That's the site I mainly use but what about something where you can choose 2 or more different size kanthal wire. I.E. On being 26 gauge and one being 24 and twisting them together or like on a Clapton where you wrap around a straight piece of kanthal
The problem with steam is it only lets you choose 2 of the same gauge but I need something that say if I wanted to do a twisted with 24 and 26 and know how many wraps to get my targeted ohm. If I knew how to make an app that could do it I would but that would be a great idea for someone that knows how to make an app or calculate it
