Rifling small bore barrels

[rna_duelers]

I have just rifled my 3/4" barrel on my pneumatic using a piece of dowel that was a good fit and having hammerd nails into it and gridning them back to just points that etched the bore of my barrel and i spun it as i was pulling it and it worked really well with a carrot slug it spirreld through the air nicely and didnt tumble until it reached the end of it flight parth.
Ill have pics soon in about and hour or so.

EDIT: i need somewhere to reduce the size of my photo's,any help would be great thanks.im not 2 good with computers...sorry

Ohhk and yes i did do it by hand and i live in australia,not missisipi(spelling:S).Well it is very consistent and i did it extremely slow as to get it perfect and also becuase it takes alot of strenght,its quite hard to pull through you know.I out my pipe in a vice with the bushing acting as a stopper so it wouldnt pull through and scrape my barrel,i thought it would of been really hard to do but surpirisingly it was easer then first throught.

Now with the dowel i used 4 nails they where 20mm small tacking nails.and i set them as to cross through the dowel on four different points as to make a + through the dowel and only have about 1-2mm of nailhead showing this is why you use a tight fitting dowel,and i off set each nail about 15mm from each other along the dowel length wize as not to crack the dowel and so the nails dont hit each other but trying to get the nails to go in straight,that was a fun i can tell you.then it was up to my trusty dremel grinder to grind back the protruding end of the nail(not the head).Now first thing to do is to test it on a small section of same size pipe as not to ruin your good barrel and test it,you may need to do some fine tuneing to the nails head with a dremmel to set the depth not to deep and also to make it easer to pull through

BUT WAIT!!!joel said it was impossible to rifle small barrels,otherwize he would have them for sale...well hehehe i made my own:P and it works,i will get some more pics of the proccess and post soon,but im school holidays so i might not post right away because i have alot of things to do(drink cola,watch tv,sleep etc etc)

To reduce size of your pictures, go the paint and then go to Image: stretch and skew. Do horizontal and vertical in = percentages and there you go. I like that idea, I thought about tryo to rifle by somehow mount sharp tips slightly larger than the ID of the pipe on a dowel and then hook the dowl toa drill. Like the bore in the how-to section.

This is something everybody wants to learn so get them darn pics up haha

if u had a dowel for 3/4" cpvc would rifling a pb barrel have affect on the paintball dumb question but the shells are hard so idn if it would do anything

[boilingleadbath]

A paintball is a sphere anyways - riffling has no effect on the tratractory of a sphere, even if it did work at spinning it, which I doubt.

(Ok, slightly wrong. But having it slide over to one side (slightly) as it falls is a bad thing anyway. And I do mean slightly... although I'm not going to calculate it, I don't think you'd notice it)

Ohh and sorry!i totoaly forgot about this post and thank you screamingflea now i can post pics!becuase before they where much to big.if u have any question on it just ask.

[boilingleadbath]

The twist rate is surprisingly consistent... surely you didn't do that compleatly by hand.
Could we get a description/pictures of your setup?

[plumpthumb]

Hate to disagree about rifling having no effect on a sphere but if you will stop and remember the muzzle loading was made far more accurate and given longer distance with the invention of rifling-those weapons used balls. That's why they are called rifles.

[screamingflea]

Glad to help, anywho, the I have to agree with BLB, the twist rate is suprisingly consistint, I might have to give this a try. A carrot slugger sound like fun.

Holy Sh*t!

Either you got the steadiest hand on this side of the Mississippi, or you didnt use your hand... Sorry for the third echo, but how did you do this??? (This post doesnt state anything new, only for adding to the urgentness.)

[sam_516]

Ahhhhhh that is mad!how did you do it so steadily?????i thik im gunna rifle my 1/2inch barrel now.

[Brian the brain]

Wait a cotton-pickin' minute!! You could twist tape around the dowel in a steady spiral and tape a marking in the end of your barrel and just follow the spiral...as a guide!!!( or cut out the spiral and use a screw as the guide!!)

mmm

[rna_duelers]

Now thats an idea,i'll do that next time thanks brain.

the muzzle loaders actually didnt use spheres... those were muskets, my friends dad has a muzzleloader that is rifeled, and i have one of the bullets, it looks like a very stubby .50 cal round which in fact it is
