Default why is centering cone needed?

I don't have one yet but I am just trying to learn a little.
Why is a centering cone needed? Why isn't the base plate just MADE TO BE CENTERED instead of being made to be inacurate? Seems like a very easy thing to do.

Its helpful for centering "new" base plates for screw holes, and when using template guides. some bit diameter to inside guide diameters can be very tight, an offset of 1/128" can mean disaster.

I can't speak for all 2nd party plate manufacturers but all the extra non (OEM) plates I ever bought don't come with alignment ribs like the PC default plates do. As tight as the (default) plates fit even they need to be checked when tight tolerances are in effect.

Never bite the hand that looks dirty!

Hi

You don't need to buy a cone you can make your own very easy and it 's a must thing you must do on all routers and mounting plates..
You can use plastic or some scrap stock from the shop.

They stamp out the base plates and most are not dead on the norm.

That is one of them "That is so simple, why didn't I think of that" little jigs, thanks for the tip... because I was wondering how do you make one without a lathe.

Ok, either I am having a "duh" moment or I'm just not that smart, but how the heck do you make those little centering guides. A hole saw? Cut out the disk and try to make a centered hole? Make the center hole and cut a circle around it? Come on, don't assume I get it cause I don't

Hi

I use the hole saw to puch them out but I do cheat a little bit, I use the jig below to get them just right and on dead center, in about 2 min. job.

Note ::you can clamp the jig on the other side of the sander as well ( the round disk side with the flat plate)
Plus it's neat and easy way to make wheels for toys or the offset rings for the brass guides..

You're Welcome sofasurfe

It's great little jig and can do many jobs..I use it all the time.
Try it with two dowel pins in place, a easy way to get a radius just right

Hole saw. Mount disc blank on its shank/mandrel. Chuck in drill press or lathe, abrade to shape with tool of choice until it fits. No jigs to make. Somewhere I have seen a really neat and simple disc sander jig. Back to the books. Nice one Bob.
