Something entirely different this morning. I have passed the problem of the valve face on the Stuart engine of to Ashley and spent over £600 out of the burial fund on another set of castings. So I felt free to move on to a current problem. This is that I noticed a while since that the ceramic insert in the door of my Morso stove had fallen out. This was due to the ceramic having cracked across the bottom two corners. So I set to to cure this. The screw thread on the adjustable vent on the door was terribly stiff so I took that off and attacked the screw threads on the two clips that hold the ceramic and the baffle on the inside of the door as well as the vent. That took up an hour and I have ended up with the bottom clips soaking in penetrating oil to see if I can free them. If I can't do that easily I shall leave them alone and just use them as fixtures to loosely retain the ceramic, it was the tightening of the grip on the corners due to corrosion that caused the problem in the first place. I have a new ceramic and packing and one way or another I shall finish this tomorrow.shall

Today I started the muck-shifting job of finishing turning the crank shaft. It's not easy removing heavy cuts from stock with a light lathe like the Harrison. You have to do it slowly and with care always remembering that the drive is being transmitted through the weak point you have introduced into the stock. I shall turn the shaft round tomorrow and hold it differently but for today I was quite satisfied with what I have done. All the swarf is out and in the bin as well.

Creeping up on the final dimensions of the crankshaft and finish, I have it very close after this morning but it's too hot to measure accurately for finished size. I have cleaned my chips up and put them in the bin.

Only one image this morning. I have spent an hour and a quarter finishing the crankshaft, doing the final turning to size and finishing the surfaces. It is now ready to fit to the engine. I can forget it and get on with engine building.

This morning I finished turning the flywheel to size (But not polishing it, that comes later....) I broke all the edges, bored it for the crankshaft and put a witness mark on to remind me which end is which. Then I cleaned Mrs Harrison and put the inside jaws back on the 3 jaw chuck.
That done I went for early doors shopping and that is all put away. Now for Breakfast.....

Dead simple this morning. Using the grinding wheel to clean the excess flash off the castings. Rough but a great improvement. Ready for accurate machining.

I did some very careful measuring and then some even more careful setting up in the vertical mill. My task is to reduce the length of the cylinder to 2 1/8" and cutting the faces dead square with the valve face. I did an hour of careful milling and while I can't claim the cuts are dead accurate, they are as good as can be expected under the circumstances and perfectly acceptable for the job in hand. I am ready to set the cylinder up and bore it now......

Today I had to do some wood bothering to make a plug for the cylinder bore. I've done that, cleaned up after myself, installed the plug and done some very careful measuring. I have a centre and have installed the cylinder ready for boring tomorrow, it is set up on centre. No rush with any of this, I need it to be accurate.

Boring the cylinder. Quietly away and a very good result, within a thou of all my measurements which isn't bad for an Old Fart like me! I am very pleased and have tidied the mill up. I shall sharpen the cutter tomorrow morning.

I finished milling the steam chest casting this morning, marked it and its lid with witness marks and had a chip chase. Tomorrow we move forward into the bed castings.
