Belt Advice on Construction

[Titus Marius Secundus]

I am using 10" :S anything thicker, maybe not 15, but would be terribly straining. I anneal very well over gas stove to a nice red... shall see. If I use a larger blank...might solve but like I said then you have to cut or saw past the rolled edges, and risk having to open them or round them our again. All takes time!
