I recently replaced the western rigging on my saddle with these (http://www.ridingwarehouse.com/Mad_T...-MTBCFRBS.html). I love the extra stability and girth position. However, they are held on by Chicago screws. I went on a short ride today with 8 screws in place and tightened. Ended the ride with 7 screws. I would like something much more secure, especially as it is holding my girth on. If possible, I'd also like minimal/no bulk under my leg, so no bulky fasteners. Any ideas ?
I second the lock-tite. There are two different types. One is very permanent and the other is slightly less so. I have not needed to use the "permanent" version. I also put converters on my endurance saddle to switch to using a dressage girth. the semi-permanent lock-tite has kept the chicago screws in place for years.
In a pinch, nail polish on the threads will also work.
Totally understand--I no longer own anything with Chicago screws or trigger snaps because they're so unreliable. I second taking it to a saddler, but I'd go with sewing on billets. Rivets can pull through, and do it without any warning.
