Yeah, I know welds can and are used a great deal in structural components. The aerospace company I worked for specialized in welding. It was a tightly controlled process and depending on the welds, they were dye penetrant, x-ray, ultrasonic or used other methods to 100% inspect the welds. Of course I would trust those welds. Mass produced stuff in China... not so much.My dad was a welder for most of his adult life. You do realize that the huge beams under the highway overpasses you drive on are welded fabrications?
Anything produced with lowest cost as job number one will fail....welds, castings, electronics, batteries.Yeah, I know welds can and are used a great deal in structural components. Mass produced stuff in China... not so much.
cast aluminum jack stands, which is no guarantee either, as casting defects are a real possibility.
Never got under a car again without 2 or 3 layers of protection.
I liked the idea of ramps too, thinking they were safer. Did some research and found out the cheap plastic and cheap metal ones can be worse than jackstands. I found that by the time you spend money on good ramps, it's a lot cheaper to get good stands. And since I'm pretty cheap... Also, need stands for tire rotation anyway.If I get under a car, it is on ramps. Never get under a car that is not on its wheels.
I have my dad's old oak ramps. They worked for his Dodge pickup, my mom's Hudson opera coupe, their Kaiser and Ramblers, my MGA, my Sentra, and now our Bolt.I liked the idea of ramps too, thinking they were safer.
The only time I've ever gotten underneath a car, I drove it up on a curb on 2 wheels. I was a poor college student and didn't have any ramps or stands. After that, I decided I would just let a professional shop handle anything that needed someone to get under the car.Anything produced with lowest cost as job number one will fail....welds, castings, electronics, batteries.

Yes, they’re “rated”, but I’m saying this because I saw one fail right in front of me in my driveway. And ever since that day I will never use a scissor jack - except sparingly, in emergency situation, out on the road. At home, I use a floor jack. Way back when, I didn’t own a floor jack, and thought I could just use the scissor jacks from my multiple cars - after all ... every vehicle was bought brand new, so the jacks were all new.Sooo many cars that have spare tire come with scissor jacks that are rated to lift one corner of the vehicle. I would trust it.
Never heard of that, but I suppose it's possible. I have a VW scissor jack that I pulled out of a 1995 Jetta when it got totaled. These jacks are affectionately known as a "widow-maker". Not from the nut failing but from improper alignment during use. It looks like this:It’s the threads in that block that can fail
Your dad was a well paid professional, not slave labor in China so I trust his welds a lot more than I trust the welds on a Harbor Freight jack stand.My dad was a welder for most of his adult life. You do realize that the huge beams under the highway overpasses you drive on are welded fabrications?
I wouldn't trust anything from Harbor Freight. Thankfully, I am old enough to have a complete collection of tools, and appliances that were built in the US, when it still had FDR era laws.Your dad was a well paid professional, not slave labor in China so I trust his welds a lot more than I trust the welds on a Harbor Freight jack stand.
It is about safety, and saving myself the time of sitting for hours on the road for roadside assistance.100 lbs
