Dead simple. Hone the HSS cutter and dress the second leg of the third shaft down to the finished sizes of Half an inch for the journal and .375" for the shaft. Tomorrow I am ready to start turning the fourth and last shaft but at the moment I am after my breakfast.

Before I started on the last shaft I addressed something that has been nagging me for a while. Most of the indexable tools I use are from Banggood and they don't last long when set too on serious muck shifting. So I went into my indexable store and got out two tools I used to use with my large lathe 30 years ago. They are commercial grade and I have plenty of tips for them. I swapped one for the boring bar in my tool holders and fitted the larger one in the original tool post that comes as standard with the lathe. I set up the last blank and started the succession of 40 thou cuts that will get me there with no dramas. My picture is of where I knocked off after an hour of good work. Now for breakfast!

Another advantage of these commercial cutters is that the triangular indexable cutter has 6 cutting aspects so I treated myself this morning to a new one and then set to to get more metal out of this leg. I got it down to within striking distance of the half inch journal I am chasing, finish turned the web of the shaft and then took a light cut across the edges of the webs. The work is too hot for accurate measurement so I knocked off there and will finish turn this leg tomorrow. Right now I am after my breakfast.

This morning I did the final turning to size and initial polishing of the first leg of the fourth shaft. Once that was done I turned my attention to a mare accurate setting of the big indexed cutter, it's cutting slightly above centre and to cure it I have to take some off the bottom face of the toolholder and it's hardened.... I worried at it with the grinding wheel and a very sharp file and got it to a far better place. I will see a difference when I chop out the metal for the final leg of these four shafts. Now I want my breakfast after an hour and a half in the shed.

I've been looking for this cut for a while..... The last roughing cut on the last leg of the last shaft.... The trial of my patience is almost over. The work is too hot for accurate finishing but that's no problem, I would be leaving that until tomorrow anyway. The pressing matter now is breakfast.

Here we are, pure masochism. Four shafts for Stuart No. 9 engines, chopped out of solid and needing only finish turning to suit their own engines. That's five shafts in stock, I doubt if I will build another five engines! Now I can give them a polish and put them on the kitchen table for eye candy. In the shed I am looking at a massive clean-up and then unboxing the next set of castings which is sat here in the kitchen waiting for me... But you know what I want now.....
