Just a small update.  I have not forgotten about this project, but it is temporarily on hold.  We went on vacation and when we came back it was suddenly hotter than the sun outside. With temperatures over 118 F it is just too hot to get out into the garage. However the rains are coming, and my hope is that the temperatures will drop soon.  To that end I have cleaned up the garage and have it ready to go in case we have a cool day.
