I am building a sliding barn door for my study. I am making it out of walnut. But it has a very beautiful void in it. It goes nearly through the piece of wood but has lots of valleys and spurs in it (to borrow from the geographic realm).

I was going to use it as the top part of the bottom rail, (i will have to glue up a couple of boards to give me the width i need) rather then the stile. It wont be as obvious there but some people may still see it.

why do people usually go with the black tinted epoxy rather then clear. Is it because most people dont want the focus to be this void and rather let the piece speak for itself?

Atilla, I can’t speak for most people, but when I did this walnut project I wanted to minimize the visual effect of the voids. I have seen granite counter tops filled with clear(ish) epoxy and were I do do a maple slab, I would probably use clear epoxy. However, beauty is in the eye and do what your client (you) prefers. FWIW

You can color epoxy whatever you want, and can use all sorts of stuff to do it. Neat epoxy (epoxy without any other additives) naturally is slightly amber (from the hardener), and it gets more so with age – but you can get hardeners that will allow it to cure clear (eg: West System 207 Special Clear Hardener). With the right color mix, you can match an existing wood to have it blend in, or choose a really contrasting color to make it stand out. Black is popular because it generally offers the most contrast, but I really like reds and browns as well. You can also embed stuff into it for an even more varied look (precious stones, wood chips/slices, metal shavings, etc…). For example, turquoise is pretty popular, and looks spectacular against darker wood.

In the end – it’s your wood, your choice… do whatever YOU think will look best :)

Thanks for your input. I am going to give it a try. I am going to put the largest void as the top board in my doors bottom rail. If, after i add the epoxy, i don’t like it i can always cut out that section i suspect.

I will include some photos later.

Just for reference, here is a turning I did, after filling it with two to one epoxy. People who see it assume the filled void is part of the natural grain design.

I, also, have used embossing powders mixed with oyster shells, coffee grinds, saw dust and so on to create effects, or to minimize the obviousness of the void.
