DIY wet blasting steel 

Johns suggestion on diluting the mix sounds like a winner!

Glad to know wet blasting works with a portable pressure washer. Now I know how I'm going to blast my boat trailer. Thanks great video.

Must compliment your editing. Cutting the minutia, and narrating even the simplest task, teflon tape, is super helpful. Keep them short and sweet. The one thing that kills me when watching a vid is long winded super long vids , YOU get to the point and are real about it. Thanks.

A fixture adapted to a fixture. Pure Genius and I’m not kidding. The inadequacy of my ability to do anything meaningful is self evident. I’m not even a boater, but I’m fascinated how you pull everything together and the very through step by step instructions.😀

I didn't know there was a wet blasting kit for pressure washers. Excellent! Thanks, I'm going to check it out.

Another brilliant instalment Stu. I think problem solving is such a satisfying pastime, particularly when you can see the fruits of your labour. I'm waiting, almost patiently, these days for the next episode...........

Scrap packing crates make a good diy blasting cabinet. We made one from a big engine crate and when dry blasting we could recycle the media. Was madeonly for the time it took to get the bits from the dump! Everything came for free from the dump! Lights,household extractor fans,windows etc. It was big enough to get a motorbike frame in and doing side jobs it earned a bit of money- got to love that! Doing the side jobs covered my fuel costs so other than labour I got my blasting done for nothing! And we do like that cost!

The green machine is definitely getting jealous with all this love you are giving to the trawler

Hard to say what's more fun.Starting a new project or playing with all the new tools/toys it takes to finish the project! Nice addition to the line up Stu!!

That wet blasting is fascinating - I learned something else today thanks to your project Stu. Gotta say as well I am very impressed with how much consideration you are giving to the impact of your work on the neighbours, environment, etc and make choices accordingly. Having lived through the noise and mess of having a neighbour take three years to build a house part time - those impacted I'm sure appreciate the good manners of a guy like you!

Good tips on wet blasting! Can’t Waite to start blasting the hull. Love the glove chair!!! Nostalgic!

Looking forward to you solving and starting this sandblasting process Stu .

I really dig this series man . Can't wait to see it all done.

I use a small blast cabinet for the bits and hire a blast pot for big items but never thought of wet blasting, great idea Stu

Watched all your videos ( whatever you call them these days) ....love your passion and the informative nature of the videos......love the wet sand blaster.....keep em coming. I really look forward to the next episode.😁🇦🇺👍🏻

Exactly. I assumed by the time I got to the comments someone would have already presented the obvious solution, which is dilute. Clearly adding water to the chemical isn't an issue so this is pretty straightforward.

Mate, I never clicked so fast on a video. I really am enjoying this series. Thank you from Pennsylvania USofA!

Glad you tried both methods, I've been interested in trying wet blasting, and nice to know that the kit works straight away.

G’day Stu thanks for the differences between the two sand blasting techniques and explaining how to use them, very interesting thanks again John

Hi Stu. I’m really enjoying this series and your channel. Regarding the Chor-ID, I agree to dilute it to achieve the correct amount is used. I’ve seen this on a lot of American house washing You-Tube videos where they need to dilute the bleach to achieve the correct application percentage. Keep up the great work. Cheers. Jeff

Wow your diy wet blaster works great! Thanks for the video.

Absolutely loving this thread

Keep it up. Doing a cracking good job. Watched all your vids in one sitting. I love your get it done attitude. Your willingness to drop cash on the tools when necessary. Musta been fricking hot in the engine space. I’ve done dry docks of ships as a deck officer in merchant navy and know it’s a bugger in tanks in the heat., an Aussie summer!! Your an marine athlete.

Very helpful. Thanks for answering several questions I had.

Excellent DIY video. Thank you very much for explaining that very well

I've sand blasted for some time but this is less hassle. My sand blast is like a cone I could put up so it could be both aspirated and through depression get to the pressure washer gun. Will definitely try that. Great job and explanation

Trial and Error- you do a great service! I love it, and keep following.

I drove past the other day and could hear blasting. I got excited.

Works pretty good. When I did my boat trailer I put a big tarp on the ground to let it dry for a day or two so I could reclaim the medium.

Watching that wet blasting I was thinking holy cow he isn't really going to do the entire hull like this is he. That would take a literal year to complete.

This is my exact setup - including the sandblaster ! Make sure your abrasive media is absolutely dry - or it will clog up inside the sandblaster hopper.

