I have had about 3 blasters like this. My first one was purchased in about 1979, long before Harbor Freight, but it was the same design. I used it to blast porcelain and rust on washers and dryers so that I could repaint a machine. My Uncle also had one to blast airplane parts with walnut shells. It worked great for him also. One thing I did to help remove water from the air was to use a condenser coil from an old refrigerator to cool the air just after it left the tank. I then connected the regulator and water trap on the output of the coil. It helped a lot.
That's cool Gary! Yeah, I've been kicking for years around adding a coil on my 60gal shop compressor, and still am. I've installed an auto drain on it that does keep the tank dry, but I don't drive it as hard as a blaster would. That's probably where I would use this in the future instead of offsite like I did here. Thanks and take care, G.
Wow what a treat 2 videos in one day from Gman. I can tell a huge difference in the stone it looks amazing after you media blast it. I don't think i would of sealed it to begin with in that application. Good to hear the little blaster from Harbor Freight is working out well for you it looks like its making quick work of the job your doing. Keep up the great work and videos.
Yeah, I wouldn't have done it. It guess is was the thing to do at that time. Didn't stand the test of time though. I was quite surprised how well it worked- no mods- no nothing. G.
Thanks! Please do- my channel is filled with reviews, how-to's, and general information on various topic. Check out anything of interest to you and ignore the rest. Take care, G.
Thanks Loyd! That's exactly why I went this direction. A chemical remover would've been a huge mess for sure. I did have a mess to cleanup but it wasn't that bad- all things considered. Take care, G>
Nicely done G! Appreciate the review and the tip on carbon from TS. Did you consider walnut shells or would the gun handle them? Always messy bidness to sandblast in the open. A 100 years ago I did the internal hull under the deck plates of a 40' steel hull boat...even with a full hood, jacket and pants I secreted black/brown crud for months...hate to think about carbon!! Looks good and surprised you covered that much ground so shortly! You never did tell the SCFM for the gun...at least I didn't hear it. Thanks Man, Great to see your work and hear your voice again! ~PJ
Thanks PJ! I actually have walnut shells for my blasting cabinet. They don't feed well and didn't try them on this project/new rig. I'd seen another review that touted the slag and how well it fed so I went that direction. I did state the specs in the video but don't recall what they were. G.
The air passing through the gun creates a suction that introduces/sucks the media into the air stream. A venturi effect- so to speak. Hope this helps, G.
I'm not gonna lie, I burst out laughing with that black lung bit. Really beautiful improvement on the fireplace. When I'm running my compressor at nearly-continuous duty (for a CNC plasma), I like to point a blower fan at it, just because I imagine all heat won't do it any good long term. I did a video on it months ago, but the long and short of it is, without any cooling, my compressor leveled out somewhere over 300F (can't know exactly because the sensor maxed out). With a HFT #97762 I could keep it around 260F, and with a *big* 1kW blower motor, it was staying about 210F. Is 210F the right temperature for a compressor? I dunno, but it's in the normal range of a car, and it sounds way better than 300+, especially with how frequently I'm operating that plasma.
LOL! Thanks! Good info! The compressor was running hot for this no doubt. I thought about using a fan but had to use the one I had to exhaust the "smoke" from the slag. This was more of a on-time-gig but will do something else if need be. Take care, G.
I did Jimmy, but I can't say what the runtime was as it's really dependent on the time spent on the trigger. No help, but hope this helps. Take care, G.
The harbour freight is a hopper container not a compressor. CONTAINER THAT HOLDS SAND OR BAKING SODA. ect I thought & bought 1 dam cost me $100:00 new Zealand. Never the less. Its a stayer. 🤗👍😭🤣😂

I love all of your videos. I wish all youtubers could be like you.
Thanks Hugo! Glad you like the videos. Take care, G.

Awesome vid... Very Good!
Thanks! Take care, G.
Nice video. Thanks for sharing. Will be checking out the rest of your channel!

You said to not cover up the bleed hole on the supply connector... so how does media get into the tube?

Do you think this would work to remove paint from an exposed foundation or would it be too small for that type of project?
I would say too small Saul. G.
can you reuse the media and if so, what do you strain it with? Good review by the way. Project definitely looks much better. Take care
Yes you can Brian. I used window screen to strain it. Good luck, G.
@@ghostses Good thinkin. Thanks
No problem! G.
The first thing I did was cut hose and fix the trigger.
It sound's like the kink in the hose is common. I didn't have any problems with the trigger on mine. Glad you got yours going. Take care, G.
I think you said you put about 25 lbs of media in it? Any ifea on the runtime you got out of 25 lbs?
I did Jimmy, but I can't say what the runtime was as it's really dependent on the time spent on the trigger. No help, but hope this helps. Take care, G.
is that a mid 20th century house?
1973 Dave! Good to hear from you, G.

No it's not. You should've known that just from looking at a picture. Good luck, G.
