Terry,
I built a laminated long bow with some components from Bingham. I used instructions from an article in Trad Bow Magzine from about two years ago. I went to my local cabinet maker/speciality woods shop and bought a "scrap chunk of Mahogany and Teak, and a six foot piece of Black Walnut. He cut it to dimensions and planed it for me, about $30 total and I have enough wood for two more bows. I bought fiberglass, epoxy and leather for the grip from Bingham, about $25-30 with shipping and all. I used a straight 2x4 for my form. I made my clamps with flat stock and all thread, probably, another $20-30. My heat box, I made out of scrap pressboard, and used an old strip light fixture with 4 or 5 200 watt light bulbs as my heat source. I lined it with foil to reflect the heat back in and prevent a fire. I used a dial meat thermometer to check the temp. A little trial and error to get the right number of bulbs and combination of wattage, but it worked. My boss sent me the horns from a baby whitetail he had killed years back, I hacksawed and sanded that down for my nock tips, adds a nice touch! I used tung oil as a finish, about $6-7 for a bottle. You need a wood rasp or two, a small round file for the nock (I used a pico sized chainsaw file), power sanders are nice, but a block of wood and sand paper will work too, I used a table saw to cut the profile of the limbs, a jig saw to cut the riser and Gorilla glue for the wood laminations. I probably have a $100-125 in everything and I have enought left over to make two additional bows. So the first one is relatively expensive, the next two are paid for already, I just need some more fiberglass from Bingham.
I also followed the directions from another Trad Bow article about making bow strings. I bought a spool of plain old brown (I think it is 8125) string and made my own.
I turned out to be about a 58# draw at 32" (I've got longarms), 70" longbow. I took it to Idaho for a late season mule deer hunt last fall, we got soaked for two days and snowed on for the third day, but the bow held up well.
I leave this Thursday for opening of archery deer and bear in the Sierra Nevadas with my homemade bow in hand, can't wait!
Also I built a tiller stick so I could check my poundage and symmetry of the bow. This took another 2x4, a couple of pulleys, a length rope and some eyebolts, a scale and some screws. I had all of this stuff around. So I didn't have to lay out any cash.
Have fun and patience, it takes a little thinking for the first timer.
Let me know if you have any questions, I'll try and answer ASAP.
Happy building,
Chris
