Was hoping to put the bow snot to this today but the glass is not here yet. The riser is Dymondwood Cocobolo. Its just rough sawn will finish the fades when the glass gets here and do the final dry runs. Hate to bump it and ruin an edge on a fade. Shooting for a draw weight of 51-53# finished.

Also a picture of the 2nd to last bow that came out of this form that my Dad built 60A-12, its a 60" 36#@28". This bow was built around 1969 and its traveled all over with me. Shot my first deer with it in 1977

Looking forward to seeing this as it comes together.

From: FITTER

Like the looks of the old one and look forward to the new one.... nice looking design :)

From: fdp
Date: 09-Dec-18




I really like the profile of that bow. Is that basically the same geometry as the takedown?

From: Oldbowyer
Date: 09-Dec-18




The 60A-12 is what I copied to build my T/D's in 1988. So yes its the exact same geometry as my T/D's

From: crookedstix
Date: 09-Dec-18




Todd,

How long ago did your dad come up with that design? Those are some pretty amazing hooks--can't wait to see how they chuck an arrow!

From: Oldbowyer
Date: 09-Dec-18




Well Kerry the best answer I have is I don't know. I've seen some of his early short bows with Pantherglass that had these hooks. At one time Dad had 4 of his 54" bows on the kitchen table one of the very first and one of the very last. The evolution of the design was very evident in the riser heights/design but limbs were close to the same. If I'm saying this right the reflex of the risers kept changing.

If that one bow shows up it is the very earliest 60" that I can figure out from the prefix markings in his book. They have no rhyme or reason LOL. There are 3 different designs LX. MX. and the 60A. If the other bow shows up I'll post the 2 together but the 1 I'm building is a 60A. The last model

OK this is the dry run on 60A-14. Glass will black with maple cores. Was hoping to use my Dads original cores for this bow. Unfortunately after over an hour going through them I did not have any that were thick enough. So I had to use a pair of Superflex cores along with a pair of his cores. Is what it is, I'm not a big fan of superflex.

Tomorrow will be for all the marbles, the bow snot will be going on. Will post a shot when it comes out. I'll start another thread when its done

Y'all take care, OB

What is Superflex made of?

From: Oldbowyer
Date: 15-Dec-18




Superflex Actionwood. This is the old stuff before the original plant burned down. It's a laminated maple product. The sheets were about .070 and then glued together to get the thickness. It comes dyed also. You can still get this stuff from any boywer's supply but it is made by a different company now. Its heavier than plain maple cores but it is a very consistent material for hitting draw weights.

That Dymondwood riser still has quiet a bit of "heft" to it! LOL

From: MStyles
Date: 16-Dec-18




Interesting.

I agree Todd-- that coco Dymondwood is heavy stuff. The Savora in the bottom of this photo was made of it...and it was heavier than the Spitfire in the photo, despite looking much lighter. The Spitfire even had a good amount of phenolic in the riser, and weighed 2.52#, but the Savora weighed 2.56#.

From: Oldbowyer
Date: 16-Dec-18




Well she's laid up but decided to leave it in the form tonight. Will break it loose tomorrow. Was afraid to run my heat guns at full on Dads old form. So I ran them on low for 5hrs at about 100*. Left over glue in bowl that I put in the box was well cured but it ain't going to hurt nothing to leave it overnight.

Will post the rough bow tomorrow, OB

From: Oldbowyer
Date: 16-Dec-18




Must have cross posted LOL.

That is a hell of a difference. This stuff I'm using is the new stuff. The veneers are thinner than the bow you have posted. The rough riser on this bow is heavier than Dads old bow also. That riser is Brazilian Rosewood.

So how does the Savora cast?

From: crookedstix
Date: 17-Dec-18




It was nothing special for cast. At my draw it was almost 59#, and it would only cast cedars 197-201 yd. on average. I had a 50# Drake that could out-cast it. As I recall it had Actionwood limb cores...and I think straight maple cores are faster than Actionwood, based on the bows I've owned.

But, it was a very sweet-shooting bow; quiet and accurate for me. I was all set to take it elk hunting to Colorado two years ago...but then I got the Tice & Watts, and I liked that even more.

