Title: Boo backed Ipe (not for BOM)
Post by: Gordon on January 23, 2010, 08:34:07 pm
Here is a bow that I made for a gentleman on the east side of the Cascades. Its bamboo backed Ipe with Osage power and handle laminations. The tips overlays are African Blackwood. Limb dimensions are 1” wide at the fades tapering to a little under ½” at the tips.  The back is stained with black and brown leather dye. The bow is 68" ntn and draws 48# @ 28". The owner is new to archery and I wanted to make him a bow that would be easy to handle. So I made it a little long with a mild reflex/deflex profile. It holds about ½” of reflex at rest so it should be easy to string. The bow is stable and sends an arrow down-range with authority. I think he will like it and I hope you do.

Will you adopt me ????!!!! Maybe then I could learn to build bows that remotely resemble yours !! The fit and finish is always impeccable on your creations. They always provide tons of inspiration for me. I appreciate your posts - they show what CAN be achieved. This bow represents what I hope to someday achieve - world class.

Thank you Justin. I hope he does like it as I want to trade something for it.

Thank you Rp, but this bow is hardly a ferrari. But it's not a clunker either  :D

Thank you El, I really like the combination of osage and ipe.

Thank you Cooper. I agree, Ipe and bamboo are an excellent combination.

Thank you for the compliment Steve.

Thank you Dana.

Thank you Lombard.

What a nice compliment barebo, thank you!

Thank you woodstick!

Very nice Gordon! I like the color contrasts in your dye job, as well as the profle and tiller.  I am wondering what the draw weight and length are.  It looks a little longer than most of your bows, I'm guessing 68 in or so.

Thank you Gabe. I noticed I neglected to specify the draw weight and length. it is 68" ntn and draws 48# @ 28".

Thank you Josh.

Looks really nice Gordon. I like them long like that. I think you made the perfect bow for someone starting out because that length will make it more forgiving of shooting form and  also more forgiving of abuse. Im sure he'll be happy. I would be.

Glad you are having fun with crazy tropical wood Gordon. That is one of the prettiest I have seen..I think we will see a lot more osage and Ipe together on bows in the future ;D.

Did you steam bend the laminations, or bend it during glue up?

 Very nice Gordon, I'm sure he's going to be very pleased with it. Love the way that you did the osage power lam. It makes a very nice accent stripe. You sure are getting those laminate bows down and withthe Ipe I'msure it's a great shooter.  Let me know what how it fits Him. Any Idea when your coming over this way?

Thank you Frode.

Thank you Jesse. These longer bows do seem to be more forgiving when shot.

Thank you Rich. I am enjoying working with Ipe, though I have a shopful of yew boards that I need to start working through.

Thank you Don. I appreciate the compliment.

Thank you Barage.

Thank you NTD. I will consider your offer if the owner is not happy with it  :)

Thank you for your kind words Frank.

Thank you for the compliment Rick.

Thank you Pete. I think I'm finally beginning to get a feel for what an r/d profile should look like.

Thank you Saw Filer.

Thank you Goog. The refex was glued in on a form.

Thank you Keenan. I really hope he likes it. I expect I will be over in your area in the March time frame
I still need to make a self-bow for the Mrs. And I'm going to make some arrows so they have something to start with.

Thank you adb.

Thank you for the nice compliment John.

Thank you Jeff. The main reason for the power lam is to stiffen the handle area so the handle laminations won't work loose. A side benefit is that it creates a nice shape so I don't have to build up the front of the handle.

Dad gone Gordon, as always I follow your work and strive to mimic your level of detail.  Never reach it but one day.

How thick is your power lam in the middle?  How long is it compared to past the fades?

I guess your past your bamboo blues?
Title: Re: Boo backed Ipe
Post by: Gordon on January 24, 2010, 01:42:53 pm
bigcountry,

Thank you for the compliment. The powerlam is about 5/16" in thickness,  18" long and extends 4.5" beyond the fades.

I believe the reaons for the previous bamboo failures is related to the way in which I cured the bow after a glue-up (i.e. too much heat for too long). I won't know for sure, however, until I make a few more of these.
Title: Re: Boo backed Ipe (not for BOM)
Post by: Gordon on January 24, 2010, 02:14:48 pm
Well, I guess I was premature thinking I had my bamboo problems figured out. The backing failed as I was testing the bow on my tree this morning. Examining it closely I can't see any reason why it failed the way it did. But that's four in a row now. The only variable left is the bamboo itself. I'll discard what I have and order a new batch. And hopefully that will be the end of it. The only consolation is that I'm glad it failed now rather than later.
Title: Re: Boo backed Ipe (not for BOM)
Post by: Badger on January 24, 2010, 02:29:08 pm
   Gordon, I started making mine a bit wider, I had a bunch of failures as well. I make a 60# ipe boo about 1 1/2 at the fades now sometimes 1 3/8. That was a beautiful bow you made and tiller was perfect, as long as you keep the outer limb narrow you won't loose any spped, actually I think you gain some because it doesn't break down as much durring tillering. Stay with it, nothing wrong with your work, Steve
Title: Re: Boo backed Ipe (not for BOM)
Post by: Gordon on January 24, 2010, 02:35:01 pm
That seems like really good advice Steve. I think I will start making the limbs wider. That said, I'm still going to discard my existing cache of bamboo - I just don't have any confidence in it anymore.
Title: Re: Boo backed Ipe (not for BOM)
Post by: Cooper on January 24, 2010, 03:18:06 pm
Gordon, I am sorry to hear that. Did the bamboo break or removed it from the ipe?
Title: Re: Boo backed Ipe (not for BOM)
Post by: Gordon on January 24, 2010, 03:59:41 pm
The bamboo splintered along an edge. It's probably salvagable, but I can no longer give it to the intended owner.
Title: Re: Boo backed Ipe (not for BOM)
Post by: Justin Snyder on January 24, 2010, 04:04:19 pm
Man that really sucks. How far from the nodes did it fail? How rounded were the corners? How about some pictures of the failed boo. I don't know that we can figure it out, but it might be educational.

