Runar,
I didn't understand the last part of your post until I got down to the last picture. Then I understood completely !!!! My work space looks very much like yours and I am constantly banging either the barrel or the butt stock of any rifle on the over head, the walls, other tools, the lights....everything. Too bad I don't like to distress my rifles...all I would need to do is not take them outside for the final smoothing operation.
I always enjoy your posts.
