DIY Grip Strength Dynamometer (up to 150kg)

Men’s average: around 50 - 55 kg
Women’s average: 30 - 40 kg

Aluminum Tubes, Shackles Eye Screws, 2x2 wood, screws, bolts, nuts, T-Plate are all common parts that can be found at any hardware store. Sizing will depend on your design choices and requirements. For this model I used my own hand size to determine dimensions. The total project costs include only the materials used (left over material cost no included).

-Design Notes-

Result:
The grip dynamometer gives a result similar to the Grip X product I've been using so far with maximum results only varying with a few kilograms. From handing both devices I'd say that the cylindrical rough sanded aluminum tubes offer a much better grip than the plastic shaped handles on the Grip X, perhaps contributing to the higher reading.

Limitations:
This WH-C scale is rated to read 150kg while the Grip X only reads up to 90kg. Most dynamometers that read above 90kg are much more expensive than this project's cost. I've only reached up to 75kg and have had no problems with the durability but im not sure how it would hold up under 100kg+ pulls. Hopefully one day I will find out myself! The downside of this model is that the handle spacing is not adjustable like most devices. For a single user this is not as much of an issue as if it is intended to be sued by many users.

Future Goals:
I would like to make a similar design out of steel but so far I have no experience or equipment to fabricate such a device. This is not for sale and all credit goes to Gripmania and their GM- 150 for inspiring me to build a device for my self. Eventually I will purchase the 150 and compare models.

Thanks for this video.... I’ve been racking my brain trying to figure out how to make my own dynomometer...heck, I’m no mechanical engineer! Thanks

This is the video I’m looking for but i will choose steel frame instead of wood

Does the crane scale remember the maximum figure once it is achieved?
