Default Base Plate Help

I have two of the small base plates from Oak Park and I need to mount one to a Mastercraft Model 54-7036-6 plunge router so I can use a OP bushing to drill some bench dog holes in a bench top I am making. I made a template out of peg board to evenly space the holes so that's why I want to use the guide bushing.
As you can see in the picture the plastic base plate that came with the router has no way to center the plate. Of course none of the holes in either OP base plate match. So how can I set this up to drill the needed holes in one of the base plates and get it centered?? I am sure this is probably easy but I'm missing something. HELP!

Hi Deb:

One way to attack this problem is to mount a 1/4 inch diameter rod in the collet and a 1/4-inch ID guide in the base. This will allow you to centre one of the base plates on the router. Then you need to transfer somehow the hole pattern from the router base to the subbase.

From the original baseplate (centre one), would the centre of the baseplate be the crossing of the diagonals between the mounting holes?

I have used the base-plate from Lee Valley Tools (Adapter Base Plate - Lee Valley Tools) for my templates. Maybe you might consider doing the same?

Thanks Cassandra. I ran into a bigger problem. Seems the OP guide bushings will not fit in the base casting of this router. The base casting is the same shape as the base plate and the opening is too small for the guides. Guess I will have to pull my bigger router out of the OP table and try that.
Looks like it's going to be one of THOSE days

Deb,
That is why I, personally, don't use OP products. They are too proprietary, or to say they won't work with anything else that isn't made by them. Maybe you can just buy a PC style 1/4" ID bushing to use for centering your base.

Hi Dep

This just my 2 cents.

It's going to be tricky anyway you do it.

This is what I would do..The base plate for the Mastercraft,put in on so 1/4' thick stock (MDF) take pencil and go around the inside of the base plate then remove the base plate and then draw a box around the copy of the drawing,then a line from corner to corner, you now have a X in the center, then drill a 1/8" hole on the X mark,,then cut the pattern out so it fits in the base plate ,once it's just right, put in on the drill press and drill a 1/4" hole in the X in the center...,,, then put the brass guide in the OP plate ( use the guide that has a 1/4" in the center) then put the Mastercraft plate down on the OP plate ,then line up both plates ( use the bit that's in the drill press to line up the plates) and then use some masking tape and stick the mastercraft plate to the OP plate ,,,( I suggest the OP plate one without all the holes) then remove the 1/4" bit and chuck up the bit for the mounting holes and drill out the holes, once you have drilled the holes out, chuck up a counter sink bit and drill out the 4 holes, then mount the Mastercraft to the OP plate..

Note ***keep in mind the handles of the Mastercraft router they must slip into the 11" hole easy..don't use the slots in the OP plate,drill new ones..

Use a 1/4" bushing with a guide pin. Put lipstick on the mounting holes on the router. This will atleast mark the holes for you.

Not understanding why the guides won't fit your router. The plate is much larger than the OP plate. Something doesn't add up. A pic of the router would be helpful.

I knew it was going to sound wacky so I took some more pictures. You can see the router base is not a "hole". The OP rings are too big. The router has a dust collection attachment that fits in those two screw holes.
This was the first router I ever bought back when I knew absolutely NOTHING about routers. I know enough now to regret buying it.

Hi Deb,

No, not wacky at all. I have a router similar to your situation. I do suggest that Bj does post some pics of the plate.

BJ it would be great if you can point me in the right direction of something that might redeem this router. Thanks!
