Porting tools

Does anyone have any ideas on what kind of tools to use for porting crankcases and cylinders. I have some old Lambretta casings at home to practice on. Eg Dremel or Die grinder + which type of burrs to use etc.[:drink:] [:drink:] [:drink:] [:shock1:] [:dance3:]

Dremel makes an accessory called a flexi-shaft which makes porting a snap, its basically a spinning cable ( like a speedo cable) inside a flexible shaft (also like a speedo cable) that connects to all the same dremel bits and it’s about 2ft long so it’s very convenient to pull inside a cylinder. also dremel has a high density rubber bit that’s excellent for getting inside of and polishing up those ports.
