Tool For Copying Curves?

What is the name of the tool use to copy curves? The manufacturer? I am looking for the one that looks like a row of pins or rods that you push against the curve your trying to duplicate.

Hey Dan.
Go to www.harborfreight.com and do a search for contour guage.
They list a couple. One is $7.99, the other is $4.99.
Check in your area, they may have a retail outlet close to you.

I think I’ve also seen them in hardware stores like Lowes or Home Depot.

I bought mine at Home Depot. The brand name is General.[;)]

Thanks guys. I picked up one of each.
