Rounding Timber Spars
by John Sheen
Here my handy tip for rounding timber spars, oars etc.
Take a piece of plastic/PVC drain pipe slightly bigger radius than the work piece, and cut it in half.
With three pieces of double sided tape attach glass paper, preferably the belt sander type, which avoids frequent changing, to the inside.
This works on any radius and is improved on larger items by fixing a handle to the top of a bigger pipe section.
This home-made tool works better the longer it is. Start across the grain and then with it, changing the grade of paper as necessary for a good finish.
