[QUOTE="royrobertson, post: 99393, member: 2486"] Hi Vic, I was going to use the same milling process for my main-shafts until I found the Spline cutter. How do you do the mating internal splines? Wire eroding? The originals would have been broached I think. Over here Bob Newby supplies various belt pulley sizes to fit the standard Vincent main-shaft and the fit is perfect. At the same second-hand tool shop (still going strong) I found over the years, my little bench cylindrical grinder, a small indexing rotary table, a mill/drill and a nine sixteenth of an inch LH x 20 tap which is the thread in BSA Gold Star (and maybe other) fork legs. Your workshop looks really super and makes mine look what it is, a garage crammed with small old second machines. However with my toolmaker training I get by, it just takes longer. There was a reason why silver plated cages on needle roller bearings was good, I just don't remember what it is. Maybe someone knows. Running on R40 oil they have certainly done well with just the Vincent Twin Start oil pump to push the oil around. Like you I don't stick to Imperial sizes where Metric suits the application better. Some of the titanium nuts I have made have imperial threads but smaller metric hexagons. A weight saving exercise. All the crankcase and cylinder studs are also titanium, as are many other parts. Loved the Photos! Cheers Roy [/QUOTE]
