Wegc PBR AAR 2-15-15

Post by bcrich »

Today's match had a turnout of 23 shooters all in anticipation of shooting the mover that failed us miserably, the problem we had was the incline at the 300m berm... It was too steep at one end & time after time no matter what we tried it would derail from bumping the end of the track. Next time we will set it up on level ground. Sorry guys for having to scrap the mover stages.

Congrats to Aaron who took 1st place shooting his 6 creedmore with 385 pts
2nd place went to Bigg Joe H shooting his self built 260 with 347 pts
3rd place went to Henry G shooting his 6.5 Creedmore (I believe) with 341 pts
4th Soloman 333
5th Danny 327
6th Evin 317
7th Ben 305
8th Ray 295
9th Joe V 260 & takes top 308
10th Rich C 249
11th Michael V 248
12th Kevin 245
13th Netza 221
14th Julian 172
15th Bill S 170
16th Larry 169
17th Darren 152
18th Phil 109
19th Lou 99
20th Charles 76
21st Brett 72
22nd Ralph 58
23rd Heleodoro 33 & takes the FNG award. His first ever "tactical" precision bolt match.

Big thanks to James & Joe V for bringing you today's course of fire, also would like to thank Kurtis cold steel for bringing out his targets for us to shoot at... He's starting an AR500 target business & supports the local matches. These are the types of vendors that deserve our business! Thanks Kurtis big time!!
Course of fire was as follows however because of the mover failures we scrapped those stages.

Stage 1
5 shot drill (5 rounds)
300yd shoot-n-c
Scoring will be actual shot value per scoring rings
30 sec prep
30 sec shoot time
Shooters will begin in the prone with bolts back.
**on the beep shooter will have 30 seconds to engage their target with 5 rounds.
Evin & Netza damn near center punched their 320 yd target... Awesome job gents


Stage 2 **2 at a time**
Roof Top Holdovers (8 rounds)
100 seconds
70yd paper, 150yd popper flappers, 220yd 6", 320yd 8"
Starting port arms with bolt open and mag in.
On beep shooter will run up roof top and engage the targets in order from nearest to furthest with 1 round each. Then repeat. KNOBS MAY NOT BE TOUCHED ONCE STAGE BEGINS.
Aaron dominated this stage just like his confidence shows in the pic scoring 50 pts. That new barrel is a good one ;)

Stage 3 **2 at a time**
Barricade Movers (6 rounds)
60 seconds
12" mover steel
Starting port arms with bolt open and mag in.
On beep shooter will engage mover from each level of the barricade with 2 rounds.
(A hit on mover base = stage DQ)
Henry & Aaron both had 6 hits on the stationary mover for the highest hits. Outstanding display of marksmanship!!

Stage 4
Tresslers light box (5 rounds)
Time is determined by box
(alpha A, bravo B, charlie C, delta D, Echo E) from 70yds to 320yds.
A-70yd paper, B-150yd popper, C- tooth 220yd (blue) PBR steel, D- 6" 320 PBR (blue) steel, E- 320 paper
Starting standing behind rifle with mag in hand bolt back. When light flashes next to target engage that target before the next beep and light comes on, continue until all 5 lights have illuminated.
Joe V, Solo, Henry & Danny all scored 3 hits (30 pts)

Stage 5
Shoot N-move (8 rounds)
120 seconds
150yd 12" plate, 220 IPSC
Starting port arms
On beep shooter will move to orange cones and engage the target with 2 rounds from each shooting position.
Micheal Vic & Aaron both scored 6 hits for the stage high scores, good job hombres.

Stage 6
Earn your shots (5 rounds)(Pistol Stage 10 rounds)
120 seconds
Shooter must bring with them their slung rifle and pack with everything they brought in it that day.
On the beep, shooter will run from the starting line marked by cones and run to the blue barrel. The pistol will be staged on the blue barrel. Pick up your pistol and engage the steel pistol targets from left to right. Each pistol target must be hit x2 before moving to next target. Shooter continues until pistol goes to slide lock, and puts down pistol on blue barrel. Shooter then moves to rifle line and gets behind rifle and engages the hostage flapper at 320. The shooter can take as many rifle shots as the number of pistol targets successfully eliminated. -10 for hostage hits
Henry & Aaron once again prove to be well rounded shooters scoring 8 hits on this stage demonstrating their multi weapon skills :)

Stage 7
Nates house (9 rounds) (mandatory mag change **no more then 5 rounds in a mag** mag must come off your body)
100 seconds
6" PBR (orange) steel @ 220
Start port arms with bolt open and mag out.
On the signal shooter must crawl through the doorway and shoot through each port 3 times. None of the shooters body or equipment may stick out the back end of the box at anytime. Shooter may stick out the doorways. What ever the shooter brought in with him he must leave with (mags/brass excluded). If the shooter does not exit in time there will be a penalty. Shooter may opt to skip ports to get out in time. There will be a 20 second warning.
-30 points for not exiting in time
Danny did an outstanding job scoring 6 hits (60 pts) in the lil man house.


