Well to all that have been kind enough to give input, I'm here to tell you that work on this and all other projects are on extended hiatus. It seems that on top of all the other physical maladies that get you in your 60's I have decided to go with a big one and have a detached retina. I'm a week and a half out from the emergency surgery that hopefully will have saved my eyesight on the right side. So with no depth perception and less desire for eyestrain in my functional eye I put all work on hold indefinitely.
As of the post surgical Dr's visit I'm told things are coming along well but it will be multiple months before my sight returns. Ah the joys of aging. Oh and this also prevents me from having a hunting season this year. How wonderful to have an extra month and a half more time with the wife and think of the money I'll save. Pray for us both!
