Mast making Pt 4: Getting the Mast to Turn (Controllably) while working on it.

I've tried a lot of ways of anchoring the mast, and generally speaking, if you're not too worried about turning it while you're working (this is almost a must when sanding,) I found that l-clamps work the best.  During the sanding process, I attempted to screw it into the saw horses.  This was somewhat difficult as getting it screwed into the center point of the mast was difficult, and depending on which way you turn, the screws will generally want to either want to tighten or come loose.  That being said, it worked alright.

Here's the process I used:

1. Center the sawhorses, and make a lateral line on them.
2. Measure up a certain amount from the floor.  Where this line crosses the lateral line, drill a hole.  Make sure the hole is level.
3. Drill a level hole through the centers of the mast.
4. Screw through the sawhorses into the center hole of the masts.

This is really pretty simple, though I could have improved it by using bolts and washers (to allow the bolts and mast to turn together,) and by bracing the horses with sandbags to keep them steady.

Update: This failed.  Badly.  The screws came loose or snapped altogether.  Considered bolts, but this would have meant boring fairly large holes into the ends of the mast.  Figured out a fairly simple solution here.
