Drum Drilling

JeffTheMarine said

I have heard of alot of people doing this and no one here has any advice o. It at all? Also I have seen people take small bolt 4 piston disk brakes and drill them for large bolt. Actually a guy at the spring fling in van nuys had them for sale. Stupid me though I didn't think to ask where he got it done and now I am stuck calling machine shops and having people tell me they have no idea what I am talking about. So done has got to have more Information

Moser used to offer redrilling for the KH hubs but due to low demand for the service they replaced the machinery used for it with a more profitable piece. In order to correctly redrill the KH hubs for 4.5", material must be added to the back of the hub between the existing studs. The hub then needs to be machined smooth and finally redrilled for the new studs. It`s definitely not a job for a novice. I tried to have one done by a local machine shop and they failed quite miserably. I would recommend finding somebody that has experience with doing the job before handing over a rare KH hub.
