DIY Motorcycle Stand Base Plate Blueprint - 20" x 9-1/4", 1-1/2" Sq 11ga Tube

This is a simple CAD blueprint drawing labeled "Base top view," showing the top view of a base structure fabricated from square steel tubing. The drawing depicts a cross/T-shaped arrangement of two rectangular tube members: a long vertical member and a horizontal member crossing it. Two dimensions are given: an overall vertical dimension of 20 inches and a horizontal dimension of 9 1/4 inches from the left dimension line to the vertical member. A material specification note reads "Material: 1-1/2" sq 11ga," indicating the base is to be built from 1-1/2 inch square tubing in 11-gauge wall thickness. The drawing appears to be one page of a multi-page fabrication set (other pages in the album include hinge assembly, plates, sidestand, and sidestand lift drawings), suggesting this is the base plate for a homemade motorcycle stand or lift, uploaded to the gallery of a 2006 Yamaha YZ450F. The document contains no vehicle-specific applicability information, part numbers, dates, or additional notes — a reader learns only the base geometry (20" x 9-1/4" reference dimensions) and the tubing material specification needed to fabricate the part.
