  • Where to get 2.5" .065" wall 4130 tube?

    Like the title says. I have been searching for awhile now and can't find any place that list it. Closest I found was onlinemetals with 2.5" .083" wall. Need only a smaller amount at first so places that only sell huge amounts won't work for me.

          This place may have the wall thickness your looking for. They don't have a web site but you can look up the phone number.

              Chances are

              My stainless handbook indicates that you want a NON-STANDARD size.

              0.065 is standard thickness for 2.0" stainless tubing.

              0.083 is standard for 2.5" stainless tubing.

              Choices are:

              1. machine down the thickness on a standard size

              2. make a special order of 20,000 long tons from the Chinese manufacturer

                maybe, but doubt it for reasons already posted, small quantity and uncommon sizes are tough (its the wall thickness range for bicycle tube but way big for that re:OD)

                  What kind of bike uses .065 wall 4130? Even older bmx frames, which were deliberately overbuilt and tipped the scales at over 6-7 pounds (for a 20" frame) generally used .049 wall tube at the max for top and downtubes.

                  1" ID seat tubes have traditionally been 1.125 x .058 because it yields 1.009 ID, which tends to fit with minimal reaming post-weld.

                  Hell, the electric bicycle I built recently used .058 1.5" OD top and downtubes (it was the cheapest tube on A/S) and it stays solid feeling even when it's pushing 85 mph at WOT. It's ridiculously heavy, although it does have a ~22" long rear end to fit the massive electric motor between the seat tube and rear wheel...

                    I was attempting to point out an item (bicycle) that uses thin wall tubing and the suppliers of which could be a possible source for the OP but that the OD was likely well outside the range those suppliers MAY produce...and that the tubing the OP is looking for falls outside what common tubing sizes, OD/ID/wall, are available [too thin for most typical applications of another common source, roll cages]

                    point was sort of moot since I would guess the bulk of bicycle tubing is butted in such a manner that any piece near in size to .065 wall would be too short for his use

                      I've bought alot of specialty bends and tubing from Woolf Aircraft. They have 2.5" x 0.065" wall in mild steel on their website below, but not 4103.

                      I've found that they stock a lot more than what is on their website, I've called them in the past to find out exactly what they have.

                      I've never used Aircraft Spruce, but my dad purchased lots of stuff from them in the past for his Taylorcraft and Aeronca.
