After buying some abs buoys on ebay and when they arrived they were two halves of a ABS moulding that had to be cut out and joined together I began to look for suitable substitutes, chrismass tree bourbles make great buoys, just fill in the shoulder with some p38 and sand down to a smooth finish, spray them and hey presto you have a buoy.
Wilkinsons sell a pack of 30mm bourbles for £2.00 or Asda sell 27 25mm bourbles for £1,27, I ave used the buoys for the last year on my Arun lifeboat in the picture , the crewman is holding a 30mm Xmas bourble.
Mrs lifeboat cant believe how interested I am in looking round shops at Xmas decs!
