Pretend this rope is in your pole. Cut your old rope, but don't let it come out of the pulley up top. Old rope on left, new rope on right. Line them up end to end.

I take a a piece of electrical tape and begin to make a splice by running it lengthwise along the ropes on the back side across the joint....

Then I do the same across the front side.....

Then squeeze it all together making it tight......

Then take the role of tape and begin about 4 inches above the joint to wrap the rope like a mummy in a spiral motion. Wrap it like you would wrap an ankle. Continue across the joint where the two ropes meet....

... then clear across the other side of the joint to a point about 4 or 5 inches beyond the joint.

You get the idea. Wrap it back the other way for good measure. How much do you wrap it? That is the million dollar question. Wrap it too much and it will be more difficult to pull the splice through the pulley wheel up above. Don't wrap it enough and it could separate up above when you try to pull it through the pulley.

So here you go. You're on your way pulling the new rope up through the pulley................

At this point, when the tape and then the splice meet the pulley wheel, you will begin to feel some resistance. The smooth gliding sensation of a normal rope sliding through a pulley wheel will begin to disappear........

At this point you are at the moment of truth. The fat thick spliced joint meets the pulley wheel. You'll feel it stop. The rubber meets the road. Everything you have trained for your entire life comes down to this one moment. Go nuts and yank the thing through with all your might and you risk using more force than you need. Yank too hard and you could cause the two ropes to separate leaving you with NO rope in the pole. Then you're a guy on the phone asking what the bucket truck guy charges you show up.

.......so DON'T do that! Just slow down, trust the nice firm splice you made, and continue to pull with only the least amount of  force you need to ease the splice through the pulley wheel. Feel the force, Luke. In all the years I have been re-roping flagpoles, I have never once lost a halyard.

Victory! Your new halyard is through your pulley.

Meanwhile, down on the ground, you have the splice back in your hand. Take it apart. Here I have cut it apart and in doing so, I have frayed the end of the new halyard we shipped you. When we ship you cut halyard, we cut it with a hot knife that melts the fibers on the end so they don't unravel.

New halyard to the left represents the new halyard coming down from the top of your pole. The old halyard to the right is still good for lots of uses around the house.

You don't have a hot knife so use any flame. CAREFUL. Blobs of hot molten polyester will drip like lava. They make quite a nasty smelling gas.

The end on top is halyard that has been melted at home with matches. The end below is halyard we melted with our hot knife. Ours looks prettier, but both methods yield the same benefit. They both stop the halyard's braid from coming apart.

So now you have the new halyard through the pulley up top and two loose ends in front of you down at the ground. TIE THE ENDS TOGETHER. THE HALYARD SHOULD BE TIED TO ITSELF FORMING ONE CONTINUOUS LOOP.

So now you are left with a knot in front of you.

I like to send the knot up to the top of the pole before I attach a flag. That way when I hoist the flag up, the knot will come down.

Hoist the knot up to the top of the pole before you attach a snap hook for the flag.

Now with the knot up top, I loop the first snap hook on at the bottom and attach the flag.

Just loop the snap hook on. How to rig a snaphook Make NO knots. Knots become like rocks after being tightened with use out in the weather.. Plus if you only loop the snap hook on, they are very easy to adjust up or down the halyard when you change flags some day.

Raise the flag a bit so you can add the second snap hook. Guess what? As you raise the flag, the knot comes down.

See what I mean? Hoist the flag all the way up. Now the ugly knot is down below where you can wrap it around the cleat which I do not show in these pictures.

One more thing. Take a look at what it looks like where the top snap hook meets the pulley wheel....

See how the snap hook grinds the halyard against the pulley wheel and/or the truck. This action creates a wear point on the halyard. For this reason.................

How to spot worn out halyard

........once I feel the top snap hook butt up against the pulley, I back it back dow an inch or so to reduce the wear on the halyard.
