On another forum ,nowdays never a week goes by without some newbie busting the feed gearbox on a Bantam or Student by useing a bed stop ........clever operators like.....the saddle just pushed one stop along,so I used two...... and ..........my one screw bedstop slipped ,so I altered it to three screws........and now the gears are busted.....Simple fact is there are no spare feed gears anywhere ,unless you are prepared to pay several thousand dollars to have them made.....So ,dont use a bed stop and dont wreck your lathe.