Stage 8 **2 at a time**
Prone mover (6 rounds)
60 seconds
Mover flappers
Starting prone with bolt back and mag in
On beep shooters will engage their target with 6 rounds.
(A hit on the mover base results in a stage DQ)

Stage 9
Positional (if time allows)

At first glance I couldn't tell who this shooter was but upon closer inspection of that bling bling watch on his wrist there was no questioning this man of class.... Non other than Mr Michael Victor ...great to have you shoot PBR
Image

Line pic of one of the squads.... Great to see father & son come out & shoot with us Larry & Heleo. Dad took fng award for his efforts giving some incentive for new shooters to come out & start shooting the discipline and not feel intimidated as we are all here for the fun times shooting with our friends & families

Thanks for coming out guys. We will find a level spot for the mover next time. We might have to sacrifice some yardage but the only other option would be to install brakes on that thing (not happening). 150lbs just gets too much momentum going down hill.

Thanks James, Joe V, Doug S and Rich G for an awesome fun. No need to apologize for the mover. Just being out there hanging with everyone is cool enough.

Congrats to the winners!

Fun match. Thanks again to Rich, James, Doug and Joe for putting the time and effort into making it happen!

James what about a spring shock stop staked into the ground?

It just needs flatter ground. On flat ground it passes a sensor, the motor shuts down and the mover will coast (usually about 4-5 ft on level ground) until it just about stops on its own, then the motor will reverse direction, the sensor is then inactive for 6 seconds so that the mover can pass that sensor again before reaching the other sensor on the other side of the track.

With the slope the mover would never come to a stop on the down hill leg before the motor would reverse directions. The wheels would just burn out and it would eventually stop and begin climbing back up the hill. Unfortunately this would take longer then the 6 second delay and when it would pass that down hill sensor again it would then reverse the motor which would send it to the end of the track on the down hill part.

The only solution is that it needs level ground so that it can come to a natural stop before reversing.
There might be a possibility of programming the motor to do some braking during the coasting phase but thats more of a question for the mad scientist.
Another option would be to increase the delay on how long it turns the sensor off for. The biggest issue with that is it probably is not great to put that much strain on the drive train with reversing the motor while its still hauling ass down hill since this otion does nothing to help slow it down any.

A shock at the end could possibly be made to help it but it would have to have a nice and long stroke to let it stop without derailing.

Level ground will solve all of this though as thats the only condition its been tested in before and it did great there.

The clean solution is twofold.
First, actively brake the motor.
Second, have TWO sensors, one for each direction of travel.
This is how real motion-control work is done.
The mad scientist will figure it out...

It's a gear motor driven through a relay so active braking isn't possible. Adding a second sensor doesn't buy you anything considering you couldn't stop the vehicle within the distance between the two sensors anyway, so the software algorithm still needs to ignore the return passing of the sensor.

Real motion control is done with servos. A servomotor strong enough to handle all that torque would cost twice as much as the entire project combined, not including the cost of the servo controller.

The most viable solution for the current design is a solenoid driven axel braking system............ Or level ground.

Its worked great both times we've tested it before on level ground. No use spending more money and redesigning anything jusy so it can run on a slope.

There's always a way.
You can add an enable/brake relay with braking resistors across the back side of the relay so that when you switch that relay from enable to disable, the motor is draining back across the braking resistors.
It will just need one extra logic output from your plc.
The enable/disable relay gets toggled just before you toggle the relays that are turning the motor on.

How much motor current do you need to control?
There are cheap transistor based motor controllers that do active braking without going full servo.

That is already how it is configured Randall. When the Enable/Disable relay switches power from the motor, the motor is dissipating its back EMF through a resistor and a bidirectional TVS to prevent arcing across the relay contacts. The motor open circuited, even with a high gear ratio still doesn't provide much braking on its own. It would take an external brake to improve braking performance beyond what it is now. Active braking certainly could be done using solid state relays instead of mechanical and driving the motor in reverse with a ramping PWM signal when changing direction to reduce stress on the gearbox. Don't really have time to mess with it at the moment though.

Gotcha.
If you want a cheap electromagnet that you could use as a track brake, look for old electric trailer brakes at a junkyard.
They have a pretty meaty electromagnet in them.
One of those magnets could be mounted to slide against the track and be energized for a couple seconds between your direction changes.
