120v Impact Wrench Modified to Operate Car Jack

About: Update 12 September 2017: A very special thanks to Sam Elder, a manager here at Instructables, who tracked down the cause of my lost publications and fixed the issue. Take a bow Sam!

Intro: 120v Impact Wrench Modified to Operate Car Jack

I converted this 120v impact wrench into a scissors jack operator. The kawasaki wrench never worked properly and it was about to be thrown in the garbage after years of storage.

Step 1:

The universal motor in the impact works great off DC. I housed a DC DC boost converter in an old drill battery case with cooling fan.

Step 2: Completion and Testing.

The impact is powered off 90vdc, uses 400watts and raises the car pretty well. For the test I used a portable lifepo4 battery but for a tire replacement on the road, I will plug the xt60 connector into my car's power system.

Not bad for an old bogus tool to be repurposed into a useful application.
