Why do lap joints work?

If it's moisture changes causing the movement, and not something else like temperature, then could the finish play a part in allowing pieces to be transported with little difficulty? Yeah but that's where it gets even worse - instruments are only finished on the outside. The inside of a guitar for example, or a fiddle, etc. is raw wood. That's a worst case scenario for wood. To be fair - the wood does move, and guitars fall out of tune due to changes in humidity, and they are all glued together with cross braces inside, and the like, so there is an understandable reason why they don't move as much, but then there's that stuff from IKEA. I still don't understand how it holds up. The particle board, MDF, etc. used for most Ikea furniture doesn't have the cross-grain/with-the-grain diffences in expansion rates like solid wood does. Yup - somebody else mentioned that, and I had not even thought of that. Tip of the hat to the both of you. I'll sit back down with my guitar in the corner for now... -- -Mike- |

I'd like to see that myself, but she is very shy and the few times that she's been out with me when I did this song, she hated when I drew attention to her. Nice job. Thank you, but the video is really poor quality in every respect. I don't own a decent camera to do this stuff right. I have never seen a video of myself playing.

Why do lap joints work?

I used to make lots of them. Now, less because I have more tools but I still do on occasion and I wonder why they work? We all know that wood expands and contracts and lap joints have to pieces of wood doing that at right angles to each other yet they remain nice and solid. How come? Someone might say it is because each piece is narrow and doesn't move much. That is true but I've often made fairly wide laps. For example, all our toilet seats are wood, each made with four pieces about 3" wide lapped at the corners. Discussion is invited. It has to do with the better bonding of long grain faces versus the end grain which basically sucks up the glue and has poor bonding. I think it is like no on prefers butt faces. |
