« Part 1: Simple Precision Arc Inlay Jig Part 2 of Simple Jigs and Techniques series Part 3: Matching Short Grain Veneer Border »

This is basically the same as the arc jig in the first segment but for a straight line rebate in a spot where it would be a bit of a shame to miss the target.

It starts out as a piece of 1/4” MDF glued to a piece of 1/8” plywood. The plywood is more than 1/2 the width of the router base. Use the bit you plan to use for the cut and trim the plywood using the MDF as a guide.

Now when you set up to make the cut you can see exactly where it will fall on the workpiece. No measurements need to be taken.

When I use measurements I find that there is always a way to screw them up so I avoid them with little jigs like this whenever I can. In this case I’m installing a 3/16” wide banding between a marquetry surface and a solid one. I’m using a 1/8” bit and after the first cut I will fit the one edge of the banding against the first cut and the jig tight against the other. The second pass will make a perfect fit and again I won’t have to measure anything.

I usually make these sort of jigs for a single job and chuck them when it’s done. If you keep it mark it with the router and bit size it was made with.

This jig is just common sense and probably not news to most of you but I just liked how easy it made a “high pucker factor” rebate slide by with no real sweat on my side of the router.

Thanks for looking in.

Hi Paul,
I usually go for direct quide nailed or clamped on the workpiece because of the bits cutting capacity. Those bits available here are not really long enough to route the depth I required. But good you have posted this method because I need this technique for angled cut on my recent project. I will just incline (tapering or sliding on the bit end) to my desired angle—in this case 4.5 degree inclined to produce an edge of 85.5 degrees… 40 pcs of these pieces will form a cylinder.
Thanks for the idea, Paul.

Paul: Another great tip. Now I hope I can remember it when in the trenches.

Make it just a little bigger and attach a board at the end so you can see where both sides of the router bit hit the workpiece and it will make a simple dado jig too.

It looks like the guide I see for circular saws a lot.(Edit: Oh, Jim already mentioned this.) It hadn’t occurred to me to use it for a trim router. You could also make it double-edged to accomodate two different diameter bits. Looks very useful. Thanks for sharing Paul.

I’ve used the same type of guides for my Circular Saw and larger Router & 1/2” bit. I clamp mine onto the workpiece.

The same guide here is for a Small router & bit…

Very NICE cutting guide… Very easy to setup and use…

I’m now waiting to see the wonderful creations being made by using it! LOL

Thank you.

“High pucker factor” woodworking. LOL, we have all had those moments! Thanks, Paul for a tip and a laugh!

Paul,
Good idea. I can’t seem to measure properly either.

I like it Paul. I can see that it works better to use a trim router. I will need to move that one up further on the “to Buy list”. Custom one time jigs for high value projects make for a predictable outcome.

Nice post, Paul.

Don’t you just hate those “high pucker factor” portions of a project?

Paul -

Good post, as usual. Your underlying message as well as the work of Martyn and others is to use jigs and relative measurements rather than dimensions is probably one of the true secrets of better woodworking.

Thanks!
