Help making frame for stained glass
I am making a large stained glass window and will need to build a frame for it soon. I have a circular saw, hand saw, drill, dremel, and various other small tools, but no table saw, router, or mitre saw. Is it a bad idea to try to use the dremel for the dado cut, then the circular saw for the 45° angles for rhe corners? I'm going for a rustic look so I don't want it to look too finished, but also don't want it to look like something a kid made.
It's 36" x 24", a stained glass-on-glass mosaic that will be over 20 lbs when finished (not including frame). I welcome any and all advice because I intend to hang it in front of my living room window and really don't want to destroy my house or window. My plan is to install some screw eye bolts in the joists and suspend from chains but if anyone has a better suggestion I'd love to hear that too.
