Inspiration courtesy of Steve at Woodworking for Mere Mortals. That link has free plans so you can make one yourself.
I didn’t follow the plans to the letter, I watched the video once with my daughter and just kinda winged it from memory, so astute viewers might note that a few details are off. When my almost five year old is “helping”, I don’t exactly have the same focus and time to make something with the level of workmanship I usually aspire to.
But she loves it, which is what matters. She can nock the cord and pull the trigger herself with no problems.
