I have worked a lot with purple heart, and found it's stability to be fine - made a series of finger-joint boxes for my wife's family in Brazil. I have also, much more recently, made some grips for a 1911 and a cowboy gun. All came out beautifully, and the color is preserved by several coats of lacquer.
As a fellow Vet, I really appreciate you looking out for one of our brothers. Ask him what HE would like to do. And if he wants to make a kit build such as Kibler ships, help him pick out one he would like to treasure.
Me sitting around all day on my pity-pot led to me starting a small gunsmithing business, and now has me pointed toward this Herman Rupp I am building now. Having a lot of fun with it! Next week tho, I get to spend some time at Cleveland VA Hospital, so will have to take my sketchbook, and my gun building books with me.
Don't know if Afgan Vets use the phrase, but - "Welcome Home, Brother!"
