thanks for your video, need to start working under my car but paranoid about the jacks coming loose! your video has really helped from a safety aspect!
I see one small problem with your methodology. Your putting all of the weight onto the cardboard. If you're preaching safety then you might not want to do that. Cardboard is slick. It's why break dancers the world over have been using it for 40 years to dance on. Weight and compression or not, still might not be a great idea to use. Same for the plywood but that's a porous material. It will spread the load but not as efficiently as a slab of concrete. Just saying. Good video though.
All jacks are inherently unstable, that's why you ALWAYS USE AXLE-STANDS. When used correctly on a clean, dry & level surface the bottle jack is extremely reliable on straight lifts. Keep in mind that the load may shift on higher/longer lifts. A round surface like a differential housing will sit secure in the X grooves on the jack-pad but as you get higher the load will wander away from the jack. Block it in stages or get a "Floor-Jack" - more $ but the wheels will self-center under the load.
:) thank you so much for this helpful video, nice work

I watched your video just to see where the jack would come in contact with the frame of the car and you didn't even show it

@jimmyoalfaro - Although the camera angle doesn't show it well at the beginning, it's very clearly seen at 2:57 through 3:26. Have another look.

Never used a bottle jack, I'm always scared it will topple over. How stable are they when used used on the axle and are up high?
