WELL it’s summer and the outdoor projects need to get done .
Here is a new way for me of making up a post blank for the round posts I need for the planter boxes I am making for our back yard arbour.
I am using 2×6 and 2×4 construction lumber for this and I am cutting a simple half dovetail joint to help align the lumber during clamp up of the post blank which also increases the gluing surface .
It’s works very well as the pieces push them self together as clamp pressure is applied in one direction only
therefore I only need about half the amount of clamps that I would normally use and it speeds up the glue up process .
When the glue is dry I will plane this post to size and forty five the corners and the turn it round.

That is a great way of gluing those up. I will have to keep that in mind if I ever need to do a post of any kind. That would help elevate the joint from separating also I would think.

This could easily be used for smaller blanks to be turned round, or even square posts for bedframes. Thank you for posting (snork) this! I added to favorites.

I hope that is a test piece because the pine or fir you have will rot out down in here in texas in one year. I would hope to use some cypress or wolmanized to stand the test of nature with all that work. Some times is better to just mill some 4×4 or 6×6 straight to acheive your goal.

Thanks for your comments guy’s !
Dennis the crack is just at the end and will be trimmed
Max the joint is very strong and self aligning and makes it very easy to glue up.
Quin this joint will also come in handy for building a box etc.
Arthouse in our part of the world wood rot is not a big problem
I just cut off a part of the old planter box I am replacing which is build of pine and twelve years old and the wood looks like new so I will be using part of it in the new planter box
I also hate treated lumber for health reasons and would rather repair the rot and I like using this style of post as I find there is less splitting and twisting this way .

Thanks again

Brilliant! I can envision some interesting uses for a joint like this.

Great joint and a use I would not have come up with. Very instructive, thanks.

Kiefer,

again, like your thinking and application here. You did this with your craftsman table saw?

Yes Thomas
This little saw did a lot of good work for me just needed a good tune up and some additions to make it my work centre, but now has found a new home with a young wood worker that fell in love with it .
Now I am starting over with the new saw but I am really enjoying it having learned things by experimenting with the old saw and the downdraft table is one I will build again .
