Router beveling question

[vaderag]

I'm building my cab (OND design) currently and I'm thinking through the bezel creation and it's hurting my head

I have a hole cut that is the right size for the monitor and I want to bevel the edge.
The plans also suggest routing the back to make a spot for the monitor to sit... They suggest bevelling first and then routing the back, but in my head that will end up with the hole bigger as you'll route away some of the bevelling at the edge... Am I right?

Also, my other issue is that I want to put hard right angles in the corners... I can't work out if I can get away with bevelling with the router the whole way around and then chiselling or if I need to leave the corners entirely and then chisel in?

Any help appreciated... I feel like I might be over thinking it, but I want to get it right!! Thanks

Cut the hole a little smaller than the final size.  That way when you bevel the cut then carve the step in back, it's the correct size.

Too late, hole is already cut to perfect size (barring corners which are round currently but plan to right angle...)

In that case you might want to just glue in some 1/2" strips on the backside of the bezel to make a pocket for the tube.  Just an idea.  Good luck.

I use a chamfer bit with a bottom bearing so I can follow the edge.

That's exactly what I have... That'll leave a lip tho, surely?

That's my backup option...
I guess other option is to recess the back first then bezel. Will reduce the depth of the bezel tho I guess maybe not looking so good?

Use plywood, MDF or hardboard to create a template to give the bearing something to follow.  Make sure the edges of the template are sanded smooth or the imperfections of the template will transfer to the final product.

Cool, that was my plan (tho was going to clamp and do each side at a time)

Re the corners, tho, should I go right in there then chisel out, or leave an inch spare and chisel from there?

I typically do a full template and run the router around twice. Once shallow and then full contact with the template.

The corners will come out on their own, but if you have some scrap, I recommend you test it first so you can see what you will get.
