That's what I was trying to say. The rub arises when one person's 'sensibly' conflicts with someone else's.. . .It's wise to use that head to think, then act sensibly.
I did the same thing.My first real compressor was old and free, fired it up and it had pinhole leaks in the bottom, in my ignorance I welded a big patch over the bottom. It was bolted to a slab behind the shop, ran for 2 years before compressor died, did not blow up, nobody dieded. YMMV!
I put a timer on mine. Best money ever spent. It's literally a $20 timer switch you get at lowes. 5 minute, 15 minute, 60 minute, "on". I then wired it to a 240 volt contactor which feeds the compressor.I am always careful that the compressors are off when I leave the shop for this reason.
No problem! I just used one of these boxes to hold the contactor, stole a leg of the 220 and ran it to the switch. If it were three phase, I'd wire it directly to the motor starter, but this is a home shop environment, 240 single phase compressor.Thanks for that.
I could use something to simplify my shutdown list when I leave the shop.
I occasionally buy, repair and flip compressors. Mostly with tired pumps. In my experience the pumps don't wear out usually the valves go bad. usually a bit of lathe or surface grinder work or maybe a spring replacement or two brings them right back at no cost. I always hydro test to 50% over tag rating. Easy peasy.I was wondering what the general opinions are on buying a used air compressor?
Pretty much all of my tools are bought used as my preference is to buy quality used tools versus cheap new ones.
I need something primarily for sandblasting which I think puts me in the 5hp 60+ gallon tank range if that sounds about right?
When it comes to air compressors I can find a lot of nice ones in the area at reasonable prices that meet my needs, however tank condition always makes me nervous.
I see all few of the older USA made brands available locally which one would think may have thicker tanks than our modern value engineered ones. I even have a brand new 5HP compressor duty motor lying around in case I need it. However it all comes down to the tank being safe. Any thoughts on inspecting one? Maybe it's time to get a boroscope too will they be useless looking inside at determining how bad any likely rust is?
I may hold the record for the oldest working compressor in captivity. I have a Henke Pacemaker (Kellogg American) built in 1965. It's been in the shop over 30 years. When I purchased it I also bought a couple rebuild kits thinking I was going to need them at some point in time.
The compressor doesn't get used on a daily basis but more as a backup when times are busy. It gets regular maintenance and draining, and so far, hasn't needed anything more than some valves and a new unloader.
