Any engineers or frame experts please help

Hello

Right i have a old dirt works monster frame , and it takes those small yellow nylon bushings similar to the old specialized ground control fsr.
These are impossible to replace and B.E.T.D want £75.00 to make a set of 8 new ones , which i think is steep.
Could the frame in anyway be machined so bearings can be pushed in?
Also there are these metal cones which go into the frame above the bottom bracket.
It may cost the same for the work but if i need to replace agian it will only cost a few quid on bearings.
I can take detailed pics and measurments using a vernier caliper.

cheers

Jason

i followed this guide http://forums.mtbr.com/showthread.php?t=226577

i fitted a 2001 enduro seatstay on my 98 ground control so i would have disc mounts

the only difference in the stays was the disc mount and the cartridge bearings

BETD may want £75 for 8 bushes, but how much do they want fot two sets, or 3?

Thanks for the info guys , not sure how much BETD want for a few sets , why do you ask? are you in need of some?

buy in bulk

I would imagine that the thinking there is that although one set at £75 sounds expensive, three sets for £100 seems more reasonable and should see you right for a good few years.

Another think to think about if you can't fit deep groove ball bearings in there is to see if you can get shims or reducers made (perhaps by BETD) to take conventional, commonly available metric bushes.
