Not totally primitive with this one, but...Some years ago, I saw a screw-together take-down system attributed to James Duff. It was illustrated in volume III of the Traditional Bowyer's Bible with a comment that the threads would have to stop in just the right place to line up the limbs.
I thought that was a fallacy because the roots of the limbs were round and fit in the round ferules.
The two ferules could be screwed together snugly before the limbs were glued in. Then the limbs could be glued into the ferrules in line with each other. After the glued had set, lining up the limbs would be simply a matter of screwing the threads together snugly--where they stopped, the limbs would be in line.
Well, I tried it over the last few days with a couple of billets from that Osage I cut a couple months ago. Here are photos of some of the steps.
It's a light bow. Pull is about 37#. It weighs about 28 ounces--about 10 more than a bow without the steel handle fittings. It is 66" long along the string. It's a nice shooter.
Hope you enjoyed the sequence.

Neat bow! Where did you find the ferules?
-
cool! i was wondering where you got the furales as well

Made them. Guess that may be a little bit disappointing... I used welded tubing, only because I didn't have seamless. Bored out the weld bead inside and machined mild steel slugs that I welded in and then trued them in my metal lathe and threaded the parts. The ferrules are a little rough looking without the leather, since I just used what I had.

hmmm i may just have to go to the shop and do some experamenting....

Very nice bow. Having made your own sleeves make it even better!
-
Really great! love that you made the sleeves. Pretty bend in that one too.

That's just awesome! Thank you for sharing this :)
-
Yup, nice work, much cooler having done your own ferrules.

I like that set up,other than making the ferrules looks easier using the wood lath than fitting the ones I get from 3 rivers. Very cool. :)

Very nice, my friend. Ive never done a take down. Jawge
-
That's a very cool idea. I wish I had the tools to do that, but, then I'd have to have a bigger shop.
-
Exactly what Mullet said! I just built a shop two years ago to build bows. Now I have to build one to make steal parts . MyHeads spinning. Maybe I can just buy some. Nice bow, great job!!!
-
Thanks for the comments everyone.
If you make this setup, I think it is important to leave at least the center part of the back ring intact so it is not cut where it enters the ferrule.
-
Yeah, the back of the bow was my concern when I saw the lathe.
-
Hey Jim! That is one awesome bow! I've already said this once today but I've been wanting to make me a take down as well. I think I may have to try it though I don't have the expertise to make the ferrules like you did.
On a side note, what part of Kentucky are you in if you don't mind me asking? I'm a little south of Lexington, in a little town called Berea. I actually know several bowyers around here but as I see it, it never hurts to know one more!
-
Oscar, I'm in the "Purchase Area" near Murray and south east of Paducah. We visited Berea when we were looking for a place to live. Nice country and a lot closer to good trout water than where I am.

Wicked cool 8)

Neat can't really tell it's a takedown when together!
-
nice setup, what size tubeing did you use anyway, Bub
-
Bubby, I used welded steel tubing that happened to measure very close to 1.125 inside diameter. I chucked the sleeves in my metal lathe and bored them to right at that diameter. (That also removed the bump from the weld.)
If I make many more, I would try to get some seamless tubing that would be that size and have no weld to worry about.

Very cool! I've used the store bought sleeves , and have tried to come up with some sort of screw together whatchamacallit, but never figured anything out. Thanks for sharing your invention with us! Dale

Just for the record, no way did I invent this. I saw a similar setup that was marketed in the 1920s. I don't know if it used round sleeves, but it did use a threaded connection.
