Tail skid fitting
The steel is pretty thick stuff - .100 steel - guess they wanted the tailskid to be strong. Anyway, the only way to bend metal of this thickness is to heat it with a torch. I bent it over a spare piece of 1 in. tubing (same as the skid tube) using a lot of heat and a bit of persuasion (hammer).
After transfering the paper pattern to the steel, I couldn't cut it in the bandsaw any more. The bend took care of that. So, I reverted back a tried and true method - the hacksaw! It worked perfectly.
The grinder took care of the rest.
Here is the piece after grinding.
