Maybe I don't plan ahead. Maybe I'm too impatient and just desire instant gratification. Maybe I'm just not that good at woodworking. I'm not sure, but tons of people are really bad at driving and they just keep doing it.
I'm making some games for Holiday gifts and they all have mitered sides. I have a shop made clamping jig for picture frames, but it isn't good for taller sides like these. I tried a band clamp, but there was some sliding. I moved up to some pin nails, but there was still some racking. I want this thing as square as possible (I know it won't be 100% square because life taunts me).
To the scrap bin!!
Step 1: The Material
Step 2: The Layout
Step 3: The Hole Drilling
Step 4: The Clamping
Step 5: Update: Cleanup and Modification
Lastly, as suggested by a member of the community (good call dimtick), I nipped off the back corner to allow for any glue squeeze out, which would otherwise make these blocks part of your project. Non-Super Hero Teamwork!
