Title: bamboo self bow build
Post by: superdav95 on January 28, 2026, 11:38:56 pm
hey guys. This is not your typical self bow build.  it will be a 58" ntn bamboo recurve self bow that where the limbs have been z spliced at the handle.  This was then put into a slight deflex at the handle and then glued to a handle.  I will be gluing a horn plate over top of the z splice on the back side and possibly finger grooves added later.  anyway here are some build progress pics.  Im hoping this bow will be about 50lbs at 28"

Yes I’m hoping it does well in speed testing to see if it will hunt at flight.  Fingers crossed.  I’ve got a couple heavy Turkish horn bows I’m going bring too to see how they do!  Should be fun.

Yes.  It’s moso and it’s heat treated.

Thanks rob.  Ya it’s just the bamboo nothing on the belly.  It’s been heat treated like my other builds so it’s basically a tension monster.  I made one of these steam recurve selfbows earlier last year but it was only 30lbs.  Shot nice but very light.  I posted a short video last year on it.  Typically with my bamboo bows they were 5 piece builds so was testing out the recurves really.   I had been testing many methods to steam bend bamboo.  It’s sounds easy until you try it.   We think of bamboo as this magical grassy wood material that we imagine will bend however we want.  The fresh green or even recently green stuff bends like rubber but when it dries and hardens it’s a different story.  The bamboo moso pole that I use is the larger diameter stuff which enables me to get the wider limbs.

That's awesome, I saw your youtube videos of the 5 piece bamboo ones and they are really beautiful. They look like a lot of fun to shoot! Really nice.
Do you do any flattening to the bamboo? I've only used bamboo for other fun projects but really want to make a bow sometime.

Thanks.  No heat flattening is done to remove the crown or rounded side.  I do use a series or rasps or belt sanders to remove material on the belly during tiller.  This gets the bend looking the way I want.  I’ve done build with lighter bows kids bows that were just narrowed and not tapered and they work pretty good too but for higher weight bows I use the full width with slight taper and narrowed tips.    Keeps mass off the tips but maintains draw weight.   We shall see how this one fares for draw weight.  I feel it will be around 50lbs.  Fingers crossed.  I’ve sent kits to guys over the years to experiment with.  Let me know if you would like one.

Awesome bamboo selfbow, Dave! I love the splice and handle work!

Couple questions…What are the dimensions (length) on your handle and fades?  Any concern with the handle popping off or will the deflex in the handle help with that?  I’ll be watching to see how this one turns out for you.
Title: Re: bamboo self bow build

If you get this to work right with those tips stiff enough, you may well build the fastest self bow in the world with no hope of ever beating it.

Very cool.  Clay Hayes did a video a year or two ago where he went to a tropical island, made a bamboo self bow with a snake plant fiber string, killed a pig with it, and cooked it in a primitive bamboo pressure cooker!   ;D

So yeah, I guess it can work.  Yours looks a lot prettier than his.

Thanks Willie.  Ya the handle section is 10” long and mirrors the limbs width at widest part which is 2 1/4” wide.  The bow is closer to 58.5” long ntn. The splice was 3.5” z splice. This I my second time doing this with bamboo and the first one didn’t explode so I hope this one survives.  I had pretillered the limbs prior to glue up so it should be close.  I’m guess and hoping at least 50lbs at 28”.  It’s basically a very wide pyramid type I guess. It may yet be the most crazy interesting bow for me yet if it survives.

Thanks Kevin.  Ya I’m hoping so!  If I can get it to be at 50lbs or just over that would be awesome.   Right now at brace it’s feeling like around 50-55.  This is purely based on my going by feel from build many of these.  We shall see.  I will only shoot this bow a few times here to speed test and keep my fingers crossed.

Very cool bow, David. Interesting build along.
 I've seen other bamboo self bows but they had the power fibers(outside) as the belly but I can see how the hollow belly style works for your bow.  :OK

A update on the bamboo self bow and a few more progress pics.  I got the handle sanded up and put a coat of tung oil on it to seal it a bit.  Ill add more later. the handle is made up of bloodwood, black walnut and black palm.   i also added thin horn plates for string groove nocks at the tips.  Ive had the string bite in and come close to splitting the bamboo on previous builds.  thanks for following along.

Title: Re: bamboo self bow build
Post by: sleek on January 30, 2026, 03:17:26 pm
Im looking forward to chronograph tests. The critical arrow weights to test are 450 grains and between 150 to 170 gr.  I have high hopes for this bow, especially in broadhead. Flight may prove difficult due to the longer draw length. Short stiff arrows do better than longer ones due to spine and weight.

