What are you asking? If your question is which one to use the answer is both. The TW-5 is 1/4" drive and the TW-6 is 3/8 drive.
|
Get one or the other and then get a reducer or expander thingey from Sears/Craftsman.
|
They measure torque in completely different ranges so you want to get the one you specifically need. For most people, I think that means the low torque model.
|
^ I did not notice that, but you are right.

It is not a question, but the answer. |

Just a reminder about torque wrenches. Industry standard is to not use any setting below 20% of full scale because the accuracy of the tool goes out the window below 20%. So the usable range of 10-60 wrench is more like 12-60. If you're going to use a setting below 20% of full scale, you might as well not buy a torque wrench at all. Keep this in mind when looking at poor quality torque wrenches that have a scale of say 10-1000. If you think you are going to make an accurate torque at say 50 with this wrench then save your money ... it's usable range is 200-1000. Determine the value you need to torque to and then use a torque wrench appropriate for the value. |

Actually, a usefull heads up about a product that is going to be released in February. Thanks Soil Sampler.
|
A review is useful. A link to a product is spam.
Woo a torque wrench. Nobody ever thought of that before. |
Park Torque wrenches up till now have been beam type. This is their first foray into preset style clickers.

fair enough, but hardly a new idea. I will concede if you're a big park fan and you didn't happen to notice it on the newsletter :p

There is a slight overlap in torque coverage (3-15 vs 10-60) so I wouldn't say they are "completely" different ranges. Other than that, I agree, you should use the wrench that best fits the torque you need to apply.

If the tool is properly designed you can use it through its full range. |
The TW-5 runs from 2 to 11 foot/lbs. Not real useful on a steel or aluminum framed bike. If you're not working on CF, get the TW-6. bk

I don't know what the original poster was after but I have had a question about these two wrenches for awhile. I think I need a torque wrench and I am a decent fan of Park Tools, can I get away with just one of these? And if so, which one? I will mostly be using this for home wrenching on steel frames with mid-range components. From the post above it sounds like the TW-6 is advisable.

What industry? :rolleyes:
The only way to know is to conduct a linearity study. If the tool is properly designed you can use it through its full range. Take a look at the SNAP-ON website. Look up your basic "clicker" torque wrench. Use QD1R200 model number as an example. Note that it has been certified to ANSI B107.14M-1994 and it's specs are " ... accurate to ±4% clockwise and ±6% counterclockwise from 20% of full scale to full scale." They will not guarantee any accuracy rating below 20%. Why?? Because SNAP-ON wants to sell lots and lots of torque wrenches ... especially to the government and government contractors. In order to do this, they must guarantee there wrenches to the same spec the "industry" must meet (ANSI B107.14M-1994). Is this overkill for torques performed on bicycles. Probably so. But ask yourself why you want to use a torque wrench on bicycles (or anything else for that matter). To apply the correct amount of torque. Without knowing the accuracy of the tool at a specific setting, how do you know you are meeting the torque specs for the bicycle. If that's the case, why use a torque wrench at all. I'm not saying not to use a torque wrench ... I'm saying don't "blindly" use a torque wrench. The advertised range of the wrench is not the only numbers you need to consider. |
