Topic tags/keywords: question

Quick question… in the picture below you’ll see that I drilled out a declivity and glued in a half a black walnut shell (what I like to think of as a little owl face) on the front of this little box.

I was considering pouring polyurethane into the walnut and around it… so filling the spaces with it.

How long might that take to cure? Do you see any issues with this approach?

If by “polyurethane” you mean an oil based varnish, I think you’ll be in trouble. Varnish takes a long time to sure when put in thin coats on a project, having some that thick might make it cure slower than concrete. Then there’s the possibility of a lack of clarity. Since it has some amber to it, it may be so dark when put on that thick you can’t see through it. A clear epoxy would be a much better choice.

I’m very glad I asked… want to be able to see the little owl!

Where would you purchase epoxy?

Sorry, I’m very new!

Just search for “pouring epoxy”, Amazon has it along with most of the vendors that cater to woodworkers and woodturners.

Or you can also search “casting epoxies”

I think you will get some recommendations for the West Systems Epoxy. It seems to be one of the more popular epoxies mentioned.

I have used a lessor epoxy, I can’t compare it to the WS, or say it is as good, but it was cheap, came in 8oz bottles, and was easy to use. It’s crystal clear and has held up for years.
It’ also available at stores like Michaels, Dick Blick, Amazon, and most arts and crafts stores have it.

Here is the one project I used it on. (The oval and cross in the center is about 1/4” deep)

I don’t think so, I’ve never bought it there. There are lots of places to get it online, including Amazon.

Look for casting resin at your local craft supply store. Or, you can order it from places like Amazon. It requires mixing a polyester resin and a catalyst that come together in a kit. it will cure when poured to most any thickness and will be virtually clear.
