Re: Media blaster troubleshooting

["MO ( Steve Mick)" <micher@xxxxxxxxxxxxxxx>]

A friend of mine bought one of those Harbor Freight cheaper cabinets.  He 
made the mistake of putting it together without sealing the seans--media all 
over the place. .
Steve , which modle do you have and are parts like gloves and carbide tips 
available for it? Doesn't the viewing window get pitted up soon?  I would 
like to have one myself.........................MO

Thanks Steve, I did not know there were carbide tips. Where do you get 
yours? I'm going to go back to zero with this cabinet and set it up again, 
all fresh, new gun tip, new media, etc., and will use the tips you all are 
providing on the forum to see what works best for me.



While the blaster did not work well with the gun that came with the cabinet, 
it did work great for awhile with the gun off my $50.00 outdoor Sears 
blaster that uses builders sand. I think now that the ceramic tip in that 
gun is shot.



One thing I'm thinking, because I only have been "trying" to use my cabinet 
once a month or so that moisture is probably an issue with mine. I'm going 
to get one of the water collectors like we use in boats and rvs around here 
in the winter and put one them in the cabinet, see if it collects any water 
and if that changes performance.



Because I'm running out of time to get this car ready for Hot August Nights 
in Reno, I took the wheels to a professional powder coating shop for media 
blasting yesterday. He said he never uses these types of cabinets that count 
on gravity feed, that even his small portables are such that the media is in 
a pressurized tank and the media is discharged under pressure, which he 
finds more reliable, I have not looked at any of those set ups.



Liked that...... "like a white shirt in a bar fight". :)

Butch,
We run our Harbor Freight blasting cabinet 8-10 hours a day 4-6 days
a month. As others have mentioned, moisture can be a problem. We've also
discovered that having too much abrasive in the hopper prevents the siphon
hose from pulling well especially with a coarse media.

You may also want to look into a carbide tip if you don't have one
already - aluminum oxide is great but ceramic nozzles last like a white
shirt in a bar fight...

I bought a Northern Tool Media blast cabinet some months ago. It is way
smarter than me and it hurts to say you've been outsmarted by sand and
compressed air!. I have a large snap-on 7 HP 175 PSI 80 gallon compressor so
think I should have enough air. I'm trying to use 70 grit aluminum oxide to
clean some wheels. The thing barely draws for awhile, then it will work like
magic for a couple of minutes, then back to nothing or next to nothing. I've
tried changing guns, running the media pickup tube in and out of the media.
Nothing seems to work for more than a couple of minutes. I have an air dryer
in line with the media cabinet.

If you've had some lessons learned with these things, please tell me what
you've found out through your use. This thing could easily end up in the
scrap yard, but I think it's probably something I'm just not understanding
about how to use it.

Thanks for any help. /Butch/ Ferndale, WA
