The idea of filling the gaps from each direction on the end grain had not occurred to me on my previous repairs. Another vote for showing the repair to the gap at the baseline.

@Gotmovezlikejagga 3 жыл бұрын

@@RobCosmanWoodworking I've noticed you notch the horizontal board when inserting it into a dado, using a stopped dado. I believe you do this to ensure a crisp intersection. This avoids visible marking knife lines, saw cut marks of chipped edges from the router plane. Perhaps you could demo your process. I believe it is an improvement over running the dado to the end of the board, but it still requires precise layout, cuts and care.

Not that I ever make mistakes, but if I did this is how I'd fix them. By this time I should have ceased to be surprised by the number of KZfaq "experts" advocating the old "rubbing in sawdust and glue" hack. Moreover, they demonstrate it as a matter of course and not just for the odd slip of the saw.

Outstanding lesson. Thank you. It's nice to see you are working with your standard saw (resin handle).

Great advice, but sometime dangerous, too. :)

Awesome video, Rob!

My initial thought was to make a "shelf" in the replacement wood by sawing down into the end grain, then meet that point with a cut across from the side to make an "L". Then pare a slice of wood off with a chisel. But you pull off cutting .025" wedges like it's a piece of cake! Then you plane the chips down and are still able to walk away with the tips of your fingers in tact! :) Beautiful result, Rob. Even Jake's fine camera work can't find the repair.

The corners have something called a Swallow-Tail joint. Wish I could post a pic. Any chance at making a video to show how to make it? At first I thought they were slid together like a dovetail, but upon looking closer at the pic you can just barely see they are stacked. They look like fancy tenons. But I have no clue how to cut the tails. Would love if you could help.

What kills me is that the dovetails on this box we pretty close to be spot on! I hope I can save this box! 😅

This is a great tutorial, but it occurs to me that ( in my nonprofessional opinion ) the procedures called for with the first fix herein require a level of craftsmanship and detail work two steps above those necessary for the cutting of the dovetails. If I tried to recut the side of a tail, that I couldn't cut straight the first time around, I'm going to end up with the Mariana Trench on the side of my project. For me, the best fix would be to cut a small end grain wedge to pound into the original error, and rely on the wood to compress if needed.
