At the last Open Joe had problems getting his centre-board up and down. We have found two problems: too much paint [freshly painted by the previous owner] with numerous high spots which can be sorted by sanding AND a bent brass bolt.
What size,and type is the best replacement? Where can I get one? The current bolt is 10mm diameter ans 80mm long. The rubber washers seem to have perished as well.
All help much appreciated. Hoping to fix it in time for the next Open.

Pinnal And Bax sell Satianless SteelCentre board bolts for about £4.50.
Last year I had a problem with my centreboard bolt and as a rubber washer I went to the local hardware shop and bought the largest flat tap washers I could, drilled them out and when I fitted them added a little silicon sealant to them. THey have not leaked since! and the board goes up and down easily.

Little tip for centrplate bolt - use bolt which matches the size of the holes in the plate case plus washers. However to make it rotate more easily, insert a bushing in the centrplat itself so that the loading is between the bolt and the bushing and not the rough surface of the hole in the centreplate. I've seen various attempts at making a hole in a wooden centrplate and then make it smoothe enough for the board to rotate easily and the only one which come close to using a bushing is to create a solid area of expoxy and drill through it with a very high speed drill - creating a very smooth load bearing surface.
Quite correct that all high points need sanding off the main surfaces of the board.
One other tip .... anyone had problems with sealing up the bolt and having to re-seal after removing the plate (as you have to do when using something like silicone sealant ? Car body filling compound (not sure where to get it these days - I used to have an old tub of the stuff). Essentially it's like chewing gum and stays like that for years. Seals up the bolt 100% even after removing and re-fitting the plate numerous times. Only down side is the poxy stuff is hellish to get off your fingers !
