Arena Assembly, Overpass ... DWG Error?

The side you turn down to 1.287 also goes into a tube that has an inner diameter of 1.334" when the Overpass is assembled.

This is meant to have a nice tight fit on one side, and a looser fit on the other.

That's the answer I was looking for ... it's a looser fit on purpose. I get it.

... and to be perfectly honest, we're not building exactly to print. We have matched the OD's, but have used smaller thickness tubing for our arena assembly. Saving money and weight and time, but still getting all of the physical dimensions that we need for our testing.

Building it. It didn't hold us up, as I found some electrical conduit stock that serves that purpose nicely. I was just wondering why the drawing only showed the reduced O.D. on half of the pipe when both ends went into the same size pipes. You cleared that up nicely. Thanks.

You got THAT right ... and Thanks Again! No discouragement here. I love this forum ... and this family ... and this experience. I wish it was around when I was in HS. (Class of 1985!)

Today I got to teach some newbies how to weld! I'm only a 2yr veteran welder myself, but I was able to lay down a couple "stack of dimes" welds to impress! I think we will take and post some pix of the less than perfect welds from some of the first-timer students that tried their hands tonight. Not everybody can be like Mikey and Paulie on OCC ... it's a lot harder than it looks!

Nice.. If you're actually building one there is a low cost field option available as well that you knew about right???

Yea ... we almost went that way, but then we figured we'd end up breaking the PVC ... so we're choosing a 3rd option ... somewhere in-between.

And we may not build the entire assembly ... for now we're focusing on getting the overpass built ... we might just mock-up some of the other assemblies.
