    Dear Friends.

    I need barrels to my 1/4 big gun cannon.

    Where can I buy barrels with ID 1/4 inch?

    thanks for all

    Check McMaster Carr for thick wall stainless tube.

    3/8" steel brake line works. If you want higher performance, consider adding a sleeve with a smaller diameter to reduce the blow-by. Remember that you need a certain amount of slop to account for the squishing and deforming of the material when you bend it.
