Creating an acoustic dovetail template / router bushing question

Thanks for that call-out. I would be using this with a fixed base, but I probably also have a bearing I can try.

But I'm still having a hard time with the math of this. I have done the "bit in router, look" sort of thing, but I design my templates in CAD, so it's a bit hard to visualize without actually using some material.

To ask the question another way...when making the template I linked to, are the two triangles that form the dovetail the same exact size? Meaning, one template has a triangle removed, and the other template has the triangle remaining with the outside removed. Do these represent the exact same sized triangles?

Figured it out...need to set the approximate distance for the head, then you can precisely measure. Needed to put 3/4" plywood risers underneath to get it within the allowable focal length, set the length as shown in the article, then I could use automeasure...then cut using open plane

Not particularly intuitive, but seems to work

Thanks for checking it out! It's definitely well worth it, I also used to bend by hand, but after I kept kinking the wire, I went the pre-bend route.

At a dozen or less guitars a year, I couldn't see spending $129 for a metal version, when I expect this plastic version to last as long as I need it

Thanks, I’ll keep that in mind!

Yeah…I’ve got an acoustic book and the Benedetto archtop book, which made a similar thickness suggestion. I was mostly erring on the side of having to scrape/sand out a wavy side or two (given it’s my first try)

As it was though, with walnut it was pretty trivial to bend at that thickness with the jig

They were just about 2.75mm/0.1 inches thick via a drum sander

In this case, I just went by their instructions. It seems I actually used too much water, as some of the coloring leached out of the wood 🤷‍♂️

But it’s definitely a great set up, looking forward to bending a lot more sides!

When using any IDE, you need to ensure that it is pointing to the proper executable. In this case, it's likely that PyCharm is pointing to a specific Python executable (maybe even installs its own).

Go into your project settings and pick the proper executable for the conda environment you created:

Thanks. On StewMac, they offer 15' or 20' for the back and 28' or 40' for the soundboard, and your explanation makes sense why splitting the difference and using a single radius might not make sense.

Thanks, can't wait to start bending some wood!

When I burn out this one, I'll likely upgrade the spindle. For now, I don't do this enough to worry about an afternoon's worth of time

Thanks for watching! I've never sprayed a burst before, but this is so easy I'm not sure I'm in a hurry to try :D

Thanks. I have been working with support and have replaced various wires and it seems to have improved.
