Brass Tubing

Instead of brass, you can use stainless steel syringe tubing. You can buy the stuff by the foot at Small Parts, and most sizes are fairly cheap, since 36" of any size will last you a lifetime. Use a Dremmel and a cutoff wheel to cut it to size: http://www.smallparts.com/products/descriptions/htx.cfm

As to the sizes, here is a very detailed chart for all scales and calibers, it also references the actual part #s at Small Parts: http://www.docstoc.com/docs/11038233/Scale-Gun-Barrel-Chart/

If you still want to use brass, one of the best-stocked places I have used with a good price is hobbylinc: http://hobbylinc.com/prods/rda.htm

Heh Joe,

Where are you going with that gun in your hand? ~ Jimmy Hendrix

jk jk jk Try hypodermic needles. Ones at drug stores come in various sizes and lengths, better yet are ones used by veterinarians. I stopped in and after explaining they were for hobbies they sold me a dozen for 1.60$! Being stainless steel you won't need to paint them, or if you do the terrible 'brass chip' will not happen. I color mine with a lighter, heat will anneal the metal for a cool darker look.

Shown above is a 1/48 scale .50 BMG barrel.

When I asked about this for my 1/24 190 cannon barrels at my LHS , it was pointed out to me to watch for barrel thickness ,or tubing wall thickness ,this may be RC but still relevant.For this scale I will use two tubes ,one inside the other ,soldered and finished on the end for suitable wall thickness.

Thank you all very much. Your info has proven very beneficial and helpful.
