Stabilising forends with . . . a carbon fiber arrow shaft?
@ 01:54 pm (GMT) |
J. Ryan NielsonA student, and former military gunsmith, suggested stabilizing the fore end by routing out a channel for a length or two of carbon fiber arrow, after keying in places for the epoxy to grab. His thought was to stiffen/stabilize the fore end without quite as much weight. Any thoughts about how reasonable this is?Thanks. |

Andrew MurrayRe: Stabilising forends with . . . a carbon fiber arrow shaft?It sounds a little more involved than it is worth. I used the stock stabilising compound and it was quite easy to use and stiffened it right up on my Howa/Hogue. The total weight is about 200g if you use to whole compound. I didn't need all of it but even if I did, It's less than 7 ounces that it would add.This dint need to be complicated to be effective. |

Bryan WebsterRe: Stabilising forends with . . . a carbon fiber arrow shaft?I agree with Andrew, however he did not note that the fore-stock stbiliser compound is sold on this site along with the bedding compound, Nathan Fosters own child, and I would go that route if your present stock is a worthwile one. |

J.

It appears quite convenient. Interesting. Though adding seven ounces to a scope, heavier contour barrel, or other accoutrement usually raises some eyebrows. |

Grant LovelockRe: Stabilising forends with . . . a carbon fiber arrow shaft?Yup I have used carbon fiber arrow shafts to stiffen fore-ends.... it works well when used in conjunction with Nathans stock filler.... the only part I have trouble with stiffening is at the Recoil lug junction.... if you have movement through this section it is very tricky ti fix as there is not much room to work with to get any bracing through under there. |

Chris BayleyRe: Stabilising forends with . . . a carbon fiber arrow shaft?I used to use carbon arrow shafts to make model gliders and I find them WAY more flexible than my Tikka forends... like 50-100 x more!So I have some trouble imagining an arrow shaft adding much stiffness to a forend unless it was made of rubber..... |

My son and I discovered this as well so we eventually gave up and tossed the stock and put the rifle into a Bell & Carlson stock then skim bedded it and it really shoots well now. Problem solved. I know there are better stocks out there but we have an importer close by who got it in for us with no fuss. |

Nathan FosterRe: Stabilising forends with . . . a carbon fiber arrow shaft?Grant has to deal with some pretty ridiculous tactical stock designs, all looks, no function. True-Flite use our compound and methods.Normally, the lug area is rendered a non issue by ensuring that we actually bed the rifle after stabilizing and bed the start of the barrel channel. This is doubly useful on extra long and heavy barreled rigs. If these are free floated, they can place a lot of strain on the action resulting in harmonic accuracy issues. But if the rifle has a more open forend - as in the customer brings in a tactical style stock which does not allow the rifle to be bedded out to the knox, we may sometimes be unable to rectify the weak point at the lug (forend side of the lug) intersection. This is also discussed in the online instructions for these products and videos (Video learning). This is what Grant is warning against- that the two products work in conjunction with each other on a plastic stock. If you bed the action and stabilize the stock but leave weak parent material un-strengthened between the two areas, all bets are off- more so for those who like to hang off the end of a bipod. You can use the arrow shafts to reduce some weight but do not expect increased strength. Strength of our stabilizer once cured is not an issue. If you see any remaining flex, look to the problems Grant warned against. In other words, the area we perceive as flexing may not actually be indicative of the actual flex point. On the M700 SPS varmint rifle (a very useful budget starter rifle), the stabilizer will make the rifle slightly heavier (around 100 to 120 grams). Roughed up arrow shafts can be put to use as a lightweight filler if need be. But otherwise, there is no need for this. For a true weight change, the barrel can be docked 4 to 6", making little to no difference to velocity in either the .223 or .308 chamberings. In some cases, one only needs to stabilize a third of the forend which can also save weight. The fact that most new players miss, is that I did not design the stabilizer purely to fill entire forends. I designed it to raise the level of the inner forend at the start of the barrel channel, simply so that I could bed the start of the barrel channel without having to pour 200 grams of metal filled compound into the front area of the action. By filling the voids at the front of the action / start of the barrel with a light weight filler, then adopting propper bedding, this alone can remove a great deal of flex. But to be sure, I generally recommend stabilizing the entire forend. this also helps prevent any weaknesses at the front sling stud. Such things become apparent with time and experience. |

Paul LevermanRe: Stabilising forends with . . . a carbon fiber arrow shaft?I wasn't really sure if I should tell this or not, but anyone who knows me thinks I'm kind of weird anyway. I took a perfectly well bedded Boyds stock that fit my Norma perfectly, and carved out two narrow grooves and re-bedded the action with a piece of aluminum cleaning rod in each groove. Why? Because I thought I saw the forend flex when I laid it across the bags. Did it work? Not sure, I don't see the flex anymore, but then maybe I never did. |

Kenneth KephartRe: Stabilising forends with . . . a carbon fiber arrow shaft?Yes, i've done this to my Stevens 200 in 7mm-08AI.I had a couple of bad arrows and some epoxy from when i worked on aircraft laying around. Really helped. |
