That's a lot of guitar tops, kinda spooky actually...

Good videos!

One of the things I learned from those Michael Thames videos is that with PVA glue you can use the 'heat creep' property to get things to 'adjust'- either in the oven or with a steam iron.

Anybody know what kind of (band) saw blade to use to slice off those rosette rings without turning 75% of your work into sawdust???

Enjoyed the videos a great deal. Thanks.

I jokingly refer to this video as "The Titebond Informercial"!!!

It is an excellent tutorial. Although I use a totally different method (my rosette are assembled in the soundboard), there is still a lot of very valuable information that is usable in just about any method.

I did cringe however, when he was running those mosaic logs through the band saw with his fingertips. That is a big no-no. You must use push sticks to do that safely and accurately.

Very nice video. Thanks much,

If anyone has pics of your methods for slicing rosettes from an assembly this large (jigs, fixtures, sleds, etc.) please post them. I am very curious about that. And YES, push sticks should be used
for safety in a situation like this. He let his fingers get perilously close to the "meat saw."

Thin kerf blade. I can't remember the exact gauge but it's something like 0.4 mm. The next gauge up is around 0.6 mm and the 'standard' blade around 0.75mm. The thin kerf is the type normally used on very small hobby bandsaws. Suppliers (at least in my case) sometimes refuse to make such a thin blade for the larger bandsaws. They fear a return after it has snapped after 5 minutes use. The couple of blades that I've had lasted and left a very smooth cut (14 tpi) - at least in bandsaw terms. I don't have a table saw so I also use the blade for making up herringbone.
I normally build my rosettes directly into the soundboard. The only time I've sliced rosettes on a bandsaw was when I made a multiple closed ring rosette. At around 1 cm it was probably half the width of the Thames rosette shown in the video. I did not use any special jig, just a push stick to keep it against the side fence whilst very slowly spinning it with the other hand. Let's just say that I took it real easy. I was also probably taking a risk because cutting round objects without some type of cradle is a bit of a no no on bandsaws.
