Thought I'd share a project I've been working on,
As you all know,..especially the guys who do other things than roofs,..there is always a need for a small spot sprayer. A pump sprayer works very well to fill that void. Last season I put together a 12V hand truck rig as a gap filler for jobs that aren't big enough to warrant the air system. So the hand truck rig with 50' of hose on a reel works very well as a mid sized sprayer. But sucked for the times I need to blast the remnants a bees nest with some 12.5%,..or hit some rust "real quick" near an A/C unit or something. Or spray a few slabs of flagstone. So,.back to the pump sprayers for these small "shots"
So I wanted a small truly hand held 12V. So here is what I came up with. I first made one from wood and painted it,...I really liked the "prototype" so I had the local weld shop make me one out of aluminum. I made this so I have total access to the internals. Pump and battery and all connections are easily accessible. With this full 1 gallon jug of windshield fluid it weighs exactly 20 LBS.
But,..weight isn't an issue, only gonna be used sparingly as mentioned above. Could also add a shoulder strap if needed,..don't see me doing that though.
Can simply swap jug of this for a jug of that with no swishing out a sprayer,..and therefore don't have to have multiple sprayers,..one sprayer with different jugs and even a 16 OZ. water bottle maybe to rinse pump between chemicals.
Can also draw from a 5 gallon bucket if I choose,.and can also be used as a stationary unit with the addition of a longer hose that simply connects with QC.
The pump is a Seaflo 1.2 GPM,..and is a pump I'm trying out.,..and the battery is a small 12V 5AH. All connections are soldered and dielectric grease applied. I have a spare pumps on hand. These pumps will be abused by strong cleaners but I don't care,..they will make money.
The plug coming from the back is a charging jack,..I have the corresponding plug tied directly into my regular 12v car battery charger,..so,..I can simply "Plug it in"
Since these pictures,.I changed the routing of the outlet hose,..they both now come out the top front,..same as the suction hose,..more compact this way.
