Hi all,
I don't have much of a shop to speak of, just what I can get away with at work. I do have aspirations though....
I'm limited to mostly the final assembly and finish.
My first project choice however is a bit, er, different shall we say?
I have had the design floating around in my head for years (decades, actually) and I'm finally acting on it.
I grew up in Hawai'i, did a bit of pig hunting in my youth. Didn't use dogs (didn't have any) or guns. Just a spear with a knife as backup and tracking skills, then waited for the opportune moment.
I was moderately sucessful, about 18 kills. Largest I took was about 120 lbs (a sow), most were in the 50-80 lb range. Never had to track any wounded, but I did come back empty handed a lot. Yeah, I know, lolo.
Sooooo, here's what I have so far;
Think of a Zwickey broadhead on steroids - O1 tool steel - .250" thk - 4"x18" OAL w/5" of haft space, 12" sabre ground double edge. Blanks were waterjetted by ArroJet, grinding graciously and expertly performed by James Terrio, HT by Peters. The penetrations are more for balance than bloodletting, but that was a consideration. James said the blanks weighed about 2.5 lbs before grinding, 2.0 lbs after.
Hafting will be done with 36"x1.125" Bocote shafts, split haft with 2 .250" stainless shoulder bolts (basically a Corby) utilizing steelbed, then coxcombed (pattern yet to be determined) at the foregrip, aftgrip and balance grip areas with size 5 Kevlar thread and overcoated with high-strength color textured epoxy. Butt is copper capped on a .250" stainless stud w/a heavy stainless washer and stainless acorn nut. I hadn't really considered a crossbar, never used or needed one before. I don't think a lot of paleopeople had them either.
The haft is short for two reasons - Firstly, you ever try to hump through brush with a 72" to 96" spear? Shorter is better, one of the few instances in life a man can say that.
Also, it's not truly for throwing, so the extra length isn't necessary. It will be balanced for thrusting, not throwing. A shorter haft also lessens high-leverage stress on the head. An added benefit is in the event I should try to sell a couple of these (I'm building 6), shipping is easier. 
Here's a sketch of the general idea....
I'll try to keep this updated as progress is made, but I'm a working man, so it'll probably be a little slow. Hey, what's a bit more time?
Thanks for looking, I'm looking forward to some comments and suggestions....
