Dimension and thickness of early angle iron frames

What is the general flange dimension on early automobiles that use angle iron for the frame rails? Also what is the thickness?

From experience I would say 1 1/2 angle iron 3/16 or 1/4 thick. You could go to the metal shop see if a piece of it supports your weight.

I had the thought that the frame member, built from typical angle iron would have the vert. leg longer that the orizontal leg. I agree, without any experience, 1/4" would probably be suitable.

So I just went down and measured the various parts of the frame and supports on the early gasoline carriage I am working on. Unfortunately, I can't tell you what it is, because I don't know yet. Research is continuing.
The two side rails are 2 inch by 2 inch. The front and rear cross pieces are 1 3/4 by 1 3/4. Three additional cross pieces, two are 1 1/2 by 1 1/2. the third one is 1 1/2 by 2 inch. All pieces appear to be 1/4 inch thick.
I hope this helps.
What are you working on?

Thanks for taking the time to post a picture and sharing measurements. I do appreciate any help as I begin restoration of my pile of parts.

The photo above and below are from an Ebay auction that I didn't win so I can't take measurements and give more details. A man I met through the HCCA forum (PaulSantone) and I are interested in building early cars, and would like to see pictures of other projects.
Cross members are riveted and engine supports are bolted.

Little Giant frame dimensions

For what it's worth, the frame on my 1911 Little Giant bus is made up mostly of 2 x 2 x 1/4 angle, with two angles being used per side in the middle of the frame. This chassis has a 1 ton capacity so the design won't directly apply to a passenger car.

Thanks for taking the time to send pictures of early angle iron frames and parts. If anyone else has pictures, please post. I am trying to learn and prepare myself before I start on my porject.

PS: I am also looking for an open style planetary transmission. Does anyone know of one that is available?
