I use aluminium angle extrusion. Easy to rough out with shears and finish with a file. They get screwed directly onto the work surface so template and foam have a common datum. You really need 4 per section, upper and lower surfaces on both left and right. These are finished in left/right pairs. -harold =?iso-8859-1?q?Brad=20Willoughby?= ([EMAIL PROTECTED]) wrote: : Daniel, : Yet another material for core cutting templates: sheet metal.
