Rockler Compact Router Mortise Centering Base

With this ingenious router baseplate installed on your compact plunge router, perfectly centered mortises on the edge of your workpiece couldn't be simpler to achieve. Just rotate your router until the included guide pins contact both faces of your workpiece, then plunge and rout. The pins are positioned in threaded inserts to adapt to a range of stock thicknesses up to a maximum of 4''. If you need to cut an offset mortise, simply clamp a board equal to the thickness of the offset to one side of your workpiece.  Base is pre-drilled for Bosch, Dewalt and Porter-Cable compact plunge routers (#41770 and #41462, sold separately).

Needs work.
The base works well for sign making. I use it on my Dewalt router. The holes line up correctly for the guide bushings. The mortis pins need to be spaced differently. Hard to hold perpendicular to the end of a board.

Centering router base
I've found the clear, centering base to be very helpful for cutting mortises.

Worked perfect
Could not have been more pleased. Checked against 3 scrap pieces and it was center every time. No more spending un-necessary time trying to find center line, I drew top and bottom lines for the mortise and cut. I used my Bosch Colt 20 EVS with the plunge attachment. To help some of you guys out, on the instruction sheet it has the Colt20EVSPK, Porter Cable 450PK and DeWalt DWP611PK.

worked well, but would like to see the pins sleeve to be able to rotate to eliminate drag and unscrewing the pins.

Great jig
I had previously used a shop made jig that was acceptable, however this far surpassed my shop made unit both inaccuracy and ease of use

i had to layout and drill holes to mount my makita plunge router,too bad the mfg. did not include hole paterns for more routers. the plate worked fine,though you must be careful to maintain pressure on the pins or the router will wander off center

Centering Base
Nice base,however, it does not fit my Craftsman router. However, I was able to carefully center it on my router and drill the three holes necessary to attach it. It works fine to rout the mortise.

Does not fit the new Bosch Colt or the compact Ridgid palm router etc etc
I own 4 routers with 6 bases. This base fits none of them. I guess it was my mistake but I assumed it would fit a majority of routers. Come to find it out only fits 3 and must be specific, as in, it will fit one kind of Bosch Colt but not the other. Very annoying when all they had to do was drill one more set of holes to allow far more options.

inexpensive way to mortise a pull in the edge of pocket door, i hope.
Works great! Fits my DW611 perfectly.
Fred F on Feb 24, 2017
simple base I can use double stick tape to apply to router, rather than drill holes for each router.

Thought it would be a better option to start out with rather than purchasing a mortising machine.

Bill L on Sep 28, 2016
This looks like a very good and versatile option to trying to center mortises in project parts.
Jack M on Mar 9, 2016
I plan on using it for my mortise and tenon jig, the reason why is the opening in the bottom of my current router has to big of an opening for the bushings in that kit.
Charles J on Mar 5, 2016
I am hoping this will be easier to make my mortises than the lengthy set up at my router table.

Can you use a groove router bit to make grab points on the edge of a thick cutting board/butcher block?
Steven H on Jan 2, 2016
BEST ANSWER: I have never used the base in that way! The item can be used on a variety of board widths and have used it that way successfully. Your question is interesting however I am not sure it was designed with that application in mind.
Will this work with 1/4" drill master trim router?
Robert G on Jan 16, 2016
BEST ANSWER: I purchased this item for my Bosch Colt router, I am not familiar with the drill master

Thanks, Thom
I have a Bosch compact router, but it is not a plunge router. Will this base still work without too much trouble adjusting depths?
Jack O on Mar 18, 2018
BEST ANSWER: If it has the same base it should work just fine
Will this fit Ridgid compact router R2401? thank you
scott c on Aug 1, 2016
BEST ANSWER: Can't answer that specific question. I bought mine for a Bosche however that app works very well. Sure beats a fence or other method of alignment. Seems to be fairly universal ( has multiple mounting holes) as well.
