Do you have pictures of how you have the limbs taped and I'm assuming that I would need a crossbow press to do this.Sorry to here about the crossbow.
Limb slivering is a common problem with the Carbon Express 390 Pile Driver, the rebranded
Rocky Mountain 405 and 415 models. These models are no longer manufactured. There is a
new version of the Rocky Mountain 415 shown on Feradyne website as "Wish List" that has
been there for many months. It is still not available.
The older model Rocky Mountain 405 and 415 can be purchased from some sellers or companies
that may still have them in stock.
Another crossbow that has limb slivering problems is the Bruin Ambush 370. I have all these cross
bows I mention being many parts will inter change. The crossbows are manufactured in Taiwan.
Other than the limbs slivering, they are very high quality.
Getting back to your crossbow, it can be modified to re enforce the limbs even though yours has a
slight damage. Remove the riser and take off the string and cables, tagging them for how they are
now twisted. Starting near the cam, wrap the limbs as tight as possible with high quality electrical tape,
going to the end of the limb where it fits into the limb pocket. Once assembled back the cams off by
either removing equal 1/2 or full twists from the single loop end of the cable where it goes onto the lobe
of the cam. Another way is removing 1/2 or full twists from the bow string. Do one or the other but not both.
Some recommend shooting a heavier arrow-point combination. All this does is slow the arrow down. Not
backing the cams down a bit, the crossbow limbs are under full load whether in the uncocked or cocked position.
Several years ago when my Carbon Express 390 Pile Driver limbs started to sliver, I contacted Feradynne.
I was quoted $150.00 for limbs and $100.00 shipping. This was to Canada and then add up to 35% currency
exchange to this plus import fees. It was cheaper to purchase a complete crossbow on sale where I had all
the other parts.
If you do decide to purchase a new crossbow of any of the ones I mention, I recommend the limb taping and
backing the cams off a bit. These crossbow limbs can not take constant cocking and shooting. I had one fail at 330
shots, a 2nd. coating chipped at 1300, then slivered at 1400. Taping those limbs on the second crossbow, I was able to
go to 2650 shots.
As a test I have salvaged the stronger limbs from 2 of these crossbows (even though the limbs were weaker than new)
and have shot an additional 500 shots with the limbs taped and cams backed down a bit.
After several tests with an additional top serving layer of BCY .030 in the arrow-latch area, I removed the base serving
as the bow string was not built under enough tension when the serving was applied. The serving was not installed under
enough tension either. After this modification, the original bowstring had slightly over 11,000 shots and the top layer of
BCY .030 serving has slightly over 5,000 shots. Today, I am still shooting the original bow string with an estimate of well
over 15,000 plus shots. Other than the serving in the arrow-latch area, Taiwan builds very high quality bowstring and cables.
The crossbows I have mentioned will all accept the crank cocking device that plugs into the cross in the butt end of the stock.
This is a very high quality device. I have modified some of my Barnett crossbows to use this same device due to the fact it is
better quality and much safer to use than the one designed for the Barnett Ghost series and Drop Tine STR. For the Barnett's
I had to switch from the hooks to the sled due to the way Barnett's stock is shaped near the fully cocked area. With care, one
can even decock the crossbow with this device.
I am still shooting the original stock from the Carbon Express 390 Pile Driver with these other crossbow risers, limbs and
doing various testing, 25,000 or more shots with absolutely no trigger problems.
Wishing you all the best with what ever you decide.
Yes, the crossbow has to be put in a press in order to remove the string and cables. Once these are removed,Do you have pictures of how you have the limbs taped and I'm assuming that I would need a crossbow press to do this.
Thanks for the update.I just had the limb replaced by by carbon express they will repair it as long as you still under warranty.
This is the second time for me in 2 years
The price on that crossbow may sound cheap for the reason it is manufactured in Taiwan.I only called the company they directed me to there web sight where I have to input the info on the crossbow to see if will be in warranty, unless it's no longer in stock. Think after I pay for shipping and what has to be done to fix it, I may just use this for lesson learned off buying cheap crossbows, and buy something else what's a good crossbow out there ?
PM Hunterthompson or Tomontherun.
