hey guys, I have a quick question---------for 5/32 amsteel blue, how long is a fid? the only chart I came up with shows a short fid, a long fid, and a full fid. which one do I use? Also, does it hurt anything if the fid is a little longer than what it call for? Thanks!
FYI: If you want to know what type a certain bear is, sneak up behind it and kick it. Then,
run like crazy and climb up a tree. If the bear climbs the tree and eats you, it's a black
bear. If the bear just pushes the tree over and eats you, it's a grizzly bear : )
Do not walk behind me, for I may not lead. Do not walk ahead of me, for I may not follow. Do not walk beside me, either, just leave me alone.

stevebo - A fid is 21 (or 22) times the diameter of a rope, so in your case it's about 3.3". Fids often have a line on them dividing it into two sections. The long fid section is 2/3 length and the short fid is 1/3. The fid is the measuring tool since instructions describe how long buries and tapers should be in fid lengths, not inches or mm. Hope that helps.

There are also wire fids and tubular fids. MOST folks use tubular fids with hollow braid while wire fids are used more with double braids.
If you find yourself using wire fids, 1 fid length would be equal to 2 wire fids.
Just to make it more confusing.
Thanks guys--------i think Ive got it now!

The big reason wire fids are shorter is that they are sold for the larger diameter ropes. If they made tubular fids for the big ropes they'd be too large to handle easily.
For splicing these small ropes I use the doubled over thin wire, and a measuring tape to get the fid lengths. I'll calculate the needed length and round it up to the next inch for some safety margin.
a fid is exactly 7 times the circumference of the rope.
The circumference of the rope is pi times the diameter.
Thus:
1 fid length is: 7 * C = 7 * 3.141592654 * D = 21.99114858 * D
C == rope circumference
D == rope diameter.
For D == 5/32 = 0.15625
Fid length = 3.436116965" or approximately 3.44"
22 * 5/32" == 3.44"
Note some people will tell you 21 * D with the mistaken assumption that pi is equal to 3. Probably good enough for government work, but I wouldn't use 21 otherwise. 22 is much better.
