I have attached a couple pictures of a part I'm trying to check. The first is the print. The second is the tube I'm checking from directly above it. From what I can tell, if I lift the tube up from the opposite end 139 degrees, the two radii (one at top, the one at the bottom) will match up and fit around another 76.2mm tube (it fits fairly well). I have no idea how to get the 916.9 measurement accurately. It looks like it is taken from an intersection point at one end to the intersection point of the side I'm having trouble with. Is this second intersection point the intersection of the center of the tube itself with the cylinder created using the two radii? I have been unable to recreate such a cylinder since the radii appear so different. Any suggestions would be greatly appreciated.
I would butt up a tube that is 76.2mm in diameter if you have one. (We used to keep small pieces of extra tubing for this exact reason.) Measure a cylinder and then the other end you could simply do a point or even looks like a plane on each flat and a constructed line in the middle. Measure from the line to the cylinder and it'll give you your 916.9mm.
Sorry for late reply. Hope you got it by now but in case not or someone else is having the same issue.
3in tube is very common, Could run to the local parts store to get a piece to use to butt up to the part. I always used clamps to hold it together, but could use clay and i've had success with super glue on smaller parts.
