Thinking about acquiring one for the garage. Some paint spraying and
jobs like tyre inflating, fence spraying etc. Probably not major league
air-powered tools!

The Machine Mart catalogue has a bewildering selction to choose from. I
thought maybe the Airmaster Tiger 8/35: 7cfm, 10bar, 24ltr receiver,
1.5hp motor, £140.

Does that seem a reasonable choice for hobby/DIY use? If not, can
anyone suggest a list of specs or recommend one they use?

I looked on Ebay but most of the secondhand stuff looks like it's had a
hard life!

I got mine from ebay but it was a new one, cheaper than Machine mart.
The only thing I would say is get the one with the biggest tank you can.

Mine is 50 ltr and I wish I had got a 100ltr, I use air tools and I find the
drills and grinders soon drain the tank.

Don't under estimate the requirements for paint spraying, depending on the
type of gun this can be one of the most demanding loads for a compressor.
Also consider how cheap air tools are, £100 for a set of 6 on ebay for
example, at that price you may well regret buying a compressor that won't
power them!. Have you looked for second hand ones?, I got one at a machinery
auction for around £120, it's a twin cylinder 14cfm with 150l reservoir and
about the minimum you need to run air tools, Clarke sells them for £350 so
there are bargains to be had.

I upgraded to a 3hp 50litre as I found the 1.5hp 25 litre was not quite up
to handling impact drivers and other high demand tools plenty for light
sprayers inflaters and suchlike - I'm very happy with it if you have a Makro
card keep an eye open as they have them now and again at very good prices or
if you are near Chelford call in at the market on sundays and save a few
quid at the tool merchants by the poultry cages when I find his business
card I'll post up a link.

ive got a clarke rebel 30 (9cfm 2.5hp 24ltr apparently). I'm very
happy with it. Got it second hand off mr Davies when he bought himself
a posher one!.
I've never tried any air tools on it but it has so far sprayed the 101
and 2 cars and various bits and pieces and inflated a few tyres.

The only thing ive found about it is that 24litres is not quite enough
capacity to spray a complete car bonnet or roof without running out of
go. I still managed it but it took a bit of care to avoid a line where
i had to pause for air.

just adding that the day i manage to get a garage (it lives in my
utility room and i work outside) I shall be after a compressor of the
same or greater power rating but with a larger tank.
I used my dads old 1.5hp clarke one for half a car and in comparison
mine is much nicer.

Would you like me to point you in the direction of the loon that ran in the
side of the Rangie? Bless him! :)

now if you just wanted a larger tank to act as a slave I have a spare not
sure exactly what capacity but around 90 litre I was going to refurb the
motor but it got screwed up when a mong decided it wasn't worth refurbing
and kindly skipped it with the drive coupling attached it still has a pump
on (ingersoll rand ) safety vlave and starter cut out box but no motor and
drive coupling and since I bought the other one I don't really need it any
longer.

That's probably ok for pumping up tyres and blowing dust off things, but
when it comes to serious tools or spray painting you probably want a bit
more output and receiver capacity. I'd suggest looking for at least
12cfm and a 50 litre receiver for painting or extended use of tools such
as impact wrenches.

The other thing to be aware of is whether the output is being stated and
free air displacement (ie the swept volume of the compressor cylinders),
or a true output at a given pressure (normally either 40 or 90 psi).
You'll need at least 6cfm at 90psi to paint with.

As a general rule a belt driven compressor (ie the pump running much
slower than motor speed) is more reliable and longer lasting than a
direct driven compressor. It's also worth considering adding and extra
receiver to your compressor when painting to reduce the number of
stop/start cycles the compressor does - a general rule for fixed
workshop compressors is a maximum of 30 stop/starts a day (an old LPG
cylinder makes a good extra receiver).

You think you have space issues mate as well we have a bath in the garage
which is making it very difficult to get owt done I really must get time off
work so I can get it fitted apparently I'm too busy - like I hadn't noticed.
