Need help with mortar tube

[Juliusthegreat]

Hi, I have only found pipes that is 50 mm or 75 mm here in sweden (and we measure the outside here). What I know most people use 2" and I guess that is the measurement inside?

So will a 50 mm (2") on outside be enought?

I have also looked for tubes made of paper with no luck and metal pipe will be too heavy unless I might find a aluminium tube.

But I still need to know if it´s 2" inner or outer measurement.

Her in the States, a 2" ABS pipe is 2" on the inside of the pipe. I believe the outside measurement is 2" 3/8. Not sure what that is in MM.

Hope that helps.

It helps a bit. I now know that the size is 60 mm on outside. So I guess a 50 mm tube will be to thin.

Thanks
