  1. Thanks for the advice Tom, I tracked down a new front bearing and it is running as sweet as a nut now. Apparently Royal is a common make for dental technicians although they don't seem to have a web presence. It cost me a tenner and was easy to replace. for anyone in the UK with one I got it from a company called Skillbond, they are also sending me details of their range of burs which sound interesting. Dental technicians seem to use bigger stuff than dentists. regards Tim.
  2. Hi, I have an ex dental Micromotor, a Royal Hand engine C-33 . I got it second hand a few years ago and it has been very useful for delicate wax carving and also a bit of silverwork. It is starting to get hot at the front end,ie too hot to hold in the end. Can(or should) I oil it , or are its bearings going. I don't put a lot of pressure on it but a do use it for prolonged periods, say 1/2 -3/4 of an hour at a time. is this too long to use one? I wouldn't be without one now, especially since I made myself what I am told is a 'Knuckleduster' see below I didn't invent it but I can't find the source at the moment. It does stop your hand aching though. Anyone help?, regards Tim.
