Thread: Fly Wheel

no wet sanding it with water and wet/dry sandpaper will get you out of trouble. wipe it down with brakeclean afterwards.

ok thanks for your help, will get onto that as soon as possible.

I'm told by a reliable source (my brother the farmer) that a light mix, about 5% molasses to water is good for cleaning up surface rust also. I think it is the active metal cleaning constituent in Coke. You can get it at Produce stores apparently - I think there is one on Gympie Rd at Lawnton.

I've not tried it yet but intend to shortly as I have a lot of bits that have been "sitting out for a while" (about twenty years). Wet and dry is probably all you need but.

Cheers

Mollasses works but takes a while. Coke has a PH of 2.3, extremely acid, due to all the polyphosphoric acid in Coke. Phosphoric Acid is the main ingrediant of Rust Converter, which you use watered down when you buy Rust Converter. Do not know if Coke need to be watered down, but would think so.

Just a side issue, in the western world we have a hugh problem with Osteophorisis. In another previous post on a different thread, I showed that Milk is a major cause of osteophorosis, the countries with the highest milk consumption having the most osteophorosis, due to the fact that Cassein, the protien in cows milk requires an enormous amount of calcium in order to digest it, the body robbing that calcium from the bones in order to digest Cows milk products.

Soft drinks like Coke which are so acid require large amount of calcium taken from the bones in order to neutralise that very strong acid. So only use Coke to convert rust, not to drink, if you want healthy bones.

Just to keep completely OT... by ostephorosis Im sure you mean osteoporosis.
Demographic arguments for specific cause and effect relationships are often spurious.
Im sure the same countries with higher milk consumption have higher GDPs... does drinking milk make you wealthy? Some recent peer reviewed research on dairy and bone density:

"Effects of gender, alcohol, smoking, and dairy consumption on bone mass in Wisconsin adolescents."

Source WMJ. 108(4):181-8, 2009 Jul.
CONCLUSIONS: Alcohol or smoking had a significant negative effect on bone density, whereas adequate dairy intake (>4 servings per day) had a favorable effect in Wisconsin adolescents. Sex differences in bone density growth were clearly identified, with males tending to gain BMD and females tending to lose BMD by year 4.

There was an apparent interaction between milk and exercise in BMD at the heel, spine, hip and tibial mineral content and cortical thickness. Our data confirm the importance of race, body size, milk intake and duration of weekly exercise as determinants of BMD and bone size.




Anyway, have a loverly day... hmm I wonder if I could bill the Australian Dairy Industry for the 15 minutes research I have just done

Crikey! All this over a bit of surface rust on a flywheel. Actually it's all interesting.

I particularly find it interesting that Phosphoric Acid is the active constituent in molasses as I currently use it in the form of a product called Plus Rust Converter (don't know if it's still available but it's a good product) and as straight Phosphoric Acid (available from paint suppliers for preping steel car panels before painting).

I often soak thing in the Plus converter particularly to clean them up but I occasionally leave them too long and end up destroying them. I think that is why the idea of the molasses appeals as I should be able to leave thing soak longer without having to go back every five minutes to check.

Having had my 76 shorty in bits for many years I have a lot of mechanical bits with surface rust that will need cleaning up. Figured the molasses would be good for them.
