This is a necessary step for any wheel that will be "riding" on an axle. Wood hub wheels and sarvin wheels need a metal sleeve or "boxing" compression fit into the hub so that the wheel can "ride" on the axle. We offer this service for all sizes of wheels and axle widths.
Need a little extra guidance? The book Wheelwrighting: A Modern Introduction Vol II covers wheel building methods such as boring the hubs and setting the boxings plus much more!
