Power Washer Sand Blasting Grit Comparison

[davelowe]

What I particularly like about the waterborne sand technique is that there's no airborne silica dust.

If you could fix attach the sand hopper to the washer, the vibration would ensure a more consistent flow of sand both from the slump cone and the movement around the inlet. Standing them on the same plank of wood may do it Bob.

love the comparison and that with a simple attachment you got a sand blaster. sorry if this is irrelevant, but there's probably a thumb print on the camera lens, it's just distracting me 😂

Robert Cut a hole in the bag (just big enough)and put the spike in it, save the mess of pouring it into the bucket and it’ll keep it dry . Love the review of which medium to use 👍

[MrGeoffHilton]

Great work, thanks for your videos much appreciated.

[MisterRorschach]

I’ve wanted someone to do this for so long!

Nothing gives a shine like blasting with crushed walnut shell

[karlmyers]

If I remember correctly I was going to try walnut shell to use on my alloy wheels . I think that's £20/30 for 25k

What I would really REALLY like to see, is you inventing a way to recirculate the sand in a cabin sandblaster while wet. :-)

[edwardcdg]

For a better solids silo, try a tall, rectangular (nit square) cross-section box with a 60 degree (minimum) pyramid bottom. This discourages 'rat-holing' and bridging. From industrial experience.

In addition to this attachment, if you were to create a trough for putting parts into with a pipe going back to a water return, and on its way, run it through a cyclonic water filter, you could return the medium back to a separate tank from the water for re-use. Therefore saving your medium. When the water hits the cyclonic filter, the medium would go down the way and the water would go straight through.

Good video! Only issue is they use a LOT of water if you're on a water meter! Not sure how much or what cost aspect that would play as quite considerable I'd imagine but I can't be sure?

great video rob cheers for that test .... use full to know paving sand is good for this application

[barbufodor]

this is very informative. How about time efficiency?

[duluth]

Have you looked into a web blast cabinet? you convert a typical sandblast cabinet to wet. That way best of both worlds and it recycles the sand I believe. Worth a look mate!!

In the States, there was a company marketing something similar that used sodium bicarbonate for grit. There was a need to decontaminate the surfaces before re-treating, but the cost was said to be very low. Enjoyed your comparison. Your indoor lab shot camera lens is slightly fogged over the last several videos -- FYI. Seems to be getting worse.

[HeimoVN]

The black grit can be carborundum like you said, but it can also be crushed up slag from iron smelting, I seem to recall reading somewhere that they use crushed slag for media blasting...

[maxkennedy]

Was there a difference in the grit sizes to explain the rate of use or was the expensive stuff significantly heavier per unit volume?

[hippie-io]

I bought some aluminum oxide that looked just like that. I found the oxide quite useful to make home made ceramics, binding it with sodium silicate.

Pro Tip - please clean the camera lens - there has been something blurring the last 3 videos. :-) Hopefully these are not filmed too far in advance. Love your content - keep it up.
