How can I make some 1/8 splines that need to be black? They are for splines in the ends of boxes. They are 1/8 thick and need to be black all the way thru as they get sanded. Thanks for any help.

Black wood? Walnut is dark, but wenge or ebony are usually black enough.

Black ink works well too just rub it in and let it dry.

It depends on a number of things. I looked at the clock project you made and it is beyond great.

With the high quality of such projects, I would spend the money for ebony. It is the best black wood but I find them to be a little brittle at times.

I have bought ebony on eBay where you can see the picture of the exact piece you are getting. It is not cheap but looks great. I use small pieces for Intarsia for eyes and claws.

I bought a piece of black palm to turn. Given the necessity for stabilizing the grain, and the splinters it throws off like a porcupine, I’m going to burn that piece of wood. Expensive smoke, but that’s the way it goes, sometimes.

I use ebony for those sorts of things. Yes, it is expensive, but in the small touches that I use, it isn’t all that bad.

Ebony or wenge are going to be your best bets. Generally when making splines you make them oversize then trim or sand them flush after glue up. Dye is unlikely to penetrate all the way through the spline and when you trim it back the spline may only be partially dyed. Then the fix will get really complicated because they are glued in place. Make life simple, use some dark wood.

I use turning stock from Woodcraft. They always have some ebony. Bandsaw off a shade over an 1/8 and sand to fit.

If you are using a low tannin wood for the box you may be able to use a high tannin wood like walnut or oak for the splines and ebonize them after sanding with a ferrous ion solution. The solution will turn the high tannin wood black and leave the low tannin wood substantially unchanged.
I would experiment a bit but it should be doable. Something like maple and walnut should work.
