I’ve been working on a small hanging shelf that is suppose to be testing out my new table saw: in reality it is my table saw testing me out. I made the mistake of cutting my dados with a wobble blade instead of waiting to buy an actual set of Freud dado blades- but at the time it seemed like I could get away with it. Its b/c these dados turned out so bad that I went out and bought the right kind of blade for the job I was doing. Why- WHY! So my mistake is now having dados which required some fill to help hide where the shelves don’t perfectly fit the sides and back. Most of the time I see mistakes as challenges – possible design modifications that make my project better than it would have been. But this time its a mistake that can’t be hidden, looks bad, and seems like there is no great fix. I’ve decided to continue on and try to make other parts standout to draw attention, but I’ll always see the mistake – BEN

Ben – just a few thoughts. If your are making a dado for a plywood shelf – it is often easier to do the dado with a router and bit made for that size ply. As with nominal lumber what you buy is not what you get. A 3/4 piece of ply is seldom a true 3/4. I’ve always found it fussy to mess with a dado blade and the shims to get it just right. I generally will reach for my router and bits. If I don’t have the right size bit, I make two passes to get the right size.
Aside from that, there are a couple of cheap ways to fix those gaps. If you paint your project, you can fill in the gaps with painter’s caulk and hide any unsightly gaps. It works well until you get the hang of doing dados. The other way is to cut small dado-length shims (thin offcuts) to slide into the dado and trim back with a sharp chisel. A good eye will probably notice the shim, but if you fill up with shelves with stuff then no one will notice!
I had one of those wobble dado blades. HAD. Hated that thing. Now I’ve got a regular set that sits idle most of the time because I like doing dados with my router instead.
Good luck.

Wobble blades suck, tried one once, luckly it wasn’t my blade set.
I try to do what Betsy suggests, using my router and sneaking up on the size I need.
No matter how we try to hide our mistakes, we will never forget that, that mistake is sitting there for the rest of the world to see. Even though we fixed it so know one will ever know unless we tell them. It’s almost like a guilt thing, just knowing that it’s there.
Like they say you will never be perfect without making mistakes?

I do believe there was a discussion a while back about wobble dados and it’s been pretty much agreed that they should be illegal. Too many of us have gone where you are and had the issues you’re having. It’s almost too sad to tell.
As to ‘hiding’ the less than accurate dados, you might try a face frame or a nice routed trim. If I’m envisioning your shelves correctly (that’s a 50/50 bet at best), then you could add a decorative touch while putting those gaps behind, so to speak.

I have years of mistakes floating around my house. I finish every project to the best of my ability. When I’m done if it sucks I make another one. The 2nt one is always better. The first one gets painted and given to a kid or something like that.
The very first project i made still sits on my back porch. It was messed up but I still look at with pride. I built it! The gaps, and runs in the finish, those are just character. I can point to that piece and show you what i learned.
Dark wax might help you hide some of those gaps.

this could be a good time to practice inlay’s (glue a piece of scrap in the dado and re cut)
-- Do it right the first time. Becuase fixing it is a wast of time.

Every time my dad goes through a cleanup of his shop he tries to give an old Craftsman wobble dado set, I so politely decline. My father-in law told to stay away from those things ;)

Thanks for the replys – I found all of them really helpful: I’m making a dado jig to use with my router / I’ve also inserted some small wood shavings to help fix the gaps / and last I’ve decieded to keep working on this project – it will be a good reminder of my lessons learned. Thanks again! Ben
