Snap On Rebuild Projects - Pics

[bigredjeepone]

I thought I would share a couple of the Snap On Ratchets I have rebuilt.

I am including before and afters. The 936 had that coating that Snap On offered at one time, looks like chrome to protect the chrome, but is evil as evil gets. Flakes off and gets under your nails. Took 2 hours to get it all off.

The TH737 was rusted almost solid at the head but cam out better than expected.

Still struggling with keeping the handles perfectly clocked when pressing them on though.

That is the damaged chrome (chromium), the undercoating is nickel...that tool is trashed...

FYI, bare nickel has potential health issues....just look into that as I believe the topic is somewhat controversial .... as skin/nicket contact is more likely....its probably riskier on a ratchet handle than some other places it tends to show up (like cheap cman sockets).

edit: you can see how the nickel plating is darker than the chrome, which can be a/b tested nect to another tool, under daylight.

good luck.

However, this coating is more silver than chrome. What's under it looks like any other ratchet I have. It became very apparent when I put polish on it. The coating turned a darker silver and the layer under it brightened as chrome should. Another reason I am almost positive it isn't nickel showing is the fact it is very hard. I used a razor to scrape the coating off and it never phased the layer under it. Unless chrome plating is different that what was used on firearms, it would have scratched.

Also, I have not seen the chrome peel off a newer Snap On ever. Older stuff was as bad as MAC and Craftsman. But I am wrong a lot . . .

As for health issues, I am not worried. It has a cushion handle and when I work I am almost always wearing nitrile gloves. I guess I can't lick my tools anymore dang it!

OK as I was typing . . . I was just informed by one of the guys here, that looked at a sample of the peel, that the ratchet was, as he put it, powder coated by some F@#$ing idiot.

I'm thinking the tool is fine...nice job.

Quoted from the Agency for toxic substances and disease registry:

The most common harmful health effect of nickel in humans is an allergic reaction. Approximately 10-20% of the population is sensitive to nickel. A person can become sensitive to nickel when jewelry or other items containing nickel are in direct contact and prolonged contact with the skin. Wearing jewelry containing nickel in ears or other body parts that have been newly pierced may also sensitize a person to nickel. However, not all jewelry containing nickel releases enough of the nickel ion to sensitize a person. Once a person is sensitized to nickel, further contact with the metal may produce a reaction. The most common reaction is a skin rash at the site of contact. In some sensitized people, dermatitis (a type of skin rash) may develop in an area of the skin that is away from the site of contact. For example, hand eczema (another type of skin rash) is fairly common among people sensitized to nickel. Some workers exposed to nickel by inhalation can become sensitized and have asthma attacks, but this is rare. People who are sensitive to nickel have reactions when nickel comes into prolonged contact with the skin. Some sensitized individuals react when they eat nickel in food or water or breathe dust containing nickel. More women are sensitive to nickel than men. This difference between men and women is thought to be a result of greater exposure of women to nickel through jewelry and other metal items.

People who are not sensitive to nickel must eat very large amounts of nickel to suffer harmful health effects. Workers who accidentally drank light-green water containing 250 ppm of nickel from a contaminated drinking fountain had stomach aches and suffered adverse effects in their blood (increased red blood cells) and kidneys (increased protein in the urine). This concentration of nickel is more than 100,000 times greater than the amount usually found in drinking water.

Well just called Snapon and they said you guys are correct, it is the chrome. They are replacing free of charge.

It would be nice to read the discussions about tools without getting all worked up. If I want to get worked up, there's other sites for that. Just sayin'.
