Re: wheels
Traditionally, Woburn has used sheets of birch plywood (12 mm thick per sheet) and laminated them together into squares. The centre bores are drilled, and rough circles are scribed and cut out. They are then lathed to the appropriate diameter (between 6 and 8", depending on the year) and thickness (usually about 1.5"). Six lightening holes are drilled with a large Forstner bit, and the wheels are painted to resemble metal (just for the hell of it...). Depending on the year, some sort of conveyor belting is often attached for tread, but the pattern varies, depending on what's needed and what's available.
