I have a few questions that I hope I can get some advice on. I have three questions, but first some background. The picture below is what I’m working towards. This is only a portion, there are two more (simpler) parts to come. I haven’t completed the planning, so I won’t post the SketchUp file unless asked for it. My biggest hurdle is figuring out how to join the pieces together. I don’t yet have the experience to know all the possibilities. I’m trying to avoid having screws show and I don’t really want to plug any holes. I’m planning on using mostly 3/4” thick wood. Plywood and cedar.
1) How to attach the top to the side panels?
My thought was to use a 1”x1” piece of cedar underneath the top. Attached via screws going in from both directions. (The cylinders are supposed to be screws in the picture.) I don’t really like it since it seems like the final screws might be hard to get into the right place, being so close to the side panels. It seems like there might be a better method, so I’m wondering what you guys think?
2) How to attach the front lip?
I was thinking metal. A piece of angle iron cut up with a couple holes drilled into it. Again though, if there was another option…
I did think of biscuits, but I don’t have a biscuit jointer yet. The cost of the plywood for this was enough for me and I’d rather minimize any other purchases for a while. Though maybe I could borrow one. Would putting biscuits into the side of plywood be a problem? Breaking out of the layers or something?
3) Is this method good enough for the side panels?
I saw this method somewhere online and thought it might work. The center portion is 1/4” plywood that is set into a 1/4” groove. The outside frame is held together with this same groove. There were no screws in this part, it was just held together with glue. My main question here is if just the groove and glue are good enough to hold it all together? Should I put a few dowels into it in addition? I hope to do most the sides this way if it seems alright.
I know this probably isn’t described real well, so please bear with me. I’ll of course try to provide any more details that might help clarify something.
