Hello friends! This here is my first post on the esteemed "Bows" section of the Primitive Archer forum. There are some absolutely amazing bows and bowyers on this site, and this seems to be the most expert place on the internet to seek advice and share stories about bow making and I'm excited to be part of your community
I'm new to the craft, and someday I hope to post pictures of my masterpieces like airkah and SebastianArc have recently, but for now I wallow in the debris of broken limbs and hearts. Here is an account of my tribulations thus far:
Bow #1: Umbrella pole of unknown wood, 66" N2N, 1 1/4" wide to 5/8" tips.
Accidentally cut the arrow shelf into the back of the bow before tillering began.
Bow #2: Cedar with hickory backing, 65" N2N, 1 1/4" wide to 3/4" tips.
Followed instructions outlined by Saxton Pope in 'Hunting with the Bow and Arrow'. Bow chrysaled immediately upon bracing.
Bow #3: Cedar with thicker hickory backing 68" N2N, 1 3/8" wide to 5/8" tips.
This time followed instructions described by Howard Hill in 'Hunting the Hard Way'. Exploded on the tillering tree, nearly killing my cat.
Bow #4: Osage orange, god bless it, 59" N2N, 1 1/4" wide to 3/4" tips.
Someone finally gave me Gary Davis' movie and explained the concept of chasing a single growth ring on the back of a bow. It was going to be 68" long, just like Gary says. I carved the back out real nice, then I took it to my uncle's shop and it was a 59" bow before I could utter the first syllable of the word 'bandsaw' (which is now a curse word for me). Tillered it with tears in my eyes into a whip-ended half-moon with 2" of set (see photos), but it still pulled #53 at 26".
I will admit, I was not very proud of that bow at first, but over time I grew to love it, shot 200+ arrows with it, all of them in the bullseye, until one day I drew one back and heard a horrible cracking noise. A splinter raised up on the back of the bow. I couldn't save it. More tears, then on to the next one.
Bow #5: I just messed this one up yesterday. Red oak board backed with wild cherry bark. 66" N2N, 2" wide to 3/8" at the tips.
I got all hopped up on Marc St. Louis' article on heat treating (TBB IV), so I made a fire, stuck the limb over it, and scorched it into 3" of set. Even worse, while the limb was hot, I decided to try and bend it straight, so I wedged it between the slats of an old pallet and torqued her until I heard something crack. Not sure if it was the bow or the pallet. Either way, the limb was still crooked. There was no choice but to back the bow and hope.
I glued strips of wild cherry bark on with Titebond III wrapped with bicycle tire innertubes. After curing, I pulled the tubing off, looked pretty good, but there were some ripples, which I proceeded to sand into oblivion, breaking through the cherry bark and revealing the wood underneath, most likely rendering the bark useless and giving it a strange Persian rug appearnace. I decided to continue the tillering process anyway, and eventually I was able to brace the bow. It didn't take any more set than the 3" I scorched into it, but I didn't like the looks of it, so I cold bent it onto the form and then (carefully this time), roasted it over a fire. And success! It was now even slightly reflexed in the handle!
I was excited to finally get some positive results, but after all the abuse I put this board through, I took to tillering in a helmet, ski goggles, and medieval chain mail. I was hoping for 50#, so I worked it down to 55#, then 50#, then 45#, then #40. Every time I got close to my draw length, I heard a little crack, so I scraped off more wood and tried again. Still crackling. Scraped off more wood. Crackling getting worse. Finally I said screw it, there was no way this bow was going to survive, and if it did it was going to be 15#, so I pulled it back to my 26" and KABLOOEY, it exploded out of my tillering rig. I figured the break point would be where I scorched the limb over the fire and tried to torque it back to straight, but that was not the case. I was interested to find it was the other limb that broke (I am becoming the Sherlock Holmes of broken bow diagnostics).
There always seems to be one mistake that I make during the process that ends up defining the shape and tiller of the bow. This time it was an innocuous clamp mark on the belly of the top limb. I didn't think it was anything to worry about. Gary Davis doesn't use scrap wood to protect the belly of his bows when he clamps them. I remember it was mentioned once in the TBB, but only if the back of the bow was to be clamped. The mark was barely visible and I completely forgot about it until I was inspecting the splinters, and then it all made sense. Even though the mark was almost gone, the damage had already been done. The wood fibers were already compressed. The helter-skelter cherry bark backing didn't have the tension strength to hold up the crushed fibers underneath it, and kaboom. That was it. What I should have done, if I'd known it was going to be a problem, would be to treat it like a knot and leave more wood around it to compensate for the crushed wood fibers. Or maybe lighten up on the clamping pressure a little bit. Oh well. On to the next one.
Bow #6: Burlap backed live edge elm slab I plan on turning into splinters and broken hearts tomorrow…
Thanks for reading. I'm so glad there's a friendly place on the internet to exchange ideas, stories, and knowledge about building bows. I look forward to many fruitful and lively conversations in the future.
