No worry. Was my second attempt. Deans gave us the inspiration and the next was I need a very robust and steady RT to mill the big/small ends of con-rods. The face plate and top cover had to lapped to give 100% contact to elominate vibration and rocking and chattering. A SDP precision worm and wheel must mesh real close to prevent rotary backlash when milling job big end and small end con-rod profiles. The collar nut below spindle must adjusted and locked to eliminate chatter.
Dean gave step by work instructions which is very helpful. W/o which,Gus would have given up. For some reasons,he left out graduation of hand wheel and table and the letter stamping. The RT took some time to complete and troubleshoot. Cams were also cut with RT with minute angular and quill feed.
Just bought a ''Made In India'' 80mm three jaw chuck. Not as cheap & nasty as the M.I.C. chucks and quality wise was good. Planning to build another RT cum divider with indexing plate to cut 14 spur gears for the Howell V-2 Engine timing gears. Paul Swift is mailing over a gear hob.
