Thank you for that info. My gas tank is about 3'x2' so I don't think I will spend the time on that kind of work. I might just do like I did on this one. with the neck (or some kind of stabilizer) all the way through.
Thanks for the welcome back. I do have a question that kind of prompted my desire to rejoin. I am going to put together a fuel tank bass. Upright position of course. And I have never done that before. There doesn't seem to be much info easily accessible online. I am just curious about a good solid way to attach the neck. I think I have a good plan for everything else. I am considering using an Ebay 3/4 size stand-up bass neck.
Do you know of plans, or maybe someone who chronicled a build that is out there for me to view?
Thank you in advance for any info/advice you might have.
