Made a simple spline miter jig out of 3/4 MDF. Must give credit to Ken (http://lumberjocks.com/projects/38361) for the design idea.

Gul, I must confess I haven’t given it a test drive yet so it can certainly end up a disaster. Scrap MDF so no harm, no foul.

My kind of jig. Simple, cheap and throw away.
I really don’t get the elaborate ones.
Nice one, it will work just fine.

This looks GREAT! How thick will you make your splines?

I bought a pick-up load of mixed hardwood yesterday that a guy wanted out of his garage. ($44.00 but that’s another story) In this pile was a plywood miter jig. It came out of my pick-up and into the burn pile. A few hours later, after sorting thru my deal of the day, I started cutting on a few choice pieces to make some keepsake boxes for Christmas gifts. I went back to the burn pile, retrieved the jig, and after some minor changes, (removed the drywall screws) I was able to use it to spline my boxes. The jig lost a lot of support because it rode on the table as well as against the fence. I think I’ll have to copy yours so that it rides on the fence.

Did you have any problems screwing into the edges of the MDF , such as splitting or stripping ?
Did you use glue as well as screws ?
thanks

Sanman, I’m going to experiment a little since splines are a new area for me. I made the section that rides on the fence slightly bigger so I probably have about a 1/16th or an 1/8th inch of play. In the end, by changing how I push the jig through, I can make probably a 2x full kerf thickness spline, without adjusting the fence

Boxcarmarty, sounds like a great find on the wood.

Dustry56, I predrilled all the holes before I screwed them so fortunately no splitting or stripping. I didn’t glue anything, it’s actually quite strong without, given that it rides on the table and the fence, there’s really no hard stress points on it.
