I have been working on a yew bow,reflex/deflex and need some one to look and see what yall thing,never tillered many of these and having trouble knowing what to do next. Looks good to me but just want some eyes on it that have done some.
1st picture is un braced,2nd is braced,3rd is out to 8 inches or so,at full brace and the last is 44@18 inches. What you thing,it is a little over 13/8 inch wide to about mid limb,the tapered to the tips, I used everything I could but it was a really rough stave with lots of side checks to deal with,nothing taken off the back but the bark and sanded,the ratio in sap and heart looked very good to me,of course I ant a yew guy. ;) Help and criticism welcome. ;) :) Shooting for 50@ 26 it has lots of reflex left and unbelievable early draw weight. Easy to be tricked. The reflex
tips are about 2 inches behind the handle and started with about 3 or so.That was right after un stringing after working it to 18 in. a bunch. :)

Not done myself either, so I can't offer any real advice!
But she looks good to me :), I shall watch with interest.

Looks nice Pappy.

Nice looking bow Pappy. How long is it and did you heat it to that shape or did it already have that basic shape? Reason I ask is I have a mulberry stave that that naturally seasoned close to the same shape and was thinking of heating it just enough to match the limbs up closer.
-
It's 60 n-n ,it had natural deflex in the handle area,I put the reflex in and flipped up the tips,it was going to be a bend in the handle because of the wood I had to work with but it seems to be enough to not bend unless someone tells me it needs to. It may flex slightly at full draw when I get to there and that is why I glued up the leather strips on the handle area. Come on some of you reflex deflex guys chime in,in my eyes it's looking good,just not sure where to go from here,more mid limb /fads or get the tips and curves moving more. :-\ Like I said it's 44@18 so I have 8 more inches to go. ;) :)
Pappy
-
I think it's working very hard right in the handle.
-
I agree with Adam. Also the left reflex looks like it could open up a little more.
I have trouble reading tiller with R/D bows so you might want to wait for more experience.
-
Sorry Pappy
I have no clue the finished ones all ways look wrong to me . They look this this > to me at full draw
If they dont help you out you might try the old trick of a pencil line on the sides to see how much bend you are actuality getting and just keep it all in perspective
Have fun

Cool thanks,I will get the mid limb from a few inches from the fads to the reflex moving a bit and the work on the left opening some,their is a big hump/kind of knot in the left reflex so kind of hard for me to tell. Thanks again. :)I know a few I have seen as of late looked at full draw like they were working to much in the fad area ,wasn't sure but didn't think I wanted that. ;)
Pappy
-
All the leverage from the limbs is concentrated at the fades and with the deflex already there it isn't hard to over do it there. From the few R/Ds I have worked on(and was successful with ;D ) I started working from the reflex back towards the fades as I tillered.
-
You are in what I call the death zone on these bows. It looks pretty good but where do you go for more bend? Be real careful in that reflexed area about 12 to 14" from the tips. It can be looking good and then kind of break loose and hinge while excersizing. I agree with Adam also, I recomend only advancing 1" at a time with plenty of pulls between each one.
-
Thanks Pat, I will try it that way,I just was afraid I would get the reflexed ends opening to fast so I have went very slow on them,but got to thinking it was about time to get them working more and wanted some advice, I have seen some sweet ones on here,no better place to ask advice in my opinion. ;) :) Now I am sucking up ant I. ;) ;D ;D
Pappy
-
Steve(Badger) knows more about these bows than me. ;) They can be very tricky to tiller.
-
Thanks Steve,must have been posting while you was. I had heard or read that before so that is why I have been going so slow,I have been working it a lot between scrapping and brace and un brace and even let it set a few times at brace for an hour or so,GaryDavis told me on my last Yew to go really slow and exercise it a lot,guess I got that part just never done a reflex/deflex. ;) :)

Pappy I am thinking the middle third and slightly into the outer third could bend a bit more. How wide is that bow? I starter going wider so I could leave about the last 12" pretty stiff, makes them easier to tiller.
-
Wish I could help Pappy. Unfortunately, I'm completely ignorant of r/d bows. I'll be watching this with interest! Josh
-
See if you can scare up DVSHunter's attention. Dave's an R/D expert! :D :D :D :D :D

