How to Make the Bottom of the Reels

Have you ever had to fund a reel before?

Surely if you’re not a novice fisherman, you’ve probably had to go through a spinning or casting reel and then you’ve certainly had to deal with the age-old dilemma of having to fund your reel!

Making the bottom in a correct way is one of those things that many people underestimate and on which everyone has his “magic recipe” to do it correctly. But a badly made bottom can give you several problems over time and even make you throw away entire reels of wire (maybe even expensive)!

Today, therefore, I would like to make you understand the importance of making the right bottom on your reels and I want to explain a simple mathematical formula to understand exactly how much bottom to load in the reel! But let’s go step by step.

Why Make The Bottom On The Reels?

Most reels have very large reels, this is because it must be able to accommodate wires of different sizes and especially in different sizes depending on the fishing we are going to do.

If, for example, we fish in a torrent, we will make relatively short throws and therefore just a few dozen metres of “good” wire will suffice. While if we fish from shore to shore or at sea, for example by doing some shore jigging, the meters of wire that we will need will be more and more!

Moreover, nowadays on the market there are modern fishing wires with exceptional performance but which have a high cost, and it would be foolish to think of loading the whole reel with a reel of these wires. This is because the more the reel of my reel is “discharged” the less performing will be my launch!

So to make the bottom is essential to be able to have the reel always loaded to the maximum and to be in fishing always with a good quality wire according to our preferences.

Do I Always Have To Bottom Up The Reel?

Not necessarily. There are cases where it is not necessary to bottom the reel!

If you think, for example, of the modern reels from Trout Area that have arrived on the Italian market in recent years, such as the Soare of Shimano, it is clear that their extremely low reel is designed not to accommodate any bottom. In fact, on the reels of these reels there are very few tens of meters of thin wire so you can load directly the mother line that we will then use in fishing!

Small Note Regarding The Braided Wire

With a braid you always have to go deep, even a few meters!

You’ll hear a thousand theories about how to avoid bottoming out on the reels when using a braid as your mother’s line, but you don’t mind. There’s nothing better than making a minimum of nylon bottom, even a few meters (for example on area reels), under the braid!

This is because the braid, unlike nylon, does not almost friction and can not “aggravate” on the walls of the coil.

On the market there are also reels with reels with rubber inserts or grooves to prevent the braid from sliding but I would advise against them. After all, if the high end reels do not use these pagliatives, there will be a reason, won’t there?

Someone might advise you to use a small piece of paper tape instead of just a loop on the reel to keep the braid still. But don’t listen to him!

The paper tape risks first of all to create an excessive thickness under the wire and above all it will tend to absorb the water carried by the braid. And you can imagine what happens to a piece of wet paper that has remained moist under a whole reel of wire.

How To Calculate The Amount Of Bottom To Put On The Reel

Now that I’ve explained to you the importance of making the bottom on our whirlpools, let’s see how to calculate the right amount of bottom.

One of the basic tricks I’ve always used in the past, when you still sold the spare reels together with the reels, was to load on the spare reel my mother line and then fill to the brim of the reel with the nylon used for the bottom. Once I filled the reel I just had to change the reel mounted on the reel with the virgin one and tip over all the wire unloading it from the reel just filled.

In this way I was 100% sure that I always had the right amount of bottom and I just had to recharge my mother line once I got to the junction with the bottom. But unfortunately nowadays most of the companies no longer sell the spare reels together with the reel, in particular on the reels of medium/high range. 

Let’s take for example the specifications of a very common reel like the Ultegra of Shimano. Let’s see for example that in the measure 1000 (ULT1000FB code in the table) there are 170 meters of 0.18mm and 140 meters of 0.20 and then again 90 meters of 0.25.

Let’s say that as a mother line I had to load 70 meters of 0.18 I should then go to cover the remaining 100 meters with my bottom.

Now, if the bottom I’m going to use will still be 0.18 but simply a less valuable thread there will be no particular difficulties and I will simply have to load 100 meters. But if the wire that I want to use is of a different diameter? maybe higher such as a 0.20 or a 0.25?