Thanks for posting your experiment! I am trying the same thing for blasting a pool. Same sandblasting gun at 4200psi and four gals/min. I occasionally had a blockage in the feed line, so I replaced it with lower friction, longer irrigation tubing. Also found that joints or valves create a place for coarse silica sand to build up. I built a sealed container and fed air from an HPLV paint sprayer unit directly into the air feed pipe on the sandblaster pickup. The idea is that with a sealed drum, pressure will increase inside, while the airflow next to the sand pickup will slightly stir the sand, and most importantly, hold positive pressure in the long feed tubing. That part works very well, in that previously, I was getting moisture feeding back up the tubing and creating a clog. The latest test I did is with dried and screen-filtered recycled sand. Unfortunately, the sand is pretty beat up and has concrete dust mixed in, so the flow was not optimal, and the particles were too small and not sharp. Pros: the sealed container keeps the sand dry and keeps back-fed water out of the line, also on wheels, so it's easy to move around. I assume the air flowing out directly beside the steel pickup tube is helping because, with the washer gun off, there is still a powdery mist of particles shooting out of the blaster nozzle. Cons: I haven't found any yet, but I expect that the air may be less effective in stirring sand grains or too effective and reduce flow density with new silica sand. I will soon find out. Thanks again for posting your video!

quick silly tip . When you're applying PTFE tape flip the roll over . That way you can control the tension as it unwinds from the spool onto the fitting. The way you did it is as it unwinds from tape spool which has a bigger dia than the fitting and there fore is always slack. Try it you'll see what i mean . Really enjoying the steel boat series Cheers

That video was a blast !! 🇬🇧

Good work Stu.

Hey mate. Just wanted to say thanks for going to the effort of making this video.

Love the hand chair bro

That came out really good Stu. We started with the exact same set up with our blaster on Brupeg. We found the higher the air pressure the less garnet you use per sq meter as the force of air allows high abrasive action than just firing sand at the steel. We also us the same pressure pot as you and have found they do block up easy if any rubbish gets in and once you are down to about 29% left thin the pot it doesn’t flow through.

Great videos, I just found your channel and started from when you got the boat. Cant wait for the next video, keep up the great work.

I have a wet blast kit. Worked good. No dust. Had to keep sand vibrated to maintain flow.

As usual Stu, a very detailed and useful video which was easy to watch. I sometimes feel that you try to set us up for replies (thread tape application for example) but that is also cool mate as then you are certain to stress a good point. Thanks for this video.

Put the medium into a bucket, and put an orbital sander, in a sealed bag, in the bucket, plug it in, it will vibrate and help feed the sand. Also a thought, once I knew a guy that had a contract to pressure wash a cedar shake roof, there was no water close by and he was to wash it with a preservative mixed in. He set up two 45 gallon drums on their side with spigots teed into the pressure washer, in his truck bed and backed up to the building, you might be able to do that in order to get the right mix of chemical.

Thanks Dangar Stu.....Learned so much from this video......this channel is great....keep it up matey

Nice demonstration. Worked well. Thanks

Look here young fella - 'dingo'. I'm a fat, old, ugly and English so please perhaps the occasional 'Pom'. We had a shot blaster at work, it was a complete room lined with 6mm IT100 armour plate. It had holes blasted in it over the years. You are very professional, not only in your work but in your video presentations. A real pleasure to watch. Thanks.

Thanks for doing this test. I was learning a lot. Awesome !

Had no idea that you could get a wet blast attachment for a power washer. It looks like it works good and will be kinder to your hands then the needle scaler. Glad to see the project progression Stu!

I have a less powerful Kaercher pressure washer that can draw water from a tank or fresh water pond rather than using the mains supply. I collect rain water in plastic barrels and drop the draw tube in, works great. You could pre mix the chemicals (Chlor rid) in the tank to the correct ratio too.

This guy is a legend I wouldn't have the patience with all these little bibs and bobs to deal with. DIY is the self Imposed standard there I think but mate how much time is going under the bridge at the same time. I did sandblasting myself and I know these days environmental protection standards are a big pain in the groin.

I am enjoying watching your video! I am not a handy guy to have around as I am 81! But do enjoy learning new things! 😊

Beat video on diy sandblasting. Cheers 🍻

Another great vid....his expertise is endless.

Excellent video!

Awesome video, I have the same pressure sand blaster, and I never thought to use a water blasting set up, I will definitely try the water blasting on my next project, it seems much easier and way more safe for my lungs without all that dust 👍🏼

For the type of work your doing, I've used simple "Play sand" that costs next to NOTHING at any hardware store. Works great!

Another great video with very useful information

Thanks for documenting your journey. It's really great to watch your success but also grounding to hear your struggles.

Awesome little kit, I had no idea you could buy it.

Just dilute the chlorine 5:1. As I wrote this you said that. 😂 Edit - loving this series by the way. I don't own or intend on owning a steel boat any time soon but really enjoy watching people restore old vehicles. Thanks for taking the time to film and share it with us.

Excellent series...

Love your vids mate, champion.

Have a look into crushed glass its very sharp and cheap to buy if ur not reusing to many times as it degrades quicker than garnet but for ur purpose probably perfect and quick also make sure u ground ur blaster and what ur blasting cause u will get static shocks just a matter of when

Move the Esky for icy cold beverages to within arm's reach of that very stylish chair.

Great demo

Just a tip if you're stuck between pipe sizes, say for the likes of your Nitto Fitting the way out is to buy a threaded 'Reducing' Bush from the Ball valve down to the old Nitto fitting, then you're good to go... they can be bought for small change... saves a few Bucks ..

