Simple pressure washer tips, or oil pressure restrictor

[jere]

I bought a "broken" gas pressure washer a couple of weeks ago for $20. the last owner clogged up a Schrader valve with some dirty well water. the washer never worked right for him and he just wanted the space back in his garage. I cleaned up the parts inside the water pump, put in some new "o" rings and swapped the mystery oil gear oil for some redline transmission gear oil. the pressure washer worked like new after this but the sprayer was missing its high pressure tips. I decided to make a few of my own.

I don't have any micro drill bits around so I improvised. I clipped of a few section of picture frame hanging wire for my drill bits.

next I used some fittings that fit the tip of the spray wand. these could have been any cheap open ended brass or steel fittings from the hardware store (mine were from the pressure washer section but similar were in the plumbing section). I drilled out the fitting's internal diameter to remove the zinc coating, so solder would stick.

I wrapped up one side of the fitting with tin foil. inside the fitting I clipped short lengths of solder, and melted them with a torch. last I drilled through the center of the cooled solder in the fitting, with the wire ends clipped flat across. drilling was a little tedious as I used an egg beaters hand drill.( alternatively I have coated the wire and centered it in the fitting while the solder was still hot. )

I have done this before to make an oil restrictor for an automotive turbo charger too. while no one probably needs to make a fitting for a pressure washer, maybe this could apply to so other custom restrictor for another builder.

sorry if this is the wrong place but wasn't sure where to put this
