measuring the size of paintballs and wehat pipe to get???

[pb_gunz]

hey... to end this quickly I SUCK AT MATHS and i need some help finding out the size in cm (easiest) on a pb (the closest possible size in cm)

THANKS

Paintballs are measured in milimeters anyway so i really hoping you know how to convert mm into cm.

[saladtossser]

aren't paintballs measured in calibers? the most common being .68 ? anyways 3/4" CPVC pipe will fit it very very well

3/4" SCH 40 pvc is a crappy fit. 3/4" SCH 80 pvc is better, and 3/4" SCH 80 cpvc is even better than that.

If you really want a good fit, you need 3/4" SCH 120 PVC pipe; good luck finding it though

Or 1/2" SDR 13.5.

sdr 13.5 ????????

[noname]

Yep. Fits perfectly, uses regular PVC fittings so you don't need adapters from CPVC to PVC and it's $1.50 for 10 feet.

$1.50????????Thats cheap. Is it thinwall?

[noname]

Yeah it's thin wall 1/2" but it's still rated to 200 psi (bullshit detected). You can easily sleeve it in SCH 80 1" though.

i know of two main sizes we use in NZ, .68cal which is 17mm and you cant get 17mm pipe so you have to get pressure rated 20mm pipe the second option is using 6mm PBs the size of normal BBs and you can either use 5mm copper pipe or a bigger bore pipe and use a sabot and make your gun shotgun style.im taking that you live in a metric country as you asked for cm/mm not inches and i know in metric countries its hard to get/find SDR pipe so you might have to rule out using 1/2" SDR13.5
