Have you been putting it in the bow press? The bow press position is vital for bowtechs.

The set of limbs that came on my 06 old glory had about a dozen cracks that ran across the limb... thats from poor manufacture or materials, I agree with erika... bowtechs limbs are really pushed to their limits and you need to be very careful with them in bowpresses.

I've had five Bowtechs, and not one limb failure.
Of course I'm not saying it doesn't happen. I have seen a number of Bowtech limbs crack on other's bows. You do need to be very careful when pressing them. I'm not saying incorrect pressing technque is the only cause of failure either, but it's certainly the major cause.

My goodness DWD...the calibre of your expert contribution astounds me.
My "cheap ground" limbs are shooting extremely well, and accurately thanks :thumb:

None of my limbs have splintered... well except for the bow that Marcus borrowed. Clearly he's just a bad husband. :D

Like the AAPT ad says 'tell it like it is'........now your gonna tell me that ground glass limbs are not the cheapest form of compound limb available? Makes good economical sense to replace the one in a dozen set that splinters, didnt cost them that much to begin with ;) Looks like the Bowtech fanboys (and girls) have migrated from AT :)
Marcus

Don't forget they are the same limbs as used by Mathews, Pearson and a whole pile of other companies. ;)

Nope...Like I said - I've seen a number of Bowtech Limbs crack. I'm not going to say they don't, or haven't. What is factual, is as I mentioned because of the angle of the limbs, a vast number of the failures are due to incorrect pressing technique.
What we don't need is cheap, useless comments like yours above. That's the sort of crap that I'd expect to read at AT. I think you've been hangin' there too much.

How is it a raw truth DWD?
:silly:
What do I care?
My Bowtechs work great. I said it three or four years ago when I got my first one, and I'm still sayin' it.
Yet to experience a failure of any kind.
:rolleyes:
Sure...I've heard of Bowtech limbs failing. Big deal. I've also seen great warranty support too.

Sorry to hear that.
How many grains of arrow weight per pound of draw weight are you using.
A friend of mine was shooting an 05 Allegiance with 5.3 grains (crazy 3Der:silly: ) arrow weight per Lb, he was getting blinding speeds but having limb failures (3 in 6 months).
He mover to a heavier arrow and the limb problems are gone (none in 12 months).
Maybe just be a coincidence?

Only prob with mine was when I inadvertantly clipped the limb on a rock causing a splinter. Purely pilot error. Since then limbs replaced, under warranty although clearly not a warranty related issue, (thanks Bowtech) and no more probs. Know of others who have had no probs and some who have.... but then again that goes with any bow.
PS if the splintering is a problem for you..use Loctite 401..on and around the area of the splintering. It dries clear and on mine the mend was virtually invisible.

I have had a few limbs go on my early bowtechs, it had nothing to do with the pressing of the bows, I put it down to the aggressiveness of these bows, most bows seem to handle Gorden glass limbs o.k.
I didn't think Mathews used Gorden glass limbs, I have had a few splinters on Mathews limbs as well. I've had the best run out of Hoyts.

Hoyt limbs are excellent... i have never heard of one set splintering or failing (compound that is... ive seen a fair few G3's explode :lol:)

sorry seen Hoyt limbs do it too.
And Mathews
Dr Who?
27-02-2007, 07:19 PM
Have to agree with Marcus - we have seen both Mathews and hoyt limbs go although very few and far between.
Now several years ago we were importing Champion - we stopped after the second batch - worst limbs I have ever seen - great warranty and service - but terrible limbs.
Don't forget they are the same limbs as used by Mathews, Pearson and a whole pile of other companies. ;)
I was of the understanding that Mathews limbs are laminated carbon/glass . No ?
Hard to see under the black laquer.
The Mathews manual does recommend winding the bow down before using a bowpress. Well worth heeding for any compound I'd suggest.

