If you don't have washers on hand and just have to finish a project, you can drill holes into coins and use them instead. Use a dime or a penny for a small washer, and a quarter or half dollar to simulate a larger flange washer.

I wanted to finish building the brakes on my bike and I was no where near a hardware store so I just drilled through pennies. It worked great then, and the bike is still going strong!
This would be a great instructable if it were not for the fact that destroying a coin is illegal. (at least in Denmark it is) Sorry tho, cause it's for a good use.
<p>Maybe that is precisely one of the reasons why the lower value Danish coins have holes in them...</p>
which means the us could save half the ore costs of minting 17 billion coins per year by making the into washers in the first place #drjill
not illegal in the united states
Be nice. &nbsp;Don't destroy money. &nbsp;The moral of the story is washers cost a tiny fraction of a cent wholesale. &nbsp;Now look what Home Depot charges.&nbsp;
lol at the nickname hanson sux they sure do suck. there is nothing not nice about putting a hole in a penny. they have no nerve endings. i make beautiful rings for protection and luck from pennies and dimes. i do not put holes in them but i heat them up which if they could feel which they can't would hurt. i am actually being very nice buy making myself lots of money selling them and getting them lots of love and attention!!! of all the silly things i have heard being nice to a coin is the craziest. adopt a tree or a dog they do have nerve endings.
In the U.S it is illegal to destroy any coin worth $0.25 or higher. So no quarters or half dollars, only dimes penneys and nickels :)
I presume you've (all) seen the &quot;MAKE Money&quot; projects &quot;it's cheaper to make it out of money&quot;? Such as the wonderfully ironic <a rel="nofollow" href="http://www.make-digital.com/make/vol14/?pg=126&pm=2&u1=friend">piggy bank</a>?<br/>
This one is going into my mental toolbox. Nice, very nice. You get a +
Great tip... and so simple, it's genius!
They're cheaper too - when's the last time you were able to buy a washer for $0.01?<br/><br/>Reminds me of &quot;penny-weighting&quot;, a technique to make <a rel="nofollow" href="http://www.worldworksgames.com">cardstock buildings</a> more stable, by gluing a strip of pennies along the bottom. I've yet to hear anyone come up with a chaper and more convenient solution...<br/>
The hardware store I work at we have some washers for $0.01. Mind you they aren't really good metal like copper, and if you buy them in bulk they turn out ot be like $0.008 unit price
I do the same thing, except i usually grind them down with an angle grinder to the right size. I'm not sure if i like the new slideshow thing.
uh, yeah, a slideshow for one picture?
Why wouldn't you just buy the correct washer? They cost next to nothing and are available pretty much anywhere.
I use this a lot, but you might want to suggest to use pennies minted BEFORE the year 1982. Pre-1982 pennies are mostly copper (95% copper and 5% zinc VS 97.6% zinc and 2.4% copper) and copper will not rust like zinc.
Zinc makes great sacrificial anodes ;) In some cases, something has got to rust -- I'd rather it be the penny :p
wow, smart, and cheap! :-)
that's a cool new feature and a good idea for coins. woot!
