[QUOTE="Jez Nemeth, post: 108061, member: 3871"] Thought of that one Bernd -but good point ..a mate mentioned to me there might not be enough 'pull', checked it against a commando one -bit of luck, had a Commando lever in place! Might it be a Norton owner's mod? (even thought about lengthening it a bit too, cut, weld, temper...). Think the Clutch should be ok, its just that cush system, or rather lack of one which is having me scratch the rain detector. Can't think of what I've got close to 25 tons hanging round the house to do what you've done there :) . Looked at Yammies, Hondas and Suzie clutches, there seemed some possibilities -Ben and Steve over at Conways/Godden do a loverly one with their Honda kit. Trying to keep standard case if possible, if everything works out it should all fit, otherwise its an 8mm thick 6082 'gasket' Vibrac mentioned. Ordered a mild steel pulley for 32mm Belt (it was a choice between 25,27,32), AT10mm pitch, 37mm (Outer flange to Flange width) - 93mm OD (bonus meant I could go wider with belt, stated 96mm on web, but actually 93mm?), and has a boss of 50mm OD -13mm depth that I can turn down. Be here in 10 days. Only real issue is if my old 1920's Drummond lathe will cope with turning down the bits, or do it at work, when I have the time... Question though, did you find it harsh in use when you had the belt on it? Don't remember Commando Clutches being discussed as exemplary examples of clutch technology, but they can be refined...that Comet Mongrel post is good for that.. Commando Lever + Alloy Boss, be fettled drilled and tapped later...Friday night, my wheelie bin goes out more than I do... [ATTACH type="full" alt="27413"]27413[/ATTACH] [/QUOTE]
