Hi - How does everyone handle cutting the veneer to the shape of the tweeter hole?  The recess isn't deep enough to use a trim bit on the router, and doing the job by hand with a knife seems to be a bad idea. 

On my first speaker I used a trim bit to make the veneer flush with the main tweeter hole, then used a sanding bit on a dremel to open the recessed portion up, but this still wasn't perfect.

I'd like to get this done right for the rest of the cabinets

thanks again for your help.

The best way is to veneer before you router out the tweeter hole.

If I'm doing it as you say, veneer over a hole then trimming the veneer ... I just use the sanding bit on my dremel, I get it perfect every time.  The key though is a Dremel with adjustable speeds, you need to go pretty slow when you get out close to the edge.  Then just a touch of hand sanding with something like 220 grit to make it smooth.

I figured it was better to veneer then  cut the holes, but I didn't want to risk ruining the veneer as an amateur hole cutter.  If I mess the hole up and the box isn't veneered, then I've only ruined the box. 

I guess I'll have to be carefull with the dremel and finish with sandpaper.  I'm using the Oakwood Veneer Bubble-free, which is quite thick.  Hand sanding might be tricky.

Having cut many holes and veneer.

Make the cabinets cut the holes then use a rabbet bit or a carbide flush trim bit to trim the veneer.

look at router bits .com for the flush trim bit with no bearings.Just a solid carbide cutter $5.00 and the best you will spend.A small honing stone will keep this $5.00 bit sharp cutting on veneer for many years.

Here's a method I've used in the past:

Be sure to use a very high quality rabbeting bit or you'll have some tear out of the veneer.  Also, a rock hard glue line helps.

Good luck.
