This is basic info that I just don't know.
What are the weights of the following:
1" square 18 gauge tubing per'
3/4 round 18 gauge tubing per'
16 gauge sheet per Sq'

I'm making a 1/4 scale model of a chassis and I'm worried that if I keep adding diagonals it's going to need a diesel truck engine to get it rolling.

Thanks

try , this does the calcuations for you depending on gaug and size.

Sounds like an interesting project, is it to develop skills (welding etc?) or just for fun? Was thinking of something similar myself to teach myself to weld. What will you be using as wheels?

FYI

As thats how we buy it:

1) 8 swg = 4.06 mm
2) 10 swg = 3.25 mm
3) 12 swg = 2.64 mm
4) 14 swg = 2.03 mm
5) 16 swg = 1.63 mm
6) 18 swg = 1.22 mm
7) 20 swg = 0.914mm
8) 22 swg = 0.711mm
9) 24 swg = 0.558mm
10)26 swg = 0.46 mm

I have a spreadsheet with mass per metre for all 1.6 and 2 mm wall hollow section (12.7 mm to 50.8 mm) and round tube (dia 15.88 to 42.66) and 1.6 mm wall ëxhaust tube" (38.1 to - 50.8)

E mail me if you want it.
