Just finished my latest take-down. This one is Hickory-backed Osage. I got permission to cut some trees, but almost all the wood has paper-thin rings, is twisted 90 degrees in the length of a stave or is otherwise not good bow wood.
It got me thinking that I have been getting too much of that kind of wood and some of it is dry. It came to me that I could just make short boards out of some of it and back it with hickory. The elasticity of wood is almost all in compression anyway.
So, I sawed, jointed and ripped some three-foot lengths to about 9/16" thick, glued 1/8" thick hickory to what would be the backs, then glued blocks of Osage to the bellies where the handle and fades would be.
Then I turned the handle ends round in my lathe (leaving the hickory back at the surface of the round part), fitted them to the screw-together sockets I made (sixth set now) and tillered the limbs.
Of course there was lots of waiting time while the glue dried and fussy work on the lathe to get just the right slip fit that left room for a film of epoxy.
The bow is 66" nock-to-nock and 45 pounds at 28 inches. It has about an inch and a quarter of string follow when first unbraced.
It's quick and shoots like all my other round-handled bows. If I support the bow, rather than grip it, I can shoot a wide range of spines without spreading them all over.
Now for the photos.

Nice bow Jim~!
-
Love it!

Nice work, I especially like your take down fixture. Is it much heaver than a regular sleeve?
-
Nicely done Jim.
-
Looks very very good. What did you use for the screw-in part?

It is heavier, just as a guess, 4 to 6 ounces heavier??
" What did you use for the screw-in part?"
I made the parts from steel tubing and bar stock that I machined to be a snug fit in the tubing pieces. I welded the solid stock in the tubing, drilled and tapped one end in the lathe, then turned and threaded the mating part, also in the lathe.
I'm afraid this take-down method isn't DIY deal, unless you have a metal lathe and welder and know how to use them.

Interesting, thanks :)
I DON'T myself, but I know people that do. Might be a fun one down the track a bit :laugh:
-
Nice work all around. What are the outside dimensions of the handle?
I'd very be surprised if you didn't have a lot of interest from people wanting to buy handles to try on their own bows.

Nice bow all around. Very cool take-down hardware.

The tubing is 1.25 outside diameter. The leather is pretty thin, maybe another 1/16th of an inch to the diameter.

Very nice work both metal and wood!

The simple twist of the wrist is just to cool 8) good stuff
-
I misremembered about the diameter. It's 1.25" not 1.125. Will change it above, to avoid misunderstanding.

Nice one Jim...I still haven't turned me a set...guess I'm lazy :-\ or just burnt out turning all day,n last thing I wanna do on my time off is turn more metal :laugh:
-
That's pretty sweet. Is that just plain carbon steel? How many threads per inch did you use?

Yes, plain carbon mild steel. I used 3/4-10 tpi. I have another set to try with 3/4-16.
7/8-14 would be nice, but I don't have a tap that size and don't want to single-point the internal thread--too much time.

Pretty slick. Certainly not your average takedown
-
Yea, I would think fine thread would work best with threads that short

There are possible problems either way. A fine thread is harder to start and easier to cross-thread.
Both seem to be plenty strong. I'm having fun with these. This bow is very obedient.
