I've got a miter problem on my picture frame that i'm building, but before i do the glue and sawdust trick, maybe someone can tell me how i might fix it or where i went wrong. In the past, I have made 4 or 5 frames with mitered corners using the jig i made from watching the youtube guy "Woodworking for mere mortals". Jig works like a charm. Miters were perfect. On this frame, I added a 1/4 in and 1/8 in channel along with an inside cove and am going to fill the channels with epoxy resin. As the miter jig works well I'm wondering where i went wrong. Here is the process I used. Had a 2 1/2 in wide 6' long piece of poplar which i cut into 4 pcs. then i ripped each piece to 1 1/2 in wide. On my router table, I then cut my 1/4 in outside channel followed by an 1/8 in inside channel and lastly cut my inside cove. Anyway, my top and bottom rails are the same length as are the sides. The tops and sides are same thickness. I could'nt swear to this but maybe 1 piece is a 1/32 in wider than the rest. i'm gonna double check. I'm wondering if i should have cut my miters first. That gap in the one miter looks like i'm staring into the abyss. Does anyone have any suggestions as to how i might go about fixing this. Maybe i should have made my cuts in a different order? I'm not going to do anything to the frame until hopefully someone replies. Here's a couple of pics of my problem frame and a pic of one i recently completed, which turned out ok. Thanks in advance....forrest
