Thread: Planing perfect dados

Ian wins. It can't be a perfect dado now since you made it before the tenon.

Perhaps it is the ULTIMATE dado - a dado made before it's mate and yet it still fits perfectly!!

Ray, what is interesting for me is that the plane in the video is traceable to a plough plane I built. In fact, there have been a few of these planes built based on my bridle plough ...



Here is an article about this (on the unpluggedwoodworker's blog):

I'm away for a few weeks, but will be back to meet this challenge with the next chapter!

you are missing the point -- I am having a bit of fun with Derek around the word "perfect", which I'm sure he totally understands.

dados, like mortises should always be cut before their mating tenons -- mostly because it's easy to fix a poorly mis-cut tenon, and much more difficult to fix a poorly cut mortise.
If a mortise is slightly out of position or out of square, the "fix" is to cut the mating tenon so that when the parts are assembled, the error in the mortise is cancelled out.

Derek has no need to make any tenons to fit his dados, unless he is going to try three different ways to cut them.

You're right kinda.

I didn't miss the point - I got it completely backwards.

For some reason I was thinking the tenon is first. I know better than that.

But I was thinking you won as making a perfect fitting tenon still wouldn't mean the dado was perfect.

Edit: (Following your idea that a dado is only perfect in relation to the tenon I was being silly and saying the dado can't be perfect if it's cut first because you can't cut it to fit the tenon so I guess I effectively missed the point. Still that means 'Ian wins' is now a valid statement)

Unfortunately it's the sort of thing I do often. Understand far better than my execution would make it seem that is.

It was nice to see some tangential banter

Sorry Ian, changed it a little after you read it.

Full disclosure: Attempting to be more 'myself' but it will take a few goes to find a balance between overanalysing to try to come across as normal and spontaneously blurting out things that make sense only to me. I'm very ADHD

Edit, There's also the tendency of not knowing when to stop talking
