Hi .. Well I was into it again...had to cut the grooves for the throttle and clutch pivots into the lower side of the handlebars..Used an end mill to do this..machined a pair sleeves for them in the lathe...ed them in and will clean them up tommorow...Have machined the slots in the twist grips..these will keep the tubes in place on the handle bars and restrict the twist to 90deg rotation...these will be held in place with a 5mm role pin....I dont know whether I will use rubber grips or bind it with original cotton tape...this was done in the milling machine with a rotary table with a chuck fitted to it...the rotary table is mounted vertical on the main mill table...as inferred the rotary table has a crank worm drive on it and it rotates 360 degres...it also has a separate part to hold the work piece called a stock...need this to hold work piece in a horizontal position....with the cutting tool in a fixed position..the work piece can be rotated and cut the slot...the easy way out is just cut it with the 4" grinder ...this has got to be a bit more precision as I dont want the twist grip binding or even jambing.....DD
