My friend did a heavy arrival in his Rans S6, getting pushed sideways by a sudden gust which bent the right u/c leg, broke the nose wheel leg and propeller, but very little else was harmed. The engine is away for shock load testing and we've replaced the nose wheel leg. Our LAA inspector is satisfied that the airframe including the socket for the bent leg is completely unharmed.
The reason I'm asking for your advice is that it's possible for a leg to get bent and need replacing in a Europa, which has a similar leg fitting into a similar socket. I don't know whether the Europa leg comes with the hole pre-drilled for securing in the socket, but the leg for the S6 doesn't.
We've read the aircraft build instructions, which show making a simple jig with angle iron and attached pads to ensure that the axles are aligned. For me the scary bit will be trying to mark the exact centres on the side(s) of the leg for the entry and exit holes through the solid leg, to coincide exactly with the holes in the socket. The leg steel is extremely hard and cobalt drill bits are required, to be drilled at slow speed with plenty of cooling fluid, while the leg is supported in V-blocks.
Even marking the leg with a centre punch might be easier said than done, so considering that I've never attempted such a task before and how expensive the leg was, your advice is sorely needed.

Jon,
The Europa gear leg is predrilled. The mounting tube is inserted into the fuselage and rotated to align the predrilled gear leg with the angle iron epoxied to the floor at a 90 degree angle and at the proper station position