The parallel limb attachment we have on our Deiter's press works very nicely.
You can relieve pre tension on the limbs by backing them out a couple of turns before pressing them, and then ensure that the press rollers are not seated too close to the limb pockets.
I've pressed dozens of Bowtechs in regular presses....just ensure that the press rollers are as close to the axles as practical.
As mentioned, the Dieter parallel limb attachment makes it easier. Seat the bow in the press as described, then apply some pressure before winding in the parallel attachment to complete the pressing action.
Easy.
:thumb:
You'd be surprised (and scared!) to see the things I've seen people do in front of bow presses. I've seen damage you wouldn't have thought possible through incorrect pressing technique.
:D

I remember this very subject on a thread some time back & it was clearly stated that Mathews had a carbon/glass laminate.
Maybe some Mathews overenthusiasm ?
Not that a straight glass limb worries me at all.
Hoyt probably make the best quality limbs anyway.

i just dont understand how people can keep going over and over the same arguement. as marcus and others have said sure bowtech limbs fail, not always due to the product, some user error to. but what did impress me when i had my bowtech was how fast and easy it was to get new limbs.
my biggest hassel was getting to the dealer to put them on.

I have had limb failures on PSE and Mathews and would not be surprised if it did occur on Bowtech. I don't know of any manufacturer claims that their limbs are unbreakable.
Apart from the initial angst and temporary inconvenience, the main consideration for me is how promptly and unequivocally the retailer and manufacturer leap to replace the limbs under warranty.
It can happen, and you just want to get going again.
where can I get info on the attachment on the Dieter bow press for Parallel limbs.

No they are made the same way as Bowtech make theirs. John Dudley went over it.
Hoyt's may or may not be better. But bare in mind that the way the limbs work are drastically different.

I'm no tech-head Marcus, so are you suggesting that more parallel limb set increases the stress on the limb ?
Due to the shorter limbs having to work harder ?
The early PSE moulded glass limbs were long in comparason, but certainly stress cracking was common.
I wonder how the 2x new Bowtechs will go then ? Different set-up again.

I have seen breakages with just about every make of equipment I can think of.
I think it fits in with "if you do not fall over occassionally, ski faster".
That is: most archers seem to demand ever-increasing performance from their bows. This means that the manufacturers need to push the materials and designs harder and harder. Generally, as an engineer you try to keep within the bounds of not breaking things (not so good when your bridge or building has a significant failure). However, aside from bridges, buildings, rockets, and the like, with things like bows and racing cars the material limits do get pushed pretty hard.
Hence, it is normal practice to expect failures, so long as the numbers are not too great and archers don't get damaged.
However, I would definitely expect a competent engineer to know the usual traps of things like sharp internal corners, etc, and to not fall into them. It is there that the non-professionally qualified designers (the non-professional engineers) do get into trouble more often than you would like to see.

I dont shoot a Bowtech any more but I dont believe that the high number of Bowtech limb failures are mainly due to the way they are pressed. At our club we had quite a few Bowtech limbs fail yet none of the Mathews parrallel limb bows failed and we used the same press and operator. I had a Bowtech Constitution that cracked 4 sets of limbs yet the Pro 40 Dually, Ross and Legacy I have had no problems with, I use my own Dieter press and only I work on my bows, I was very careful with the Connie yet it kept cracking limbs.

Or you could just make one like mine yourself for $160au

Hi Kite, the rollers under the cams, are they free floating or locked in somehow? My first home made prees was a sucess and failure. It works but not well. Looking for a better one.

What do you think about the Bowmaster Portable Bow Press? With the optional brackets it places pressure almost directly over the axles, so *should* put no more stress on the limbs than drawing the bow.

Yep , I've seen a lot of Hoyts with split limbs too :cool: :silly:

Hi Gang,
I have been shooting a Browning Micro midas 3 for the past 7 months, the bottom limb splintered, while both libs showed signs of fatigue, Bensons Archery did a great job with the warranty but were held up by importers of the replacement limbs, goes to show it can happen to any bow.
thanks

I have used the Bowmaster for 3 years now- no problems. Have changed strings/cables,but it is used more for adjusting timing on mine & other peoples bows. Only takes me about 3 minutes to adjust the timing on Hoyts.

I would imagine ideal for parallel limb bows.
I'd better not attack my Vectrix XL with my current bowpress.
The Bowmaster sounds like the deal.
Anyone ?
I keep one in my kit for adjustments in the field but there is no substitute for a full sized press.
Ozzy, the press in the plans in the tunning sticky works very well on all parallel limb bows, (I have not tried a guardian or commander yet though).