I make r/d bows all the time, Pappy. Stay away from the flares and out 6 inches all together. Get the areas I have circled bending more. Roy
-
My latest r/d bow, Pappy. This bow has already been tillered out, but before I started tillering it, it had almost as much reflex as your does. Notice at a brace, the outer 2/3rds of the limbs are sort of flat, then even at full draw they are still a little flat compared to what a straight limb bow would look like.. I guess we could call it an elliptical shape.
-
Your bows reflex, and my bows reflex before I tillered it. My bow does not have the riser section on it yet in the picture.
-
Here it is on the tree, it's only being pulled to 20 inches here. The outer 1/3rd of the limbs will come around even more as it's pulled down the tree to my draw of 28". But you can see how the reflex of the outer 3rd of the limbs begins to flatten out, that shows that the outer 3rd is working. Now I flip the tips on my bows before glue up, so the last say 9 inches of them will not come around, even at full draw. Please excuse the long gray haired hippie look.. :)

Thanks Roy,I like the look of yours at full draw,I thought that is what I was looking for,just wasn't sure how to get there. Steve it is about 1 3/8 .I wanted more but like I said it was a pretty rough stave and that is all I could get,I was afraid it was going to be a bit un stable but seem to be doing fine in that respect.
I will scrap a little in the next few day and see how it goes.Thanks for the responce. Any more advice welcome. :)
Pappy
-
Pappy, you must have a couple beers when tillering a bow. Otherwise it won't come out right.. :)
-
I think Roy nailed it pap. I can't wait to see how it turns out, I think it's gonna be a real nice shooter :)
-
That is looking pretty sweet.
-
I agree with the above all I can add is slowly slowly slowly ;)
Full draw will be interesting to see.
-
Look'n gooooood! can't wait to see how it turns out!
-
Looking very nice so far pappy. Can't wait to see it completed
-
Got it out to 47@20 1/2 last evening,worked on the areas mentioned,I would work them some and then most of the limb,except for the last 6 or 7 inches at the tip and the area close to the fads. I think it is coming around,yes Mike full draw should be interesting,the early draw weight feel better than anything I have worked with,may be the design or the Yew,not sure. ;)
Pappy

Pics??
-
Wish I had the skills to help ya out ::) a R/D yew selfbow sure would be a smooooooth sweet shooting rig...send that sucker my way when your done with it >:D ;D ...Pleeeeeeeease!!! With a sugar on top!!!!! 8)
-
I got it out to 50@22 yesterday evening, still holding 1 1/2 inches passed the tips and the brace tiller is even top and bottom all the way along the limbs. both top and bottom limb are 1/4 off the wood at flat before thenocks.I will get some pictures by the weekend,just taking it slow for now, everything seems to be looking good and all is even for now.also got new computer and really having trouble getting around.
Pictures may be a problem also haven't try doing that yet.I hate change. ;) :) :)
Pappy
-
Looking forward to seeing this one Pappy...I'm in your corner and pullin for ya...
-
Im sure you will do it justice Pappy. I like to have the reflexed part almost straighten out at full draw. Any more and they look nice but tend to loose performance and take set in that area.
-
Thanks Jesse,good to hear from you. ;) I got it out to 50@ 23 1/2 yesterday.Still I think looking good. Ran into a little problem,as I said to start the stave was in really bad shape with side checks and checks all through it,it hasn't seemed to cause any problems but yesterday while doing some light scrapping and sanding I got the sand papper under one on the side that runs to the belly,at least it's not to the back. ;D I stopped and glued it up and now am trying to decide weather to carry on a bit or wrap it now. :-\ If I can move on another inch or so I will not need anything off that spot anymore,I really don't want to wrap and then un wrap to scrape and so on. I think I will try and get ot about 25 and then wrap,at least that's my plan for now. Hope to have some pictures Monday.Still feels very snappy,lots of early draw weight and very little set so far. ;) :)

