Re: Engineer/machining services in Bristol
Has the easy out wedged in the stud or have you got that out?
If it is still in then you will probably have to get an engineer to get it out. If you can get the extractor out, try drilling the hole with progressivly bigger drills untill the edge of the hole breakes through side of the thread. in some casses the drill will grab onto the stud and release it, but not often. once you can see the thread down the side of the hole, you may be able to pick the other threads out whith something small and sharp (scriber/small screwdriver) then its a case of running a tap down the threads to clean up any damage, be careful to keep the tap square and not to cross thread the hole. max hole dia for M6 stud is 5mm max hole dia for M8 stud is 6.8mm max hole dia for M10 stud is 8.5mm these are for standard coarse pitch threads When drilling studs, if possible grind the end flat. always spend a great deal of time to center punch in the center of the stud, it makes things alot easier, and try to drill down the center. If all of this still does not work. the next step is to fit a thread insert into the hole, this involes drilling the hole bigger, tapping new threads in the hole with a special tap and screwing in what appears to be a spring that brings the threads back to the correct size. this method can produce stronger threads that the originals. If in ANY doubt, contact a local engineering company, dont forget, if it goes wrong it could get alot more expensive |
