Yes the crosman barrels are 7/16, the mrod, the 760, 761xl, the 22xx series and such. Is there anyone reading this that has a .22sg daisy that can measure the outside diameter of the straw barrel?I don't think it is 7/16, that's pretty large to put inside the shroud of the daisy line. The maintenance man where I work is planning on building an arrow gun on an old paintball gun he has, that he no longer uses. He is using steel brake line as the straw barrel. We are just swamped at work and don't have time to tinker with it at the moment.
A parting line?
That's what I thought you meant, the one he has , he got from an anutparts store, and is seamless steel tubing. It's sold in different lengths, and is straight, from the factory, like buying brass tubing from the hobby store. It's stiff, and a length of 18 inches is very rigid.
Just a thunk, but as the pressure goes up, you may have to glue the head socket in better, possibly up to and including drilling a cross pin through the shaft and threaded socket to retain it.Possibly not, but it's a thought..Thank you for pursuing this, An AFFORDABLE air bow, I have seen a video using co2 on one also..I am interested in seeing how fast a stock one will do..
the plans he demonstrated are quite simple in another video and atleast 2 people have posted their rendition of his design... he simply used the piston as an air block and a ball valve to fill for each shot.. Because it is a dump valve it may handle higher pressure well,but the compression tube and attachment would blow apart on pcp pressure..A regged 1000psi bottle would do fine, assuming the reg never fails.(same asa attachment he used for the 20oz tank
