I made this jig about 4 months ago wanting to attempt miter splines in a special keepsake box I was working on. The cradle was made rather large compared to many I seen due to possible larger projects down the line (trying to think ahead). I used slides in both miter slots to ensure good tracking as well. I made a removable stop that is easily held in place with two small clamps and use a recycled section of an old tape measure for distance of cut. Last but not least I added a handle to ensure my fingers will stay well away from the blade (I have grown attached to

Nothing super fancy. Just a good solid, dependable jig I can always count on. Thanks for taking a look.

Less chance of spacing errors - dead center -

RLWJr RLWJr writes: Nice jig, but the web people ought to correct the link. This is described at the link to the page as a PLANER jig. I was wondering how I could use a planer for this joint! It is, of course, a tablesaw jig. But a much nicer one than what I have been using for years!
