Thin but Rigid Coping Sled

I made this sled a few months ago after getting frustrated with my earlier attempts. Either they were so thin that the jig flexed when I applied the toggle clamp, or the base was so thick that the router bit wouldn’t reach.

Finally I hit on the idea of having a handle which the material passed under to add stiffness. The clamp is mounted as near as possible to the handle so the force is directed along its axis to stop the jig bowing. I did think about having a screw clamp that passed directly through the handle, but this toggle clamp works pretty well.

I also added a sliding fence to keep the wood parallel to the rear fence, and as it turns out this is usually enough to keep the timber in place without the toggle clamp.

Love it! It’s easy to make jigs that don’t turn out to be useful, but this looks great.

Great looking jig! I love the handle on that thing—definitely no problem keeping a grip on that!

I dont see a place to mount a sacrificial back up. I fear with out a back up you will experience blowout OR do a very shallow climb cut before the main cut is made, but this is dicey.

Good point jumbojack. I could fit another toggle clamp on the left hand side of the handle, but you’re right I am compromised width-wise.

Thanks for posting. This looks like a terrific, safe way to rout small parts.

JumboJack is right about adding a sacrificial backup. This could easily be done by putting the clamp on the opposite side and then screwing a back up onto the surface of the jig that, past the edge of the jig then also extends to the table surface. That would minimize blowout.

Have your say...
