      "Oh man, these things are so trick. I used them on all my motors at the Snowbirds. The brush looks like it has been run for a couple of runs and it is so smooth. The motor is extremely efficient and the power is perfect right from the get go. I noticed that the wear on my 9x1 in touring car was less, I usually have to cut the motor every run for best performance but the fussy brush whatchamacallit was keeping the comm more clean and I could run easily two times without discoloration. This is a great tool and should be in everyone's tool box, I just don't see how the heck you came up with the design, it is so trick."

      "Hello I would just like to say that I received the fussy brush today and we put it to the test. We have all of our motors saved on the dyno from after a fresh rebuild. We spun up a few motors that had a run or two on them and got some new numbers, then we used the fussy brush on them and spun them up again and our smallest gain over a fresh rebuild was 1.2 watts and our biggest was 3.4. This is by far the most remarkable tool that I have. The person I was dynoing these motors with went and ordered one right away (you'll see there is another order from central Illinois) Thanks very much for the timely shipping and for a great product."
      "I have been using the FussyBrush's religiously on all my motors. I am seeing less comm wear, longer brush life and more consistent performance."

    If your tired of using up your time and commutators seating brushes then this is your solution. Our Brush Shapers are both fast and accurate. This tool will shape full face brushes while inside the motor can. This means it will accommodate for all of your hood alignments.

   If you've ever tried re-shaping laydown to standup or standup to laydown then you know it is really impractical to do on the motor commutator. Problem solved. Shapes serrated, regular, slotted, timed, drilled or any other configuration to the internal specifications of your motor.

    Two sizes available. .295" (7.5mm) diameter for standard size comms and .345" (8.79mm) diameter for large size comms. Made of Stainless Steel - This is the original FussyBrush shaper. This is a fixed bit on the shaper and is not interchangeable

      "Got a set of shapers from you. I don't know how to start. Well, I was really excited when I received them and saw how they worked. After reading the instructions, it seemed straight forward to use them. Last weekend I ran mod (Reedy T1s). First run I had new brushes and comm cut. Ran the first heat of qualifying, it feels the same as I normally find on my car. But in the second heat, cut the comm again but this time I prepared the brushes (729) with the shaper. This time, don't know what happened...I had so much more power. Unbelievable. I did it again for the 3rd heat, I got faster. My lap times are very consistent and it gets faster and faster. This tool of yours is doing a great job. No more motor break-in on stands. I can get my motors ready for action in less time than I used to. Before, sometimes I would even skip the motor break-in as time was tight. Now I have all the time I need and know that my brushes and motor will perform for me. Thanks for the great product."

      "Not only is your customer support outstanding, but the product is awesome. It saves us tons of time at the track and is just plain easier to use, not to mention the tools drop right in my pit box."
Brush Hood Alignment - As your shaping your brushes the alignment of your brush hoods becomes really obvious. You can see this when breaking in brushes the old way with the comm, it just takes longer.
      "I am not a motor expert, but I do understand the basics. It's really nice when all you have to do is reassemble a motor and go, with no break-in nausea. Additionally, the shaper is saving me money, in that I am re-using the same brushes more times. I cut my stock motors every three runs, and I have just been shaping the brushes lightly at rebuilds (other than when I put in new brushes which get the full treatment). Also, the shaper is great for aligning brush hoods - for alignment purposes alone, the shaper is worth the money. The bottom line is that my motors have gotten noticeably faster, while I am putting in less effort and time working on them. Thanks for the great product!"
    Here you can see how it installs. Really simple. The spring is there for stability without having to shim to your motor. Turn by hand a few times and it's done. I have a piece of shrink wrap installed over the pinion but it's not needed. You don't need to install the springs. It's faster to just apply a little pressure to the brush with your endbell philips screwdriver.
    Reedy KR 12 x 1 Brushes seated with Fussy Brush. Notice the brush shavings and how the brush face is dull, not glazed. That dull finish is softer and dissipates faster, keeping a fresh brush face longer as you race.
    Commutator wear on a brand new Reedy KR. I don't know about you, but I get a little upset when I have to cut a new commutator to repair the damage from breaking in the brushes. Yes, I did use low voltage, and yes, I did drop the timing back. You get commutator damage breaking in brushes even if you use a drive motor. Another problem solved. Let's say you go through 8 sets of bushes for the life of the commutator. Even though you only have to skim the comm to get rid of this, that's 8 less times you have to skim it.

      "I use the 285 unit at least two or three times a week. Honestly, I don't know how I ever got along without it. You folks should be quite proud of your products."
      "DeWayne, As you know from my original letter to you I was impressed as hell with the fussy brush. Well I have to admit
and I don't know how you will take this, but thru my many times of using the fussy brush at the track I have had terrible
success. There was too many times that after the heat races and placing in the A main that I would go thru the motor and pull out my best battery and get ready for the race, and then Pow. too much power, I don't know how many times I did that, you
would guess that a guy would learn after a bit but when you have the tools, you need to use them. Well the bright side
is it will make a better driver out of me. So in ending you should feel guilty because I'm sure that I am not the only one
that has had to compensate because you just had to make a quality product, and then on top of that we have to deal
with unsurpassed customer service......How dare you!........Dewayne, if no one else says this to you then shame on
them,,,,,,,,, THANK YOU!!!!!!! Please do keep me in mind for future products.
