Post The Larpquebus ( LARP 'Nerf' musket )  Reply with quote
Work is still ongoing on my little LARP musket project that I've previously posted about, and I'd like to share some of my recent work.

This is the pre-production prototype sitting in its unfinished stock, this model is tuned to 95FPS to ensure it is under the 1J muzzle energy limit.



The internals have been 3D Laser printed in nylon, the catches are laser cut in stainless steel.



The layout of the internals. There is nothing very special here, just my take on the regular rainbow catch and springer air piston. The large white nylon section holds the internal barrel, as well as the safety catch for the ram rod. The main catch itself can be seen on the right near the screwdriver, the return spring is fitted in a recess inside the catch, rather than outside the barrel on the pin, as I find it gives a smoother action.



And the "matchlock" mechanism. This again is laser cut in stainless steel as regular steel rapidly rusts due to the corrosive nature of toy caps (we learnt this the hard way)



The lock plates are also laser cut, as it's less trouble than cutting and drilling them by hand. Plus I can get decorative touches added very easily.



Machining the pseudo-barrel / air chamber




Mind you at this point, I feel I'm beginning to stretch the definition of 'homemade' a little. Wink

That's brilliant mate. Something I'd never of considered doing myself but I can appreciate it all the same. Marvellous (what? I'm bringing it back.)

Glad this is becoming a thing..... not long now and we can make a game specifically for them.

Make one that shoots 120fps and I would be tempted!
The quality of the parts is superb though. Very impressed with the machining too.

Thank you.

The one in the picture has been chrono'd at 153 > 160FPS, but subsequently retuned to 95FPS.
Bear in mind this fires Rival balls, not darts (as the balls are more akin to Arquebus & musket shot)

I know that higher velocities than 160 are possible. There is a mechanism in the barrel, which can retain the ramrod in the gun if it's left in and fired. However that same mechanism leaks air when it's fired, plug that leak and you'll get a bit more power (fixing/reducing the leak is on my list of improvements)

If you do, let me know, and I'll see what can be done to support it. I'm currently chatting to LARP traders about them stocking this gun.

Fingers crossed, it's been on the to do list since the start of the year with "The Drop" Nerf-larp plans ahead of it, but the rules for the drop are now pretty much completed and looking at locations for next year so once that's done I'm eager for a low fantasy mercenary system to follow, the main difference with what I want to make is putting a silicon valve of the sort you get in sauce bottles over the plunger tube so I can put powder in the barrel without it getting into the gubbins.

*edit
and I'd not put anything like a safety against the ram rod being fired.... but have since added that to the must do notes

I've tried the silicone valve*. I found it was not very effective as it reduced the FPS by quite a bit, and the ramrod wrecked it fairly quickly.

In the end I found simply putting the powder in after the ball to be much more effective. Wink


(* actually I tried a nitrile valve to be honestly fair.)

If you don't mind me asking, what is the expected price of one of these?
On the subject of ramrod safety, might I suggest a "retained ramrod" as seen on the 1796 pattern Dragoon pistol and Paget/Nock cavalry carbines of the same era. This would add 4 parts but fully prevents the ramrod being fired, at least by airwith a foam ball.  When black powder shooting it's still possible to rip the ramrod mount off the barrel!

The final price will be determined by the Traders, as I'm generally not going to be selling direct.
However the prototypes have been sold for £150, and I'm expecting the final price to be somewhere around that.

I've seen that retained ramrod thing, but not studied it. It might be worth considering. Thank you.

That's a good price for the quality of work. The retained ramrod is nice and simple, it is just a collar that pivots up from the level of the ramrod hoops at the muzzle end, the ramrod slides through it.

Yeah, I'm thinking that might be worth putting on the later period muskets, maybe as an option, as something that complex would increase the price. Though by how much I don't know.

Hopefully I'll have a pistol version to present here at some point in the next couple of months as well.

I would definitely buy a pistol version. Buzzbee pirate blaster sucks. Two bits of metal and a pivot for the ramrod is not much extra cost, just add to the bits for the lock on the laser cutter or have a small batch etched in brass. Loads of places do small runs of brass for railway modellers, in a variety of thicknesses.

This is some truly stunning work and i might just have to indulge when the production run starts, however you've set me to wondering if one could smith a blaster with a martini style action, as that's where my personal interests lie? Could we not even stop there and totally revolutionise the reenactment industry with dart/HIR firing masterpieces? Wow, what a concept you've created.

Yeah. Though I'd be really tempted to use Co2 on a Martini-Henry style blaster. Not that I've given it any thought or anything... Wink (or researched and priced up the regulator required :p )
Nor can I confirm or deny I have a prototype  Co2 Nerf rival pistol in my workshop...

(Note the 17thC pistol is NOT Co2...)

Hi.

Anyone interested in seeing the Larpquebus in action, I'll be demo'ing it at Larpcon, Saturday March 4th at the Hermitage Leisure Centre, in Whitwick. Leicestershire.
