Alvin Drafting Machine

The Alvin TOM Drafting Machine is a functional track-type drafting machine. It is mounted on a modern and compact drawing board and features a precision ball-bearing, vertical sliding track drafting system. The vertical sliding track is equipped with a locking brake lever that allows three different positions: locked position for non-moving drawing head, braking friction position to prevent the drawing head from slipping, and unlocked position for a free-moving drawing head.