Post by: superdav95 on January 30, 2026, 04:58:32 pm
Thanks guys!   I’m hoping to get a string made this week if I can sort it out.  I’ve got some flax linen I’ll try first and if that fails I’ll used a sinew material string used for old tennis rackets.  I’ve heard of good results with those.  I’ll make a b55 string for now to do some testing but will need to get on the arrows like you say Kevin.  I’ve got some 29” shafts ready to get at those weights.  I plan to barrel round the mid section of the arrows.  I’ve got a few to replicate from Arvin so here’s hoping I can figure it out.  Thanks again guys for all the input.

hey guys. i got it to brace and holy cow this thing is way heavier then i anticipated.  I had pre tillered both the limbs using my bench vice tiller set up before glue up so i knew that the bend would be close but its closer to 60-70lbs.  plucking the string it sounds like a piano string for cryin out loud!  The bend looks good and well balanced at this brace so i guess thats good.   anyway here are some brace pics at low brace of 5.25" from belly.  I want at least 6-6.25" Ill try posting a video too if i can get it to work.  Ive got some reduction to do which isnt all bad i guess.  Ill keep yall posted.

Dave are the ends working at all know? I know you are more familiar with what you are doing but I would try parallel for 8-9” then straight taper to the tips. That’s assuming the bamboo is thick enough on the ends. But make all but the last three inches not bend. But that’s me . IM watching and learning. Like it  so far!

You must be in my head Arvin. I just did that!  Anyway this makes me feel better the get the outers moving a little more.  These bows tend to have more of a circular tiller.  This also should lighten it up a bit too.  Good call!   I’ll post a few pics of it when closer to 55lbs.

How are you reducing this? I assume you will need to take some thickness off to drop that much weight. How do you do that with the bamboo limbs, as in what tool(s) are you using?

Mark

I’m just using rasps and sandpaper and block.  I firstly reduced width about an 1/8th” on each side of limb approximately midway up the limb then tapered slightly to the tips.  I also reduced thickness a little at a time and reassessed the effect at brace.  I pull a tiny bit to work in the changes and continue.  That’s it till I get close to 55lbs.  I’m getting closer now.  It better than the alternative I guess.  Not having the reserve draw weight to play with.   We shall see how it goes. It will be a crap shoot to some degree as I don’t want to full draw this bow yet till I get to the flats.  But I should have a good indication on draw curve when I get closer to target draw.  I’ll pull it to around 25-26” and then predict from there based on how my draw curve looks to forecast my 28” draw as close to 50lbs. 
Title: Re: bamboo self bow build
Post by: Selfbowman on January 31, 2026, 07:21:21 pm
Dave we have to weigh the bow at desired draw weight and length. So you can guess the intended draw weight and use a shorter or longer arrow or retiller there which is a pain. I usually get them to full draw and not shoot them till I get there. Everyone does it differently.

Well can’t argue with that advise.  You would know the best way to do this.  I’ll get it to 27” draw and make sure I’m at 50#.  That way if I loose a pound or two I can draw to 28”.  I hear a shorter arrow is best so if I can make some 29” barrel tapered shafts and pick out the stiffest ones I can play the odds.  I may not bother speed testing it here then I guess. I’m guessing I want to save any stresses on it for the flight shoot.  It does show promise now and the bend look good with lots of early string tension.  Just gotta get little more weight off and get my outers moving a tiny bit more.  It’s coming along but I’m taking it slowly.  I got one shot at this!   Thanks for the advise partner.  We shall see.

Ya I’ve been meaning to get there the 2 years but life got it the way.   The salt flats flight shoot is an annual thing for folks to go and distance shoot there bows.  There are various categories.  I’m sure if you google info will come up and the rules and such.  Keven and Arvin are a couple of guys that go regularly from here.  I’m sure there are others too.  I planned to take this bow along with others for different categories to test there and hopefully compete.

