Rounding out both sides of driver hole?

[bean438]

Up until now I have been rounding out both sides of the baffle driver cut outs. It cleans up nice and make it look like I actually have a clue what I am doing.

But it got me thinking if this is a good practice or not in terms of a proper gasket seal for the driver to baffle.

I know you can round over the front for a rear mount, and the back side for a surface mount.

Is it OK to round over both sides, regardless of fron or rear mount?

I wouldn't.

Cut the hole a tad smaller if you want to round the front. I wouldn't round the back.

Rounding both leaves not enough wood for the driver mounting screws to grab.

The bad news is I have to recut and re drill all my baffles then.

The good news is that I get to play more with my new Festool plunge saw and guide rail!
