I am not a fan of woodworkers source. Will not buy wood from them anymore due to their policy of rounding up in measurement and charging for "air". You can find smaller pieces of wood here that can be cut into pen blanks. I would take a tape measure with you and MAKE sure they dont overcharge you.
Anthony's is a good place to go to view pens. He has ALOT of different styles and is generally a nice guy to talk to. [
] Plus the drive there is very nice if you have never seen the desert in the "off summer" season.
Chandler Hardwoods was sold a little over a year ago. The new owners have raised prices but you can still find some stuff in there. They just purchased a warehouse and mill up in Oregon and are working on shipping wood here. The previous owner is "suppose" to be sending wood from somewhere (location escapes me) in the SE of USA but I have not seen any yet. It is between McQueen and Cooper on Queen Creek road. I visit it too frequently due to Parents live down the street.
Place in Mesa,Timber Woodworking Machinery, is on Southern between Mesa Dr and Stapley, south side of road. I found some real nice mesquite there but just didnt want to buy the whole board.
Hope this little review helps.
