How to make this mitre joint fit?

Hi All,

I'm attaching 75x38 American Oak edges to a veneered MDF table top. I dry fitted the edges before glue-up and it looked good. When it came time to glue in the last piece it won't snug-up. The mating piece must have shifted when I clamped it. I'd like to trim the end of that piece (now solidly glued to the MDF), but I can't think of a way to do it neatly. Do any of you know it's done? If not, what's the least ugly way to fix this mitre?

Cheers,
Chris

You can trim it with a router and a flush-cutting bit using a piece of straight MDF/timber as a guide to run the bearing off.
Otherwise, just shorten the other piece to fit and all you'll have is a small hole to fill. The only downside is that the outside won't line up, so you'll see endgrain once it's sanded.

Thanks for the reply. After posting I was thinking about using my Festool guide rail and router to trim the mitre. If I use a ¼" bit I would only have a small section to remove by hand at the inside of the mitre. :2tsup:

Looks like the inside edge of one of those border piece mitres needs to be shaved down a bit. I would very carefully sand this on a disk sander (i made a disk that fits to my lathe's face plate and a stand that is square to the disk surface that sits on the lathe rails). My approach would be to just touch it on the sanding disk and then trial fit and then repeat until the desired result is a achieved. Using a router to do the same thing may be possible but I think there is far more chance of taking off too much material in a single pass.

Good Luck.

Unfortunately the piece that needs to be shaved down is already glued in place.

A masons mitre.

I'd go for being really really careful with a chisel.

However, if it ended up showing that I can't chisel straight lines I'd then be looking at cutting or routing out the center join of all four corners and inserting a piece of thick veneer thus making my stuffed up repair of a stuffed up assembly a feature that was intended from the beginning :rolleyes:

Sorry about that, i missed the detail in the second picture. I would second the chisel option, sneak up on it slowly and it should be fine.

Thanks for the ideas. I went with the router. It worked well. :2tsup:

I have no idea why the first pic is rotated. The original isn't. :?
