I'm trying to make a rectangular box with mitered corners(like the picture below),the box is 10.1/4" X 6",(2.1/2" high),I tried cutting the miter corners on my SCMS,it was not accurate, then tried to tilt my old table saw blade to 45° but again the miter edge is not straight,tried my 12"sanding disc with it's table set at 45° so I could sand the pieces to 45 degree but the table rubs right against the disc so tight that it stops it from turning.
Now of the 3 methods I find the table saw the best for giving me the closest miter cuts but I still need to fine tune the miter ends to make them perfectly 45°.
Tried to find a simple shooting board design for miter cuts but all I could find is a whole bunch of people doing a show and tell after they have made their jig,I need to see how it is built from scratch ,Paul Seller's jig was well made but too complicated and needs special planes to cut wierd groove/dados to accommodate the fence ,the rest of the jigs on youtube do not seem to be accurate enough for my use.
If any of you has a simple design for a miter shooting board and is willing to share ,I would appreciate it if you could post it .
What I mean by simple is,it is easy to follow and build and yet accurate enough for making jewelry boxes /trinket boxes .
Your help is appreciated.
