A while back, a good friend of mine gave me a couple of Osage billets. These billets had been prepared by a friend of his for use in the commercial takedown handles you can buy at some of the traditional archery supply stores that cater to the primitive in us. The only problem with these billets was that they had been shaped to fit the metal tube while they were still a bit too wet. This did not work out so well because once the Osage had dried completely, the fit inside the brass tube was too loose and there was no way to properly remediate the situation. My friend tried to fill the gap with glue but the pressure was too high for that to work. This is when he asked me if I could use them and I accepted, figuring I could make something out of them. When they arrived by mail, I looked them over carefully and found them to be very nice with good thick rings. They had a bit of character to them and only one of the billets had a back ring chased down, the other was only half done. I put them aside until I could figure out what to do with them.
They sat in my shop for a few months and every once in awhile I would look at them, I guess to see if I would get any inspiration. They were plenty long enough that I could have cut the spigot end off and cut a joint in for splicing, but I have plenty of Osage I can do that with. The thought crossed my mind about trying to get some metal tubing of the right diameter, but I deduced that this would not be an easy task. Then it came to me. Why not make a sleeve out of another non-traditional material: fiberglass. I have used fiberglass for auto body repairs before, and it is quite strong for its size. I had nothing to lose, plus I had all the materials I would need on hand. Here is how I went about making this twopiece takedown.
The limbs had been cut out on a band saw, so the first thing I did was to clean up the saw marks from the belly and sides. The limbs were a bit less than 34" from tips to spigot end, so they were plenty long enough to make a bow for my drawlength, and more. They were also about 5/8" thick by 1¼" wide so I knew I could make a bow of at least 50# at a 28" draw out of them. I then finished chasing a ring on the one limb. The fades had been roughly shaped so I didn’t have to do any work on them for now. Next, I removed the dried glue from the spigots. (photo 1): The two limbs before working on them.
I have never made a bow using the commercial metal tubes—lack of interest being the reason—so I had no idea of their length, other than what I had seen in pictures. I started out by laying the limbs end to end so I could calculate how long of a handle I would need to fit my hand comfortably. I settled on a handle length of about 5", although I realized later on that I could have made the handle shorter. A 5" handle however, would leave a space between the two limbs since the shaped ends that were to be inserted into the handle piece were not long enough to butt together. I would therefore need a spacer. I didn’t want to leave that empty space inside the handle as this would weaken it. The ends that had been shaped for inserting into the commercial handle were about 2" long so I would need a spacer of about 1" to give me the 5" handle I was looking for. I decided to use elm for the spacer (it’s a tough wood that takes quite well to glue) and shaped it to match the shape of the Osage ends that were to be inserted into the handle piece.
I figured that the majority of the pressure exerted on the handle would be on the belly, at the opening of the handle, and back where the spigot ended with the sides of the handle merely holding them together. I also didn’t want a round handle but one more narrow and deep, in keeping with the general shape of the limb spigots. With that in mind, I started cutting strips of glass cloth. I cut a couple strips the full width of the handle and fairly long so that I could wrap them completely around. These would be the first pieces that I would use to establish the base of the handle. I didn’t want them too long though, as it would have made them unmanageable. Since my plan was to lay a number of narrow, 1" wide strips along the belly and back to build up some depth and add strength, I would also need a few narrow strips, about 1" wide and long, to wrap around the openings to secure the ends of these strips. I also cut a number of wider ones, about 3" wide, and about 6" long to build up the center of the handle, and also to hold down the narrow back and belly strips. Next, I cut a large number of the 5" long and narrow pieces that would lie down along the length of the back and belly of the handle. I wanted to do as much of the glasswork as I could in one shot as the resin I was going to use is quick-setting, so I tried to get as much glass cloth cut up as I would need.

I carefully sighted down the limbs to make sure I had proper alignment and made adjustments accordingly. I then mixed up a quantity of polyester resin and started by brushing some lightly on the spigots. Then, using the long full-width cloth, I wrapped it around the handle, applying resin as needed to keep the cloth wet. Then I applied a number of the short pieces along the back and belly, followed by the narrow, long pieces along with the wider, long pieces to hold everything together. It was messy work. Polyester resin sets extremely fast (about 5 minutes), so applying all the cloth in alternating layers was impossible to do in one application. It took three applications (about an hour) to completely apply all of the fiberglass and make the handle to my satisfaction.
Once I was done, I let the bow sit for a couple of hours to give the resin time to cure. Finally, I separated the handle from the limbs: the fit was quite tight. The step up from the spigots to the limb proper was a bit more than 1/8" and now the fiberglass handle was pretty well flush with the limbs so that would give it a wall thickness of at least 1/8".

Even though the job I did with the fiberglass was pretty smooth, there were some areas that needed to be worked on. I sanded the handle down to give it a fairly smooth and uniform shape: I did most of this work outside since fiberglass is toxic. The finished dimensions of the handle came out to 1¾" deep by 1 3/8" wide at the center and 1 5/8" deep by 1¼" wide at both ends. After sanding the handle down, I once again clamped it in my vise and flexed the limbs by pushing on the tips. Still no flexing of the handle, so I continued tillering the bow out. The overall length of the bow was 69" long so I knew that I could get a 30" draw out of this bow. Tillering the bow out was fairly easy and uneventful. I was quite concerned that the handle would give out along the way but it didn’t give me any indication that it was being stressed too much and easily held up to the bow’s finished draw weight of 65# at a 30" draw.

I’ve shot the bow many times since I finished it and I am always pleased with how well it shoots. If you are thinking of building yourself a two-piece takedown, perhaps you should consider this buildalong. The most interesting aspect of this type of takedown is that it could be made with a reflexed handle or a deflex handle just as easily as with a straight handle. This gives one the ability to make different styles of takedown bows.
