Re: Wheel weights/Good buy!
Good question, Harv.
I was wondering the same thing about the (similar but different weight) limits shown in my 4700 manual.
Maybe it has to do with all that mass tearing out the 4 "bolt-hole" attatchment points thru the wheel "web"!? It seems that "impact" loads from bumps, etc., could cause some terrific stress on that 3/16-1/4 inch metal.
Any other ideas?
I've got some 4' thick x 12' square blocks of tool steel (!) that I'm planning to make mounting brackets for.
Each weighs 180 lbs. Plan to put 2 (360 lbs,) on each rear wheel.
They will still be inside the wheel-recess, and so won't "stick-out" to snag things. [May just use 1-per-side, though, since the specs. call for a max of 2 (110 lb) wts., or 220 lbs. per wheel. My tires (Michelin XM27) are already 75 lbs (each) heavier than stock R1s, so with one block I would have 255 Lbs. /wheel over "stock".... probably should stop there!]
Got them for <25 cents per lb. at Boeing Surplus in Kent, Wa., near Seattle. Such a deal!! /w3tcompact/icons/laugh.gif They had about 10 left as of 2/3/01. ...weren't moving real fast!
The guy said it was worth about $5 per lb. That's about a 95% discount. Seems Boeing wastes nearly as much money as the US govt.
Have 4 additional to use for front or rear-mount
ballast (720 lbs.)...or 6(1080 lbs.) if I only use 1 on each rear wheel. Any extras make great "anvils" or killer-supreme paperweights! /w3tcompact/icons/shocked.gif
(Also picked-up 3 welded 2x2 box-tube metal work-bench frames-to-kill-for, 8 ft. x 3 ft. x 32" high (no tops), painted, wired for elec, plumbed for air, that must weigh 400 lbs apiece, for $15 each.... they've got a heck of a salvage yard!!)
It pays to look around!
