Towable pressure washer/30min water source

[jwmorris]

I decided I needed a way to flush rocks away from stumps I needed gone, had a gas powered pressure washer, old drum and a GM intercooler water pump.

The frame is 1.5 angle, notched and bent from 1/8. Same for the bearing mounts and battery holder.

Transfer screws make it easy to have “DRO” precision with simple tools.

Need to crack the lid a bit, once you start or it will suck the drum down. I’ll be adding a top vent, I detach it to get a full fill on the drum and reconnect it, why the axle is so far back. You can also see the shut off valve on the drum so I can take my washer back home.

I tapped the drum for 1/4 NPT and added a 3/8” sight tube, so I can see the level.

Turns out the 2.5GPM rating of my pressure washer was a bit optimistic or my water pump simply doesn’t produce enough pressure (it doesn’t really feel different from County supply) but 55 gallons lasts almost exactly 30 minutes, closer to 1.8 GPM.

It does what I wanted as far as blowing the gravel away.

I think once they are dry, some charcoal around the base might get these little ones below the surface.

I like it. Here's my trick for burning stumps. A metal sleeve 2 or 3 times taller than diameter. 2 metal 5 gallon buckets stacked with 1" holes around circumference 2" from ground. Metal barrels. Metal flashing rolled into a cylinder larger than stump and held with sheet metal screws of pop rivets. The chimney effect pulls increased airflow into fire resulting in faster consumption of stump plus some protection from embers and sparks blowing around.

Burning stumps is easy. I use a 1/2" auger it and drill several holes in the stump as far as I can, pour diesel fuel in the holes a couple of times, let it soak a few days and burn it.

Added a vent as well as a little more strength to the frame.
