[Shop-talk] Bear proof bird feeder.

[Peter J. Thomas]

I have a bird feeder on a post made out of galvanized iron pipe. Bear 
keeps bending it to the ground and I keep bending it back. Tired of this 
routine so I plan on making a bear/squirrel proof bird feeder.  I 
ordered a 7.5'x3" aluminized steel 16 gauge exhaust pipe (required shop 
content for this post).  I'll dig down about a foot to bedrock.  Cement 
the pipe to the bedrock and fill the pipe with cement, kinda like a 
lolly column.  I'm pretty sure this will be strong enough to resist the 
bear, unless he brings his brother, and thick enough that the squirrels 
can't climb it.

On top of this I plan to make and weld a bid feeder but not sure what 
thickness of steel to used.  Once complete I'll paint paint auto paint.  
Any insights?  Thanx
