22 April 2020DIY Shimano hollowtech crack holder tool
This is one of my favorite DIY tools to use. It is very easy to make, very cheap and very useful. The tool fits all the current Shimano hollowtech cranks and it does not scratch them.
I always use this tool when I replace the chainrings of the Shimano hollowtech cranks. I clamp the tool on a bench vise and then I place the cranks on it. The tool holds the cranks steady as I unscrew the bolts to change the rings. The crank shaft seats on the bearing and I can twist it so that I have easy access to all bolts.
How I made the tool
I made it with used parts and it did not costet me a cent but if you buy all the parts that you need it will cost less than 6euro.
What you need to make the tool1. A 20mm diameter 15 cm long wooden rod
2. A 8mm diameter 20 cm long aluminium Rod
3. A 22mm outer diameter and 8mm inner diameter bearing.
