Some correspondence from past Chairman Brad Wallace-Bradley led to some concern about a photo I had shown in the previous report of the lower end of the stone spindle, where it runs on the dome washer. This small area supports the full weight of the stone spindle, runner stone, upright shaft and lantern pinion. The photo showed a piece broken away from the periphery which was not recorded the last time the spindle was dismantled for inspection.

1st August 2015. Mostert's Mill. Sickles into Harps.

We all know the Biblical expression 'Swords into Ploughshares'; today we ground Sickles into Harps! But we did plenty more besides.
Last time we were trying to raise the part of the Bedstone nearest Cape Town with various levers, but the curb was holding it back. Today I brought a 'koevoet' made by a Railwayman and a few steel plates to lever the bedstone upwards. It still was being stubborn until, while I levered the stone upwards, Paul gave the curb a good smack downwards with a 4lb hammer, with a wooden block in between, of course.

The brake wheel and lantern pinion mesh well now, so after one or two Milling Days to keep up interest from the Public and to generate some funds, we knew that the second part of the job was in store still, the dressing of the stones. There was no wind forecast for today so it seemed an ideal opportunity to tackle the job!

Last time, we tested our work after assembling the pintle bearing at the top and centralising the Lantern pinion, by turning the sails by hand.

After leaving Mostert's Mill last visit, I realised that it would be good to have the Pintle Bearing bored true, now that the pintle itself is set firm and vertical in the Vertical Shaft. I asked Neville to collect the two halves from the mill, he gave them to Pieter, who brought them all the way to Compagnes Drift Mill in Bot River two weeks ago, and I dropped them off at Orbit Engineering with specific instructions as follows:
 
1 Mark 1 and 2 permanently in blocks (we had marked them with chalk. There are two X's to show how they go together, but the 1 and 2 show the top and which way around we removed them).
 
2 Measure the full length of the two blocks together.
 
3 (Having established that they had 3mm steel plate) Machine off 3mm from each side of both of the mating faces of the bearing halves.
 
4 Make and attach 2 steel shims 3mm thick to the mating faces of one of the blocks.
 
5 Clamp the two together, align, and bore to 43mm. (It would not matter if this didn't remove all the hour-glass wear. In fact it did).
 
6 Make a 3mm shim the full size of the end of the block.
 
7 Check the assembled length, it must be the same as 2 above.

Since the last gathering at Mostert's Mill on 14th February (See No 170), much planning has been done including a Friends of Mostert's Mill Committee meeting, leading up to a Work Party, arranged to suit everybody, on 21st March. The proposed jobs were worked out and a tool list drawn up.
The team consisted of, in no particular order, Neville Boyd, Paul Jaques (accompanied by his brother Roger), Steve Craven, John Hammer (accompanied by his gardener, Fortune), Morne Husselman, Pieter Breeuwsma and me. Each person had a job to do and we worked well together.
 
This is how the plan of action looked, to start with:
