Paka looks like a challenging stave im interested in seein this one born

Well got out the block plane and rasp last nite , and tried taking it down to flloor tillering size weight . For anyone gettig started, I've bein using a machete and rasp in the past for all these stages so far untill I got a $10 dollar block plane and what a difference it makes. Long even wood removal without alot of machete gauges . If anyones like me and starting off without many funds or wood working tool's , work with what you got and try to slowly add to your tool inventory. Plus , when you do get a new tool you'll really apprecaite it , and have all the memories off other techniques you have tried. Anyways here some pics

I'll put it up on the tree after a little more wood removal and I'll take any advice on tillering you all may have ;) . Till later Paka
-
...just take it slow and get it bending evenly from fades to tips... when I first started I went and looked at all the full draw pictures of other peoples bows I could find on the message board. Then just tried to get the same bend. :) Good luck!
-
looks good so far

heres progress tonight 1st pic long string hanging 13 inches . 2nd pic is at 19 inches at 35 lbs . 3rd pic is 20" at 40 pounds . I"m shooting for 27 " draw at 50 pounds. I'm gonna keep working on shaving down limbs for the right bends . Is my long string to long?? Should I long string to 27 inches at 50 lbs , then go to short string?? What do you all think? Any comments would be great ;) Paka

I give the bow a good floor tiller and brace it very early. The long string gives a wrong picture.
Be careful - a reflexed stave like yours often feels too strong so scraping too much wood and coming to a 30# is the result ::)
And yes - your long string is too long (for me) ;D
-
10/4 there buddy , I'll shorten the string ;)
-
Just remember to go slow and keep it bending evenly. Exercise it good between wood removal sessions. Gonna be a nice-un if you take your time with it. :)
-
Its 1.5 inches at widest points and am wondering if its safer to shave wood off the sides and leave more wood on belly , or just take wood off the belly and keep the width ??? I feel like I"ll probally do both in the end But am ruuning all I can by you all . Thanks Guys and Gals Paka
-
Aloha Woodbending Folks ;D ,
Well I shortened my long string to 5 inches of play before it pulls on limbs . Thats the 1st pic. Second pic is at 50# at 20 inches . Will keep shaving away . ;) Tommorow I'll go to short sting , then to brace hopefully in the future .Midnight here, time to crash . Paka
Actually the 1st pic is now the 2nd pic , n 2nd pic 1st ???

just remember not to go over your target weight. Remove some more wood and make it bend a little more so you can really see it, then get it to low brace.
-
getting there , bottom picc is with same 4 inch extra longstring at 50lbs at 21 " . Should I go to tillering string (4 inch tiller ) or a 1 inch tillering string?? Or keep long stringing till 26 inches and keep working on tips and around hinges??

that right limb has me worried a little. if it were me, i'd get the left limb bending the same amount or maybe even a hair more than the right, then scrape the right from midlimb out to the tips before i pulled it another inch. if you pull much more, you may end up with set in the right limb where it's starting to hinge now.
as far as the width vs thickness goes, i'd focus on thickness now & leave the thinning for later when you fine tune the tiller.
lookin good so far!

one of these days i will have GAUVA..LOL....JOHN
-
Here's what I would do at this point if it were mine. :) Try and get it bending evenly before going any futher. Good luck! :)

Awesome guys, just got home from a really long, hard day and that put a smile on my face. I admit I have alot to learn because I would of probally done the exact opposite of what you drew out Josh. Tank's for that detailed graphic picture . When can I go to a shorter string?? And will it be like a 4 inch brace???
-
Welp heres some progress I hope. Tried what you mentioned Josh and a little more. This shot is at 21" at 47 pounds . I'm hoping for a bow between 53 to 47 , am I on the right track?? The tillering string is snug to bow. What do you all think?? I had it at 50 pounds at 22 inches. Thanks all , Paka

