Before I use the torque meister along with the torque wrench, there is a reading on the meister stating what ft-lb you should set your torque wrench at. How does the torque Meister take the length of the torque wrench in to account? All torque wrenches vary in length and size. |

The difference in wrench length doesn't matter. It is taken into account when they calibrate the scale of your particular wrench. |

I see. thank you |

You'll have to calculate the ratio of the TM and divide the required torque by that. |

Just use the chart they provide does not matter what size torque wrench you use although a 3/8" is more than enough. |

That's what I was thinking as well. Going off memory, on the actual tool, it's stamped in. I think it says for 230ft lbs, set the torque wrench at 25ft lbs. If I remember correctly |

The TM uses a 9:1 ratio. |

Chart? I got a used one anyone got a copy of the chart? |

Chart? We don't need no stinking chart. LoL.
I didn't have a torquemeister but knew the castle nut needed 240 foot pounds of torque. So one of my buddies weighs pretty darn close to 240 lbs. I marked the 1 foot point on my breaker bar and told him "stand here." Then to get the holes lined up on the axle I said "OK, now bounce a little...little more...little more....bingo."
It's not scientific, but it worked perfectly. No torquemeister or chart required. I don't know how that would translate into how much a person would have to weigh to stand on a breaker bar on a torquemeister. If you knew the ratio, you could figure it out. |

If it's 9:1 divide the required torque by 9 and the result is what you crank on the TM to. 27.7 foot lbs for a 250 lb axle nut for example. You might need an inch pound wrench for lower numbers. |

I’d be happy to make a chart.
$10 each, or $15 laminated! :lol: |

I’ve seen this 9x ratio stated in many places, but that is misleading.
It is 9x only for 109teeth flywheels.
For std 12v flywheels of 130 teeth, the ratio is 10.8 (130/12). Torque reading should be 23.4 lb-ft
For the axle nut - the sector gear provided has 24 teeth for 90deg of sector (the actual sector is a bit more than 90 and has 29 teeth. The small gear has 14 teeth. So the ratio is 6.86x (24x4/14). 253 lb-ft = 37 lb-ft on the torque wrench.
This is based on the version I bought about 14 years ago. |

Don’t use these things. Get a good breaker bar in 24 inch so you can feel the threads as you torque, and thus be aware of your work.
This is a non critical torque. It needs to be tight enough to stay on, and not too tight to deform the fastener. This range of torque is huge.
Using body weight and a bar is an excellent approach. It is funny reading people getting their panties in a bunch over trying to get the exact torque when you advance it to the next hole, which is a huge change in torque. |

I received the Torque Tool (from Chirco in Tucson) a couple of years ago as a gift from Mrs. Cusser. It has the torque settings on it.
Funny - haven't had need to try this yet !!!
In the past, I just used a 4-foot pipe on a 1/2 inch Craftsman breaker bar with a 36mm socket. Later on I borrowed the 250 ft lb torque wrench from O'Reilly.

I got one of these off ebay for £70-odd a few years ago. The guy didn't know what he had.
It's rated for just under 2,000ft/lb output :lol: :?
Retail price new:- around £900.00 :shock:
It's a bit clumsy but deals with flywheel gland nuts and rear axle nuts with ease. |
