Did a bit more on my little Stuart 10V today. One of the next bits i want to do is drill the cylinder, cylinder base and cylinder head. Effectively 5 holed flange, on a 28odd pcd... Ideally, i'd have a little rotary table, or a mill with DRO, but lacking either of them. I have the Myford and drill press, and have a diving head in its box(never been use, and dont know how) Any bright ideas on how I could drill accurately? I could use the base and cap to spot through to drill the cylinder. The usual 2mm clearance on bolt holes wont quite cut the mustard on this job Could I somehow use the dividing head bolted on the drill bed? (table tilts/rotates etc) I did look at some of the budget rotary tables, but not convinced myself to buy one just for this.
