I do have some experience with lots of machines. I worked in a shop where they made several types of engines. Aircraft, Army Tank engines and numerous 4 & 6 & 8 cylinder engines. I have run mills, multiple drills, lathes, and much more. You got to understand though...most of this equipment was set up for running. I more or less just changed tooling. Except for when I worked in experimental. There I got to do some basic set-ups on my own. The small lathes like a 9x20 are different to set up than their bigger brothers. That is why I ask certain questions for the smaller machines. It is guys like RCIGN1 that really knows his stuff on setting up about anything you would need to do with the machining /conversion of the RC engines we admire. And there are other guys like REV Av8tor and a few others that do a fine job also. I hope you all understand what a privilege it is to ask and get very good replies back when needed. I hope you all continue to share your knowledge and experience. To me this RCU would not be much at all except for the great guys that help and share. I am not good at typing....it took me way to long to type this short post. Take Care and Best Regards to ALL! Capt,n
