Cleaning up the portside propeller Shaft & the propeller to find out the diameter and pitch & the manufacturer of the propeller

Chance like a lot of James Silver / John Bain designed boats at the time Chance was build, they were twin screw single rudder designed. 



The stern gear glands were of white metal and were very close fitting glands




The original propellers that were fitted when Chance was originally launched in 1948




The original manufacturer of the propeller can be seen as Thornycroft  




On this photo is can be seen that the diameter is 17 1/2 " x 12 1/2"




These propeller shafts will have to be removed as there is work to be done on the stern tubes and the bearing changed to modern stern gear when Chance is re-engineered

A big shout out for a cover to put over Chance so we can get on with the restoration of Chance.

 At the moment we are in this position with Chance, We have a large poly sheet over Chance which keeps getting blown off as we can not fix it down very well and is a thankless task having to keep pulling over the boat until the next major gale of strong wind decides to remove the cover again.  That's the position at the moment, what we are looking for is a shed/workshop like the one over Helen Wycherley Heritage Restoration project in Whitby North Yorkshire. This type of shed/ workshop would do our restoration project a world of good and make possible for us to get on with our restoration of Chance.    So if anyone out there can put us in contact with anyone who wishes to move on their poly tunnel shed/ workshop, please get in contact with us through our social media channels. This would help our restoration project get underway again. Te cost of building a new shed is way out of our price range and without some help it is looking in a grave way as to how to move for...

Chance Autumn update

As many of you will have seen from the lack of updates there as been little work done on Chance over the summer. This as been due a lack of time and more over a lack of funds to do major task done on Chance. especially the removal of the middle and aft section of the starboard beam shelf and reconstructing the transom and its framework which holds it in position.   However, all is not doom and gloom, has I have been able to take on an apprentice to help me during the working week on my clients boats and leave myself and wife time to get on with working on Chances repairs.  So hopefully over the coming week's we should be able to make a start on getting the beam shelf removed and replaced with a new correctly fitted beam shelf which will bring the hull back into position  along with the ribs and frames which have to be replaced at the same time to get the hull back into its correct position once more.  There is going to be a lot of shoring up of the starboard sid...

Next Job at the stern of Chance is going to be to remove the Rudder on Chance

Image
 Now having removed a number of planks on either side of the hog as found that the inner hog is in need of replacing. This means that we will have to remove the rudder tube. This means having to remove all the frame work from the transom to expose the rudder tube. The rudder tube in this photo is sitting on two shaped wedges on top of the hog.  Also all this aft deck planking is going to have to be removed as well. no easy job as it was laid down with galvanized screws which have been in place for almost 80 years and will very likely not come out without a lot of damage to the teak decking, so it is likely we will cut off the screws between the deck and the deck beams. This is not a problem as the deck beams have to be replaced anyway because at one end they are not fixed and at sometime in the past were cut short. So now the fun will start dismantling the aft end of the boat more to get the hog repaired and the whole of this area rebuild as strong as when it was first build....
