You are welcome. If you can benefit from our mistakes it will save you loads of time and money. I'm not decrying the belt idea, I don't know enough about belts at this length to make an informed comment but the basic machine you have there would be easy to convert to R&P if the belts prove troublesome and you might have earned enough by then to modify. The main thing is go for it, there are so many knowledgeable guys on this forum who've built machines and made all the mistakes, they will keep you straight. Above all, don't be afraid to ask all the questions you want even if they seem daft because they are the ones that can be showstoppers.

Jeff.
