dabomb Posted February 10, 2008 Report Share Posted February 10, 2008 The best way is to use helicoils.You drill the hole out to a given size,tap the hole,then screw a special wire insert into it,which contains the original thread size.Its a simple job if you are handy.Go to an engineers merchants,explain to them what you have done,they should be able to help.Not sure how much a kit would cost,but it wouldnt be that expensive. Failing that,you could drill the holes out in the hub and tap them the next size up,but every time you put a new sprocket on you would have to drill the holes out(in the sprocket)to fit the larger bolts.

kevhenson Posted February 11, 2008 Author Report Share Posted February 11, 2008 (edited) Weld the hole up and re drill it! bout 5 min with a tig! now i like that idea just need someone near me now who can weld thanks tried the local metalworkers and they wont weld it cos the wall section is to thin for the depth of weld... worth a try tho Edited February 12, 2008 by kevhenson Quote Link to comment Share on other sites More sharing options...
