Nut-Shooter Update 6.2.13: Most of my wood is hard.

There's only about 6 inches of softwood (pine) in the gun cocking mechanism. The rest is birch.The plywood frame is 99.5% complete. I just need to add in a cotter pin or something to the end and it'll be done. Tomorrow (time-permitting) I will be cutting my own slingshot bands from some exercise elastic, Theraband Gold. I'll be following Jöerg Sprave's band calculator: http://www.slingshotchannel.com/band_calc.html which handily informs you what thickness bands would be appropriate for your desired draw length and weight. We are on track for filming on Monday... or Tuesday depending on the weather. See you soon, YouTube...
