Hey guys.... Question....
So what have you found works best gluing up scarfed laminations to end up with good result ?
I have a method of cutting them although love to hear yours as well but my main focus is how to glue up without a multitude of issues. I am also assuming I should use epoxy to glue up
Thanks for any input guys...always appreciated :bigsmyl:
Here is how I do the scarfs,I use CA but use more than a drop, and let it stay clamped a few minutes.
It's a few pics down the way...

Very good Kenny :thumbsup:
A good rule of thumb... You want your scarf joint 7 to 1... Meaning for every inch you want the joint 7" long... Longer is always better than shorter... I make my joint on a disc sander where I clamp a board on an angle around 7 to 1 and then slide my lam into the sander until I get a feather but square edge... I clamp the pieces to a 1 1/2 x 1 1/2" piece of aluminum to make sure they are straight... Then I glue up joint and clamp it with titebond 2 wood glue... Glue sets good enough in 1 hr. to move...

Yep, you gotta have the longer joint, especially if the lam has to bend for a deflex riser... :thumbsup:
Nice little building long Kenny. JF
Thanks Jeff!
You're not that far from me Kenny. Maybe I will have to stop in and see you sometime that'd be cool. I've heard a lot about you over the years. All good. JF
Dang Jeff, now ya gonna have Roy all stirred up! Come on down! :thumbsup:
Lmao. I'm going to have to put that on a to-do list Kenny. JF
Just give a call to make sure I'm here! Hunting season is coming! :biglaugh:
For sure I'll definitely let you know the day I'm coming down that way. When it's possible. JF
Kennys method. I have a 2x4 with a rabbit that gives me a ledge to keep them straight while clamped and CA. And it they are thick I have a short sled with a hump that thins it to bend better.

Sure, you just have to read it like it was texted by big fingers on a little touch screen.
So it sounds like Stic has a chunk of wood with an open channel to register the lams against when he is glueing with super glue. And he also has a sled he uses to thin down fat lams before he grinds the scarf.

Ok but what's the rabbits name?:)
:thumbsup:
Rabbit's name is Earl, and he carries a BIG knife!
:laughing:
I was thinking the rabbit's name is Babel, but it was hard to decipher ;)
In the spirit of the OP, here is another way to get your scarf if you have a table saw, but not a disc sander.
Using the miter gauge slot, I get a 13/16" lap on .200" lams

Is this knife big enough 🤣
No mate you got to have a crocodile dundee knife

Dam yours is bigger 😅
I always have a hell of a time using my disc sander for scarf joints. I can't seem to get it to sand a taper 90 degrees.
How the heck did that knife get in this post, I'm confused. I think I have a picture of my jig for scarfing the joints. JF