Don't throw away the boo, you might decide to use it as a belly piece where it wont fail under compression.
Title: Re: Boo backed Ipe (not for BOM)
Post by: Jesse on January 24, 2010, 04:15:58 pm
Strange. That bow certainly was built well from the looks of it.  ??? ??? I would get some new bamboo as well. Even though wider could be better 4 in a row is abnormal even if they were only an inch wide with a poor tiller. which they were not.

Sorry to hear it.  I feel responsible for some reason.  Shouldn't have mentioned it.

Title: Re: Boo backed Ipe (not for BOM)
Post by: Gordon on January 24, 2010, 04:34:13 pm
Justin, the splinter started just off the end of a power lam and stoped about an inch short of a node. The bamboo edges were trapped slightly and then smoothed so there were no sharp corners.  I'll post some pictures later.

Bigcountry, obviously you are not responsible but your timing is remarkable. You may want to go out and buy a lottery ticket today. :)

 Wow Gordon, sorry to hear that, That was a great looking bow.  I will second what Justin is saying, keep the bow for belly lams.  If the splinter is on the edge would it be possible to work that part out and make it a bow for a lady?
Title: Re: Boo backed Ipe (not for BOM)
Post by: adb on January 24, 2010, 08:33:41 pm
I really feel your pain, Gordon.  :'(  As I've mentioned before, bamboo is not in my arsenal of options anymore, for the very same reasons you're experiencing.

I figured you had it good, I just wanted to know exactly how you did it. I do it different than most.
I don't know what caused it for sure, but I have had similar issues with boo and hickory. It seems as though I had it bending well, then when I transitioned to non bending I think it was too abrupt of a change. It was like the boo was still trying to bend, but the belly didn't want to so it popped. I decided it was putting too much stress on the fulcrum point. Of course, just because I decided that was my problem doesn't make it so.  ;)
Title: Re: Boo backed Ipe (not for BOM)
Post by: Gordon on January 24, 2010, 09:42:53 pm
It's possible that's what happened Justin, but I'm careful to make the limbs bend through the powerlam transition right up to the fade.  Maybe there was a weak spot in the backing at the point of failure - I don't know.

Keenan, I think I'll grind off the backing and replace it with a strip of Tonkin bamboo. I hear that stuff is pretty tough. I hope so...

That is a gorgeous bow Gordon. I'm sorry to hear about the boo failure. I have had my run with bad luck here lately also. I'm doing the same thing you are and ordering some more boo... from a different source.

You would think.  I had a Tonkin backing fail on me a few years ago, the belly was IPE

Gordon I'm so sorry to hear about the failure!
It was such a beautiful bow!
Title: Re: Boo backed Ipe (not for BOM)
Post by: Gordon on January 28, 2010, 09:34:40 pm
After taking off the existing backing I no longer think it was the bamboo that failed. It appears to have been a glue failure. I had the limb clamped at that spot so maybe I had it too tight and starved the joint. At any rate I have a piece of Tonkin worked down and ready to glue on. Hopefully I can salvage this bow.
Title: Re: Boo backed Ipe (not for BOM)
Post by: NTD on January 28, 2010, 09:46:12 pm
I hope you can salvage it too.  What kind of glue did you use?
Title: Re: Boo backed Ipe (not for BOM)
Post by: Gordon on January 28, 2010, 09:49:35 pm
I used Urac. I never had a problem with Urac before, but upon close inspection I'm fairly certain the failure resulted from a delamination.
Title: Re: Boo backed Ipe (not for BOM)
Post by: NTD on January 28, 2010, 09:54:16 pm
Eww.  Sorry Gordon.  I've only done two laminates but have used TBIII.  Everytime shot them for the first few hundred shots I was paranoid about a delam explosion...
Title: Re: Boo backed Ipe (not for BOM)
Post by: Gordon on January 31, 2010, 11:43:02 pm
Got her tillered today. I'm pleased with how she's turning out. The new bamboo is holding fine and the bow doesn't lose a bit of reflex after shooting.  :) This tonkin is pretty good stuff. Next up is a week of torture testing. If she makes it through that intact, we're good.
