Thickness of stainless arch sides

[claystroup]

Does anyone know what the thickness is of the stainless steel sheet that is commonly used on arch sides.

Thin enough so that is is easy to work with and thick enough to support your brick. I was fortunate so salvage the stainless for my arch build but it was on the thick side (around 10 ga) and a pain to bolt onto the arch frame. I never used so many drill bits on one project in my life.

I think most are 20 ga SS. To drill SS use a cobalt bit, it works best for SS. You should get several holes, if not all of them on one bit.

I talked with leader via email and they told me ( all 2' wide arches get 22 gauge anything bigger get 20 gauge ) . And yes , cobalt drills work best . Starting with a smaller pilot hole first makes them stay sharp longer . And having a ( drill doctor ) is real handy to have .
