Osage HLD Flatbow- “Irma”
« on: October 04, 2017, 10:17:58 am »
Almost done with my first hollow limb effort, almost done.  The bow is pulling nicely. Just needs finishing.  Here are a couple teaser shots.

Thank you kindly, Clint.  I do believe I've taken some cues on that from your work. ;)

That's a tease for sure, but knowing your work I'm sure this one'll go down in the books. Looks awesome so far.

Beautiful work. What is the purpose for scooping the limbs like that?

Looks really nice. 

I'm sort of wondering how durable such a design is.  I heat-treated an old HHB bow with fairly wide, thin limbs many years ago and the end result was essentially a hollow limb bow.  When I braced the bow and tried to pull it back the limbs split right down the middle from fades to nearly the tips.

Lookin good Steve! I did a mild hld static a couple weeks ago. I like it a lot! Yours is hollowed out more than mine though. I had a slight crown to work with

     Marc, I had the same exact thing happen to me a while back.  I had spent many hours hollowing out a highly-crowned character stave, from an Osage sapling pole I felled, and when I started bending it, I kept hearing little ticking sounds.  Sure enough, that thing split right down the center of the limbs.  I just sat there looking at it completely deflated.  But I will say that I had wondered prior to that build, what would keep a wooden bow limb from suffering the same radial grain line checking, that occurs when felled logs are left full-round and unsealed.  When you cause the crown of the limb to flatten, every one of those radial grain lines are trying to pull apart along the belly.

     -That said, I have made a couple of slightly HLD (shallower in the belly) bows - one Osage and one CrepeMyrtle shorty - that did just fine.  I like the idea and the science behind it, not to mention they look sexy, but once you see one split itself in two, it kind of makes you take a step back.

Looks good! what kind of crown are you working with?

That's interesting, Marc. I see what you're saying. Something to think about. I wonder if Simon has experienced that. He's made quite a few. I wonder if certain wood types hold up better to that particular kind of strain and others don't.

l love the look of the handle. I am also wondering whether certain woods are more suitable for such a deep HLD design than others. I can totally visualize what Marc and JohnL are saying. One way to figure out the radial tension would be to apply a strain gauge, but I have only dealt with them for larger structures so I would have to research it a bit on whether they are available for something the size of a bow.

It's certainly crossed my mind, as well.  Especially putting in the extra time on the hollow limb.  It's been done primarily with a goose neck scraper.  I'll need to get a better tool if I intend to make more.  That goose neck is tough on the hands.

I'll be interested to see how it holds up, Marc.  It's going to my buddy as a gift.

Thanks, Weylin.  Not much crown.  It'a a 4 year old stave from Kansas.  Good Osage with one clean knot on the lower limb.  We'll see how it does.

 I love hollow limb design but I like to keep the centre a little thicker than the edges. I've only used it on high crown timber though.

Thanks for the compliment, Bill!  I feel a lot more focused these days. ;) ;D
