yeah ill post pics when i go to work on it again (i live in an apartment...so im working on it at my dads house) He has a shopsmith that i forgot about and it has a table saw, drill press, and a bunch of other stuff, so that made using the 4 inch hole saws, and cutting the wood alot easier. S i have more toold than i thought. he has a router and a few bits too, so that will be nice.

I bought a $25 carbide tipped 4" hole saw to cut into 3/4" MDF. It didn't work,

the hole saw struggled and just burnt the MDF. After the first test hole, I gave up.

If you use wood thinner than 3/4" and pine it should be alot easier. But the router

owns to cut holes if you have a jig for the exact hole size.//content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif

i bought the cheapest used hole saws i could find and used a drill press and i tore through .75 mdf, 1 inch pine, and i even tried it on some oak and it worked pretty good. just used the highest speed i could. it left pretty clean edges too.

I used the recommended 'slow' speed, it didn't work well. The advantage of

a 4" hole is you avoid the NSB frame lip but create air leaks so it will need good

sealing unless you do dipole //content.invisioncic.com/y282845/emoticons/offwall.gif.29a91b9b265d47af4b8e33fc5b558d18.gif

yeah.. there is a space around the frame.. im thinking of using epoxy or something and filling the gaps from the back before i attach the front plate to the rest of the tower( i plan to mount the speakers and wire them before i install the front baffle.)

When I made my test box I use thin weather stripping around the NSB frame

and when the screws were tightened, the foam compressed pretty good making

a decent seal. You can try it because if you don't like the results you can always

remove it without consequence.
