Saddle Routing Jig

About This Item

Fast, accurate saddle installations! Slot an acoustic guitar bridge easily and accurately every time. A StewMac exclusive.

We designed this handy jig here in our shops, to solve the tricky router alignment problems you'll encounter when creating or correcting a bridge saddle slot.

It's become a repair shop "must-have," with versatile time-saving uses that will give you easy, accurate results every time.

Slot a new bridge
Slot for a compensated saddle—split saddles too!
Fix an incorrectly located saddle
Flatten the bottom of a slot for an undersaddle pickup
  (crucial for proper pickup response)

The jig works seamlessly with our Precision Router Base and your Dremel. Don't have a Dremel? An adapter for the popular Bosch Colt router is also included (you can drill it to fit other brands of laminate trimmers, too).

Simply clamp the jig at the guitar's soundhole and tailblock. It's made of clear acrylic for easy positioning, with sponge padding to help level the jig on arched soundboards. Thumbscrews allow precise fingertip adjustment of cutter alignment, saddle compensation, slot length and width. Clear acrylic adapter plates are included.

Instructions are supplied with the jig. Clamps, router base and Dremel not included.

TIP: Before using the jig, you'll need to know precisely where to rout. The Saddlematic and the Intonator take away the guesswork.

Great tool!

Customer wanted to replace the cracked and lifted bridge on his '65 left hand Gibson LG-1. Since it was left hand, I had to install the #4927 unslotted/undrilled pyramid bridge.
It was my first time using this jig, so I practiced on a junk guitar first. Watched Dan's video of his LG-2 project (thanks Dan!), and followed his advice of making plunge cuts. A new bone saddle popped right in after final shaping and intonating by hand. Plays great!

Saddle Router

By
(Customer's Reviews)


This is the second saddle slotting jig I've purchased from StewMac, the first one was years ago and not as well developed and did not fit the StewMac Dremel router base well. I had problems keeping the router base properly oriented over the bridge. I bought this one because they seem to have addressed those issues. With this version my StewMac Dremel routing base fits nicely into the jig and
the tolerances are reasonably tight. I would prefer routing with a better router but the size of most laminate routers makes it difficult to manage in a small area like the bridge saddle slot. I've never trusted the bearings on a Dremel but if it's fairly new, the bearing are not badly worn and a good saddle slot can be cut. But buy the down-cutting burs. Others will wander and chip, it's one of those operations that has a very high pucker factor, this jig helps reduce the stress. Still requires your complete attention! And, like most things, it's all in the prep.

Good but not perfect

By

I have been using this jig many years now. The concept for the jig is great! The Dremel is not a great tool, to much play. Work best if you drill your way (by tilting the Dremel and drill a row of half "holes" with the router bit) in the middle of the slot and then use feeler gauges and the guide to route both sides of the slot, just kissing the wood.

Recently I found out that the acrylics in the jig was not as flat as they should be. I've been having some problems not getting the slot flat in the bottom. Flattened all the acrylics with my drum sander, the screws was easy to remove. I also noticed that the acrylic was not as stable as it should be. Even the weight of my small Dremel will bend the acrylic frame a bit. When using clamps and if the top of the guitar has an arc, the jig will follow the curve. And the bottom of the slot will follow to.

I have now reinforced the topmost frame with a steel sheet. I clamp it to the center and use thin slivers of wood to fill up the gaps between the guitar top and the underside of the jig before I do the routing. Now and only now the bottom of the slot is dead flat.

The shape an form of the jig is perfect, the material should be aluminum or some other metal instead of acrylic. That would be very nice!

I give my improved version of the jig and the method to use it five stars.

Makes a time-consuming job very fast...but

I agree with Ben from Austin, don't use your Dremel - use your trim router. The jig comes with a pre-drilled base to fit the Bosch Colt and this is much more solid.

The problem with trying this job with the Precision Router Base and a Dremel is that the router base adjustment is a two-wheel affair that permits there to be the slightest tilt to one side or the other when adjusting the cut depth. This means your slot will be larger than the router bit and, even, worse, may end up with uneven ridges on the inside edge.

If you're stuck with having to use the Dremel. make sure the fixing screws on the router base are good and tight to minimize flexing.

Oh yes, and one other thing StewMac; can you improve the fit of the Dremel tool to the base? Some sort of locking system would make the whole thing more usable.

Great Jig, but not seamless with Precision Router Base.

By

I think that both the Saddle Routing Jig and the Precision Router Base are very well made, and on a whole, are time savers. The rating I would give each individually would be five stars. The problem I have had comes when I use the Saddle Slotting Jig in conjunction with the Precision Router Jig to cut saddle slots. There is still enough wobble within the Dremel that the bits end up cutting a channel that is .018 oversized from the StewMac Carbide Downcut Bits (which are also a great part). This clearly means that if you use the 3/32 (.094) bit, you end up with a channel that is .112, and if you use the 1/8 (.125) bit, you end up with a channel that is .143 wide. I have talked to the folks at StewMac, who were very friendly, and they recommend I use my trim router, which I will do in the future. However, I disagree with StewMac's claim of the Saddle Slotting Jig working seamlessly with the Precision Router Base. Again, both are very well made, I have just found that they do not create an accurate slot width.

I just used my new saddle routing jig on an acoustic that came in to the shop with a broken bridge plate and a missing saddle. Set up was easy and quick once I had the rout marked out, and the job was over and done quickly. You do have to be very careful when tilting the router bit into the plate.

The price of this tool makes it worth buying. If you want to make a similar jig it might cost a lot less in materials, but will take a lot of time you could be spending doing other stuff. its easy to use and accurate. i used it with my bosch router. theres a few tricks you need to know while using the tool so if you arent experienced maybe do a test run on a scrap bridge to get a feel for the router and how it cuts in the jig.

This flexible jig has saved me countless hours piecing together jigs on a case-by-case basis, or in developing my own permanent jig.
Quick, accurate and repeatable results.

Works Great with the Bosch Colt

By
(Customer's Reviews)


This jig works great with the Bosch Colt router. Drill a 1/16" hole at the saddle locations at the e-strings' pin holes. Use your holes for aligning the jig. Then mill your slot in 2 or 3 passes with a 1/16" downcut bit. Make one final pass at full length and depth with the 3/32" for a nice and clean saddle slot.
