I guess #3 and #4 (just cuz I choose the middle ones), but it could be any one - David your work is absolutely superb!!
Thank you Mamu, as you probably guessed, one or two of those just may be yours
Going back to my earlier post about the quality of machining; what i am doing isn't anything that any other competent machinist can't do if they simply take the time to do it right (assuming they also have the right tools for the job). Machining, esp. on a non cnc lathes and mills, is all about the operator and the care, pride and time he/she puts into their work.
