Estes Tube Cutting Guide

Wish I bought this earlier. Saves a lot of time covering up and finishing imperfect cuts. No more wasted tube from bad cuts. Would like to see a set for larger tubes and shims for alt sized tubes.

BT-5 (0.541" OD); BT-20 (0.736" OD); BT-50 (0.976" OD); BT-55 (1.325" OD); BT-60 (1.637" OD).BT-5 is the airframe and motor stuffer tube for 13mm mini rocket motors (1/4A, 1/2A and A10)BT-20 is the airframe and motor stuffer tube for standard 18mm rocket motors.BT-50 is the airframe and motor stuffer tube for D and E rocket motorsBT-55 and BT-60 are standard airframe body tubes.Larger airframe body tubes such as BT-70 (2.217"), BT-80 (2.600") and BT-101 (3.938") require cutting tubes the old fashioned way. The same for any non-standard body tube unless they're close enough that you can wrap a couple of layers of tape to allow a snug fit. Use a brand new, very sharp hobby knife.

Make cutting tube a snap. Like it a lot. Bry

So happy I got these. I make rockets often with my sister's kids and I dont know what I would do without these. They are great for cutting tubes, marking tube, fin placement, and more.

Very handy tool for cutting body tubes. We had some problems with the BT-5 and BT-20 guide fitting a little loose on those sized body tubes. Tried on several tubes and about 7 out of 10 had a loose fit with those two guides. Not a huge deal as a small piece of masking tape makes up the difference and still allows for a great cut.

Well made and easy to use. Allows you to get nice even cuts on body tubes. This product works much better than their fin alignment guide. It is hard to tell from the picture but each guide is actually a two piece unit and when you slide it on the tube you squeeze the two pieces together and the guide locks into place on the body tube without damaging it. Then just pry the two halves apart a little bit to get it to release and slide off.

Good tool for cutting standard size paper body tubes. Cutting guides slide easily over the tubes and tighten / un-tighten quickly. Make sure you have a sharp knife and make multiple passes to get a smooth cut. Great addition to your model rocketry tool set.

This is very handy for cutting tube without crushing them and it produces a straight cut.
