After using the whizzer target changers at Bisley it was such an advantage for the shooters to be able to shoot in their own time during their booking period. Rather than shooters feeling rushed to finish as other shooters had already completed their targets and the targets needing to be changed for the next card.
After a bit of encouragement from someone who had made similar using patress boxes I designed a custom box and components to enable people to build their own and benefit from a safer range.
We run 8 at our range 21stromseyrifleclub.co.uk off of 2 x 12v power supplies.
Whats in the Kit
The 3D printed kit includes.
1 x Motor Box and Lid (This houses the Johnson 9v Drill motor, speed controller board and momentary buttons)
1 x Target carrier (The bit that runs on 2 cords either side and the cord which runs on the motor pulley wheels)
2 x Pairs of Target Holders (The upright elements that hold the target that slide on off the Target carrier and are easily replaceable)
2 x Cord Towers (These lift the cords up off the table)
2 x Cord Tensioners (These are not my design but are included in the pack foc and are used to tension the cords from the firing point when the targets start to slope to one side)
You will also Need to purchase seperately per kit (Lane).

1 x Pulley wheel for the Motor

DC Power cables (dependent on which power supply you opt for.
Small lengths of appropriate cable to connect from DC socket to Speed Controller, and from speed controller to Motor. (approx 20cm)
Length of Nylon cord for the length of your range, multiply by 4.2 (approx) to ensure you have enough per lane.
