I have been looking for an air compressor for a while

so this week end i go on Gumtree (Aussie craigslist) and se a few deals
the best being a long way away
the full story is in the "Have u ever" thread but basically i drove a 3hr round trip to achieve nothing

that was Saturday morning gone

later that day i went and looked at two small 25 litre compressors
$50 ea
thought that wasn't too bad
show up and one is missing a load of bits and wouldn't even try to turn over
the other, clearly sounds seized
i told him id take both for $30

i pulled the head off the seized one and put 1/2 a litre of waste oil on the piston and left it

the one with missing bits i try to fire uo but on inspecting the pressure switch shes toast wired a lamp switch into it and the motor/compressor are good
go back to the seized one and put a 24 inch shifter on the motor shaft
well its not seized any more runs great now after an oil change

they make good compressors but have F/A output
so ill flog them off
should get $100 for the good one
and illpart the junk one out
someone wants the air tank for their 4X4 they are giving me $20
someone else has a burnt out motor and wnat my motor for $15
so that turned out good

Then to top in off i find a good deal on a medium sized compressor McMillan mc12 with an mc15 pump
I believe its 15cfm witha 58t tank
this one also works well
It keep up with my air tools like the spray gun and sander
It had an old air fitting in the pump breather so its going to get a DIYGK patented fuel filter breather
The pressure gauge was in kpa which means nothing to me
but luckily one of the 25lt ones had a new psi gauge
It still needs a regulator and water trap
cost me $150

if i ditch these 25lt ones quick i think i can call this whole game a win

EDIT
yes it is chained to a pole
no it wont stop any self respecting thief from using my grinder
but hopefully they'll grab other junk first

Nice score on the McMillan, they have a pretty good reputation, it shouold handle anything you throw at it; a larger tank would be good but, whacha gunna do...

Over the years I've found those little direct drive units are ok for light duties, they'll handle a spray gun or tyre inflator but, that's about it, don't even try connecting a rattle gun or air chisel; my old 2.5hp 40L would only run my air hacksaw for about 5 minutes before I had to stop & let the compressor catch up...

All in all, I'd call it a win... :thumbsup:

I am going to get a decommissioned fire suppression cylinder from work
They are 100 lt and stand upright
Rates to 3000 psi an out of date one will hole 100psu just fine
They are all stainless so no rust

dam it
motor burnt out

now its a $350 compressor

:confused::confused: I'm sorry, but I have to ask...

1] What just happened?

2] Did the motor pass the color and smell tests for the insulation for the windings, before you tried to use it in anger?

If it's a small motor for residential/ consumer use, this is where I would start to ask questions.....

I used it for a few hours and while it don't sound flash it worked fine

Turned it on last Tuesday night and all I got was 3 revolutions
Then a big arc out the back
Then the breaker tripped

I took it to APS rewinds which is an AC motor joint that We've been using for years for our pumps

They said it was U/S
So I went and purchased a new motor

The old one was 15A 1600watt

The new one is 10A 2200watt
It cost $200

I'm sorry,but I have to ask; when you say the old motor was U/S, what does that mean? You purchased a new motor, which means the old one was scrap. The question I have is what/when/why?

Or am I just growing old?

Unservicable?

If I had an electric motor that shot a big arc out the back, I don't think I'd bother trying to fix it either; my guess would be something's either shorted (in a big way) &/or welded...
