Public Domain Headstock, Public Domain Body

The Bigsby headstock and Strat body are both public domain in the US, so I took the liberty of generating a mockup of a custom Silver Sky that PRS is well within their rights to make

Cheap accurate bathymetry?

Good afternoon all,

I graduated with a degree in EE, worked in sonar as related to computer engineering for a few years, and now I am interested in pursuing career options adjacent to GIS. I have access to a dirty pond with a submerged obelisk in it and want to, for a personal project to put on my resume, be able to create a bathymetric map of one of the cannon and pond floor, export it, convert it to a CAD model, and then 3D print it. With the size of the pond (similar in size to a large pool) and obelisk (about 8'x2'x2'), I think accuracy within 1" is reasonable. I need to be able to see floors and walls, but I don't need to see under the obelisk.

With my understanding of bathymetry, I either want a multibeam or forward facing array, with the multibeam likely being the cost effective option. I'm not too concerned about software requirements at this point, because I have a good enough grasp of sonar I can make some on my own, but more about hardware.

It looks like I can get away with a custom surface vessel (I've already got plans on how to do that) with a downward facing multibeam array.

TLDR; My questions are:

1 - What transducers should I look at? I want the entire sonar system to cost less than $1000. With this, would it be plausible to buy single beam transducers and DIY a multibeam array?

2 - Would it be reasonable to put the computation suite on board the small vessel, or would this need to be piped to my desktop?

3 - Am I completely out of my depths with this? I have a wide range of technical skills, but I haven't done math at this level since college

How do you personally make templates?

I've started branching out beyond the three templates I have and was wondering what you guys do to get new templates?

It seems like in order from cheapest to most expensive (which coincidentally happens to be the same order as ranking them from easiest to hardest) would be

1 - Buying templates (most of the ones I can find are pricy)

2 - Make your own CAD file and have it be laser cut for you (I don't have access to a laser cutter)

3 - Print out a paper schematic and then duplicate it

What do you guys do? I'm thinking I may take a break from historical designs and do my own thing from scratch on account of the sheer cost of templates.

Any hobby luthier's around here?

Shot in the dark, but I build electric guitars as a hobby and was looking to connect with local luthiers. I know we have some fantastic professional luthiers and shops here (Clipper Guitars, Rockbridge, Dubova, etc.), but I'm specifically hoping to meet fellow amateurs who work on instruments in their garage/basement on weekends, no sales pitch or paid work expected-just looking to join a little local maker community.

I mostly work with local woods, transparent finishes, and woodburning instead of inlays. I'm by no means an expert, but I'm always looking to learn more and one day want to start branching out to acoustics.

DM me if you are interested, Bonus points if you've got a cool project that you want to talk about.

Where to get Stingray II guitar templates?

I like the look of the EBMM Stingray II guitar and would like to build my own from scratch, albeit with a few changes.

I can't find any anywhere, so I was wondering what the best path forward is. Here are my ideas in descending order of what I think is best.

1 - Commission a custom template set. If I can find a good company, this seems my best best, but probably priciest

2 - Generate my own schematics for a template and get it laser cut. A lot of work, and I'd have to get my hands on a real Ray II.

3 - Make my own schematic, print it on paper, and hand make my own templates

4 - Use a bass template for the body. I think the Ray bass and Ray guitar might use the same body size.

Anyone with experience can point me in the right direction?
