I am planning on using dentellones/tentellones on my classical, and wanted to know which way the grain should run.  I was planning on using some brace stock I bought which is not going to work for braces because of the slope and twist in the grain.  Should I rip them at an angle along the grain then cross cut the individual tentellones or cut the slanted cut across the grain and cut the individual ones out with the grain?  Or, does it matter, since the grain will mostly be running at odd angles to the top grain?

I just grab a bunch of kerfed lining strips and cut through the kerfs with a razor saw...voila, quick and easy.

In that case, I guess the grain runs the length of the kerfed lining strips - huh?

Grain direction along the width of the dentellone (or length of lining). I cut mine so the growth ring direction is vertical. Although I've seen on a Hauser build the ring direction horizontal. Both 1/4 sawn.

That's the same as if it were cut off a length of kerfed lining, and will be easier than the other option, since I can rip the length of the brace stock to get the angle in need.  Working with a 2' section will be quicker than working with lots of 4" pieces.

Thanks for the information.

For the Romanillos class we cut them as shown in Marc's first pictogram. Since the largest section of the dentellone is against the side, it make more sense for it to expand and contract in the same relative direction as the top.

Thanks Shawn.  I thought you might chime in.  I appreciate that.

Tentallones drive you crazy while youre trying to stick the little suckers in...no point driving yourself crazy making the things as well.

Absolutely, I buy my Spanish cedar ones by the bag ready cut from Madinter.

I have never made any, but could you not profile several strips and chop them simultaneously with a simple sled on the table saw? That should not take too long.

I rip a few strips, profile a curve on a router table then cut on a table saw with a stopped miter, takes about 30 minutes to have all I need for a few guitars, and at the width I want. The wider they are the fewer to glue. Cutting through pre-kerfed linnings makes for narrow dentellones.

That was my plan too.  My only concern was the grain direction, whether it should be perpendicular to the side grain or parallel to it.  I already wasted one block of this brace stock trying to split it for braces.  I won't make that mistake again, but I figured to save the second one by using it for the tentellones, figuring that the variations in grain wouldn't matter as much in such short pieces.  I figure cutting on my radial arm saw or my chop saw should be pretty quick.  I need to use this wood for something.  Or, I would be glad to trade a box of spruce kindling for a box of tentellones.
