Hi Larry

I bought mine at a shop that sells bearings, connectors, collars -
industrial goods place.  

I have an extra rotor shelf in my 25G that helps keep the mast from
tilting if one has to take the rotor out.  I leave a split collar on the
mast and simply loosen & slide it down on the spare rotor shelf when I
have the mast hoisted for removing the rotor.

These aren't expensive and they hold.  My mast is 2 1/2" OD, is 21'
long,  and I can't lift it.  I wouldn't trust hose clamps - maybe not
even muffler clamps. 

Split collars work good.
