Not only can you fix your rod when the tip becomes broken, but it may also be easier than you think. If you are fortunate and the damage is to the tip alone, you can merely replace the top with a brand-new one. However, if the damage is in fact to the rod blank at the tip a little more work will be required. To begin, you need to remove the old tip by cutting it as close to the end as you can. When doing so, though, try to avoid exposing the tip to too much heat as this could damage it.
From there, you will need a tip gauge to measure the size of the new tip top you will need. Once you have determined this and received the new tip top, you will need to glue it to the rod tip. As this can be a complicated process, it may be a good idea to look up an online tutorial video.
