Anybody have any tips for testing the breaking strength of homemade flouro and sevenstrand leaders? In particular, I'm pretty nervous about the knots I'm tying in the sevenstrand and would like to run some tests to see if they are consistently strong. Treats, I expect you've some experience here; you seem to think a little like an engineer raised in Missouri (the "Show Me!" state). Thanks.

Ranger,first thing you will need is a peak reading scale. I don't know how much one costs but you can get one from W.W. Grainger or any of a bunch of industrial supply comp. out there. Then something to pull the leader smoothly until it breaks. Then read the peak poundage on the scale. Anything will work to pull on the leader when hooked to the scale. An old boat winch comes to mind. Let me know if you go through with this. I will be interested in your findings. Could check out line break strength, knot strength etc.

Get a heavy metal coat hanger, and fashion a loop at one end. Wrap it around a beam in your garage, and twist it off.

Attach your leader to the hanger, so that it hangs down.

Take a piece of stainless steel wire about 16 to 18 inches long, and form loops at each end, so these loops will attach to the snap of your leader.

Start adding weight (using old weights from a weight set). When too much weight is hanging on that leader, something is going to let go. Note the weight on the leader at the time it broke. You'll likely need to test 3-4 leaders to ensure consistency.

Worked for me. You may need up to 150 pounds in assorted weights... the plastic covered ones are best. You can usually pick up a variety at yard sales for a couple of bucks.

Happy testing!

Ranger;
If you can get a Chatillion (?sp) 100 pound spring
scale ,you can secure your leader to a beam,heavy bench,
tow hitch and then pull while you watch needle.You could
also place the scale between your leader and large
bucket like Steve mentioned . Add bricks until leader
breaks.Note weight.Figure an average from ten tests,
after you drop off lowest and highest .Actual average
is from eight tests .
luck

You can also get a 300# deer scale,I have seen them for around 60.00$. That would be more then enough! Handy

So when ya find out how much it will hold...how does one know or compare that to the pressure a Musky will inflict on it..?

Secondly...do not put one of the leader on a hook screwed into your bench (even if it is 8' long and full of tools) and put a screwdriver blade through the other loop and pull like the dickens to see if it will let go..[8)]

Oh yea...Curly did this once..the leader held just fine..took me three hours to clean up the mess of a tipped over workbench though..[:bigsmile:]

Also do not put one end of the leader on a hook screwed to the garage rafters and hang from the other end.... That leader didn't hold...and Curly come a tumblin down.[:bigsmile:]

I like the scale and winch ideas or the bench weight idea...

But I still wanna know..how many ft. pounds is adequate.

Great ideas, thanks. A local bait shop has an excellent certified bear/deer scale, I bet he'll let me use it for testing purposes. Now to find a weights set, or just use water in a big container.(8lbs to the gallon, right?) I'll let you know how it turns out.
