Hello Again,
Interesting how advice varies from poster to poster! With regard to the 2MT drill that I was referring to. It was definitely intended to drill out a Morse taper. It definitely wasn't a straight drill with a 2MT on he mounting end! I am glad that someone else has come across them, otherwise I would be doubting my sanity!
From what little has been said, it would appear to be easier to drill and then bore out the taper. Thanks for the setting up tip that was given a few replies back, nice and simple, which is what I like!
Before my muscle wasting illness, I helped refurbish a Norwegian loco boiler. New plates were welded in where corrosion had set in and a HUGE Russian radial drill was used to drill out the stay holes. I saw a friend of mine ream out a very large taper which was a to be used for a washout plug (subsequently threaded). A very large and strong man to boot. Using a taper reamer he produced a very good taper and a pile of swarf on the floor! So tapers can be hand reamed, providing you are strong enough! However I would now have trouble picking up the reamer, let alone using it!
Thanks everyone, a very useful exchange and plenty of info
Regards,
Andrew.
P.S. Don't ask me how the washout hole was threaded, I didn't see that bit! I was too busy pushing red hot rivets into the flanges and a holding them there while a pneumatic riveter did the job from inside the shell! I am still deaf from doing it!
