Applying the right finish to a wooden knob? Answered

I was wondering what finish i could put on a shift knob i made out of purple heart. It is something that i will be touching every day, and it isn't light use. At first i was thinking linseed oil, since i heard people use it on gun stocks and stuff that people like to keep natural looking. But my father suggested some sort of wax instead of an oil. He's got some goddards cabinet wax i could try. Also i sanded it smooth and went to 800 grit sandpaper so it is very smooth. I was even wondering if it is possible that it is so smooth that it doesn't accept a finish well.

Any and all advice is welcome,

I just read several articles about wood color and trying to preserve the color of various woods. Purple heart is one that fades to gray/black fairly quickly. It needs a UV coating of some kind for it to keep its color for even a little while.

And, no matter how smooth you sand it the grain will get raised by any moisture and that includes sweaty hands. So you need to have some kind of sealer that protects from moisture. I used floor finish for several of my projects and it has held up pretty good so far. You might even think about getting an epoxy base finish. That might help with durability issues.

I noticed that when i turn purple heart on a lathe it leaves it a light brown, but after a couple days of sitting on a shelf it turns back to a deep purple. I'm not sure what causes this.

Probably from oxidation, Just seal it with some simple varnish, maybe with a good UV blocker like Vyger said. Maybe wait untill the wood changes back to the color you want?

btw thats some really cool wood! Never seen it before; thanks for the share :)

add a bit of vaseline to your knob and keep rubbing untill you feel like its finished :P

other than that, just use beeswax polish. it can be found in loads of shops.

Wax. any varnish finish will just rub off ad need replacing regularly.

wooden pens are finished in superglue. gives a hard wearing shily finish.
