  • Some help with routing

    So I finally broke down and bought a new router. It's not the most expensive one, but it's incredible considering the Craftsman POS I came from. I need a newer/sharper bit for general cutting first. But my question is regarding cutting a recess for a plate amp. Right now it's just mounted to the sub box. I'm currently porting the box and am going to re-finish it to get rid of seams, improve the look, etc, and I figured I may as well try and recess the amp for a cleaner look. It's a Dayton 240W.

    Any tips on how to go about this? I was going to try and get the outline traced out on the box (test on a scrap piece first) and try to first route the corners using a circle jig (if I can go that small). Then I was going to clamp an edge guide on and route the straight portions, connecting the four routed circles in the corners. Is there a better way?

    I'm still learning proper techniques with a router, so thanks for any help!

    Buy an appropriate size flush trim top bearing bit (also called a pattern router bit). http://www.rockler.com/product.cfm?p...cfm?page=25160 Then all you need is to make a square frame the size of the plate and clamp it where you want. It's a good bit for odd shaped reliefs too. Just make a pattern.

      Yea, I had thought about making a template. Not sure how I will get the corners though. I need to figure out what the radii are first.

        I make a template out of 1/4" masonite and use a bit with the same radius as the corner of the plate amp. My base on the Porter Cable router uses template guides that come in various diameters. http://www.drillspot.com/products/58..._Guide_Kit?s=1

          similar to bking, i use a straight bit with the same radius as the plate amp corners, but with an edge guide/fence instead of a template. simple and works great.

            just measure it, draw a square, cut the straights with a circular say, finish with a jigsaw.

              I'll probably just use a guide and do the straights first. Then I'll see what the radii are and get a bit that is the same size. Thanks for the tips!

              BTW: Anybody know what the corner radii are on the Dayton 240W amp? :D

                3/8" if I remember correctly. Usually what I do is cut the through hole first, generally using a "frame" on the inside and making the cut with a flush trim bit. Then I place the amp in the hole, trace around the faceplate and basically go one side at a time using a straight edge lining up the bit on each end and making the pass, slowly. This seems to work perfectly.
