steel roller

Post by Dave Smith » Sat Mar 12, 2016 5:17 pm

It is getting to be that time of season. My steel roller that is suposed to be filles with
water leaks like a sieve. How many bags of cement would it take to fill it? It 24 inches in diamiter and 48 inches wide. Maybe it would be cheaper to just buy a new one.

Volume of cylinder is Pie Are Square times Height, so 12 squared is 144 x 48 is 6912 cubic inches, divided by 1728 (cubic inches in a cubic foot) gives us 4 cubic feet. At roughly 1/3 of a cubic foot per 40 pound bag, that would take 12-13 bags of Sakrete.
What do you mean I can't do that?

Thanks Fawteen,
When I was a kid I was a wizz bang at those formulas. Now that I am a old fart, I can't remember them.
Looks like it would be cheaper to buy a new roller. Then I will have some steel for other projects.

Oops, I screwed up, forgot to multiply by cake. So 144 x 3.14 x 144= 21704, divided by 1728=12.6 cubic feet, @ .33 per bag = 38 bags.

Yup, definitely cheaper to go new. Not nearly as heavy tho.
