I need to replace the nylon bushes in the rudder stock can anyone tell me where to get them from and any tips on fitting them - I am told they should not be lubricated.

I had some made up a few months back at C & O engineerig in Newton Abbot, Devon, but I would think that any engineer worth his salt should be able to do the same.
I did't lubricate mine, I'm told that they will swell slightly when in the water. They're also held in place by a few grub screws.
If you haven't already done so it's worth checking for wear on the rudder stock at the same time - mine was found to be slightly bent which caused the wear in the first place and therefore had to be turned down.

I made some out of a white nylon cutting board and they have lasted for years!! Only problem is I can't make four sandwiches at a time now.

nylon for bearings is a standard industrial material so most towns will have both a supplier and an engineering shop where you can get it turned to size.
investigate using ptfe which is also available in bars for machining. it doesnt swell up like nylon.

Delrin is best
nylon swells when immersed and causes sticking shafts. there's a man who goes to most south coast boat jumbles and sells cylindrical blanks of delrin and nylon which can be turned to suit (i made my own bow rollers on a wood-turning lathe.

If you use marine grade Tufnol you'll never need to replace them in your lifetime. I have made 3 sets over the last 10 years, my own being the first and they are still as good today as the day I fitted them and the boat is well used. The only prob is "its bl**dy expensive" stuff to buy.
