Reaming morse taper sockets

[S.D.L.Participant @s-d-l]

On the web go to Cromwell tools and search taper socket cleaner.

One of these with some solvent on should clean it up so that a better inspection can be done, I have an INT30 version for my mill.

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!

Speak to the boiler-smiths at any of the UK heritage railways. They may tell you how it's done and even show you the kit that is used.

Funnily enough I spoke to Tracy Tools on Monday about their MT Drills. These are advertised in their catalogue but not on the internet, hence the phone call. The drills are now out of stock and they have been unable to find another supplier, the drills were described to me as proper taper drills, that is helical like a drill, and not roughing reamers.

I've come across three types of MT reamer (they don't count as drills):

Straight flutes, notched – roughing reamer

Straight flutes – general purpose reamer for cheapskates like me

Single spiral flute – finishing reamer (Probably wehat some people have been calling an MT drill).

I've made new MT0 and Mt1 sockets by step drilling and finishing with a taper reamer, woudln't like to do this in tough steel or at MT2. Go very slow, plenty of cutting fluid and withdraw frequently.

Tip for step drilling – insert a drill into a matching MT socket, now wrap tape around it level with the end of the socket, now get next drill up and repeat until you have a set.

Starting with smallest drill, go in until you are 2 or 3 mm from having the tape level with the end of the blank. Repeat for all drills and the hole is ready for the reamer which will work rapidly at first but slow down as the steps are cut away. If you worked accurately you will have very little cutting to do at full depth.
