Shipping 8.75 chuck?

I used milk crates in the past very successfully. I did put some thin plywood on the bottom and the top and nailed to plywood at the top for protection. You may have to wrap the crate in cardboard or they will charge you a $10 unboxed fee. I used zip ties to secure the case in the crate so it won't roll around and cut the crate handle openings in the cardboard to make it easy to carry. It seemed to work fine. One crate went to California and one to Oklahoma.
