Bought a used tripod for 40 bucks. Thinking of somehow using it as  a mast for my wellbrook loop antenna. Any ideas?

Go for it!  I've got a tripod of sorts I purchased from a disc jockey when he was selling off his equipment.  It was made to hold a heavy light bar about ten feet in the air, so it has no problem holding a higher frequency antenna.  The only problem I have when I do use it is people tend to trip over its legs.  The only thing I would say is use some method of staking its perimeter--at least the legs--so it will stay tall and won't be knocked over!

If you hang a heavy weight from the apex of the tripod so the weight is close to the ground you will lower the centre of gravity making it less likely for it to be blown or knocked over.

I wasn't clear about the staking I mentioned.  What I meant was to put some sort of perimeter staking around the tripod base so people would avoid it.  Yes, you could tie the tripod legs to the stakes, but hanging a weight does the same thing, it stabilizes the tripod.

  Cut out a circle 6- 8 in. diameter from high density plastic cutting board or 3/8 in. plywood,attach appropriate pipe base flange on top center with sized bolt going down through center and hole in top of tripod transit base plate and secure with large washer and nut.Short conduit pipe mast from flange to bottom loop mount.As above properly secure legs.
