Seeing as I was unable to get the inlaid pickup cover out of my mind, I searched until I found my original paper template, and things fell together from there.
This is largely
@Tim Barber 's fault for triggering my obsessive tendencies
Funny that I thought I'd just take some time and
just build it, but like
@Gilmourisgod I tend to run through operations over and over before ever turning on a machine or picking up a tool.
What a mind-fluff this inlaid pickup was! Doesn't seem like it on the surface, but the problem is, whenever I make any of these matching positive/negative template combinations, I always index the final piece from the
bottom. The bottom becomes my "top" when I'm working and every piece is fitted together with an identified top and bottom. The reason for this is that much as I try, I'm not a CNC machine, so my templates will always be a tiny bit off-kilter and/or asymmetrical. It's not a visible thing though, as the eye doesn't notice it if it appears true, but in practical terms it means I can't just flip a pickup over and expect it to fit into the cavity upside down - hope that makes sense. So in this case, I had to plan my operations so that I could inlay the driftwood into place and then
reliably centre the pickup cover cavity template in the correct location on the bottom. This would permit me to then index everything from the top start to finish. Good gravy I must have written this out half a dozen times and gone through each step mentally 2x more than that. Engineer, I am not.
I checked the paper template size against the first completed cover and it still seemed okay. I made a few photocopies so I'd have a few to work with.
I also sanded, thicknessed, glued, sanded, rethicknessed and resanded this block from a hunk of maple and some dark walnut.
Plus I resawed the driftwood block into a 3mm thick veneer and carefully sanded it flat. This is the top surface that had previously been epoxied with the top.
I remade the tiny inlay template using the same method as the pickup cavity template. Here's a peek of the driftwood in the planned shape.
The pickup cover is 21mm thick and will have an 18mm deep internal cavity.
Because it's so small, I don't take a chance on double sided tape and the template gets screwed down.
And a quick blast around the inside gives a small hole for an inlay! I'm leaving the natural curves that are left by the router radius and matching the inlay to them.
I glued one of the paper templates down to the driftwood piece so I could cut it on the bandsaw and shape it a bit. Side note: I bought this can of 3M Super 77 in the summer of
2004. I used it to glue foam to the inside of the body panels on my Jeep to prevent rattling. Since that time, I've used it on every template I've applied like this. It still feels like it's 1/3rd full...16 years later... weird.
A quick buzz on the bandsaw close to the line and boom.
I sanded around the edges until it fit reasonably well.
Then put CA in the cavity and slathered it in wood flour.
Then sanded it flush.
Transferred the design to the other side in preparation for routing the pickup cavity in the bottom. This was a pucker moment and I must have measured and remeasured 10x. Also marked for screw holes. I fully drilled out the screw holes between this pic and the one below.
Screwed down the template and hollowed it down for 18mm.
Came out pretty clean all things considered.
From there I roughed out the final shape on the bandsaw and mounted it to the routing template for a final cleanup.
