Trying t figure out what I need to make a Leigh RTJ400 dovetail jig work with a Bosch 1671EVSPK router mounted in a Bosch RA1181 table. Dovetail jig requires a 1-3/8’’ Porter-Cable style insert ring to fit the Leigh bushing. Haven’t been able to find an insert that size that says it will work with my table, but the info is confusing. Anybody out there have this combo, and if so, what did you have to buy/make to make it work?

I don’t have the router table jig. Mine’s an older D4. However, I do know that Leigh has great customer service. I’m sure if you contact them, they will walk you through it.

Can’t help… but I do notice that on the RA1181 product page, it says that it will not accept any template guides, so you may be SOL.

Cheers,
Brad

One time in a pinch, I added a sub-top to my table with a recess cut into the underside to fit a bushing guide.
Basically a layer of MDF the size of my table top, recess drilled with a forstner bit, aligned to my router.

I have the same router, but different router table and dovetail jig.

Just to make sure I’m clear, are you talking about the base plate for the router itself (to fit the guide bushing) or the router table insert plate? Sorry if that’s a dumb question but I’m not the brightest crayon in the box. Assuming it’s the latter I know Jessem makes one.

Looks like you may have to make your own insert plate. This is the sort of thing I use my 3D printer for. The biggest problem may be figuring out how to deal with the tabs that hold it down.

I emailed Leigh and was told that Bosch does not make, and does not intend to make, an insert ring for any of their tables. They also provided information from another customer who had bought a table insert plate from Kreg that is drilled for an insert ring. That insert plate is slightly larger than the recess in the Bosch table, but I received it today and it was a matter of trimming 1/8” off the sides and one edge to make it fit. It was predrilled for my router, but I had to drill 4 holes in the corners to attach it. Good to go after about 30 minutes. Leigh dovetail jig also just arrived, haven’t even got it out of the box yet.

I did a quick search on thingiverse and someone has made some inserts for 3D printing. It doesn’t look like they made one for a guide bushing but it might not be too difficult to modify one of the ones they did already design. There IS a remix that looks like it is intended for drilling out your own hole so that one might be an option. It probably would not be too difficult to modify one of these to have the correct size hole for the bushing.

Just to see if I could, I decided to see if I could modify the above insert on Thingiverse to accept a guide bushing. After spending several hours learning OpenSCAD (it is more like a programing language than a CAD program), I managed to modify it for a guide bushing. Here is the result.

Of course this is based upon my Harbor Freight Guide bushings and since I don’t have a Bosch router table I didn’t print it.

I decide to post my 3D printer Bosch router plate design to Thingiverse in case others might be able to use it. I haven’t actually printed one myself since I don’t have a use for it but if you have a friend with a printer you can give it a try. The cost of filament will probably be less than $1. I cannot guaranteed that it will actually fit your router table. You can click the Customizer link to make the recess fit your bushings. You may have to sign up for a free Thingiverse membership to use Customizer or download the STL or OpenSCAD files. Note that the Leigh manual says that the depth needed for the recess for the bushing needs to be 0.10” deep and my default parameter are slightly shallower to match my HF bushings. It might not be a bad idea to make it a few hundredths deeper than 0.10” just in case.

I made my own router base for my Bosch Colt router because the factory one wasn’t flat and did accommodate bushings.
  1. 1/4” polycarbonate from Tap Plastics
  2. drilled a 1/4” hole located far enough from the edge for a good size base
  3. installed a 1/4” drill blank in the router collet
  4. transfer punched the Colt muting holes
  5. cut the polycarbonate todesired size desired
  6. cut the recess my Porter Cable bushings.

Did not need a printer … but it would have been nice!
