Just made one for £3 from a threaded bolt 4 washers (2 big 2 bearing sized) and 2 nuts The bearing holders alone cost 6 pound odd so how did you make it for 6 lol?

Because I only payed for the bearing holders, everything else I acquired from work when they accidentally fell in my bag ;)

Ok next question did your bearings just pop out are was a drift employed to coax them out ?
I would have thought it was obvious you'd have to use force to remove the bearings. They're pressed in so they'll need the opposite force to come out. A hammer and a length of bar is one way, a tool (Park BBT-30.3 for example) is probably safer but depends how rough you plan to be with the length of bar :smile: Check out the link to watch Park's tool in action and decide if you can get away without it or not. Personally I'd look for some form of removal widget that is shaped for the bearings rather than risking damage.

Not always force my friend depends if loctited in or not and yes I know you can smack them out but I wondered if the OP had also made up a tool for that as well. Remember trying to remove bearings from a Miche hub and it was a PITA to the point that I will never by hubs like those again! On the other hand another hub which took 6000RS bearings was a peice of p1ss, just light tapping and they popped out nae bother.

Thats exactly what I use.....except the bearing holders. Threaded bar, washers and nuts thats all I use. I didn't go for bearing holders just a few washers to do it for me. A drift is the only way to get them out...use a socket piece of wood etc etc there's no other way really at least not for the first bearing. Nice job op....hope you don't get caught stealing from work for a few quid your savings could turn into a really expensive bearing press :smile:
