I'm going to make a box, 2 cf @ 32hz for a pair of Powerbass 10's. I'm just going to kerf the port opening.

Step 1: Set the blade depth. I highly suggest having a scrap piece to test with. Should be like 7/8ths or 15/16ths deep. Just barely enough to keep it intact, otherwise it won't bend.

Scrap wood:

Step 2: Make cuts every 1/2" for ~5" (10 cuts) for a 90 degree bend. I made 6" worth of cuts and it was too many.

The wood should take a little force to bend, but once the wood gives a little, it should bend freely.

More coming later this afternoon.

won't make much of a huge sound difference... less port noise. main reason for doing it is that it looks cool.

cool beans.

if it were me, i would then proceed to bend the cuts open a little bit and apply copious amounts of kitty hair in the gaps... immediately after which i would have the box ready for the installation of this port, and bend it to the right specs and clamp it in place to dry as i wiped off the excess body filler - it would all need to be done in a few minutes because kittyhair\bondo dries quite fast. would prolly need to people to get the job done.

just thought i would ad my 2 cents.

i have the ryobi portable one. its great.

one time, i cut off power to the neighborhood with it. true story.

a piece of MDF got turned a hair too far sideways during a freehand cut. The blade stalled, and the power went out. :laugh:

it can be stationary. i'm just saying it's pretty light. i always take it outside as to not get MDF dust all over my dads harley.

shop is not at my house
