1 – Using a clean white paper towel, apply denatured alcohol or equivalent cleaner to area where vanes are to be applied. Continue to wipe until no carbon residue is visible on white towel.
2 – Wipe base of chosen vanes with same solution, some manufactures use certain agents to release vanes from the molds which can cause vanes not to stick
3 – Avoid touching all surfaces to be glue and keep in a clean work space ready for the gluing process
1 – Screw in an old field point and begin to carefully heat the tip whilst slowly rotating shaft
2 - After 15 seconds (times will vary depending on brand of glue) lightly grab outsert with a pair of pliers and gentle pull and twist shaft and outsert at the same time, if no movement continue to heat for another 15 seconds until both components are separated.
3 – Always flex and inspect shaft after completing this process and if any visual signs of damage shafts must be disposed of and not fired
1 – Whilst straightness of any arrow shaft is important the difference between say .006” to a .001” wont be overly visible to the naked eye. What is important however is having a consistent spine tolerance which is the “arrow flex” the same amount every time when it leaves the bow
1 – You will need to find and mark your balance point of your shaft by balancing your arrow on a narrow and or edged surface some will even just use a finger (mark)
2 – Now find the centre of your shaft by dividing the total length by 2 again marking the shaft of this point.
3 – Measure the distance between these 2 points and divide that number by the total length of the arrow then multiply by 100 will give you your FOC percentage
Eg – 3.5” divided by 28.5” = 0.122 x 100 = 12.28% FOC
Honest answer would be, Every setup if different and what works for you might not work for someone else, Different cable systems, rests etc might dictate the height allowance or vane configuration to avoid contact. Keeping in mind that longer and heavier vanes will subtract from your arrows FOC and will also reduce speed. Broadhead design will also be a contributing factor to arrow flight so it will mostly come down to trialling a few different ideas and combinations
This will require 2 people and a marking pen.
Using a full length arrow draw your bow using your preferred release aid coming to your anchor point and once you are comfortable get the second person to mark your shaft inline with the front of the riser. Let bow down gentle and measure from the back of the nock to the line marked on your shaft. Using a certified high speed arrow saw cut the position and install the appropriate hardware and point/head and draw bow again to double check before cutting all your shafts. Keep in mind that all Naptyme Outserts will cover your shaft by 15mm
NOTE – Its always a good idea to keep the back of your broadhead in front of your fingers to avoid any nasty mishaps