OK She's out of the form. Made a couple rookie mistakes but she'll be fine. Still not use to laying up 1pc recurves it was 3yrs ago I built those 54's out of Dads other form and I forgot a couple things LOL. Flexing her this evening I'm in the ball park for the weight I'm after

What is that you are using for pressure strips?

This is an interesting design. On pin and needles following.

From: crookedstix
Date: 18-Dec-18




I can see one of your mistakes plain as day--there's no empty beer cans on those shelves in the background! A thirsty man can't make a proper bow, LOL.

From: 4nolz@work

would love to see closeups of the fades when bowsnot is sanded off

From: Bobmeister
Date: 18-Dec-18




Looking good Todd, can't wait to see a string on it. I have the same color wood going in a build I'm doing, good choice :>)

From: JustinB
Date: 18-Dec-18




Do you always rough saw your risers before glue-up? I love the sentimental value each bow has for you. Really neat. Thanks for posting.

From: Oldbowyer
Date: 18-Dec-18




The pressure pads are made of 1/4" rubber. They start at 2" wide and get narrower with each strip. There are 4 of them glued together to form the pad, Sorry about the pins and needles,

Trying to clean up my act crooked. Besides you will never see a can of beer on my bench unless my buddy left it. I'm a bottle baby.

Good to hear from you Bob been awhile. Thinking about getting a couple full blocks of this in Coco and maybe that 2 tone brown for some ILF risers. Sorry 4nolz@work my cheap camera won't take a good photo of the fades.

Thanks JustinB. Yes I always rough saw my risers. When you hit the glass with your bandsaw blade it ruins it in a heart beat. You'll never get through the riser with it especially when your sawing over 4" thick

Thanks for the questions and comments! OB

From: Bobmeister
Date: 18-Dec-18




Hurry up and get string on that thing will you.........

From: Oldbowyer
Date: 18-Dec-18




Damn Bob your as bad as a couple Europeans wanting to see this bow strung up. tell you like I told them. I'm old, I work at a sweat shop 6 days a week and I'm doing the best I can! LMAO

Take care my friend! OB

Things been slow but I do have her strung up today. I missed my target weight by 3 pounds but was informed its on the money, She's a little bit bottom limb heavy but hoping to hold the bow at 49#@28". Mass weight of the bow at the moment is 3.42# LOL Current draw weight is 49.6@28" 55.1#@30". Some shots of her braced, 28" and 30" draw

Great looking bow. with those big hooks I would bet it shoots fast.I would like to see some chrony numbers.

From: Oldbowyer
Date: 24-Dec-18




She's fast Bassman. I'll have to PM you the chrony numbers. The fellow who is going to play with the bow when its finished asked me not to post the speed. Least wise if I can shoot it. Not sure my shoulders are up to this much bow anymore. But I do have a make shift shooter than I can put it in if need be

Niiiice work Todd :-) JF

From: crookedstix

Ahhh, now I see why it's so easy for you to get your draw force curves! That's a slick setup you've got on the wall there--I especially like the trailer winch!

From: Dao

yep... verray beaauuutiful! :)

From: Oldbowyer
Date: 25-Dec-18




I use to use Dads "rusty old hay scales" and a yard stick caught a rash of chit from some of the pros I talk with on my DFC's. Sooo I bought the digitals and built the tiller stick behind it. use to have a buddy help me with my DFC's till he moved away so I bought the winch. It works well and no more hassles LOL. I'll do a DFC on this bow when it done to 28-30" be interesting at 30". Will do a DFC on Dads older bow while I have it also for a comparison of the two

From: fdp
Date: 25-Dec-18




Very good looking bow.

From: crookedstix
Date: 25-Dec-18




It's very interesting to see how much the tips are already working even when it's first braced--they open up right from the get-go. That must be where that high brace tension you talk about comes from?

From: Oldbowyer
Date: 25-Dec-18




Nope! LOL. But that's what its doing to those fast tapers

From: Pointer
Date: 25-Dec-18




Looks Great

From: Longcruise
Date: 25-Dec-18




Looking very good! The string angle at 30" looks amenable to a good DFC. I need to build one of those draw thingies. Would be a good tillering tool too.

