About concrete countertops-I am making a bathroom sink and need to buy an oval plywood form for in the middle?

Question:Where can I find this on the internet?? Also, where can I buy brass inlays to put inside the concrete??? I've looked all over!

Answers:
You are probably going to have to make your form. There are several methods to do this.
You can use styrofoam (which you can purchase in up to 2 inch thick panels), layer it as you need to, in order to match the thickness of the concrete.
Another option is to make your oval out of a few layers of plywood, if youre not going to have a very thick countertop.
Plywood can also be bent into curves by scoring it every 1/2" to 3/4". Score thru the plywood layers on a table saw, all the way thru the first few layers... you want to leave about a layer and half intact.
"Bendy" plywood is a product made specifically for curves. Ive used a lot of this product commercially, and can say that Ive always been happy with the results. One layer of "bendy" plywood is pretty flexible, if you glue 2 layers together, you can make a stiffer curve. Just do an online search for "Bendy Plywood", and you should find it.

As for the brass inlays, do a search for "Decorative Brass", and you will find many places that sell what you are looking for.
