Built this jig so I could quickly center a mark for a mortise. In the past I would measure the width of the board and then subtract width of mortise and then mark it out (usually with mistakes and many different measurements). Now I just select the size of mortise I want and put the jig on and mark away. No math to make mistakes.

I generally build with loose tenons but this will work with integral ones also.

I made the most common sizes for which I like to use. I made one aluminum one that is 3/4”. It was a prototype and now I plan to make the rest from aluminum.

Excellent. I tend to avoid chopping mortises when possible but this will be very handy.

Nice, functional, and probably a lot less expensive than this one!

Thanks.

Yes I looked at the woodpeckers one also. I considered buying it (for less than half a second). Then after seeing how others have made thier own I decided I would make my own. Made a prototype first and it worked ok. So then went to work on this one. It works great and is very accurate.

thanks for the comments.

Quite a simple idea and making it should be a nice project.I agree it is hard to justify the asking price when you consider how easy it would be to duplicate/make your own.I figure I might even attempt it myself in the summer when my woodshop and machioe shops are finally finished ,and getting it the way I want at last after several years using it as a store for all my son’s mavchinery he was storing at my place.I just love like you guys my shops it is a great life.Alistair
