A question for any of you guys that have installed your MaxJax or M-6: I'm trying to follow the instructions for the assembly of my M-6 starting with the hydraulic fittings that attach to the base of the cylinders, and I found that according to the instructions that I'm supposed to use two 45...

I think I'm getting there with the bolt-in-and-go mentality. Thing is, I have worked under lots of lifts in unknown situations without any real thought on its worthiness, mainly because all of them had been installed and used for some amount of time prior to me getting under them. My main fear...

In all seriousness for a minute, how big a sledge hammer? Short handle, long handle? I gave it a shot with the 3 lbs. short handle sledge I have and it made a divot in the surface, maybe 1/3" deep, chipping off just the surface.

I like that idea, but talk about "destructive" testing! :lol:

It's posts like yours make me love this forum.

I did not know that. If that's the only real concern, I'd gladly pony up for the cost of epoxy anchors if that's all it is.

Oh boy... ignorance really is bliss! But yeah, don't be stupid, should be okay, right? Reminds me of that quote going around these days: "Play stupid games, win stupid prizes." Applies here too.

Yeah... not what they quoted me. I'd gladly pay $100-$120 for a core sample test, but the locals quoted me in the $300-$400 range with them drilling the core. And thanks for the info on the core sample size. Good to know.

They both said 3000 psi pour is very common in my area. Combined with the good condition of the slab and and the typical increase in hardness over time that concrete gets, they felt the slab would likely exceed that 3000 psi minimum.

Again, thank you everyone for your replies. What I'm getting is most people don't check at all, a few do, and at least a couple just poured a new slab. Where does that leave me? I'm kinda wishing I hadn't asked now, but should probably be glad I did. I just wish this kind of safety thing was...

BTW, the slab is in very good condition overall. No surface flaking or cracks. Not missing major chunks or anything. Still measures very level (not more than 1.5 degrees of slope any of the 18 different places/ways I tested).

Thanks for the replies. I kinda suspected most folks don't have the slab tested for hardness before installing their lifts themselves. But I was kinda surprised that none of the "professional" lift retailers/installers in my area even offer a hardness test as part of their $100-$130...

First, please forgive me for starting this thread. Trust that I've searched and searched and read and read trying to find a tip on where to find someone to do a rebound hammer test on my slab. I've called several local lift installers, several concrete contractors, tons of tool rental places...

Well, I was completely wrong... on several accounts. First, the proper number for the ones I bought is 44992. Second, the 33442 and 44992 are identical sets of the thin profile ratchets. Third, I got my 99442 set and it is all marked as being US made. Why Sears sells the same set under two...
