Very good video for Goodall guitars - every time I see one of these videos I learn something new. Fascinating approach.
For some reason I can't get the forum Youtube tags to work. If any of you can, please do!

nice video.

interesting take-a-ways:

-tenon-less neck joint. what about shift or finish burrowing?
-perimeter thinning of the top -closed box voicing.

Thanks. It is amazing how we all gravitate to similar techniques for some things and unique for others.

You always learn something from a shop tour.

Goodalls are great guitars. I actually made some very positive changes in my instruments based on examining a Goodall that was owned by a great MN player.

Haven't posted here in a long time and am expanding/cleaning/reorganizing my shop with the hopes of building again and found this video to be very inspiring. Noticed those 2 things as well Arie. Also noticed what seemed like pretty thick tops to start the voicing process?? Could be wrong about that. Again very nice video, thanks for posting that!!

i've had the chance to play and examine about 6~7 or so Goodalls and have also absorbed a fair amount into my stuff as well. specifically on the back plate.

Great video!

Interesting the way he uses a router jig to shape the braces after they're glued to the top.
Also the way they feather the end of the braces with that special machine.

Note the use of CA glue to “harden” the spruce top before cutting the channels for the rosette — an idea I’ve thought of but never tried, for fear of the dreaded CA yellow stain. Wonder what brand/formula they use?

Yeah, I might give that a go too. I think as long as it doesn't hit the end-grain it would be okay. Or maybe they're using medium, thick, or gel?

Also thought that was considered a no-no. Would Shellac serve the same purpose?

The dreaded yellow stain comes from CA wicking into the endgrain of an unsealed rosette channel. It sands off fine from above once it's dry.

Staining must be brand dependent (or in conjunction with particular pieces of wood). I've had CA stain flat grain spruce and also stain maple purfling yellow, to where I didn't want to sand any further. Test, test, test or just avoid using it, which is what I decided to do.

Hmm, that's interesting. I've never met a CA that couldn't be sanded off the top of it didn't wick into endgrain, so maybe being picky about your brand of CA has payoff...

There was much talk about the importance of the finish without mention of what the finish was.

As I recall he said catalyzed urethane in the video. Count me as a fan as well, especially as applied by Tony Ferguson.

A few years back I sealed up the binding on ten scraped instruments with superglue, to find the stains the next day. No endgrain was exposed. Couldn't sand it out. There was a lot of sunbursts that year...

An amazing collection of tools and special jigs. That resaw bandsaw was particularly impressive!

...or very sensibly chose a good CA! What are you using Ed?

Well, it's not sensibility I'll tell you that, but luck of the draw. At Larrivee we used Jet so that's what I used.

Then I used PM Hansen cause that's what they carry at the hobby store.

Now I use GluBoost cause I bought some so there we go.

One thing I know for sure is that I hate CA. But it does do things that nothing else can do so I put up with constantly glueing myself to things and finding CA getting into things it has no business being near...
