Too much play in the singletree?
In my new adventures of driving, things are going well. Had an experienced helper come and get us set up, and the horse is doing well.
Anyway, the single tree ends were bound with rigid metal bands on each end, instead of leather, and the bands were so tight, the single tree didn't actually swivel at all, and I know the whole point is to have some give for the shoulder movement with a breastcollar harness.
My husband removed the metal bands to replace them with leather, but the pivot point seems to have some extra play. I thought I'd ask before we messed with it, but there is not a screw/bolt that goes through the stationary bar all the way, and the single tree pivots fine, it's just that it wobbles forward and backward, as if the bolt end that holds it is perhaps broken? Yet it won't come off.
So the question is.. how do we check this or fix it without damaging everything? Can we just spin the single tree completely around to tighten or loosen it to stop the wobble then put the straps in place to keep in place? Or is the wobble a sign of extreme fatique and I need to get a professional to remedy? Or, is it normal, and I should just put the leather straps on the ends to stabilize it and go on. How much play should I allow in the single tree for the shoulders? My helper won't be able to come back for a little while and I can't find any info in the books I have.
Thanks in advance for any tips.