Lookin good so far, I would still remove a little bit from mid-limb out on both limbs and your left limb is still a little stronger than the right, I would bring it to a low brace after you do that little bit of scraping I mentioned. I think this one is gonna turn out pretty good. :)
-
This tillering process is driving me Lolo (bonkers) ;) I only have time from 10:30 pm till 12:30 am to work on my bows so I'm pretty delirious now . Anyways I hope I'm getting somewhere. Did what you said Josh , exept Idont have a scraper , I'm still using a rasp so I will be sanding jus a little more than you all do but this is where it is now. She"s 30 lbs @ 18 ". 35 lbs @ 20 " , and I got to 40lbs @ 22 " tonight. The photo is at 21 inches. I figure at that pace at 27 inches she"ll be aroug 50 lbs after sanding I hope ??? Antways heres the photo, please keep the idea"s and recomendation"s coming. Thanks so much , Paka

Forgot photo ;D

Stay away from the fades--especially the right one.The left limb is still stronger... weaken the left limb from mid-limb out. :)
-
Have you braced it yet? now might be a good time to take it to a low brace of 2-3 inches... First brace will magnify any tillering flaws you couldn't see on the long string. As soon as you brace it, If it doesn't look right, unbrace it and scrape where it needs to be scraped, exercise it on the long string about 30 times, and then try bracing it again. Do this till it braces evenly then continue tillering it with it braced on the short string. Good luck, I think this one is going to turn out nice. :)
-
Will do Josh , thanks for the coaching , really appreciate it :D
-
Paka , I might chime in, Josh is right the right limb is hingeing on you. Take a small block of wood about 6 inches long and 1 inch wide. Screw a wood screw thru , just enough to scratch the wood it comes in touch with. We will call this a tillering gig. Now run your gig up and down the limbs and mark the area your gig scrapes with a pencil. You then will be able to see the area where you need to remove material. Use a old file or fat knife for a scraper till you get one.A pc of broken glass works too. Stay away from the hing area.work on the left limb till you get close. Then vocus on the area above the hinge area scraping a little towards the tip. fine tune till you get them bending equal. I give classes at my shop all the time and people run into this lotsa times. So you aren't alone. Be patient and scrape ,flex scrape, flex until the bow is revealed. If you go slow it will work. You probably will loose pounds at this stage, but , there are other options down the road. Good Luck Denny

OK guys, so braced it late last night at 3 " ???and really saw hinge on right limb fade and saw left was really stiff. I worked on the mid left limb to tip and still have more to go. My camera went down so I need to get that fixed ??? But I"m gonna catch up on some rest tonight, make that limb jig and continue on tommorow. I also ordered some B-50 , serving, and serving tool from 3 Rivers wich should be coming in soon . Thats a whole nother adventure coming ;) Thank's guys for all the tip's and advice , I really appreciate it all ;D Talk to you all latter . Paka

OK guy I'M back,
Got my string materials last week and learned how to make flemish strings, I've made 5 in the last week for all our bows. Me , wife , and 3 of my 4 kids. The bow was getting close to around 45 pounds at 28 inches so I stopped tillering. I"ll post some pics, jst fixed my camera. Ahh, baby fussy , talk later. Paka
-
Well got to ecxersise it a little and work on string tonight. Tomorrow I"ll increase barace a bit and try to get some full draw pics soon. I noticed my bottom limb is an inch shorter, is that common?? Or shood I try to make the the same length next time??
Am asking around for silk to back next bow , this is just cotton . Anyways , enjoy pics and will catch you all later. Paka
P.S. will also add handle work tonight .

can't wait
-
Looks a lot better paka. Yes lower limb should be a little stiffer. Denny
-
Well unfortunetly I think the lower limb is now weaker than th top limb , I took off just a little to much wood. I tell you what though , it sure shoots good. Will try to get the full draw pics taken soon . Gonna take it Friday to find some pigs ;)
-
Got to shoot it today at 20 yards and she does her job well. Was a blast. Heres the full draw pic , little uncomfortable in a small room but untill I can get outside it"ll do . I guess I took to much out of the bottom midlimb and not enough from top tip. Thats the complete opposite of where the bow was arlier on in this build ??? ;D . So its funky and I cant wait to build another and keep working on tillering , but if it puts meat on the table that will be unreal . Enjoy Paka
P.S. Thank"s Everone for all your help , Mahalo Nui Loa

you could always tiller it lighter and back to positive tiller and then glue on a thin lamination to the belly.
