Description

Restoration of a 70 year old Blackhawk hydraulic bottle jack.
This is their 5 ton model, in Blackhawk red, although there was almost no paint left on it. According to the Blackhawk tool catalogs I was able to find, this jack was manufactured right around 1949.

The restoration took about 20 hours not including video. Lots of very difficult to remove parts on this one. I made the handle because it needed one but I don't believe these jacks were ever sold with a handle.

Thanks for watching and please subscribe. I'll be posting new restoration videos regularly.

THE DECAL: Yes, you're correct, it's crooked. Hard to work around a camera sometimes. Literally "around" a camera. I didn't notice it until after the video was posted. SO, I've soaked it off and replaced it with a straighter decal :) Check out the instagram post for August 2 for a photo of the newer, straighter (used a t-square) decal. Thanks for watching!
