Stumps clone skin thickness

Post by jl170 » April 21st, 2015, 8:07 pm

Hi all

In the process of designing a Stump's clone. Frame is 50mm / 2" SHS and overall dimension of 1093mm / 43" high by 853mm / 33" wide, and cooking chamber is designed around BBQ spare part grill at 400x485mm (15.7x18.9") and about 650mm (25.6") high.

Just wondering about the skin, and what thicknesses people are using. Considering anything from 1-2mm. Hmm, that'd be 1/8 to 3/16 or thereabouts for y'all.

Hopefully this being tube and sheet and nothing fancy like a barrel in a Texas smoker comes out a little more practical for fabrication handling and cost.

thanks!

We usually do what's known as 14 gauge thickness...not sure what the measurement thickness is...


If you can't fix it by sheer force or cursing......then it can't be fixed.....

Mine is 14 but the inside wall that the crossover transfer tube terminates against is 12. Personally, I think that was too heavy but I had it. The outer skin temps measured with the heat gun rarely exceed 75 farenheit but it was winter and usually about 40-45 when I was using it. And that is 2" tube with rigid insulation

From what I see on the charts, 1mm = 19 gauge = .04" and 2mm = 14 gauge = .08". 1/8" is .125" and is 11 gauge.


If it's tourist season, how come I can't shoot 'em?

Thanks for the inputs, 2mm / 14 gauge sounds like it. Possibly will work with a thinner external depending on how much flex at the sizes we will be cutting and the weight saving.

Good move. I have some very good quality and weight supporting wheels but they cannot support the weight of my smoker as well as I'd like it. It flat spots them. I did a few things a bit differently based on one of your countrymens advice and it was a good suggestion. Like a rainwater dam on the top fill door.
