Our limbs and there construction

[BorderBows]

I thought id get this one out to help clairify some of your questions...

This is off the top of my head chronology of what limbs you have and what they were made of, and when they were made.. Remember it is off the top of my head so it could get a bit patchy
Started 11 or more years ago.

15 or more years ago till 11 years ago.
Vision Carbon : Glass powered, Wood core, with a carbon support. (it held a world record)

1998 for a year or so.
XP10 and the XP10 Evolution: Same construction as the Vision carbon but the conceptual use of the carbon changed. This was the limb that had the first Stabilisation built in. The Evolution was our first Syntetic core

1999 or so,, for about 18months to 2 years.
ML2 Took on the Black Douglas limb profile and had our first synthetic core (Hyperflex MK1) This limb had higher cord ratios, which made it smoother and faster. The increase stability was used due to the increase the cord ratio. It still had a glass power structure.
Border SM Carbon. These were an ML2 Limb but with a wood core


2001 years ago, for 2 years
Talisman TX40 Gold, Silver, Bronze.
This was a TX40 looky likey. It was the TX38 Laminate. It was the start of the Multi Core options. They had Wood core (maple) Superflex (pink coloured core, low cost) and the Hyperflex core. The Hyperflex (mk2) core was a fraction lighter than that used in the ML2, the Superflex was a half way house between the maple and the hyperflex core.
The TX38 Laminate was considerebly lighter than the Glass powered limb, and the Stability laminates were closer to the surface, providing more stability for the same material.

2004 years ago till 18 months ago,
The Talisman limbs changed to the TXG,TXS,TXB when we changed to the TX40 laminate which was again, off the Black Douglas Hex4 Limb. The core options were the same as the Talisman Tx40, so were the recurve shapes. The limbs also recived a couple of re-enforcements in the right places to help the minimum arrow weight stats, which was mainly aimed at the folks shooting at the extream ends of the product design.

2007 months ago. for 2-3 months.
We dropped the silvers, and changed the product line up.
two cores options, with three limb profiles.
The TX40 was at the heart of the design. The superflex core was dropped, and the core options were Wood or Hyperflex. Bamboo is a core, as an optional extra on the wood cores.
The recurve profile options were the TX recurve, HexIV and HexV.
The TX was the same recurve shape as the ML2 onwards, the HexIV is the same as the Black Douglas Hex4 and Provides more stored energy. Giving more speed, and smoother draw.
The HexV, is the same idea but with more emphasis on the smoothness and speed, but also on a quieter shoot. This has come about due to the number of ILF archers looking at hunting with these limbs.

For the last 2-3 months
Production has been on the CXC laminate with the TX, HexIV & V lineup. The CXC laminate has a reduced mass, and approx double the torsional stiffness of the TX40 laminate. We are looking at new logos. Orders on back order are being "upgraded" as we dont have a product launch as such, we phase most changes in with time. The TX limbs are about to change to CX. Making them CXG, and CXB.

other limbs.
These are limbs that were not eventfull in them selves, but were full spec limbs in their time that would have suited a different budget or were made for another company (ILF only)

Carbons: These are for all purposes the SM limbs with a few changes.
Carbon Premiers: These were the Border Carbons but made for Wales Archery
Merlin Elites: ML2 limbs for Merlin Archery. 2000-2001 about
Merlin Classics: Same as Border Carbons
TX: These were TX40 limbs just before we managed to get the logos sorted.
Carbofast: These were rebadged were similar to the SM Carbons again

This is approx. It would take up a good few hours looking up exact specs, and details, which i can do on a spec by spec basis and I'll update as i go, but here goes for starters. Time does odd things to memory

Sid,

That is a very informative post! Thanks for initiating the thread. It answered some questions I've had.

We have had a good idea of a development plan.
The concept has been Materials one year, Shape the next.

The Practicallity of the whole thing is you do get some good ideas, and when you get a good idea, its not worth holding it back sometimes. Hence the Black douglas Hex4 Limb.

The Hex1,2,3 didnt really come about as they were prototypes. There are a few hex3 about but really not many.

The hex3's had full tapered glass fiber as a means of lighter materials, but the carbon in the TX40 gave us what we wanted.

The TX40 is an S2 Glass Limb, which is the same layup concept as the Samick limbs. The Zentron material from what we can gather is almost a S2 Glass. Its a great material. With the strength of meduim Carbon, but weights the same as glass. It did give the Hex4 the kick it needed. The Development also worked its way into our Black series Flat Bows.
We keep this stuff to our selves as patents are not a price we can afford to pay or defend.
There was NO bow company out there using these materials when we picked up the can in 2001 that we are aware of.
S2 Glass was not a common product back then.

The Idea of using materials to gain stored energy by way of stabilising shape is something that other companies far larger than us have not explored. The Idea that we have been hiding untill now, our target Limb prototypes in the Black Douglas range means that the Black Douglas is a trend setting bow, which the big Target companies have not seen. The recurve shape in most modern Target Limbs is a Border Black Douglas Feild Limb, Stabilised by using XP10 Carbon. Which was launched in the Target Limbs in 1998.

The ML2 was our First major leap into shape and our ability to control it.
