Lets look at the numbers in terms of something tangible:
The difference in weight between the two cords is about the same as 9 US Quarters. That is an amount you can easily feel. Try it. But if you add the weight of a tool (RO90, for example) and a hose, the difference is a lot less significant. With the lightest cord, everything weighs the same as 487 US Quarters. With the heaviest cord, the weight is 496 US Quarters.
If you are holding a tool above your head for 8 hours a day, then yes every ounce counts. In my opinion for the way that I use the tool, the inconvenience of having different cords far outweighs any difference in weight. And with the stiffness of the hose, any difference between flexibility of the cords impeding the use of the tool is not an issue.
I’m not saying Festool should not offer the slightly lighter cord, just that it should be an optional accessory like so many other specialty accessories offered by Festool.
This is how I came up with the numbers:
(from
http://www.usmint.gov/about_the_mint/index.cfm?action=Coin_specifications)
1 US Quarter: 5.670 grams / 0.2000034 oz
(from
http://en.wikipedia.org/wiki/Coin_wrapper)
1 Roll = 40 Quarters = $10
Weight of 1 roll = 8 oz
1 lb = 2 rolls = 80 Quarters
(from Amazon.com I couldn’t find weights from Festool)
18Gax13’ cord 14.2 oz
16Gax13’ cord 16 oz
Weight difference between cords = 1.8 oz = 9 US Quarters = $2.25
27mmx3.5m antistatic hose: 2 lb / 32 oz
(from Festool product manual)
RO90: 3.20 lb / 51.2 oz (without mains cable, with sanding pad)
Weight of tool + hose + 18 Ga cord =
51.2 + 32 + 14.2 = 97.4 oz 6.09 lb = 487 US Quarters = 12 rolls + 7 Quarters
Weight of tool + hose + 16 Ga cord =
51.2 + 32 + 16 = 99.2 oz = 6.2 lb = 496 US Quarters = 12 rolls + 16 Quarters
Sometimes I make mistakes. Feel free to get out your scale and calculators to check my results. I promise I won't take it personally. In fact, I'd appreciate it if you did.