Ok so quick update on this bow.  After much sanding scraping and working in the changes I got it to 39 pounds at 20” and the bend was still looking good.  Prior to this reduction it was around 52 lbs at 20”!  All looked good so I decided to take it to 26” and get as close to 50lbs but then I heard a tic!!! My reader was at 49lbs just prior to 26”.   I immediately noticed a small crack in the handle on the mating surface to the top boo limb. It appears to follow a weird grain on the bloodwood. I didn’t notice this waving grain when I selected my blocks for the handle but when shaping it up they appeared.  I just figured it’s plenty thick and strong so should be fine.  Nope!  Anyway all is not lost as no damage to the limbs and my z splice still is good. The crack is due to the wavy grain I believe. The bottom limb looks good still.  I may soak some liquid resin down in the crack and clamp it down to cure. I will definitely be wrapping them when it’s all glued up again.  I think it was Simk that was saying how resin the acrylic stuff might be better to do repairs like this.  Any insights??? I was feeling very good about how it was looking up to this point and I’m just glad it happened here prior to the flats.   If my estimation is in line for a fast 50lbs at 27” or just a pound of two over that.  it is still a tiny bit heavy at approx 2lbs per inch which is what I was noticing after 18”.  So if I’m correct it’s targeted to be around 52-54lbs at 27”.  I may just be alright if I can wrap it after the repair.  I’ll try and post some pics in a day or so of the crack.  I’m not near the laptop at the moment. I’ll post some updates after the repair too. Thanks for all the support and help fellas.

Oh wow. I guess I’ve gotten lucky up till now then. I’m wondering if I should swap out this bloodwood some desert ironwood or teak.  I’m wondering now if I should just redo it now and be more sure.  I’ll have to see what I’ve got after the move.  Thanks for the heads up badger.

I'd be very tempted to bind the dips, to stop cracking or lifting. A lot of stress at this point especially with such a relatively shallow limb.
Title: Re: bamboo self bow build
Post by: Selfbowman on February 02, 2026, 11:42:14 am
I would start over with the riser you have to much time  in the limbs at this point and it looks hopeful for a good flight bow. Did you do some force draws as you went? Has the early draw changed much from24-26”? If you need some good Osage for riser wood let me know. I have lots of belly drops off my longbow builds.

I had used Massaranduba for bellywood and it is very good (not as good as ipe but nearby).

Massaranduba is often called Bloodwood!?

Yes hamish.  I’m for sure gonna do the wraps.  I have to get my head around that this isn’t a beauty contest and she is build for distance.  I’ve got some teak I think I’ll try instead.

I’m gonna rebuild the handle with teak.  I’ve got some here that I purchased from lumber yard while back.  Glad I didn’t get rid of it before the move!  I have some ipe too but don’t want to waste it on this.   I didn’t get to doing the force draw curve yet as I was merely trying to get closer to my target first.  But it was looking good and consistent.  I’ll do one when I get back to where I left off and write down some numbers.  I’ll try this teak first and let you know how she goes.  😎

Ya I’m not sure what variety it is.  I bought this plank from a local lumber yard and it looked cool.  Written on the end grain was “bloodwood”.  I actually wonder if this is paduak mislabeled.  The rack that I got this from had many varieties stacked together.  The give away for me is the smell of paduak when it’s cut.  It’s very distinctive smell.  When cutting this plank it reminded me of paduak.  I think it may in fact be mislabeled bloodwood. Unless bloodwood is another name for paduak.   Anyway it’s pretty stuff but not good for strength apparently.

Chumash. Massaranduba is an excellent bow wood, like you mention just a touch under Ipe. I've never heard of it being called Bloodwood. Personally never used any Bloodwood, because it doesn't have the greatest reputation for compression fractures.

Historically Massa' has been known and both beefwood, and bulletwood.

Bloodwood has the nastiest saw dust. It makes me sick. For a couple of days anytime I worked with it.

I'm from Germany and the common names are a bit different. Old names bloodwood, bulletwood, beefwood often declare a lot sort of woods.....

@badger
The dust of Massaranduba smells like some sort of pepper and I always have a burning in the noose, when I work with.

Hey guys a little update on this bow.  I got back to where to where I was prior to the mishap.  I did some sanding and more sanding then more sanding.  Trying to creep up on this 50pound target.  After a number of sessions of removal I am close to my target.  I figure a few more sanding sessions and I’m there.  It’s currently at 51lbs at 25”.  I want it at 50lbs at 26”.  It has maintained its 3” reflex and is holding it.  That’s a good sign.  I did a crude force draw curve as it currently sits.  Got good early draw.  I’ll post a link and hosted pics.   More to come.

