SanFran 12 Posted August 17, 2014 Share Posted August 17, 2014 I am coming on to the hardstand next week for the annual thrice over.... You know, you start out with a list of half a dozen things that you want done before the summer, and end up doing only half of them, then adding another dozen things you didn't know about. Almost got to a stage where I have a list of lists for the boat.... the plumbing list, the electrical list and so on. Anyways, one thing to do is to try and eliminate rudder sloppiness. I have a stern hung rudder and the wear between the two parts is getting worse. Without having to remove each of the two brackets (to get machined) is there a way of getting a nylon bushing made to the correct diameter to fit over the pintle and take up the slack. I'm guessing that the wear wouldn't be more than half a mm. Has anyone come across this problem before? Link to post Share on other sites
Dambo 44 Posted August 17, 2014 Share Posted August 17, 2014 The issue you have with not machining, is that the hole won't be an even round. There are places that could turn you up some very nice bushes to go in, but without machining, you'll shorten their life due to the uneven wear. Link to post Share on other sites
Dusty 0 Posted August 17, 2014 Share Posted August 17, 2014 Best to make a proper job of it and machine them out, Anything you do in situ is going to be short lived. Half a mm is not enough to play with for synthetic bushes. Link to post Share on other sites
SanFran 12 Posted August 23, 2014 Author Share Posted August 23, 2014 Cheers for that. If I machine the bolt, the 'pin' I dont want to weaken the hinge. I think its about 25mm so maybe half a mm might not be too bad. Link to post Share on other sites
Dambo 44 Posted August 24, 2014 Share Posted August 24, 2014 It'll be fine but do put a nylon or similar bush in. I think this is the crowd who've made stuff up for me in the past: http://www.dotmar.co.nz/nylon.html I gave them the specifications and the application (salt water environment, self lubricating, long lasting etc) and they advised the best product then made them up for me.

wheels 543 Posted August 24, 2014 Share Posted August 24, 2014 An engineer will direct you to the best material for the purpose, but Nylon is not it. Nylon absorbs water and swells and will then grab, plus it will wear badly. A self lubricated bearing Plastic is best and as Brain isn't working fully yet, I think it s called Delron. But please get that confirmed rather than just asking for it to be used and finding it the wrong material. Link to post Share on other sites
