Outta curiosity,where would a fella go to get sheet copper ?

I have bought it at regular sheet metal fabricators

Small sizes can get through places like Graigers or McMaster Carr. Larger go through regular metal vendors. Making a still Wolfdog?

A sheet metal shop that does architectural metal,(metal roof ,cornice, gutters)

Here they have a small selection in Menards and I would think Home Depot. It is just small sheets though.

Google search showed my local Ace Hardware, Lowe's, and Home Depot carry the small sheets for hobby/craft work.

Amazon too.

Southern States always carries sacks of corn there buddy.
You running propane or wood fire? Wood is cheaper, but propane won't put out the smoke if you know what I'm gettin at.

Craft stores, hardware stores, etc for small sheets. Maybe 2 x 2 ft square or so. Sheetmetal suplliers or fab shops for larger stuff. Don't forget to check for roof flashing if you have a well stocked building supply place. Flashing and gutter stock may be thicker material too than the sheet stock at hobby shops. Local scrap yard might be worth a look too.

Well you know I got that ole pecan tree in the pasture that needs some burnin anyway and folks round here always burning trash in the yard

you can buy sheet copper at roofing supply companies. in different weight and sizes.
