Spent several hours today working on drilling and mounting main landing gear legs. I had some confusion on the weldment tube and the 1/4" hole that was to be drilled 3 1/2" down from the top of the weldment tube. Inside the weldment tube, at 4" down from the top of the weldment tube, is the end of another inner tube/sleeve. I could not get the leg to go inside this inner tube no matter how I tried to work it into it, so I misinterpretted this to be a "stop" for the leg to be positioned against, then mounted.
Since the leg would not go inside this inner tube/sleeve, it could not be inserted far enough inside the weldment for the hole drilled in the end of the leg (1/2" from one end of the leg) to line up with a hole that was to be drilled at 3 1/2" down from the top of the weldment tube. When the leg was inserted as far as I could get it to go and was against the end of the inner tube (which I incorrectly interpretted to be an intentional "stop" for the leg), in order to bolt through the weldment tube and go through the mounting hole in the leg, I had to drill the hole in the weldment tube 4 1/2" down from the top of the weldment tube.
Both main gear legs were mounted by inserting them into the weldments until they stopped when hitting the end of the inner tube/sleeve, and the weldments were drilled at 4 1/2" down from the top of the weldment tube, and the legs bolted in place.

The end of the inner tube that stopped the main gear leg from inserting further into the welment tube.
Hole through welment tube drilled at 4 1/2" down from the top of the tube rather than 3 1/2" down.
