Why can you not use the same poles you were telling me about for spears from Lowe's?
Those are round, which works for polearms with round sockets, but not square/octagonal ones like this:
If you do something which, if you're like me, thought you would never do in reality - use the pythagorean theorem (a^2 + b^2 = c^2) - you can figure out what the round pole can be shaved down into as a square. It's much less than 1 1/4", so the 1 1/2" poles won't work even shaved down.
The round poles do work great, however, for spears and as banner poles - just not squared / rectangular / octagonal polearms.
