Since 2002 i have glazed every single pot i made with the harbor
freight "hvlp" gravity feed spray gun #43430 (with the purple handle) and
the 2.2 mm tip (which is no longer available) but i have had to return
them many, many times because the same thing eventually happens to all of
them: they start to leak right near the trigger where the needle slides in
and out. The part that holds the seal there, called the "packing nut" or
something, is not replaceable so once it wears out the gun is a real mess
to use. So for a long time i just kept walking into the store, asking the
latest newbie on the job if i could swap this one out and they almost
always just say yes, go take another one - but it gets old after a while
so i finally started looking around for something better and i bought this:

20DEVFLG651G22.htm
Just for sentimental purposes i bought another HF #43430 since they were
on sale on line for $20 and i printed the page and brought it to the
store, plus i also exchanged my old one again so i will keep using these
from time to time.
But the devilbiss ones seems much better, at least that is my first
impression after using it today for the first time, and the packing nuts
are replaceable so it is not a throw away gun.
so i guess this is kind of a review of an alternative to the cheap spray
guns as well as to the high end ones (which are made for spraying
$400/gallon automotive paint, not glaze) and this one seems to be just
right for someone doing a lot of spraying. It has a bigger cup to. It
works much better with an air pressure regulator than with the needle-
valve type regulator i bought along with it but will return (the middle
one of the three shown just below the gun on the link i posted).
Is anyone else using this sprayer? If so i would like to know how well it
has held up over time.
thanks,
Paul

Hi Paul,
Nice looking Gun..!
That is a good Brand of course too.
I just wanted to mention...you can run a few feet of light flexable Hose to
the inlet on the Gun's top...and have that Hose come from a gravity feed
Hopper mounted on a hook or whatever...so the weight of the Gun is instantly
a lot less, and also so you can turn it more and so on in use, without
dangers of spilling.
Or you can have a simple pressure feed Hopper on the floor or a close by
table, and a longer Hose.
Devilbiss and others used to make pressure feed self stirring Hoppers or
Reseviors, which used the incoming Air thence going to the Gun, to run a
little Air Motor which turned the stirrers...but the only ones I ever saw
were very old so I do not kno if they still make them. You'd think they
would...
Ideally one would want to slosh or stirr the Contents of the Hopper of
course, so things do not settle or seperate...
When I was spraying Glazes, I did not have a great many to do and i did not
have Spray Gun of any sort, so I just used a smaller 1930s Hand Pump 'Bug'
Sprayer that I did have...and it worked really well but of course had a
modest volume-output. Truely though, those were a definite LVLP ( Low
Volume, Low Pressure ) in their own way...but could be used very delicately
also, like an Air Brush.
If I were to be spraying Glazes again, or spraying anything where there was
much of it to do, something like what you have there would be really
excellent...but I would have a Hose coming from distal Hopper/Resivior,
instead of the Hopper being mounted on the Gun.

After glazing 75 or so pots with this sprayer - all pots glazed entirely
by spraying except inside of mugs, vases, etc - i can say for sure this is
a great sprayer and i wish i had bought this 5 years ago instead of the HF
43430. The devilbiss has a larger spray pattern that covers pots even
faster, especially with the 2.2 mm tip and, on whole, it just sprays
nicer. Totally worth the money, and since all the parts are replaceable,
it will most likely last a long time.
i have thought about doing what Phil mentioned, using a larger reservour
mounted above the booth or wherever, for the glaze instead of the cup on
the sprayer - but for my purposes i would need several of them and the
extra time and expense would not be needed. Those pressurized paint cans
are not so cheap plus all the hoses, fittings, etc all add up. I always
use both hands on the sprayer to help minimize wrist strain and it also
helps for holding it at all different angles, using the trigger hand as a
kind of pivot point.
Very nice sprayer.

Hi Paul,
Certainly several Gravity Feed Hoppers/Reservoirs could be arranged, made
from anything really, whose slender Hoses could have a simple Petcock at
their end fitting, for turning the flow 'off' when wishing to switch to the
next one.
Probably, an alternative to a Self-Stirring Reservoir would be one which
merely gets Air bubbleing through it from the bottom...intermittently, or as
may be, as for preventing
ingredients from settleing out and spoiling the ratios of the mix.
The problem as I imagine it, for Glazes in a conventional pressurized
Reservoir, would be their tendency to settle unless agitated.
And an arrangement of Gravity-Feed ones holding the Glazes to be sprayed,
they could easily be swirled or shaken even, by hand, by merely reaching
'up', and they would not be
difficult or costly to make.
Best wishes...
Phil
