A few weeks ago, I saw a really cool miter spline cutting sled in a catalog, and worked out a design based on that sled to make for myself. I blogged about it here, and posted screen shots of my sketchup model

Here is the finished sled…

I stayed with the MDF, and I ended up using 5/8 Baltic birch for my runners. I glued everything together and shot it with a combination of 1” and 1-1/4” brad nails.

The T Track is from Rockler, and I bought a set of bolts, washers and star knobs on sale at Woodcraft for $4.99

It came out real nice…everything is perfectly aligned for spline kerf cutting. I am going to use an outside saw from my dado set to make a 1/8” kerf at 90 degrees and one at 30 degrees as well. I want to use the saws from my dado set so I get flat bottomed kerfs. The sled in the catalog was priced at over $100.00. I think out of pocket, for the T track and knobs I spent $12.00-$15.00. Even if you add in the glue, brads, and MDF it’s still gonna come in at under $40….not bad..I can’t wait to try it out!

This is really sweet. Makes the one I cobbled together look like… Well, Cobbled together! Mine is actually not a sled. I have to screw it my miter gauge when I use it. Yours is top notch.

This is a great looking jig, David. It is one of the nicest looking spline sleds I have seen. Being able to adjust it for different sized boxes is a plus in my book as well. I have been meaning to re-do mine and your certainly gives me some ideas.

Nice job David, It looks almost as my own version:

$100 is way too much for an idea you can find for free over here and do it yourself.

I got the inspiration from other proyects in here, and I can’t stop to think they did the same without giving any credit care to share the company name?

Thanks for sharing!

I’m adding this idea to my favorite’s list. Not only is it a low price option, but it will accomodate several sizes of boxes while holding them securely. Your version is very well done!
