(1/4) > >>

energiza:
Right brought 2 nos acs boa.s from a fello rad member.and they are both large thread rears.so had a brain wave.tryed tap n di.ng the thread down to 6mm.not good.these are some proper solid threads on these boa.s     :-\  so another brainwave come to my head.took me 30 mins :) and a presto it only bloody worked.ive done one already.so ill be taking some step by step pics of the next one i convert today.so hopefully it will help out u fella members who have them thick arsed thread ones layin about collecting dust  :smitten:

bof:
I reckon a 10mm drill would be the easiest way . Do you need pictures ?

+ 1 and your never going to cut that thread smaller, change the spindles its a peace of piss just dont loose all the bearings  :daumenhoch:

energiza:
 :D i did take one apart originaly and it took me about 2hrs to but all them lil bars##rd bearing back in,so gave up on that idea..these are to use on rider.solid as a rock

1st pic before and after

1st tools required lol

use them saws

wheres that chunky thread gone

energiza:
part2 file down so level with spring holder

then 3mm drillbit to start you off

working drill sizes up from 3mm/4mm/5mm then 6mm

not the straightest of 6mm holes,but a it works

get your 6mm thread,wak on some super strenght chemical metal and put in 6mm hole.leave to dry for a day and wooo a 6mm boa is born again lol
