Question about mounting sprockets
Just wondering what you guys think about this.
Which is the best configuration of grub screws when mounting a sprocket. http://i433.photobucket.com/albums/q...THING00164.jpg http://i433.photobucket.com/albums/q...C/SPROCKET.jpg A http://i433.photobucket.com/albums/q.../SPROCKET2.jpg or....

RE: Question about mounting sprockets
I ordered that stuff in the picture through a local bearing/hydraulics/machinery parts shop.
They had to order it in from Sydney or Brisbane I think. Can't remember how much it was as I got them ages ago, but I think it was around the $120 mark all up, with 3 meters of chain and the 4 sprockets. 10, 20 and 40 tooth sprockets. (#25 chain by the way, same as on pocketbikes and scooters etc) |

DVP i followed the B way on mine.FG uses it too on their wheel squares.Also,make 2 flats,tighten the screws and drill where the mark from the screw is.Drill only 1-1,5mm;)

FG uses it too on their wheel squares Also,make 2 flats The axle is 1/2 inch and the grubs screws 5mm by the way. a key way is the best |
RE: Question about mounting sprockets
DVP i have many friends who own shops with mills,lathes,cncs ets...They all agree that a keyway on a such a small axle is a big no.First of all a keyway is going to weaken the axle and second is too much a pain in the @@s to make the middle point dead on 90 degrees.I don't say it can't be done,everything can...The question is,is it worth it when you can follow a much easier way?
Also,you have to drill the axle on the flat.I'll take a pic of my old one to show you what i mean |

Being in the machine tool field myself,every sprocket we ever did or bought had it like option B;)
