to .22. Just a little project I have been fiddling with a little evenings and mornings. I'll upload some pics later. Just teasing you guys right now with the thought. I just gave it a test fire, and it fires and being it is sans sights and barrel shroud at the moment I only shot it 5 feet at a coffee can in which it of course penetrated both sides. It would have been a lot easier if I just bought a .22 barrel liner, but I had 1/2 of a 24 inch Crosman barrel here, so I modded that to fit. On one of my $99 Harbor freight wood lathes with various files. pics later, time to make some money, then play with it later, then pics FYI so far a real easy conversion.

Just curious, how did you chuck the barrel up in the wood lathe? I would like to see you post some stuff about turning metal on a wood lathe with files on here too and any hints or tips you may have if it wouldn't be too much trouble. I do a lot of wood working and not enough metal work to justify buying a metal lathe. I know it can't be as precise but I am not really looking at making production stuff, just getting things close enough to finish off by hand would be a good thing for me!
On my cheap lathes of this style there isn't any chucking up. The barrels fit in the tapered spur on the drive end and on the tapered end of the live center on the other end. So the ends of the barrel, the bore holds the barrel centered. I have one more Crosman barrel that I will mod to fit another Daisy and I'll take a few pics of the barrel modding process.

What keeps it from moving if it were to get bumped? Did it fit inside the shroud ok? Is it tight enough to keep it from moving?Thanks for the info!
i like the look of that 880 shorty. who makes a current production .22 soda-straw barrel? are there any available for the 22x? or the 2200 magnum?
Cool stuff Tom...We are sort of alike and opposite...You are doing a Crosman barrel for a Daisy... (a Craisy )I am doing a Daisy barrel on a Crosman... (a Darosman )Thanks for sharing... If they had not killed it in shipping I would have had an 880 to follow your lead with.
Tom the problem with using a .22 barrel or barrel liner is not the twist rate, the problem is that .22 pellets are not actually .22 and they are to small for the liners.I thought of getting a Marlin micro groove .22 barrel to use because their rifling is most like an air rifle (shallow land and groove) but the only .22 Leads I know of that you can get are from North American Arms meant for their cap and ball pistols...http://northamericanarms.com/accessories/cb-accessories/cb-parts.html

Though the Pellet Rifles in .22 are true 0.22 inch bores, the Powder burners are closer to .225 or slightly more. This is do to the difference in the way that the projectiles are expected to engage the rifling, on a pellet rifle the air expands the skirt into the groves (ideally), where as with a PB the over sized bullet is pushed into the rifling.
