Thats not far short of what I do. I don't put as much bow on the channel and I use a U section style rod most of the time but your good to go with that.
What are you using as your fence there? Is the router running off the inside of the rails?
The point I made earlier about using locating pins on jigs is to avoid that 1.5mm off centre sort of thing. If I was to build a jig based on what you have there I would Have a big block of wood at the end with a pin that would locate exactly on the centre line where the strap button would go. That way you have your far point fixed and it can't go anywhere. The rest of the jig would be about setting the rails for the router cut and the slope to give the angle. An arrangement of sliding adjustable fences that can be locked down when they are in place would be my choice. I like designing jigs and spend quite a bit of time building them and refining them. Prototypes in MDF production stuff in marine ply and melamine.
I'll try and take a few shots of some of mine when I have a chance. I have a load somewhere but not on this laptop.
Are you familiar with this site it's got tons of info for all instrument makers both pro and newbies. I don't have time to post there a lot but I know a lot of the folks that do. Stick to the rules and they are a good bunch. Register and browse the library you'll be hooked.MIMF
You're correct there's a block screwed to th router base that is the same width as the blank. I'm a carpenter by trade, so I'm really into making jigs as well, and have a ton of them that are applicable to my trade. The locater pin is a great idea. That will take out the guesswork for sure. Most of my stuff I make up as I go along. Half the fun is figuring out how to do it.
The neck plays great. I was so worried that it would be a piece of shit. lol I feel a lot better now.
I've been lurking at the MIMF for a couple years. There's some great info in their archives. I registered back then, but I've never posted.
