On tenter hooks, and a rare weather phenomenon

The new steel yards, welded to a cranked shape, are being set up with the tentering gear. These mechanisms would allow the gap between the stones to be minutely adjusted, according to the speed of rotation of the sails. The layout has been deduced from evidence of the remaining parts of the originals.

Meanwhile, work is progressing on the new joists for the bin floor. Also, the stonework around the spliced beam ends on this floor is being reinstated.

We were treated to a 'fire rainbow' today - a coloured arc in the sky caused by light passing through ice crystals in high level cloud. I think the proper term is a circumhorizontal arc - quite a rare phenomenon at these latitudes.

More splices - bin floor this time

The southern beam ends on the bin floor had gone the same way as those on the stone floor. The remains were more like compost than timber, with a few birds nests thrown in for good measure. Splices had been cut and today they were lifted up and we started to fit them.

South-east beam end on the bin floor

South bed stone hoisted back up

After a bit of scaffold tweaking, we were able to lift the south bed stone up to the stone floor today. Not easy, even with modern lifting tackle. Must have been fun in the old days! An interesting filler has been used in a pit in this stone - looks like it's lead.

North stones back in their rightful place

The North stones are now set up, with the drive gear all in place and a new kerb installed.

A new door...

The original door to the bin floor has been absent for some time. The opening had been blocked up with timber and wire mesh. To improve the weatherproofing of the mill, a new 'stable' door has been made. This was fitted today, with the surrounding frame assembled on site and fixed to the stone. Long term - this will help with access for long timbers and so on...

Stone floor; boards, joists and discrepancies

With the Hurst frame complete, work has been proceeding on the main stone floor, inbetween other tasks! This hole is for the south pair of stones, which will be reinstated once the floor is finished. The boards adjacent to the tower wall will be removeable, giving a space through which the stones can be hoisted.

The joists to the east and west side of the stone floor have had to be replaced. Each of these joists has one end set into a socket in the stone wall and the other housed into the Hurst frame This is a view looking up at the western joists, from the main door. For reasons not clear at this stage, the Hurst frame beam seen here is significantly lower than its opposite number. We will have to pack up under the floor boards at this end to take out some of this discrepancy, otherwise the stone floor will have rather a 'unique' shape.

A bit of a fiddle with the new bolter cylinder

The new bolter cylinder is coming along. An elm spindle has been shaped to a hexagonal cross-section, and the original ironwork has been fitted at each end. This was a tricky job, if only we had a 16 inch square drill bit! With the iron bands driven up and everything eventually snug, the spokes could be added. Three holes at the appropriate spacing (dredged up the old school geometry from the memory banks!), then the spokes were driven through to give, effectively, six spokes. The longitudinal rails will then be added (the first can be seen at the bottom of the photo).

The 'crank' in the tail end ironwork seems to correspond with wear marks on the original cabinet at this point. We assume some sort of reciprocating mechanism was used to help feed the bran through the chute at the end of the bolter, to prevent it clogging up.
