So, I am getting ready to start building a crokinole game board out of some boards I have on hand.  The boards are old maple flooring.  For this project, I am going to be taking the tongue and groove out.  For this, I am going to need to make some very accurate tapers.  

My plan is to make some aluminum angle gauges with a mill equipped with a DRO.  This isn’t going to be an issue.  Do you guys think this would work well with using in a thickness jig for a jack plane?  I need to make 68 pieces with a total included angle of 5.294°.  For this, I am going to need to make two sets of gauges.  Each set is going to be a pair, with the 2″ wide blade, I can do 2 boards at once.  One set at the 5.294, and another set at half of that.  The boards are not going to come to a point.  Granted, they are only going to be about 0.032″ thick at the end.  I am planning on dropping a solid piece for the center hole that is only supposed to be 5 or 6 mm deep.

Am I at least on the right track, or should I go about this an entirely different direction?  This planned method seems that it would eliminate the most time at my makerspace.  Not that I have an issue going there, but work and family time prohibit most times they are open.
