I made this corner spline jig a few years ago and man, it's been a lifesaver.....  Accuracy is very good.  

Just thought I'd share in case anybody wanted to make one...

That's really neat!

 

I notice the "bottom" of the cuts are very square. Do you use a specially ground blade for this?

Yes, I use a Forrest Woodworker II #1 grind for my 1/8" spline work..It produces a flat bottom kerf.  

most excellent...

thanks..

Thanks!

Very nice.   A lot fancier than any of mine

 

Accuracy is "very good"?

Looks closer than that to me!

Thanks for the pics,

NICE...! ! !

 

Great idea for the metal rules...and all the alignment marks...

Great job! Very useful jig.

That's just the cat's meow. Thanks for the great photos. The construction of the jig seems fairly straight forward and, I can see how it's used to create the splines. But, I'm a bit fuzzy on the alignment procedures. 

If you have the time and the inclination, could you maybe walk us through a couple cuts?  I just don't have the necessary visualization aptitude. 

Thanks for showing us this neat device.

+1 on this. Great jig. Lots of questions, but let's start with a walk-through of the operations and set-ups, which will probably answer most of those.That is if you have the time, Edward.

Trying to figure out all the features of this.   Here's my guess:

- the rulers tell you distance to center (?) of cut for various blade widths.

- you set the stop block for the required distance for the widest insert 

- for multiple splines like shown, you cut the widest one first, then insert the spline, let it set up*

- change the stop setting to the next narrowest one, change blades

- repeat the fill and cut as needed/desired

 

* you have to reset the distance because one side of every blade will be flush against the arbor stop.

 

Do I get at least a B ?

Basically, you simply line up the stop block that is mounted on the slide to the measurement on the ruler.  Lock it down with the wing nut, and if you have a large box you can lock down the box with the toggle clamp....  but, i don't use the toggle clamp very often.  Nice to have if needed.

 

Different rules as different size blades index differently. 

 

Quite simple to use and very stable and accurate. 

Blade indexes on the left side of the kerf.  Otherwise, you got it.

Then you have a left tilt.   Some saws are right tilt.

Yes. 

You can also do angled splines....  I would recommend using a test piece though, as the angles act a bit weird...

 

Many thanks for everyone's explanations. These posts are invaluable. They've been saved. When I get the jig built, I may revisit you guys for more help. Ya'll are great.
