Made tool to make another tool
First I made this chuck in a chuck that slides in and out on a steel rod, for drilling with small drills. Got the idea from Joe Pieczynski. I broke several drills trying to drill 2mm holes in stainless first.
And from that I made a new nozzle for the pressure washer. I'm still trying to figure out how the fan shape is affected by the nozzle geometry, I figured a bigger angle on the chamfer on the nozzle = wider fan. Though the chamfer on my homemade nozzle is quite wide it's not very wide, maybe 10 degrees. I was aiming for 30-40 degrees. Maybe depth also affect it. I am not sure how they achieve the flat fans, likely the nozzle is not round. I don't got any nozzles to look at to reverse engineer from.

I seem to remember 2 flat, thin stainless plates that moved progressively closer as the adjuster was turned that produced the flat fan.
This was on a very old Karcher I had donkeys years ago. No idea if this is a common approach or not, but it seemed to work ok

The nozzle tips are cut by lazer afaik (I used to work for Karcher) and I don't think its possible to machine cut them. The hole is actually slightly oval & tapered from the inside out.
You could try using a gas nozzle tip cleaner to file out your parallel hole.

We used to use them to resize nozzles on machines running over pressure.

Repair ends for the broken wooden spars on a patio brolly. I need to get some suitable screws now to replace the only one I could find in my parts bin.

You do know you're peculiar? Stay so.
Slightly odd, her says windswept and interesting.
