This mule deer antler slingshot has no finish and no grooves cut for band attachment. I like the natural curvature of the antler. The handle has a piece chipped off (visible in a couple of the pictures); I'm not sure what caused that. Due to the sideways curvature of the handle, it fits better in the right hand.
The slingshot is fitted with gypsy tabs attached to the antler with Spectra thread (a layer of wrapping against the antler, then another layer to hold the leather tab in place). A spot of glue fixes the end of the thread after all the wrapping is done.
The tubing is from McMaster-Carr. The current setup works well with 1/2" steel, but gives hand slap with 7/16" and 3/8" steel.
With the setup shown, I have to adjust the tubing at the tab before each shot, so I will probably change the attachment so that the tubing has a bigger loop at the tab.
