Basically, I am not in the leather business. I am scientist by trade, and projects like leather or guitar building, are a very serious hobby. I do sell some projects, but most of what I make are gifts or fabricating things I use because I like to make stuff.
In the immediate future, I have no need for the bigger machine. However, in the future I can see myself repairing horse blankets and even making a saddle or two. A lesson I learned wood working is that if I buy a machine bigger than I think I need, I can find a use for the expanded capacity. The more I think out loud, the more I am leaning towards the big machine.
