Hi & welcome Roan - where in SA are you based?
Can you show us pics your 'wheel? There are a lot of Saffers on here, but it would be great to see more posting.
I absolutely concur with what David wrote. I'd go further and say before you buy any other tools, you should order his DVD. Hands-down it is still the best money I ever spent on metal shaping.........and I have spent a LOT
@Cobus, if you are so close to me feel free to get in touch and come past my shop. I'm on Blaauwklippen Road.
