filling bored holes in concrete

[El Cazador]

If the guy will sell it, I'm upgrading compressors. So I'll probably have to drill new holes to keep it from dancing across the floor when it's running. What can I use to fill the three holes that will be left from the old one? Something I can buy in small quantity since the total volume will be so small. Tks.

CORE-ROCK , find it at Lowes or HD

If you aren't worried about someone stealing your compressor, you can usually put it on wood blocks and shim it and it won't move. Takes about 15 minutes to find out if it'll work- couple of 2x4 scraps and a shim or two under them. Lot easier to move later that way, for maintenance or whatever.

Get some compressor pads. These install under the compressor and will take care of any vibration issues.

Mines still bolted to the crate it came with, hasnt moved since unless I push it around with the bobcat

I've got the present one set up outside the garage to cut down on the noise inside the garage. It works - sorta. The idea of insulating the compressor from the concrete sounds good b/c the vibration is of course transmitted through the concrete into the garage. But it's not going to move at all when bolted to wood blocks or putting the pads under the feet? What about the steel air line from the compressor? That doesn't get abused? Suppose if it stays in place it wouldn't.

Mine, and the ones I've dealt with (auto painting for a few years) didn't move if the weight is distributed to all the legs evenly and dampened. The one I have now walked several feet when I ran it the first time to test it. Put it on a couple of blocks and shimmed it level and it's rock steady and much quieter. No matter what the setup though, you should always have a flex line on the compressor running to your hard line. That will reduce noise and breakage potential, and make service easier.

I love demonstrating my ignorance! What kind of flex line should I use. PSI won't be over 150. Thanks! Vic, Redlands, CA.

Any high-pressure hose will work, best if it's as big or bigger than your hard line. Because it's a short run, like 24 inches, it can be smaller than the hard line within reason, especially if you're running 3/4" hard line and no air-driven jackhammers. I've seen steel braided lines used, probably to minimize expansion to help the hose last longer. I've seen braided lines at Home Depot for use with water heaters, there's no reason I can think of that they woudn't work for air as long as they're rated for enough pressure. I would put some threaded male ends on both the compressor and the hard line, then had-tighten the hose on and check for leaks before using a tool to tighten further if necessary. You can also just throw some hose barbs on the comp. and hard line and use a piece of air hose.
