Template - Tool Board - Wall Power Extension
Whew...I was out of commission for a little over a week there, from a pretty nasty case of the flu. I only missed a couple of actual work days, but I didn't want to do anything but sleep on my days off. I also like to be feeling 100%, when working with power tools, so I gave myself a couple of extra days, before hitting the garage.
I've been wanting to move forward on a couple of new projects, but I kept feeling defeated by the power strip I mounted on my Reconfigurable Tool Rack. Here is the cheater way I ended up mounting the outlet strip--just mounted on the surface, like a wall...

I really wanted to mount the commercial 6-outlet-strip BEHIND the faceplate, but did not have any good way to make accurate holes for the actual outlets (an unusual shape to cut...1-3/8" hole with flattened ends. It is a very difficult shape to cut accurately with tools available to the average garage. Anyway, of all the options I thought of (go back a few posts...I won't repeat them here), I just had to pick one and try it...I was feeling defeated and I wanted a re-match.
Here is the previous practice piece (things become a 'practice piece' after you mess up on them--hee hee). You can go back a few posts and see the details of how I got each of those holes...

#3 actually worked out well. It came from this template I built for test-of-concept. So I knew the technique was good, but I wanted a template which required a LOT less work to line up each time...

Fast forward to tonight's 3 hours in the metalworking studio. I felt like a woodworker again (my wife even stepped out and said, "It looks like you are building a cabinet, but I cannot imagine you doing that in wood, instead of metal." I told her that I was actually working on a template. I spent a little time working with a cabinet builder and he was particularly impressed with my template-building skills and the detail I put into them. I like MDF for templates. It machines so easily, it stays flat, and lets you create nice, crisp shapes. Fortunately, I had a piece of MDF in the garage, which I bought exactly for whenever I needed to build a template. Here is the finished template, with a blank faceplate loaded (aluminum sheet, 0.125", 2 rack spaces in size (19" x 3.5")--fits in the RTR)...

I use a pair of Vice Grip 11" locking C-clamps with the swivel pads and a small block of wood to keep the piece of aluminum secured in the template...

As soon as I cut both pieces of MDF to size to build the template, I drilled four holes in the corners and inserted dowel pins, to make sure I had good indexing between the parts. It turns out I didn't need these (or even a 'bottom' board for the template) I ended up building all of the parts which really mattered in to the top piece of MDF...

So you can understand why the template is built the way it is, here is a the template-following router bit I am using for this project. It has a ball bearing to follow the template, which is located below (when the router is in your hands) the cutting edge of the bit. So, the accurate template needs to be below the piece you are cutting. Yes, that is a woodworking router bit (1/4" diam shank, 1/2" diam cutter, ball-bearing, template-following router bit)...

Here is the template again, completely assembled and loaded with a blank piece of aluminum...

Here is the complete template without any aluminum loaded. I routed the bottom and left edges straight to index the piece of aluminum. I just free-handed the top and right edges, since they are less critical. I also notched out an area at the 'squared off' corner, so that no sawdust or metal chips would keep the aluminum from indexing correctly...

A close up of the top of the template. I started with a 1-1/2" Forstner bit to cut the ends of the clearance holes, because, well, I have Forstner bits and I like to make things with craftsmanship whenever I can. In the end, it wasn't quite enough clearance on one spot, so I hacked it out with an air body saw...

Looking at the bottom of the whole template, with both the top and bottom sheets of MDF in place. This routed out area was an 'ooops.' It is in exactly the right spot, just on the wrong side of the board. Oh well, this piece is not critical. It is just there to give the ball bearing clearance...

The reverse side of the top of the template. This piece indexes the aluminum to the correct location on one side, and holds the actual hole templates on the opposite side. The bottom piece of MDF is routed out to clear all of this hardware and ends up being just more support to the template (and allows you to set the template on a flat surface and still have clearance for the ball bearing at the bottom of the pattern-following router bit)...

A close up of the actual templates. I figured that I might as well use something already available, instead of making my own. These started life as metal outlet covers. I cut off the tops and bottoms, flattened them out, marked a center line on them, and drilled two 1/4" holes in them to mount them. It looks like this one is off the center line, but that is just parallax error (you are not looking straight down at it) The way these are set up now, I can cut the entire faceplate without moving anything (all three double outlets at the same time)...

Continuing the tour with a picture of the bare base plate. I routed an area to clear the metal faceplates.

The routed faceplate. I still need to cut the holes for the switch and the LED, but that template does an amazing job of cutting the 6 outlet holes in exactly the right place. Three hours of building a template and now I can create as many of these face plates as I need. It only takes about 10 minutes to drill the initial holes and rout out the 6 outlet holes...

The new, perfectly-cut faceplate, next to the old practice piece...

Now, I just need to cut the hole for the switch, drill the hole for the LED, cut the four mounting slots, and drill and tap the hole for the ground wire, stamp the lettering, and put a uniform finish on the aluminum. I'd love to go ahead and finish it up tonight, but 5:30AM comes awfully early. Final score: Faceplate 1, Machine_Punk 'as many as he wants to make'...
