Cap'n I can relate to your pain , As a result of a work related injury nearly 2 years ago I have had hip surgery, knee surgery, and this Friday I will have a 3 level fusion on my lower back.
Keep your chin up and keep doin' what you you can.
BTW : I just received my mintor 22 for Storch project, but it will now have to wait for about 6 month of more.
