centralising my router?
I'm having real problems setting my router in the direct center of my router table. Any tips, tricks or advice would be greatly appriciated.
Many thanks
Steve

Steven have you tried to put a 1/4 or 1/2 bar,drill,etc in the collet long enough to project through the table and then move it around from there?

no I haven't tried that, however how would it be capable of moving when the router is secured under the bench?

Not sure exactly what you mean but the set up that I did was put a bar into my router,centre it to the opening,fix securely then remove the bar as you would a router bit,I think you said you had a Triton,that is good because you change the bits from the top of the router table without disturbing any settings,just wind up so the collect is up as far as it goes,you cannot get it up far enough unless it is switch off,it will then lock so you can undo it.
Hope this helps,come back if you are not sure of what I said.

I've always used a centering cone like this one,if you have a lathe you can knock one up out of wood easily.

Not a lot of info about what you are trying to do with the setup in your original question, but generally centering in a router table is not a prerequite. The only instance I can think of where it would be important would be for applications where you are using template guides mounted in the openning of a table insert and need to get the bit (and hence router) concentric to the guide. This method is used for some Router Workshop style jigs and similar processes, but is not in general use.
Otherwise the router and bit are mounted to ensure adequate clearance between bit and the table/insert openning, and fences etc are positioned relative to the bit.
One issue that often inhibits centering is the use of countersunk screws and table/insert holes. In this scenario, even if you can get the centering right, it will most likely pull out of position as the screws are tightened into their countersinks. The alternative approach is to use pan head screws with oversized counterbored recesses and screw holes in the table/insert/alternative base for the router. Then a centering cone will align the router and the screws can lock it into position. Drilling the screw holes and counterbores 3mm oversize will allow +/- 1.5mm movement for centering which should be plenty provided that you can layout and drill the holes fairly accurately.
Hope this helps.I used to be an engineer, I'm not an engineer any more, but on the really good days I can remember when I was.

Yep, centering cone. You sometimes get them with guide collar sets or replacement router bases too - check out Milescraft, I think they have some in their accessory sets, and Lee Valley also have some. But you will have to use the smallest insert in the router plate.
