I built one ~ 35 years ago, but certainly not as nice as what you are building. Let me just say that you will really appreciate how handy they are - a really great way to hold your gun while working on it. Actually, I pulled mine out of storage just yesterday to work on my neighbor's new 22 magnum rifle to install a scope mount.

As I age my memory fades .... and that's a load off my mind!

“The problems we face today are there because the people who work for a living are outnumbered by those who vote for a living."
