Getting started with the basic tools
First I like using the chuck, the cheapest one is the Penn State Baracuda, this is the best deal right now.
Or if you want a smaller chuck that would work for boxes and small things.
Next tools, I like the mini set for turning small things.
And possibly some bigger tools.
Then a sharpening system the One Way Wolverine, or just a little cheaper but maybe not as solid.
A slow speed 8" grinder.
Past that you will find many other things you may need as you get farther into it.
