sv cam followers and big4 girder info please

alex here in brisbane australia.

I would like some help with my norton ES2 project.Loosely 39 Based.

firstly... the sv motor 1935? has been converted to late 40"s OHV and uses the sv cam followers of pre 37 that have the hole in the top surface for the pushrod to sit and the bottom radiused surface runs on the cam. It is exhaust gear driven motor.The followers i require are the shorter type being 2 inches from centre of pushrod to centre of pivot shaft.I have a longer set that are about 4.5mm different.I dont know if there ever was 2 different lengths of this type of follower or the OHV conversion resulted in this and custom followers were made for this motor that the previous owner kept. Anyway i require a set of the 2 inch centres.

second ...I have a plunger frame and Big4 girder front end.162mm inside fork... I would like a drawing of the big4 front axle with spacers and dimensions and axle nuts to suit as they are larger than the 16H nuts. any UK suppliers of an axle and nuts .. as i cant seem to locate any in Aust.

A drawing or pic showing the location of the locking nuts, which side of the hub? Using a later ES2 roadholder hub with LHS 7 inch brake plate.

If i use a larger diameter axle as in the later tele forks to suit the bearings and Brake plate with appropriate spacers what is the point of the older locking nuts and the sleeve space between the wheel bearings.Wouldnt the bearings running on the axle be a better way than on a bush and then the axle ?

I realise i am using parts from different models but that is what i can find at the time of the build.

any help will be greatly appreciated.

regards alex
