Semi-retired Posted June 14, 2013 Author #26 Posted June 14, 2013 I visited the metal fabricator who built the stainless steel cone to support my kitchen island counter top and posed the question about straps vs washers to adequately support my new luggage rack. This guy is 6ft and about 240lb. He stepped closer to the bike, lifted the rack out of the way and pressed down on the plastic.......HARD.....with one of his meaty fingers. There wasn't a millimeter of give in the lid. He said, "You say you'll probably be carrying loads of between 20 and 40 pounds back here? I just put 65 pounds of pressure in ONE spot (as opposed to the four I'll be using) and with my finger, which is less than HALF the size of the 1 1/4 inch stainless washers I suggest you use. You won't be breaking anything. Beware of OVER-engineering this thing." So he directed me to the bolt and nut supply guy around the corner who sold me 8 stainless washers (4 inside/4 outside) for 3 bucks! I'll cut circles out of an old inner tube to go under the outer ones.......and voila! Bob's your uncle. Thanks for all the sounding-boards, guys! Later``
Prairiehammer Posted June 14, 2013 #27 Posted June 14, 2013 . "You say you'll probably be carrying loads of between 20 and 40 pounds back here? You didn't REALLY plan on 40 pounds on that rack did you? Yamaha had a sticker on the G1 VentureLine racks stating a 10 pound limit. Just Sayin' And, how did you know Bob was my Uncle² ?

Flyinfool Posted June 15, 2013 #29 Posted June 15, 2013 You have to remember that there is a big difference between a static load and a dynamic load. It is easy to pull 4-5 Gs going over a bump. That 20 lb load just became 100 lbs.

I'll stick to packin wifey's lingerie back there (which I think is what she had in mind while "encouraging" this project from the get-go!)