Dave that force draw is impressive. A 26” draw  will put you using a 24” flight arrow with a 2” shelf. If you make 12-14# at 10” you have the bow to brake records. Now just get a arrow to come out clean and you are there. This a opinion from someone who has broadhead records but no flight records.  Good luck with your project!!!

ok so a few more sanding seesions and we are there!  50lbs at 26".  draw curve would essentially be the same as I was only a pound or two off.  I burnished the belly and edges well and may spray it to seal it.  You can see from the pics here that i was fortunate to not loose much of the reflex.  You can see the fairly dark cook on the belly too.  the dimensions have remained the same really its just more tapered to reduce weight in draw.  ill keep the cordage wraps on till after i shoot it at the flats.  Its got decent early tension and draw curve so we shall see.  thanks for looking

Dave how much are tips behind the handle now and check after tiller complete. This will tell everyone just how good you are. Just saying.

lol,,, Ya i got lucky with this one it almost didnt make it!  i just remeasured it and its around 3.25".  it must have crept over the last day or so of me reducing it down??? not sure but its been consistently 3".  Im gonna say the tips are 3" past the handle.  It really hasn't taken any set yet that i can see.  I figure the reason may be due to my being very deliberate on removal with sanding and then rechecking it. 
As I closed in on it i switched to 220 paper and got it.

   There might be more significance to this bow that it appears on the surface. I really have never seen a bamboo bow perform at a high level. I know they have been building bamboo bows for centuries but I just have never seen one perform at a high level with my own eyes. If this one performs the way it looks like it will it is opening up the doors to a whole new category of bow building. Bamboo is relatively cheap and easy to work. Looking forward to seeing what the future will bring.

Thanks badger!
I’m trying to curb my excitement about this bow a bit as it often can set us up for disappointment.  I’ve done a lot of testing on these bows and others like it using just bamboo as the working limbs.  The 5 piece builds were very good performers despite its limitations with glued siyahs and mass issues.  Despite all this they performed good and was attributable to the limbs and the heat treatment.  These recurve versions don’t have those same drawbacks or issues. Especially with having less mass out towards the tips.  The incorporated tips were just what it needed.  After much testing and breaking and fails I managed to get a few sets successfully recurved.  Green bamboo is great for bending in recurves but very hard to get in my neck of woods.  The other challenge with green for me even if on the odd time I could get some was drying time.  It takes a very long time to dry properly without cracking excessively. This cannot be hurried too fast or else more cracks.  Finding a way to get the recurves on dried moso slats was in order.  My first attempt was a nice little 30lb bow.  This prompted me to keep going and shoot for a 50lb set.  It’s been a journey for sure to get this bow to this point. We shall see if it performs the way I suspect it will.  I’m working on a some arrows.  My home made spine tester is mia but I still have my digital depth guage so I’ll just make another I guess.  I need good arrows to see good flight.  I’ve had more then a few of you guys tell me this so I better not screw this up.  lol.   😁

  I played around with bamboo bows just a bit now and then. Like you, I did the 5 pc with Syhas. I had often wondered whether pressure cooking might make them more bendable, but a large high-pressure cooker isn't really a practical solution. Harvesting and bending when green is a practical solution.

Congrats Dave!   :OK  It will be too cool to see how this bow does at the Flats.   (SH)

Yes I wonder.  If only I had access to unlimited green bamboo.  We will be heading to Panama next month too bad I can’t bring some home with me.  They have it everywhere down there.  They also have Osage!  I’ve got a buddy who lives and works down there that has a pile of it down and waiting for me when I go down next.    I posted a video a while back on how I did the recurves using very dry seasoned bamboo.  No secrets here.  I used Saran Wrap as I boiled them after soaking them tip down for 3 days.  I used a home made veritas type metal band  attachment to a handle of wood as I placed the boiled slats in for bending.  Seemed to work.  I kept the Saran Wrap on till it cooled and then removed it to breath.  Left on for a bit till dry.  I have two identical jigs to get both limbs done.  The Saran Wrap is the secret to get them to hold the moisture while bending.  Otherwise it drys out too quickly and cracks almost instantly.  Anyway I’m sure the video does a better job explaining it.  It would be a year or two ago that I posted it for those interested.

Hey Dave,

I could not find the video for the bamboo recurve bending using saran wrap. However, I found the folding takedown video. I really like that it seems super smooth. what kind of hinge and locking mechanism did you use?

Anyways, great stuff. Thanks for sharing!

Robert

Thanks Robert.  Ya I couldn’t find it either using the search feature.  I’ll dig it up and post a link here.  The hinge part for the folder bow is rawhide that I processed a few years ago.  It’s was a thick section around the d the neck that was little thicker so was good for this purpose.