Anyone live close to Pappy that could stop by and show him how to use his new computer for loading and posting pictures? :)
-
Well I live right down the road but his computer he uses it at work. He's pretty savy though, I think he'll get it figured out ;)
-
I got a chance to take a pic if pappy shootin her in this afternoon. He's got her back to 24" or so right here. (http://i1035.photobucket.com/albums/a439/willharrison347/3171870E-5876-4FE0-AF6E-9B072BD92FDC_zpswdjbqbvq.jpg) (http://s1035.photobucket.com/user/willharrison347/media/3171870E-5876-4FE0-AF6E-9B072BD92FDC_zpswdjbqbvq.jpg.html)
I gotta say, that thing sure zips an arrow!
-
Looks like it is bending nice to me - only a few more inches to go!
-
I think Roy hit right on the head, the areas that he had circled need to bend more. It's a little difficult to get that bending and be careful it will go all at once.
Mark
-
know what about new computer im going through the same thing windows 8 is a nightmare to me.i think that's the first yew R & D selfbow ive seen no dought you will work it out cant wait to see finished .
-
Got it shooting out to 25,just a little more,it is 52@25 so I may take just a few more scrapes, man it seems fast and really smooth to draw,not really into mass princeable but weighted it anyway and it's at 19 ounces.got trouble down loading pictures this morning ,I hooked my camera up this morning and it said I had over 7000 pictures on it,got to figure out whats up. Pictures soon ,I hope. ;) :)
Pappy
-
I have a Yew flat bow I'm finishing up right now that a R/D profile .
-
Looking good, Pappy.
-
Looking good so far! Hoping to try one of these someday.
-
Looks great, Mark! Yew always gives me the heebie-jeebies. :laugh:
-
Can't wait to see that thing pappy.
-
Your getting close, Pappy. Looks real sweet..
-
and it said I had over 7000 pictures on it,got to figure out whats up. Pictures soon ,I hope. ;) :)
Pappy
Don't post all 7000!! >:D >:D
-
Pappy that design as well as the tiller shape you are getting does produce extremely fast bows. Once you finish you should have a local flight shoot on your property and kick all the young guys butts! Like Will for instance LOL>
-
Thanks Steve,it seems to be fast at 25 inches,not sure how much more I can get the
curves to bend with just another inch,they are bending but aren't going to flatten as some have said they need to. :-\ It is about 1/2 inch behind the handle after lots of shooting and staying braced for a couple of hours,then back to 1 1/2 after a very short rest. I think I am just going to take a few scrapes to reduce the weight a couple more pounds it is 53@25[little heavy for what I want] and call it good.I am shooting for high 40's to 50 @26. I have a knot in one of the curves and have been trying to keep them even and so far have ,it just don't want to move much through the knot and I am not sure I want it to. ;) :) I'm with you Matt,reminds me to much of ERC, I know it's not but it reminds me of it. ??? I have some really bad and exciting experience's wit ERC.

Looking good pappy. I wouldn't worry about getting the limbs to flatten out. If its not taking set and shooting fast you are good to go. I have had bows loose reflex if that area bends to much. Cant wait to see it all finished.
-
I agree with Jesse, don't worry about the bends straightening out, you have quite a bit of deflex in the handle and should easily make up for that.
-
That's my plan then,a few scrapes and another inch or so and call it good,shoot the crap out of it and then if all goes good, doll it up a bit. :) Thanks for all the input. Much appreciated. ;) :)
Pappy
-
Well I think I about have it, I may take a few more scraps to reduce the weight a couple more pounds but other than that I think it is ready for dolling up,let me know what yall think. 1st picture is the shelf I added,Goff T,seems to work great.
2nd is at brace,3rd is un braced 4th is at 25 inch draw and last is at 26 inch draw.
It is 53@26 ,maybe a little much for me, very fast and very smooth,no shock,just want to scrap the right place so if it needs anything it's now or never. ??? Advice please. ;) :)
Pappy
-
Looking real nice Pappy, amazing how much power those long levers generate.
-
If you want to shave off a few more pounds, I would scrape the two areas I have circled. Looking nice, Pappy.
-
Thanks Roy,and yes Steve it is really a snappy little bow. :)
Pappy
-
Looks great pappy! I agree with roy. It wouldnt hurt to take a little from where he marked.
-
Thanks,That's my plan then,a few there and then a few full length and call it good,thanks. I am ready to finish this thing up. ??? I am fixing to get really busy in the next month or 2, so I need to get this thing done. ;) ;D ;D Thanks for the input from all. :)
Pappy
-
I'll be sure to see that in person at the Classic and can't wait to see the finished pics.
-
I have looked at this thread for a little while now and I gotta say you and Roy have some really sweet looking R/D bows. the profiles are just too curvy to not love! cant wait to see the final results
-
Looks like it's getting darn close to dolling up time! Good work Pappy
-
Thanks Guys,didn't have much time to work on it this weekend but did get a chance to knock a couple or 3 lbs.off and shoot it some,it is 50@26 and I'm leaving it be,seems everything is even,1/8 pos.tiller on the top limb so I plane on shooting it a few days and finishing it up. ;) Got a long weekend coming up so inbetween Turkeys I should get time to get some finish on it and maybe a grip.Thanks for all the input, been very helpful. I think I am going to like this thing. ;) :)
