Template phay lỗ luồn dây điện cho sàn gỗ (decking)

Templates for routing holes in decking so that electrical cords can be passed through. The hole size after routing with the recommended bit will be 10mm.

Designed for a 1/4" diameter straight router bit. A cheap Ryobi bit worked fine. For bushings i used this 0.375mm router bushing from this excellent design by @hoco. The bushings fit the Milwaukee M18 2723-20 palm router on the first print.  If you don't have a centering cone yet, I recommend this centering cone by @Vincent.

This is designed for Fiberon decking with a width of about 135mm. There is some minor variance between boards, so the template may fit tight on some and loose on others. This should fit on trex and timbertech boards as well. If it doesn't, you can use negative shapes in the slicer to remove the edges, or just print and smash the edges off with a hammer. 

Trying this on a test piece first is recommended.

1. Use double sided tape to stick down the template.

2. Check that your workpiece is secured to a bench or a deck so it doesn't slide around. 

3. Route the template. I recommend several shallow passes using dust collection. i've only done this with composite decking, so there is no grain to determine routing direction. If you're doing this with wood, you'll want to route clockwise (Double check me on that - i might be misremembering).