From: 4nolz@work
Date: 25-Dec-18




My short recurve was opening like that and I took Sixbys advice and started adding 6" of bamboo on the belly at the tips to stiffen them and it helped alot with limb mechanics.

From: Oldbowyer
Date: 25-Dec-18




Did you compare the DFC's of the bows 4nolz@work. How short was it? Sixbys advice turned the bow into a static. Which ain't a bad thing. I've done the same thing with a taper change with out the added weight of the tip insert. More than one way to skin a cat LOL

There is an end game to this bow. The build is as close to what my Dad would have built. Other than that damn superflex core. Its a full working recurve that was designed as early as 1958. this one is out of a form of his from the 60's. It has some changes from the earlier bow. I'll probably end up eating some crow when this is over. But that's OK. Think Pop was on the right track. Just close minded to what he was doing. We'll see

From: 4nolz@work
Date: 25-Dec-18




Not a static just stiffened it some a parallel of .030 added after the glueup.

I've always heard bows that work mostly at the tips cast light arrows best I wonder how it would do at 6-7 gpp.Neat stuff He was trying supercurves way ahead of his time

From: crookedstix
Date: 26-Dec-18




You have any Turkish blood in the family, Todd? I think those guys were also into supercurves a bit ahead of their time. ;-)

From: Oldbowyer
Date: 26-Dec-18




Well I've been over 250 fps with an ace and 55# "hookin her a little"! LOL

From: Oldbowyer
Date: 26-Dec-18




I done that with my 64" in front of a crowd at a the 2nd leg of an IBO triple crown event. Shot twice with a friends ACE. Both shots were 251fps.

Just about there. Have a little more tip work and some details to put on the bow and its ready for finish tomorrow. I wetted down the Dymondwood just to get an idea of what its going to look like finished. Has a very nice Coco look to it and the beauty of this stuff it won't darken with age like the real stuff. Be using more of this Dymondwood in the future.

Y'all have a happy and safe New Year

From: crookedstix
Date: 31-Dec-18




Do you have a final bow weight and draw weight on that one yet?

From: Oldbowyer
Date: 31-Dec-18




Yeah Crooked I do. But saving that for the final post when the bow is done and run the DFC's on it. I'm betting at 30" she'll store over 100% ;)

From: 4nolz@work
Date: 31-Dec-18




>100% :)

From: mparker762
Date: 31-Dec-18




> over 100% That seems exceedingly unlikely. If it does, you should patent it asap, you'll make more money than zuckerberg.

Great looking Todd. Happy New year buddy :-) JF

From: Oldbowyer
Date: 01-Jan-19




LOL I see I have some skeptics. I get her done we'll see how close it comes to it. Its not all that unusual for a good recureve to be able to store that much at 30" of draw. I have a little static I built years ago that stores a little over 100%@30". But the design has its problems so I never pursued it.

Seen a force curve of a flight bow a couple years ago, It stored 114% and the damn thing was an Osage self bow. The bow is in Trad Archers. You'll have to root around to find it. I think it is in the "what are you working on now" thread should be in the middle of that some where.

From: Rigs Compton's Traditional Bowhunters

That's a very cool looking bow!

Cannot wait to see her finished.

Well Jason here you go. 4 coats of Thunderbird poly. Figured this bow would not be complete either with out my Dads decals on it. They are getting old and brittle I went through 6 of them before I could get one on the bow.

Well mparker762 pulled a DFC of another one of my bows today its posted on another thread. At 30" of draw its at 104%. At 28" its at 97%. Now I in no way believe that a bow can deliver more energy than its poundage. But it is more than possible to store it. All a DFC can do is show how efficient a bow can store energy. has nothing to do with what it will deliver.

From: Oldbowyer

Thanks anyway 4nolz. This bow is probably the last one that will come out of the forms as dad would have built it. I "think" what I done on that ILF will translate to this shorter bow, Should be a much better limb. So basically the Kid is taking over. Won't be the same bow anymore.

From: Dry Bones
Date: 02-Jan-19




The bow looks really good and apparently you still have some more playing to do. :D WHAT'S THE DRAW WEIGHT??

Well Dry Bones I'll post all of it when I can do my final testing on the bow. Hoping its enough to kill a Drake
