Take two pieces of 1 1/2" angle iron about 8" long and bolt two sides togeter, you now have a T with a 3" side (1.5 + 1.5) and the leg of the tee is 1.5". Drill across the 3" face for two, 2" ubolts. Drill one hole in the 1.5" leg big enough to hold the pin of an anchor shackle. Attach this to your mast about 8" from the end that goes into your rotor. The shackle now makes a great place to attach your come-alone to raise or lower your mast regardless how heavy it gets. I always mount a drop forged eye bolt through the flat top section pointing down inside the tower. Attach a good pully there and run the come-along cable through the pully so the come-along can be right next to the rotor so you can guide the mast in when lowering.

Somebody (maybe K4ZA?) came up with the idea of using a basketball hoop 
attached to the top end of a gin pole to make this a relatively safe and 
secure activity.
