bought a wood stove, one of those classic looking rectangular models on 4 legs, takes 19" logs.

I'm going to put it in my workshop but space is tight, and I also have attic space so I just can't go straight up thru the roof. I'm going to need to go out a side wall
pricing is all over the place for stove pipe. I can get a 90 degree galvanized bend for $22 or I can spend some serious money.

Anything I need to know before I go with the basics?

have you paid your dues, can you moan the blues, can you bend them guitar strings
