This marking guide will make the building process of your rockets a lot smoother and you will notice an increase in the altitude of your rocket's flights. Is is just a good buy all around. I would highly recommend this purchase! (Posted on 2/11/13)
The tube marking guide makes it a whole lot easier to get your rockets just perfect. It is a great investment for anyone who sees themselves in the hobby for years down the road.I wish I had made this purchase sooner than I did! (Posted on 1/3/13)
I have used the marking and measuring guide now on two kits. Working with a group of boys, having the tool makes marking the tubes a breeze. I have used it yet on building scratch rockets, but I am looking forward to it. The tool is simple, but well thought out. While I haven't used the fin slot yet, I can't comment on it usefulness. I use a fin alignment tool for that part of assembly.
I decided to take the plunge and purchase some of the various guides stocked by Estes. This marking guide is great for measuring and marking on a range of tubes, and lets face it results in much straighter lines than the old doorframe method. Very happy with these and a steel at the price. Now I just need one to fit a 4" tube. (Posted on 4/12/12)
I bought this set of tools about 15 years ago, when I started building rockets again. I use it with amlost every build, especially when I build rockets from scratch. I use it to mark for cutting tubes, fin and launch lug placement, and to hold a tube when gluing fins. I even use the fin marking guides as stands for works in progress. I just wish it included BT-56 and BT-70 guides. Still, it's a must-have. (Posted on 9/22/11)
