Hi. All. My little Demon is coming on, but I've now reached the camshaft, something I've been putting off for a while. As I only have a Myford Super7 using the turning fixture described might be a bit of an ask. I've fabricated four throw camshafts before but the angular positions of the individual cam lobes was always supplied. I can't see any way of establishing the individual cam lobe positions from the spread sheet with the plans and as maths was never my strong point I would be grateful if there's a member who can check my calculations for the angular positions each lobe. I've taken Exhaust #1 as zero (360 degrees) with #1 being the first lobe to load and bond, the angular positions follow in cylinder order rather that firing order. Firing order: 1 8 4 3 6 5 7 2 Lobe separation of exh. and inlet is 110 degrees. #1 ex 0 inlet 250. #2 ex 240 in 130. #3 ex 60 in 310. #4 ex 280 in 170. #5 ex 340 in 210. #6 ex 200 in 90. #7 ex 100 in 350. #8 ex 240 in 130. Thanks. Mick.
