UPDATE: I went home at lunch and drilled another hole in the mast base, then raised the mast all by my onesey. It worked great with no need to pull down or back on the mast.
I used the stock pin in the bottom and a small phillips screwdriver in the top hole. Tonight I'm going to weld two pins to a ring for a two-pinned key that I will attach with a string or cable. The only drawback is that you have to lift the mast to a horizontal position to get the holes to align so another person would be helpful. Today I used a ladder. Some sort of pole support may work and I'll come up with something for when I'm solo.
Attached is a picture of the second hole in the mast base.
