Harbor freight air/hydraulic engine hoist conversion (flat bottom jack)

[chevyracer56]

Hey there, as with most people I like to save money where I can . Today's project consisted of modifying a $40 ( $32 with coupon) air/hydraulic flat bottom jack into the equivalent $80 jack for use on my engine hoist.

The only differences between these two, at least that matter to me, is the flat bottom one is not a direct bolt in for my HF engine hoist. So I decided to use my HF bandsaw, cut off the old flange and weld it onto the new jack. Keep in mind I was not terribly worried about perfect penetration since this part will remain in compression under a load.

Anyhow on to the pictures (forgive cell phone quality)
