tennon fit checking

[Momatt]

You guys may already know this but I just learned this week.  Two framing squares and a set of stair gauges makes a handy tennon checker. We all have two framing squares at least and a set of stair gauges is under $5.  This is a 18 foot white oak 8 by 12 tie for the bottom of a king post truss.  It must go together!  I am used to furniture building and wanting tennons to fit tight, and it causes me all sorts of headaches assembling bents.  This is method of checking tennons is a handy help.  When Jim gets his tennon checker in stock again I will buy one but this works pretty good too.  I didn't think I needed a big al square until I had one and now I wouldn't be without, so I will buy a tennon checker  .
