Re: Southern Yosemite Rebolting - List of Completed and Most Needed Projects

thx will do

Any thought on extending the length of the handle to make the stroke 'easier'?

Watch the first video with the hydraulic tool.

The mechanical tool with short handles develops enough force, up to 5000 lbs, to break rusty old 3/8" bolts so longer handles won't do anything but make it harder to carry around.

I thought I saw your meter only hit just over 4k?  That's a lot for most cases, but to pull a brand new retro in wilderness might need more, yes?  What's the PSI for granite?

Once you get the groove ground into the cone, it usually only takes about 1000 lbs to pull the bolt out. The groove keeps the sleeve from expanding over the cone so they pull out with roughly the force it takes to pound a bolt into a hole.

ah, ok, that's beginning to make sense to me. Practical application over seeing it online effect.   thx!

This is really great what you are doing with this, Dan. I can think of plenty of Soyo 3/8" bolts that need replacement in wilderness and otherwise. Many were placed in too-shallow of a hole and sticking out dangerously far (probably due to desperate-situation ground up placements) and plenty of non-stainless bolts too.
