I first saw a Moulthrop mosaic bowl on TV and was interested in how he created it. I know it is small sticks in a “carbon resin” that is turned on the lathe. When I researched turning polyester resin (which may not be the same as what he uses) online the only thing I could find was pen blanks. I saw somewhere that you can have issues with casting resin in larger forms such as what would be needed to create one of these bowls. I was wondering if anyone has done anything like this and how it worked out. I never use my lathe and may never even attempt this project, but it still interests me! Any ideas? This is a link to see what I am talking about. http://www.mintmuseum.org/mason/masonsite/moulthropph.html

I saw a special on PBS about the Moulthrop family, they are all accomplished turners. He took the resin and some small branches about 3” wide and put them into a 5 gallon bucket. Looks like he cut the bucket in half and and then turned the blank. They are vey cool looking. The lathe they use, it quite interesting looking, they even have some sort of home made spinning device to apply the finish. They are making some fine art, and it looks like it has been displayed in prestigious place, and sells for a high premium.

I saw the same thing on TV and know the basics of how he does that. My questions related more to the complications surrounding casting resin in a large mold. I read somewhere that you can have issues with the center not curing properly. The only things I could find about casting resin were in small molds such as pen blanks. Any ideas?
