Trap House Set Up

With a 200 foot tape attached to the front edge of the trap house, put a stake in the ground 50 yards straight out from the trap house in line with post 3. Take another tape at least 50 feet long and attach it to the stake and swing an arc with the 200 foot tape both left and right 45 feet away from the center stake. Put stakes in both these points. Hold a 10 foot pipe about 10 yards out from the trap house along the 200 foot tape and adjust your trap to hit that pipe at the limit of both its left and right movement. This will get you as close as you need to be without a transit.

LR,

Thanks for the diagram.
If I am reading the diagram right you should be 22' from the center stake on both left and right side on a arc.

Is that correct.

No, not feet...it's a 22 degree arc from the center pole. Take the 90 degree "L" as shown in one half of the field, cut in half to 45 degrees, then just about in half again to get 22.5 -ish degree arc. If that's clear as mud lol

Johnny, because you can't measure along the arc with a tape, you just have to measure across the arc the 45 feet. I think the length along the arc is like 50 feet so you just take the short cut across to get to the right point on the arc. It kind of like a long bow. The bow is 50 inches long but the bow string is only 45 inches long.

If you want a 22 degree angle use 58ft. Of course you don't need a tape measure to set an angle, especially if you want it just close enough, and don't use the front of the house as your bench mark. Use 1.5ft from the front of the outside vertical wall, to set your field. Also a 45ft chord on a 150ft radius would have approximately a 45ft 2.04 inches for the arc a little less than 50ft. Of course that might be minutia and I could be wrong.

17 degree/ 17.25

22 degree/ 22.29

A helpful idea. 10 yards out on all three lines, put a 3/8 piece of rebar about 12 inches out of the ground set in concrete that is level with the sidewalk of post 3. If the ground is sloping, use a 3 inch ABS pipe and pour the concrete inside the pipe with the concrete being below grade or the pipe being above grade to get level with post 3. You can then get 3, 10 foot, 1/2 inch electrical conduit sections. These will slip over the the piece of rebar making it really easy for one guy to set your target height by putting tape every 6 inches from the top of the middle conduit down to 8 foot level. By putting up the two pipes on the angle lines it is really easy to center the field and to center the trap to throw doubles.

Is it correct to set the angle for the targets to to stay within the 34 degrees?

Many traps are set to the maximum 54 degree angle.

Add a little wind and a slightly off angle bird ends up out of bounds.

Then there is always at least one prick or idiot that jacks up the speed to 60+ mph to screw up some practice rounds for people.

Please tell, where are these traps located? The ATA president will halt all shooting until rectified as was shown to Tucson a while back. Though maybe the new president will be a little more lenient.

That is the minimum field in which the targets are to be thrown, 17 degrees right and left of center. As you mentioned the wind blowing targets to wide, if the targets are set to throw the minimum in calm winds, a tail/crosswind will also lend the field to be to narrow for one or both target, but that appears to be acceptable to the ATA. Remember with ATA settings, the field in which the targets are thrown is considered at 15-20 yards from the trap, not at the trap.

That is the ATA minimum. On a G series Pat Trap there is a spreader bar that is 4 1/4 inches wide(34 8ths) being that every 8th of an inch represents one degree of spread. However, while this maintains the proper spread, it does not guarantee that the field is centered. You can only do that with properly set angles stakes. However, a quick check is that you can step in from post 1 and post 5 about 3 feet on the 27 yard line and sighting down that line through the 16 yard line a 17 degree target will appear to be a straight along that site line.

Remember, this isn't bench rest center fire shooting. Close is plenty good enough.

Thanks Guys,
This is on a private trap range and they only have one thrower which is a Pat Trap which has all of the adjustments on it.
Shotstop if I set the limit switches on the spreader bar at 4 1/4" will that get me close to the correct ata angle which =34 deg 2 hole target or do I need to set it at 5 1/4 which = 40 deg three hole target. I finally got the computer to print out instructions on the machine.

The good part about this location is that all it cost me to shoot is the cost of the birds and I bring my own birds that I purchase. Like having a trap machine/house at my home and it is only a five minute drive from my house.

Thanks,
Johnny

Johnny,

The 4 1/4" spread is a 34 degree field with tolerances. If it centered on post 3 it is +/- 17 degrees.

Now if you stand on the 27 yards line 3ft to the right of post 1 and it appears to be a straightaway looking at a point appox 1.5ft from the front of the house that will be a 19.4 degree target. That would be the 5 1/8" spread or close to it.

Of course you only write rules and comply with them with a close enough standard in sports. Eh, its close enough.

Added: Since it is a private range, you might as well set it up to be a little fun and challenging. Thus when attending an ATA event, odds or very high your practicing on angles you will not see in an ATA event. With the switches at the widest setting it is a 60 degree field.

That's inside the trap house, not outside.

True... very true. Just using the exact wording of the rule book I believe.

Point B is defines as the intersection of a line measured 1 foot 6 inches "from the outside vertical wall" (farthest from the shooting stations) of the trap house and the centerline of the trap house. Please review Diagram 1 on page 55.

You see shotstop the above was with the post you picked my words from. I would think they were self explanatory, I guess not. Thanks for the clarification, that probably was not needed. Your the best.

I will even add Diagram I. Though not specific as there may be traps out there that were set up as point B being 2.5ft from the front, the diagram clearly shows point B behind the front of the house as shotstop eluded to.

Image


But really, 1.5ft in front of, at the front of or 1.5ft behind the front of. It's close enough, right and that is plenty good.
