I know we can make our own special use base plates like this one but I've got to tell you, for the $9.99 price tag it just isn't worth it! This is a top grade item and besides being useful for cutting mortises it gives you the advantage of having a see through base plate on your router for every day jobs!

Bought this on sale and it's well worth the price. I will agree with other reviewers about the brass pins not sliding as well as they could but it does work. you just have to make sure you hold the pins against the wood tightly as you move the router. I plan on replacing the pins with some sliding glass door track wheels or small bearings. For $ the plate with the threaded inserts is worth it as there are other things you can use it for.

Great product, that makes an easy job of mortises. Using shims on the sides of the project adds a lot of flexibility. I am sure a wedge secured properly on top would also allow different angles as well, though I have not tried it yet. Great product! Thanks again Rockler!

I built this bed using the mortising base plate from Rockler. It is a half bed (my design). This is with a coat of primer paint on it.

I made my own nylon spinning guides for $2.
THIS plate has the brass pins, not the pins with the nylon, free-spinning guides that the smaller version for compact routers has. So I'd imagine the brass pegs cause more drag on the workpiece.

SO, I went to HD and brought some #10-32 x 1 1/2" machine screws and 1" nylon spacers and made my own. Cost me about $2. The nylon spacers were in the pullout drawers next to the screws. 1 1/4" screws would have been better, but it'sounds not really important. If I can figure out how to put photos on here, I will.

It works
Works even better if you clamp some outrigger pieces to provide a more stable base.

Fast delivery. Tried it out this...
Fast delivery. Tried it out this evening. Works great. Had to drill a couple of mounting holes for my Ryobi but got lucky and was successful first try. Clamped a 3/4# piece in the vise and presto. A mortise right down the center. The base would easily get 5 stars if there were different models for different routers. No binding issues like other reviewers had. I think they may be twisting the router too tightly against the wood. It's a shame that the opening is 1 1/2" instead of 1 1/4". I could leave this plate on my router permanantly. If it had been designed to accept template bushings it would be the "perfect" base.

I also failed to read that the base wouldn't fit my Skil router, but with a little modification I had it mounted,and running. This base saved me alot of time and frustration. Thanks.

I have a craft man plunge router will it work?
Ray A on Jul 24, 2015
BEST ANSWER: The predrilled holes didn't fit my Craftsman, so I drilled my own holes, countersinked them and used beveled bolts to fasten it. Then it worked as expected.
Will this fit a Triton MOF 01 router? How do you ensure the plate is centered?

is a plunge router necessary or can this be used on a 'normal' router?
peter on Feb 7, 2016
BEST ANSWER: Yes, on a normal router.
Is a drawing available with dimensions so potential buyers can compare to their routers to see if it fits before purchasing? I have a Dewalt DW611 trim router.
AMaguire on Dec 24, 2016
BEST ANSWER: I did not find a drawing to compare with before purchase. I got mine for my Bosch Colt and the holes were dead on so the holes for the DeWalt should be also. According to the instruction sheet, it is pre-drilled for your specific router. The diameter of the plate is 5 3/4".
The picture shows the left end of the mortise about 3/4' from the end of the board. The left guide pin looks to be about 1 1/2 inches from the bit. Wouldn't the guide pin have fallen off the end of the board? I suppose you could use a test board butted to the real board but that is not what the picture shows and would be very clumbsy.
Westbend on Jul 24, 2015
BEST ANSWER: The guide as designed works well but yes you are correct that the base needs support for small boards.
Try clamping a set of longer boards on each side to get the desired dado . make sure the boards a wide enough for the clamp to fit without hissing the pins on the base.
do you offer a base for dewalt 621 plunge router?
