Workshop Tip No. 5
When you are sanding down strip and block wood, leading edges or block wood wingtips (other items too) you can monitor the progress of the shape by holding the object to be checked up against a light source.
The light source should be from above and behind the item you are checking thus casting a shadow onto the shape being created. If you are sanding and shaping a trailing edge for instance when you hold it up to the light source a shadow will be cast along its length. If the shadow is true and symmetrical then you know your work is finished. It not, then keep sanding, a little at a time until a symmetrical shadow is created.
