A pinwheel structure for transporting bowling pins from a lane upwardly to an appropriate in-feed station of a pin setter is fabricated in a modular design including a plurality of individual sections assembled to form a circular wheel frame. The sections are secured together in end-to-end relation in an arcuate manner to form a composite circular wheel. Interfacing ends are formed at opposite ends of the sections by means of flat abutting surfaces in planes radially of the circular wheel frame. Fasteners secure the sections together in a circumferential direction to clamp the flat surfaces into tight abutment.
