Some time ago, I got this idea, and was fortunate enough to have a friend, Ed Hellam, who liked the idea well enough to build us both one. He did a fine job, but since this was the prototype there was at least one lesson to learn. The original viewing pane was plexiglass, and I discovered that it would hold enough static charge to throw the scale off .1 gr., so another friend, Bob Smith, who I had helped to work up loads at the range, (using this wind box), built one for himself, and modified mine with a tempered glass piece to replace the Plexiglas. Thanks Ed, and Bob.
The essence of the idea is to have a scale set up in a box with a clear, operable cover, so that the trickler handle sticks through a tight hole in the end of the box so that a light charge can be thrown, the cover closed, and the charge trickled, out of the wind. It works very well. The scale is an old Ohaus that I picked up. It is actually more sensitive then my RCBS 10-10 and works fine. I take it apart for storage,and wrap the parts in an old piece of towel and some wash cloths and store them in the same box that you see here.
