I have no background in engineering, but I'm fairly sure you must have to make what you have there. It looks functional, individual, has a character all its own and obviously shoots well. I'd love to have the skills you've got to make (or even understand) the workings of air guns well enough to do that. Congratulations on a brilliant job.
I wish I had the tools to build my own hammer valve and stuff :( your airguns are awesome I like how you mill out all your valve mechanism and your receiver and everything. Cool work man.
Thanks! The airtube in this clip is a ready made tube.. taken from an old FX airgun. If you decide to build your own tube i would recommend using a non ferrous material, aluminium or maybe titanium. A safety factor of three is good for peace of mind... If you plan on using 200Bar fill pressure the tube should be built to withstandan at least 600bar pressure. A 32mm outer diam pipe, 5mm wall thickness in 7075 should work fine. good luck with your project!
@s10m0t10n Thank you for the kind words! I work as a physio, specialized in manual theraphy... no engineering background whatsoever.., and two years ago i hadn't even seen a PCP-gun in real life... It might sound strange but thats the truth! Ever since I was a kid I've been obsessed with building my own "toys". Whenever i see something that interests me i start thinking of how to build one myself. Sometimes it would be nice not having this obsession... cheers
@Australiaroo I have a rather unusual three axis bench lathe... Headstock can be elevated approx 150mm. Very useful for milling operations. I don't use a moderator for two reasons; first I shoot at low power so the gun doesn't make that much noise, and second, in order to own a moderator i would need to apply for a certificate... Good luck with your project, and don't forget to show some pics!
@Australiaroo The size needed depends on how you intend to do your machining... Look for a lathe with a crossfeed same as length of receiver block or more.. makes milling easier. Make sure spindelbore is big enough for your barrel. Length between centers; you dont need that much but go for receiver block lenght x2 + an extra inch. An old south bend 9" lathe would be perfect for a job like this... Avoid the really chep imports.. Cheers
Thanks Ray! I didn't do any proper drawings for this one.. I do think i did post some build pics on my friend Pedros website; "airgundevelopment". If you haven't built any pcp guns before i really recommend that you try to get hold of one of Mr HM Buckley's books, it will make it a lot easier! best regards
@Loomis26669 Thanks! Sinces this vid was shot I have fitted a 600cc airbottle to this gun, also incorporated a adaptor to accept a standard FX fill probe, so no need to unscrew the bottle for filling. Also made a new adjustable buttpad to replace the one in the vid. The airtube from this gun has ended up on my bullpup, and the bottle from the bullpup is now fitted to one of my other guns... I like to make parts interchangeable! regards
Thanks for your comment! I have learnt everything i know about PCP-guns from reading Mr HM Buckley's books... As long as you understand the basics of how a pcp gun works it's just a matter of performing some basic machining operations... cheers
@Australiaroo Have you checked with JDS Airman? Pressure vessels are pricey... but on the other hand they last a looong time. Bottles are sold new for approx 65-90£ in the UK... buying second hand might be an option for you. People tend to swap for bigger bottles every now and then. don't give up!
First rate rifle, and very nice design, are there any videos of the build? and are there any drawings available for purchase I would love to attempt a build, I have recently retired and I am looking for a good project. Keep up the good work you are an inspiration to us all. Thanks Ray
I'm a "build your own toys" guy myself whenever possible so I can afford them. Being able to fix things is kind of a curse as I tend to collect broken stuff I know I can fix but it just sits. Good job on learning how to build these air rifles and also on your command of English which is a lot better than my Swedish! Would you consider selling a receiver (with the revolving cylinder) set for .22 cal? I could build the rest and you get more tools! 8-) win/win?
I took the barrel from an old FX airgun.. just removed the brass piece with the transfer port that FX had fitted.. then turned the shank to the right diameter. I'm not sure what you mean by "chambering"...; are you referring to the small taper at the breech end? I normally cut that with a small special grind HSS lathe bit.., like a miniature boring bar. Then polish with abrasive paper. Easily done on this gun since it has no transfer port through the barrel. thanks
@tinkerrbill According to my brother i suffer from "Hexagonalis" aka "nuts and bolts disease"..., very closely related to "the repairman's curse".. The knowledge that everything can be repaired can be... painful. Anyway, thanks for the kind words. As long as you have acess to a lathe i'm pretty sure that you could pull of a project like this by yourself. My problem is the constant lack of spare time... but.., drop me a PM regarding what you want to buy. thanks
Thanks for your comment! In this vid the gun is fitted with a Lothar Walther barrel, 500mm in length. Barrels are available from Chambers gunsmiths in UK, have a look at their website for prices. thanks
Thanks guys! One of these day i hope to get enough time to make a "real" stock for this one.. I have been thinking of something along the lines of a daystate MK4 stock. Aside from looking a bit ugly, the ergonomics of this stock is actually pretty good.. so i might stick with it. @togaida - i bought the barrel and airtube as spares from a fellow airgun enthusiast. Cheers
Ah, I was thinking about using a l.W barrel, but quite expensive (more than 100£)... Did you blue it? And how did you do the chambering? Because these barrels doesn´t come ready to use... Thanks for anwer
Hi I like your videos, your rifles are awesome! Do you also build your own air tubes, if so, what are the required materials and specifications? I live in south africa an I would like to take on a project like this. Thanx.
@sasquatch200269 well... there are actually no plans for this specific gun, but it is very much based on Mr HM Buckleys designs. I just added a sidelever.. Have a look at airgundevelopment(dot)com for info regarding Mr Buckleys airgun building books. cheers
How do you make a pcp-gun without an engineering background? I don't believe you. Maybe you excelled in Physics or Technical drawing when in secondary school, or maybe you did engineering in the armed forces, or maybe you have worked in an engineering plant/factory, or maybe you have friends or relatives that are engineers or have these experiences.
