This is all great! I do not have any intonation or “wolfe” tone issues, so that is a plus. Not much in the budget for this job, so I am going to try some strings first before I go the routing option. I have a raiser if I need it for the bridge to help balance volume.
First of all, let my start by saying that the following procedure is not necessarily something I recommend. It can be a bit risky, if you're not careful. But it's also a VERY fast way of routing holes in pickguards, which can save some time (and money...).
Anyway, if you only need to route a hole in the pickguard (not the body) you can save a LOT of time by using a Dremel with a router bit, instead of the rather time consuming procedure of making a template for a proper router. I used a Dremel router bit that's designed specifically for plastic/plexi glass. I don't remember the parts number but it looks kinda like a small drill bit.
You will need a steady hand and nerves of steel though! The bit will drag sideways, often in sudden jolts. The key to success is to leave a good safety margin and remove the remaining material manually, using files. This can be done relatively fast. Certainly a LOT faster than making a template.
Don't use the Dremel at full speed though. The pickguard will melt and sparks will be flying! Slightly below half speed should be fine (although I should probably mention that I've never tested this method with on vintage celluloid pickguards, you really don't want THAT material to catch fire!!!).
I've done this on many occasions to save some time. I've not even used those router attachments you can get for Dremels. Just 100% freehand. I've ALMOST messed it up a couple of times, because of those sudden sideway jolts. But it has always turned out great. Just leave a good safety margin, go slowly and leave the final millimeter (or so...) for the files.
Of course there are other methods, like drilling out holes and using files for the rest. But the Dremel method has been BY FAR the fastest in my experience. But perhaps also the most risky...
Like I said, I don't necessarily recommend this method... but it's certainly a LOT faster then making a template! With a relatively easy shape like these gold foils you should be able to do it in 10-15 mins.
