now that he bondo is hardend its time to brake off the plaster water helps a bit but it only takes a minute to scrap it off with a knife and then all you need to do is trim up the sides on it and your done

I have been making small carvings out of vegetable ivory nuts. The two problems they have, besides being only about plum size, is that they have a dime sized void in the center, and since they are nuts after all, they have an empbryonic palm tree at one end, that falls out when they dry out, and leave a hole about 3 milimeters wide by 3 milimeters deep. I wonder if bondo would fill that hole without looking out of place. The ivory nuts are usually a pale yellow-white.
With the Tagua nuts I think you'd be better off starting with a white casting resin like Snap-On and adding a little yellow pigment to match the cream of the nut than using Bondo.

Perhaps I should ask the people in the Woodcraft store about how to fix that hole.

Hi, I've done something similar a few times, try mixing your "Bondo" etc 50/50 with polyester (fiberglass) resin, It pours easier and the stuff I had made the castings incredibly tough! You can also get other types of body filler in various shades including white. I colour mine with bottled pigments for fiberglass. Keep experimenting and have fun! Hope this helps.

Hi Brandon. Your instructibles are getting better. I have used bondo to copy small pieces of wood trim.

Nice work. Simple and to the point. Is this a common method, as I have not read of it before?

Nicely done. Some spelling errors, but the instrucable is clear and easy to understand
I concur. ;)
