Really using rebar for the slidy part?

Pinching your fingers between the hammer and the rebar gonna make you throw that tool through a windshield

I'm a bit spoiled, at my old job, we always had scrap 1/2 and 5/8 stainless or cold rolled bar stock laying around.

Tossing together a makeshift tool was a breeze.

I grew up around the Bethlehem steel literally every garage was packed with 1/2 round stock.

I’ve used threaded rod and stern bearings from a boat when I didn’t have an actual slide hammer. Worked well.

I’m all about making my own tools when I can, but they make many commercial versions of this.

No. It will be with damage. You need to "press" the outer race. All that on the inner race is what causes problems. Getting bearings out doesn't need to be careful. You're replacing them anyway. JFC! Never try to save the bearings you god damn potatoes!

If you are going to go all that way to make a tool, why not use smith round bar instead of rebar, or just goto Harbor Freight and buy.

The only thing even somewhat cool is using and expanding anchor for the grippy thingy.

Why is this better than just using a bearing puller.. Or just buying a slid hammer one if you want one? Not exactly expensive

"without prying or hammering" then proceeds to build a slide hammer to hammer the bearing out.

Gotta say “pause” before use 🤣

I have always used a socket the size of the outer bearing ring or just buy a slide hammer.

It broke the piece that was holding the ball bearing, it cracked to the right. Check the last second.

I thought I was the only one who saw that.

u/ozzyperry 2d ago

It was broke from the start but to the left

A blind bearing puller would be a lot easier and less likely to cause damage...

PINCHINGS! Give it a minimum of hand guard...
