You're a braver man than I am. I would have just left the teeth tacked on until after the trial fitting. Don |

I had 1 more job to do before taking the gear to the mill to fit . I drilled a hole in each of the 8 sections to allow water to escape as every few years the mill floods, some times to a depth of several feet . I keep the slugs from the holes as they are easy to turn into thick washers Always believe in waste not want not Mike |

I am in awe. How do You get the info/skills on what needs to be done ? As for bearings .. the igus engineered plastic would probably be excellent, cheap, and they might comp You. If You want, I could ask them. |

The proof of the pudding is in the eating .as the saying goes so with no more ado loaded the gear up and went to the mill First photo shows how worn the original gear was . the next are of fitting it up The original horizontal axle tree shaft is long gone and has been replaced with a 9 inch square solid cast iron shaft . When this was done the center of the water wheel was reduced to 9 inches but the pit gear was replaced as this has a 9 inch square hole from new . I think this was carried out in about 1850 as far as i can ascertain. It is very difficult to get details about work carried out and when as so little was recorded I know that in 1980 the wheel ,stone work and sluice gate was rebuilt . They never went any further either due to lack of funds or interest. Over the next week I will finish fitting the gear and to get a correct mesh I need to realine the wheel shaft . I will need to move the whole wheel, shaft and gear out about 40mm . This will not be a problem as the plummer block bearings have never been bolted down . |

The shaft is supported on a steel shaft fitted into the end of the axle tree shaft This sits in a bronze bearing which is held in a cast iron block with 4 adjustment screws This is completely worn out . I have some suitable bronze but not a lump big enough so will make a steel housing with a replaceable insert The wheel shaft bearings are ok Mike |
