Abstract
A jig for forming wooden trusses and like structures, including a table traversed by upwardly opening channels in which stop units are received to define the structure to formed. Each stop unit includes a stop and a clamp member which are adjustable to clamp elements of the channel between them and thereby fix the location of the stop along the length of the channel in which it is received. Each channel carries a scale at one side and the clamp member carries an index mark to be aligned with positions on the scale for accurately locating the stop.
