So, inspired by @ScottR and looking at the kind of thing owner Chris was after, I decided that it MUST be possible to make a half-decent job of binding.
The plan was to use the Stewmac Dremel guide for the bulk, and then chisels for the two areas near the neck that the guide would not be able to reach.
The Stewmac guide is....how can I put this kindly...better than nothing :
I've used it before and, while it WILL do the job where a conventional precision base won't, it does have to be used with care - mainly that of trying to keep the Dremel perfectly upright at all times.
This was the rout:
The chiselling at the upper neck join was straightforward:
The chiselling at the other side was a bit more tricky:
The binding has to actually go into the neck to end up flush
The guide follows the top surface and, at the lower horn, this rises then drops again. As such, you have to level off a small hillock on the bottom shelf of the rout
I then spent a lot of time with some scrap binding ensuring that all of the routs were level and square. Any lack of squareness leads to twists and if, for example, that happens where the binding curves back on itself, this would lead to gaps.
All done, I got a tube of UHU hart glue and stuck it :
...and that brings the project pretty much up to date other than to confirm that the stick has indeed stuck and initial scraping bodes well:
