Tapering and Jointing Jig

Since the expiry date of my old tapering jig has exceeded, I decided to fabricate this new model that also allows to joint at the table saw or at the router table.
The parallel base is a 9” X 28” piece of 5/8” MDF on which I laid out parallel lines for five sets of 3-1/2” long 1/4” carriage bolts. The two hardwood pieces (poplar) about 5/8” X 1-1/2” X 8-3/4” act as pressure bars.
The small lower knobs are only used to level the pressure bars. The securing down pressure is applied with the larger top mounted knobs.
For repetitive cuts I’m adding a stop strip for now (photo #1), until I fabricate sliding stops to be located between the pressure bars.
To straighten edges, the same jig can also be used free hand at a router table outfitted with a
bottom bearing mounted flush trim bit or a guide bushing.

Thanks for looking.

I like the hold downs. Wondering if it could use adjustable stops to secure the piece from the side?

Great Idea. Nice and simple design. Looks very flexible. I like it. I think I’ll make one in the future even though i have a commercially build one.

Thanks for sharing.

Thank you, guys for your comments. I’m glad I built it and it should be useful for many years to come.

@SteveW: Eagle eye. I only changed my gravatar yesterday! The last time I shaved was in January. I rather be building jigs than shaving! :-)

@DocSavage45: Be patient, Thomas, because I’m thinking about adding sliding stops between the pressure bars.

@steliart: I did see yours and was inspired by it as well as some LJ’s models. One can find great stuff on LJ. Addictive as they say!
