I think you have to start with a lathe but if, like me, you are in the business of making a working model rather than an exhibition model, then I would plug the early acquisition of a linisher. I converted one end of my grinder into one many years ago and wished I had done it many years earlier. What a timesaver it has turned out to be. I use good quality belts and the speed with which I can round the end of rods or fettle castings is amazing - mind you, you do need good gauntlets to hand the work - it gets very hot! It's just essential to emphasise the need to clean the dust away after any operation involving aluminium. Dennis Rayner MODEL ENGINEERING DISCUSSION LIST.
