Above table router adjustment

[ndj]

I may be wrong about this (which isn't at all uncommon), but I thought that I had read somewhere on this board about some folks who are using above table adjustments on their routers attached to the BT3's accessory table. Whether it is with an aftermarket lift system or with the system on their router.

My question is (see that I'm a Newbie), if this is so, how is it being done? I have a Bosch 1617 mounted to my accessory table in which I had to modify the mounting plate to attach it. As I see it, in order to access my above table micro adjustment, I would have to drill a new hole through the accessory table itself as well as a matching hole in the mounting plate so as to access the adjustment on the router.

Is this what others have done? Or am I just wrong and no one is doing this with their tables? Is this recommended at all? Any comments would be welcome. Thanks!

yes, I had to drill a hole.
It wasn't real easy to locate the hole but it wasn't real hard, either.
You can't mark the hole directly since the extended shaft fills the hole.
With the router base mounted to the table or mounting plate, I took a straight edge and sighted lines pointing at the center of the adjustment hole from about four angles outside the base. Then I removed the base and extended the lines - they should all intersect at the location for the hole. Drill there.

Thanks LCHIEN. That makes sense to me. I'm assuming that you drilled initially from the bottom of the table and and then went back with a countersink for the top. Is that correct?

I just drilled a straight hole, I think 3/16th" for the t-wrench. - I debated a smaller hole but decided to use that because that is the diameter of the hole in the base. I was worried about dust buildup - too small a hole might help reduce buildup but would make it hard to clean/blow out.
I did use a brad point wood bit in my phenolic table insert (mounted in a router table, not BT). and I did drill from the bottom until the tip protruded from the other side, then flipped the phenolic plate over to drill from that side to prevent any chip out.
I didn't use a countersink save to break the sharp edge a little.
