Modeler12 Posted March 19, 2014 Share #1 Posted March 19, 2014 For my next project I need 16 guns (6 pounders). I am using the drawing published by the late Harold Hahn who came up with the formulas and dimensions for a variety of guns used by the British. The first drawing shows how he arrived at the various dimensions. It involves the scale you are working to and the caliber of the gun. The sides of the carriage are obviously the most complicated. Using my new mini mill and a piece of pear wood, I proceeded as shown in the pictures that follow. I used four different bits, including the diamond coated V. I do not have a rounded bit with this small a diameter and will have to file the round groove by hand after the 'log' is slices. I need at least 32 of those pieces at a thickness of 0.051 inches. To cut the last step I decided I was too close to the vise and turned the part around. All cuts were made at about 5000 rpm. I think I would not have been able to do this without the mini mill. For me this has been a good investment thus far. ianmajor, Chuck Seiler, aviaamator and 4 others 7 Quote Link to comment Share on other sites More sharing options...
