I’m looking for steel pipe, not 4130. Specifically I’m looking for 10xx steel tubing supplier in California. None of my suppliers for my flat stock care or are willing to order what I need. This is for the aileron hinges, splice places and the torque tube/aileron drive for my S-4c scout project. Any help would appreciated

Thanks

Don

You want steel tube not pipe, but you probably know that. Any steel distributor can have the stuff added to their order. Race car shops would be one place to look, but even then they order. Just like you building a WW1 plane, thin tube in any form is rare. Most just get 4130. In the 60’s there may have been a cost advantage but not much anymore.

The dimensions are fractional, if they are to telescope one inside another or used as a hinge you need to buy .049 wall and weld over a solid or thick piece of steel bar or tube to minimize the distortion or you will warp it or have a long time with a file to get it to assemble. The tolerance budget for .058 wall can put you at less than 1.25 ID.

^ This. be prepared to tweak it with a hammer on your mandrel to fix any warpage. A solid mandrel is highly recommended. You might get away with 058 and a hammer. 4130 is an upgrade and far easier to find than seamless 10**.

Sorry I was using pipe vs tube. They used MSP not 4130 in WW1. Outside diameter is critical the inside can be adjusted to fit on a lathe. I hadn’t thought about custom car shops. I’m trying to avoid mixing the metals. The plates that weld to the tubes are 22 gauge so welding will be fun. I plan on using a jig to help keep thing aligned and to help control warping.

I’m really being forced to learn on the go. At least I can make as many attempts as I’d like as I’m cutting the plate stock on a Cnc plasma cutter .
