In order to make milking the cow easier, I built this head stanchion. The diagonal board slides up into place and when it's vertical, there is a 1-in hole drilled through all three boards. The front and back sandwich boards are 2x6s as is the diagonal sliding board. I had planned on sliding the board into place and then inserting a bolt through all three holes to lock it in place. She's too fast for me, and backs her head out knocking the board out of place before I can get the bolt through. I tried looking for spring-loaded plunger latches, but none of them are long enough or thick enough. I'm not married to the idea of using some sort of spring-loaded mechanism, but I will certainly entertain. Any idea that might make this easier.

Any ideas on how I can accomplish this? Thank you in advance
Have you tried giving her some hay or a little feed to help distract her?
Yes, I built a horizontal shelf that I put pellets on to get her in there. It isn't enough to keep her there while I slide the board though. Maybe I can try some apples? I just need to get her used to it and then it shouldn't be a problem. Hopefully.
Try to be patient and as gentle as possible. Low, soothing voice, strokes, nuzzling (between milking too, she's a friend). I found this, maybe you've seen it, it looks decent. It's been a very long time. Maybe enough hay to finish the job is helpful.
