will it work or not all glass lamination bow limbs

[Loren Piper]

I just poured a inter lamination glass to take the place of wood tapers and par. We made them out of a special glass and tapered them like wood we put it in the press and oven this evening, we don't know if it will work but we used black S Glass on the outer and outer part of the limbs we are testing it on a take down bow'the S Glass is .040 thick which is stronger then the old E Glass,and gives a high arrow speed. has any one missed with this ?Let me hear some comments it may not work but again it may make a faster and better bow.

This will be interesting to see, but those solid glass bows of old had pretty thick limbs. My first guess is that it will bend like a noodle, but I'm not familiar with the type of glass you're using. Hey, if nobody experimented, nothing would ever get built!

[Loren Piper]

I have two out of the oven and rough cut to shape The limbs are 1 3/4 wide and a total thickness of .190 which should be about 35# I bolted them to a handle I made a long time ago and it isn't a 35# it is 45# at a 28 inch draw the toughness is unreal I am going to test it a lot more but I believe it acting great. I would like to send a few to people who are interested Like you Tom then you will have others testing it I believe  it is great so far if interested E Mail me and I will send you enough to make a bow you will have to taper your own We are useing a new resin in the building of the inters and it is stronger and stiffer then any that is on the market.

it'd be interesting to see the differences in s/g between wood and glass. As the outter lams take most of the strain, the core wouldn't really matter.

As I've read that full-glass bows tend to have more handshock, I guess glass is heavier then wood. And as it isn't really stiffer, it wouldn't add any speed to the core. The higher weight would actually slow it down.

just my $0.02 (actually, €0.02)

You need to shoot one of these mixures do you build bows? if so I will give you enough to build one free that is the inter core you can use what ever on the rest of the bow all I ask is to pay shipping cost I am very pleased and am still working on improveing it I think we can save a lot of trees with this Ha Ha.

[Trux Turning]

It should work- it will be interesting though to see if the s-glass outers you are using make up for the heavier core- or if the consistency of the core glass equals more performance/speed.

[Loren Piper]

The core is measured in once weight not thickness it is put under high presure and compressed when curing in oven we govern the stringht by how many onces is compressed,Trux if you build bows I will send you enough to make one bow, you pay shipping only and let us know what you think of this, You don't have to use our products to receive this offer.  WWW.lorenpiper.com

The free offer is good to all posters in this testing till we say no more. I realy want a feed back on this all pros,& cons so we can perfect it the wood in a glass bow don't do too much I have found,Bob Morrison is useing dense foam and he builds one of the fastest and finest custom bow on the market, he is keeping up to the new times in bow making.

[Tom Leemans]

Hey, if you want to send me one for testing, I got a wife and two daughters that would love to shoot the heck out of one. I'm a wood bow guy, but I also love R&D work. Designing and developing is fun, eh? My main concern is how the limbs would hold up. (Can you tell I'm a maintenance guy?)
PM me if you need my addy or something.

Mr. Piper
I've read your post on the bow you built using all glass. I build bows as a hobby and wouldn't mind giving your offer a try if you still are doing so. I build 1 and 3 piece bows. Here's a picture of the last bow I built for my grandson.

You would think it would feel like the old all glass bows. The ones that are molded that way, not laminated.

I Shot this test bow yesterday for over a hour no hand shock an very smooth I realy can't tell any bad efects at this point the wood arrow weight is 1oz and the length is 29 inches and it was shooting at full draw 28 inches at a 38# draw was going through at 124 feet per sec. the lembs show no change at all I have a Ben Pearson take down all fiberglass bow when you shoot it, it is like nite and day much smoother and faster.Don't take my word build one and try it.

[Tom Leemans]

Which one is smoother and faster? I would expect more than 124 fps from any 38# bow and a 480 gr. arrow though.

[Loren Piper]

The glass is smoother and faster

[Kevin Karnehm]

Well Piper just tell me where to send the money! I have had some issues with glass already. What you're talking about is a very interesting. I'm willing to give it a shot and give a full report!

Loren, can you post some pics of this all glass bow?

[Loren Piper]

I am trying to learn how to post pictures on this sight,but a old dog is hard to teach, I made a set of limbs and made them .110 on the core glass and used a E Glass of .050 on the outer and .040 on the belly Man that is a NO NO
this bow was 145# draw the Glass core is so much stronger thAn wood. This is on a T.D.Recurve so we are going to have to build  Another,less draw weight for this old man.That was at a 26 inch draw.the taper was .002 mY HELPER SHOT IT FOR SPEED at 22inch draw it shot 164 feet per sec. That is all he could pull.

Loren,

Would love to test your glass....I could crank out a hill bow...How much do I need to send you for shipping?

[ARCHER2]

Hey Loren,
I'd like to give this a whirl if you're still offering it. Let me know please.
                               Thanks!

Posting some pictures for Mr. Piper and and explanation of the pictures.
   

This is a test bow and the lower limb is almost twice as thick this is done in testing so the presure is transford to the test limb and it will take the pressure. we have been testing bow limbs this way for over 30 years.take a 60# limb and put a 38# on the other end and watch will happen with wood and glass in both .
