 Posted: 11:51 - 02 May 2012 Post subject: Circlip made from safety pin? |
 |
|
Hi all!
Just curious, one day i lost a circlip from a piston (luckily i found it again!) and i thought about making one from a safety pin. I mean, that stuff is similar width and if you could get it the right shape, it'd work, wouldnt it? Or should you just use a proper circlip?
Just wondering  |

Why make something that could cause a catastrophic failure of the engine that only costs 50p new ? It doesn't make sense  ____________________ Space Is Deep |

I was never under the impression that you'd actually done it; I was voicing my opinions of the idea itself.
OK - let's try and go through this in a civilised manner. For starters, you're on BCF, a forum which is known for acidic humour. Secondly, quite aside from the whole 'slipping out' argument (which is valid), you've got the fact that you'd hypothetically be replacing a machine-manufactured (i.e. high-precision) piece of metal with a hand-bent length of what's effectively wire.
Aside from being a different cross-sectional profile (so it wouldn't even fit properly), they're also different grades of metal, and have been subject to different treatments. I'm not a metallurgist, but there are some members of BCF who are, so they'd be able to give a more detailed reason as to the whys and wherefores.
More to the point, it's inferred that it's the circlip that retains the gudgeon pin - if that fails, you've got bigger concerns than getting a bit of safety pin in a port. Specifically, a lunched piston, bent conrod - lots of shrapnel being thrown about inside the engine, causing the thing to have a terminal seizure.
We've all had silly ideas at the age of fifteen, and I'd imagine that we all got slapped down because of them. I know that I certainly did, and if my teenage daughter came out with something as silly as the safety pin suggestion, I'd devote some serious energy to mocking her for it, too. More so than I have done here, at least.
As a rule of thumb; until you're well-practiced at bodgery, stick to the principle that if it's structural, MOT-able, or attached to an important internal, it's not bodgeable. When you've got some experience under your belt, these strictures can obviously be relaxed, as is appropriate. ____________________ '10 SV650SF, '83 GS650GT (it lives!), Questionable DIY dash project, 3D Printer project, Lasercutter project |
