That is gona take some lengthy sheet of paper to make a good strong tube at only 80 or 70gsm. I personally find it easier to use lining paper, or my new addition floor lining paper or just A4 card at 165gsm or 250gsm. This stuff makes very strong tubes that can be re-used constantly.
I just like kraft paper for pasting shells, If I'm making tubes I will use heavy duty like you and finish it off with kraft, or even news print to keep the edge down. I just thought it was a bargain and needed to share it with my fellow pyro's

Inoxia sells 70 g/m2, but is that the same as 70 lb?
I am not sure of that vic,over here it is all quoted in g'sm,but all the american literature is in lbs,as in 30lb craft etc,but i dare say somebody knows the conversion

To convert from basis weight in pounds the following formula may be applied equally to basis ream weights of any dimension, e.g. 17" x 22", 25" x 38", 24" x 36".
Multiply the basis weight by 1406.13 and divide by the square inches in the base sheet.
For example:
To convert from 20 lb. 17" x 22"/500:
20 lbs. x 1406.13 ÿ 374 = 75 g/m2
To convert from 50 lb. 25" x 38"/500:
50 lbs. x 1406.13 ÿ 950 = 74 g/m2
To convert from g/m2 to pounds the procedure is reversed:
Multiply the g/m2 by the square inches in the base sheet and divide by 1406.13.
