I bought a MR-1 from someone and they used garage floor epoxy first and from the looks of it, the floor epoxy didn’t cure properly and cracked, so they put marine epoxy over what was cracked out and the marine epoxy (so said it was marine epoxy) didn’t take to it.
I was able to start pulling chunks out both epoxies and expose the concrete. I have some epoxy on the way to redo it…..does anyone have any tips on how to somewhat easily remove all this.
You got an air compressor and a cheap air hammer? Thats what id do. May take the top layer of concrete off but itll work
I agree with @salemlakesarmory. What a mess you have on your hands. What the hell was this guy thinking? The epoxy is less than $100. An air compressor and an air hammer.
I just wanted to add another thing. Before you repour more epoxy make sure that machine is squared away. If they took a shortcut on the epoxy who knows what else wasnt done right. Those are newer drain style so its 2024 and up so not that old. Also that concrete looks suspicious, they may have dry poured it and in that case id break it all out and do it right.
It would just suck to repour and then find out something else that is bad needs to be fixed that would require you to remove the concrete.
You have your hands full. That concrete looks terrible! I wouldn’t be surprised if it falls apart.
Update this? Im curious how its going
I posted a reply the other day, but it never came through. I pinged the concrete listening for hollow spots and cracks, none found. If I have to bust the concrete out later down the road, I will just cross that bridge if i get there. We you @salemlakesarmory suggested an air hammer, I went straight to the freight and got the mini air scraper and that worked great. It took a little longer, but had more control over it. I poured the correct epoxy Thursday afternoon and the flood coat. Running 2 dehumidifiers in the garage helped out a lot on it curing.
I went with a blue pearl.
Blues a great choice, i went with grey and sorta regret it. Hard to see chips sometimes. Looks great though
Got it up and running. I am resurfacing the base plate. I found the rails bolts weren’t even touching the bottom of the screw hole, so the spindle was rocking back and forth. You can see where it was chattering when he was surfacing. The sad thing, he was trying to tell me how to machine, I am a machinist by trade……really. Oh well, lesson learned. Next time if I don’t like what I see, I will walk away.
Hopefully you got everything assembled correctly now.
Luckily, the base plate is pretty thick. Keep us posted
@Bigdaddy2166, will do.
You rescued a good machine from a bad environment. Imagine how abused it would have been had he decided to not sell it.
I saw this video and said I had been there. I remember cutting my MR1 plate several years ago with my butt cheeks squeezed together. 
That’s usually how it goes.
I’m glad I used some sense and checked tram, rails, and all.
Side note. If you are in the south like me (I-10) running a dehumidifier/s in your shop or garage helps keep rust off your machine/s. My humidity stays around 45% with the doors closed.
Just adding in my two cents for the ones that didn’t know.
