I really liked Smitty's Ghost he posted recently and I wanted to make one. I use CAD at work every day, so it is my software of choice. I pulled Smitty's JPEG into CAD and proceeded to scale the photo so I could make a 1:1 print. To resize it I only need one correct dimension, and I remembered with absolute confidence, that Smitty said it was 2-1/4" between the forks.
So I scaled the picture to precisely 2-1/4" between the forks, snapped my construction lines and arcs, made sure everything was tangent, and plotted out a life size copy. Quick trip to the garage, all sawed out and squared up. The whole process took about an hour. As I am congratulating myself on my keen efficiency I notice this seems a little big. So I open Smitty's post (oh yeah now I think of that) and, 2" between the forks is what Smitty said.
So I think to myself, "dumb*ss". But all is not lost. After rounding everything over and a few minor adjustments, it is a cool slingshot. I have average sized hands, I like the way it fits, plus I think Smitty's design is just cool. Cut out of ash, stained with red mahogany aniline dye, and about 10 coats of satin wipe on poly. As I have been doing with the shared designs, I added a counteresunk insignia under clear epoxy resin. Thanks Smitty, it is a fine addition to my collection.
