Manged to hypnotise one once ...

It thought it was a chicken.

Feathers got caught in the chain. Never again.

some of the older blokes would happily put up with the extra fuel use to not have to stagger into the pub.

and before anyone suggests it, yes, i have already been to the patent office with plans for a gearbox with 6 ratios in reverse. simplest way round the engine running backwards issue i reckon. still some confusion with the gear lever tho'. will it be 1 down, 5 up or will it go 1 up, 5 down?

Forget it mate ...already been done...Italian Army tanks ..WW2..

DIY Magnetic Oil Drain Plug

---

Yeah, before you start to flame all over the place let me first make clear that this is quite possibly the easiest little project to complete. I'd also like to say that you can probably buy a Magnetic Plug on eBay or something for $5. I made my own because I am cheap, I like using power tools, and I like making things myself instead of paying for them.

So, you'll need:

- A regular Honda oil drain plug
- A Neodymium magnet (strong as ****)
- Drill press (or a hand drill if you're feeling frisky)
- Some kind of adhesive (ex. JB weld)
- Vice/C-Clamp
- Drill bits
- Micrometer (or just a ruler)


So, you have your drain plug. You'll first want to clean it up real good. Next, you'll want to punch a mark right in the middle for your drill bit to center itself in. VVV



Next, grab your magnets. The ones I used are somewhat small. They came in a pack of 10 for about $5. VVV



I used a micrometer to measure the diameter of the magnet, you can use a ruler if you like. These magnets came out to .3155". VVV



Next, find a drill bit that is about the same size or slightly smaller. I found a 5/16" bit that was about .0045" smaller than the magnet. I figured this size difference wouldn't matter once the drill press started vibrating anyways. VVV



Next, set up your drill press (or hand drill) with your 5/16" bit. You'll want to really clamp it solid so you can get your hole as close to the middle as possible. VVV







PUT ON SOME EYE PROTECTION!




Drill away! You'll want your hole to be roughly the thickness of the magnet. This part isn't crucial, you can have your magnet sticking out of the plug slightly, or even sunken in a bit. I figure it's best to have it flush, or sticking out a bit. If the occasion ever arises for you to clear the metal debris off of the magnet, you'll want to be able to do it easily. VVV



Blow off all of the metal shavings from your newly drilled hole. Before I continue, these magnets are probably strong enough to hold themselves in the bolt, however it's never a bad thing to be too careful.



IF YOU WANT TO USE ADHESIVE, DO NOT TEST FIT YOUR MAGNET IN THE HOLE! YOU'LL NEVER GET IT OUT!



Next, grab your adhesive of choice. I used a marine-grade adhesive that is very resistant to heat, moisture, and frigid temperatures. You can use JB Weld, or a similiar product. VVV



Mix some up! Equal parts of both. VVV



Cram some in your hole. Too much is not a bad thing, the excess will come out when you press the magnet in. VVV



It's time to place the magnet in the hole. My hole turned out to be a bit too small for the magnet to slip in under it's own power, so I used a small vice to squeeze it in. If you don't have a vice, you can use a C-Clamp.VVV



DONE! Not too bad for 10 minutes. VVV




STRONG AS BULL! VVV

I never seen any mention of filling in a JSEA or doing a start card let alone a permit to work
before starting this task.

No gloves either.

that is the exact reason i wanted to magnetize the bolt in the first place,
but apart from that, geez your a pesimistic bastard

That's what I have. Cost me a few $$ but it stays with me when I replace the car. Worth every cent IMHO.

Much better to put magnets of equal strength on the sump and rocker cover, works similar to newtons balls, you will never need to buy fuel again!
