Making flat frame is harder than you think. The miters have to be perfect or you will see the gaps in the counters. I just started making them and with everyone I’m getting a little better.
The frame is only miter together, with end grain to grain. This is not a strong joint. You want to make the joint stronger. There are a few opinions, adding splines, nail gun, add biscuits, dovetail keys or half-lap miters. These are just some ways you can add strength to the miter joint. Depending on the way you want to you strengthen your miter, it may alter a few of these steps.
Step 1: Ripping and Cutting Out Notch
I ripped the wood down to 3 inches wide on the table saw. Now I have two pieces wood are cut to same size. I like to cut down the piece to about the size that they are going to be on the chop saw.
The glass has to set somewhere; we are going to cut this out a notch with the table saw. When you are detriment the depth of the cut, need glass and a backer board to fit, with tabs to keeps the glass in place. I run the vertical cut 1st, raise the blade up to about ¾ high and set the fence. This will change with each frame. Run each one of the board thru. You have just made a rabbit. Lower the blade and move the fence over to cut the out the rest.
