Hello everyone.
This time I'm looking at the container that holds the media when baking soda blasting with a Karcher.
Until now I'd been using a modified PVC pipe, but when the media ran low it stopped being drawn up properly.

Karcher Baking Soda Blasting Part 1: A Funnel-Shaped Soda Container
DIY soda blasting with a Karcher pressure washer, part 1: why the baking soda wouldn't feed, and building a funnel-shaped container from PVC pipe.
So I was wondering if there was some kind of funnel-shaped container, and I found something good!
A traffic cone. It cost less than 300 yen. But because it's cheap, the material is thin, and I don't expect it to last.
Let's drill a hole in the tip for the hose. First, a pilot hole with a drill.
Enlarge the hole with a reamer until the hose only just fits.
Once the hole is enlarged, degrease it with silicone remover.
Push the hose in.
After fitting the hose, seal around it with waterproof sealant so it can't suck in air.
Once the sealant has cured, I'll give it a try.
My Karcher blasting series
These are my notes from building a DIY baking soda (wet) blaster with a Karcher pressure washer. The set-up, tools and cautions that finally worked are summarised in my DIY guide.
- First try: baking soda blasting with a Karcher
- Part 1: a funnel-shaped baking soda container
- Part 2: a splash cabinet, and baking soda that won't feed
- Part 3: feeding the soda from below
- Part 4: clogs and air leaks
- Part 5 (final): what worked
- Baking soda blasting a carburettor
- Wet blasting with glass beads (fork axle holders)
- Wet blasting a rear brake caliper
- Removing blast media thoroughly afterwards
- Does baking soda blasting strip anodising?
- A traffic cone as the media container (this post)
