    Our small club has a GMV Superstar ATM trap that has developed a tendency to throw 3 or 4 high targets every once in awhile. Nothing seems loose or out of adjustment. I'm drawing on your the vast pool of knowledge and experience for some sugestions to correct this problem. Serious responces will be appreciated. Thanks in advance.....Jerry P. Felice

    You don't say exactly which trap you have (singles, doubles, wobble??).

    There are two areas to look at...

    First are the brushes that press down on the targets when sitting on the table - they wear over time and need to be adjusted every now and then.

    Second possibility is the singles/double arm than is lowered when trowing doubles - it can drift downward over time and if it gets too low targets can slide on top of it which will affect how birds are thrown.

    The owners manual explains how to adjust the brushes.

    The singles/doubles arm needs to be pressed up from the bottom to see if it is loose (if it is, it will move up when you do this) - just needs to be re-tightened once on the regular place. A single bolt holds it in place.

    Replace the old style brushes with the newer ones. No adjustments after they are installed.

    Ed, I'm not familiar with the "new style" brush. Where have you obtained it?

    Jerry Felice, We've had that problem with one machine, we call it a "flipper", might happen 3 or 4 times in 100 or so, usually not in succession which didn't make sense. It seems to be in the brush adjustment and making sure the target doesn't get pushed too far off the arm, per the book. Also, you can't rule out an imperfection in the target itself. HSLDS is correct on checking the arm for the proper height. Good luck, Bob

    If for some reason the target gets "pinched" up on the arm rubber, you will get a flipper. Target chips, dust, or deposits on the launch plate will cause this. You might roll the edge of the rubber with sandpaper ever so slightly to relieve the pressure.

    The above suggestion are all valid.

    I work on the two Super Star trap machines that we have. (Manheim Sportsmen Association)



    (1) I would suggest that you remove the magazine and give the machine a GOOD cleaning removing all the broken target debris.


    (2) Replace the rubber o-rings on the: two target retainer wheels and the four outer retainer wheels. Clean the plastic wheels and apply a light oil on the shafts.


    Reassemble and run the machine WITHOUT any targets making sure the elevators are moving up and down.


    If this does not resolve your problems you may need professional help. Here in my area (Southeastern Pa.) we use Shyda's Services Inc. You can contact them at the above URL.


    Good luck.

    Frank gives good advice.

    Some cautions...

    If you clean the machine use a vacuum, not compressed air - the compressed air will blow the target dust EXACTLY where you don't want it to go.

    Check the elevator for surface wear - it is covered with a rubber like compound that if badly worn can lower the birds at odd angles, which could affect flight patterns. You can remove odd pieces and be OK - if need be Shyda's has these 're-covered' with the rubber compound - it is an easy change out.

    Lube the machine too - the manual shows where (so many grease nipples, and the "U" shapes on the inside of the magazine, etc.)

    We keep a spare set of 'O'- rings at all times - for maintenance we install the spare set, and inventory the newly ordered ones. They should be fine for several seasons, but for the cost it's better to replace them. A slight nick/cut in one may change how the target drops. This will occur randomly in that the wheel on which they ride rotates with each target thrown. If the nick/cut contacts the target once in a while you have the answer to your odd high flyer.

    The elevators should be cleaned and re-dipped in liquid neoprene about once a year, depending on service. ThE other area to check is, aS indicated above, the brush pack. Keeping the machine clean and in good working condition will all but eliminate ANY problems with these machines. They are the BEST Automatic Trap Machines on the market, PERIOD!!!. If maintained properly, theY are like the energizer bunny.........they just keep going and going and going and going.......... We have 4 singles, doubles, and wobble traps at our culb and they really are bulletproof... Just our experience... Dan Thome (Trap2)

    Bob,

    QRP in Cleveland handles the newer style brushpack. It eliminates the brush screw adjustment. You have to alter the top of the holes with a countersink. This allows the use of 2 flat headed bolts. The brush pack is bolted in place from above and there is no movement. I made the modifications to 2 Superstars in less than an hour. I spent most of that time cleaning up target dust than actually modifiying anything. Send me a pm if you want more info.
