For those who asked, here's what the attachment part looks like: <https://lh6.googleusercontent.com/-_LfrF0BfykU/VCxC4ADtbOI/AAAAAAAAB5k/A0T7a8HZv34/s1600/IMG_5466.jpg> <https://lh6.googleusercontent.com/-LP-fQ_BcmQg/VCxDCIu9QjI/AAAAAAAAB5s/-1YKfAU3Igc/s1600/IMG_5468.jpg>
It's really straightforward, just a metal sandwich. I tapped the back plate for the 5mm screws, but I could just as well have used nuts. I really just wanted an excuse to buy the tap, but of course it also makes installation a bit easier. As you can see from the first shot, there's a bit of bowing going on in the plates because I probably tightened the screws down a bit more than I had too. I expect that in time the plates may bend a bit more and thus loosen but I'll cross that bridge when I come to it. In truth, I'm looking forward to working out the kinks and improving the design. Thanks to all who gave a thumbs up :) On Saturday, September 27, 2014 4:12:41 PM UTC-7, jar351 wrote: > > I was pretty psyched when I bought a used Saddlesack bag from a fellow > poster here last weekend.