Keep it simple. The right move. Thanks.

man you got me hooked this is interesting and I was like its going to take him forever to do the whole boat then u said u was bringing in a pro lol

Working well there.. nice.

suggestion for the Teflon tape, you need to put the up side of the tape on the thread so that you can tighten the tape with the spool when putting it on the thread, if you get my drift. ...cool project Stu .thanks mate.

The chair you were sitting in is fab.

That was a surprisingly simple blasting setup for small scale work. Interesting. BTW I think you should tidy the lounge before you have visitors over. Working on boats is a messy job but you've got maintain standards!

Great video! 👍🏻

Cool chair.

Can you add a long video of you blasting the whole hull please, it’s too long between videos stu. Can’t wait 😊

Opened Up another Can! Well Your Weekend looks Booked Out? Beauty DM, lovin this Restore.

Nice set up mate...the door is looking schmick too and will be a great addition. Cheers :)

I really like watching your videos! It brings me back to the days I worked in local boatyards. I noticed that when you take uts and bolts apart you don't crack it tighter first! The idea I was taught is that compresses the junk in the threads. Usually the idea is to just "crack" it; move it the slightest amount, then re,move the nut/bolt Worked for me in the salty Northeast Atlantic! I would appreciate your ides/opinion on this!!!

I have seen the guys that do the steel trawlers over here have like a giant funnel on a stand that they can tip a few sacks of grit into that then just feeds from the bottom into the gun/nozzle they keep the stand in the van so it stays dry and it saves unloading it

@dangar try using welding tips in the line for the soap line. You can try different sizes and if they are too small you can drill them out to tune it.

Thanks for the video.

Enjoy your trawler videos!

Not sure if anyone has suggested but here goes. Use a ubc tank or poly 55gal drum as your water source. Power washers don’t use much water and you can get your chlorid mix just right. I’ve tapped a spigot to the bottom of a ubc tank (what they use to ship liquids around) and keep in the back of a trailer so gravity forces water into the pump intake. With the gas power washer and this setup you’re good to go anywhere and use it. Good luck and thanks for the vids! Always look forward to the next one.

The washer will only suck the detergent in with the low pressure tip on the sprayer. You may have to get a large tank or barrel and gravity feed water to the washer. you can then mix your solution in large quantity.

I agree on cutting the pressure pot out. I sold mind because it was to fiddly. often getting clogged. I had a good feeling on how much to open the valves towards the end to get it running consistent but still found it would clog every so often if you were idle for to long. id like to try the wet blasting seems all around better.

I'm impressed!

Was going to suggest simply diluting the chlorine beforehand but mentioned in the video that you'd already gotten that suggestion. Keep it simple!

That's cool Stu, never have seen wet sand blasting before. Looks like it works good. So you plan on having the exterior hull done. It will be faster for sure plus the activity probably be cut down to 1 day for the neighbors😁. Its finally warming up here going into spring. Finally got back to my tilt trim project reinstalling on the boat. I'll have the new video out soon. Also will make one on the lake run before the end of the month😁

Love the chair

That seemed to work so well, I'm wondering if you need to do so much with the needle gun? You should try that on some areas that aren't under the water and you could probably get by without needling the entire hull!

I rigged up a simple gravity feed and it worked good. Was only my media in a hopper on top of my steps,about nine feet up. If it blocked then a tap on the steps sorted things out. Simple but worked !

I have that same blaster pot. I found it quickly gets "cloggy" and I get better results if I keep shaking the blast pot to keep the media flowing. So you may give that a try when pumping the 40psi of air through.

Did I imagine a cinematic villainous smile while you were holding that BFG device? :) awesome vid as usual.

Nice video and chair 👍

You've put together a close clone of my original system. I no longer use the 10 gallon sandblaster but use a large plastic garbage bin in which I have installed 12mm T piece with a series of 3mm holes drilled on the underside of the T crosspiece, which has.its ends capped. The compressor is hooked up to the stem of the T. I then use the supplied induction system, including the twin tube feeder, The T piece is zip tied to 3 reo-steel supports and the feeder tube also zip tied so that it is picking up medium under the T bar. I now use sieved sand because; a) I can get it for free, b)with wet blasting you do not have the same health issues as dry blasting, and c) if you are not recovering your media garnet can get very expensive when doing large surface areas. Since the biggest job I have ever done is the rear of a 3 metre grader blade I can get away running a smaller compressor at about 30/35 psi. My set-up is far from original and was shown to me by Canadian Dan about 40 years ago, though feeding a dry blaster. A 120 litre bin will give you enough time to want a smoko by the time it needs refilling. Thanks for taking the time to put your efforts on You Tube, your work makes my leisure quite pleasurable.

Hey man, make sure the sandblaster is dry. The moisture from the compressor fucks everything over. Run multiple water traps inline. Worked for me.

John is on the money... just put 1L of Chlorid in a 100L barrel (they always fit a bit more volume) and top off with water, good to go 👍

You need one of those oscillating pressure washer nozzles. Will be a life saver when you're trying to use this to blast large areas to clean off paint.

glad to see another video, just wish you would do more than 1 a week, or show more content. Good luck and hope you get it done soon

Nice one buddy👍🏻

Thank you, excellent education !
