Nope, I do mine with a razor, a lighter and a pair of needlenose for setting the loop. Make sure that you know how to knot the string before attempting. The results could be bad if it doesn't hold. I like to change out my loop quite often and purchased a roll of Brownell loop material through Lancaster archery for 24.99. This stuff is great to work with. The diameter is smaller than most and it seems very durable. It is 100% nylon so it balls up on the end when hit with the lighter. Again, make sure that you know what you are doing first. If you are tired of rubber tubing on your peep and having trouble getting the string trained. You can serve the loop to the string by making a loop in the serving material and tie it to the base of the loop. Take and separate the ends and wrap them around the bow string , using half hitches as you would in making a tie on nock. This will give you control of the string thus aligning your peep. Worked great for me. Good luck.
