Franticblue on here too, he was good at low tech air blasters.

If you do decide to implement a non air blaster, other than what Old Noob said (and he's not wrong) you'll also need to look at your catch a bit more closely.

First, I notice that one side of the piston catch is longer than the other. Remember your piston can rotate, so the eccentric side will not always be facing downwards to face your sear (the trigger part of the catch) make the piston catch equal all the way round (tip: I use an M8 bolt screwed into the piston rod as a catch in my own blasters)

The pull on the trigger is going to be really heavy. As you'll have to compress the main spring slightly to fire. At best this will be uncomfortable to fire, at worse one of the pivots will break under the strain.
I strongly recommend looking at how the bolt action airsoft sniper trigger groups are designed, as they have to solve this same problem.

If you want a catch that is very simple, reliable and easy to make, then look up the Rainbow catch instead.
