To enter last week’s Toolsday’s giveaway, you had to identify twin coil thing-a-ma-bobs in a framed contraption. We had a lot correct answers – most people knew they were hot-air balloon burners. We randomly picked one winner out of all the comments and that lucky person is tacokds whose guess of a gas-torch light was sort of right. Congrats tacokds, you have one week to reply to our email before we pick another winner.
Next Tuesday, we will be giving away a C.H. Hanson prize pack that includes 10″ Curved Jaw Automatic Locking Pliers, 7″ Locking Clamp and 7″ Needle-Nose Pliers. Each tool features Set & Forget technology, ergonomic handles, can lock on any size without adjusting and allows for simple one hand use.
Christmas is just around the corner. We’ve got fun decorating ideas and DIY projects for every taste and style including midcentury modern, coastal cottage, charming rustic, 60s retro, colorful bohemian and romantic traditional – find one that makes you merry.
To win the pliers and clamps, post a comment (click “comment” above) and tell us what this part (pictured below) belongs to and what it does. You don’t have to answer correctly to win; we will randomly pick one winner. 
On Tuesday, November 20, we will select the winner then start up a new giveaway for another tool, which will be given away the Tuesday after that.
You have until November 20, 2012 at 2:00pm (ET) to enter to win the pliers and clamps.






Looks like a chain pulley to lift automotive engines for an overhaul.

It is a derailleur/shifter for a chain on a bicycle. It gives the bicycle variable -ratio transmision. Bicycles have sprockets instead of actual gears. I had one of these break when I was on a long distance ride, halfway up a hill far from home:(
Rear Chain Derailleur: eliminates chain slap and the derailleur flipping forward, causing chain slack that leads to a dropped chain on the front chain ring.

I think it is similar to that thing that is lying on my garage floor from when my son took my bicycle apart….

It's a bike chain derailer, to move the bike chain from one sprocket to another.
