Decommissioned LP tanks are ideal to convert for this purpose because they were designed with a safety margin well above the 200psi possible LP pressure and this application is only 110psi. It's now on half duty for the rest of it's life which could be a considerably long time at that margin. You have shown how to safely modify them. Good job. You gave it a fun paint job, so extra credit there. Mine is a "Ketchup" bottle made from a 20lb tank about the size of the one you replaced.
Dam and Jess with Brupeg kept me sane while my wife was going thru Chemo its a long road and it sucks hope you are recovering well kind regards kiwi Chris
Hi, Kelly! I can't claim to understand what you're going through, but I've heard that it can be rough. I spent 16 years providing 24-hour nursing care at home for my late parents (without help, respite, a break, or more than 20 minutes of uninterrupted sleep at a time). I was dealing with Alzheimer's [dementia], cancer, and various heart, lung, and mobility problems. I think sixteen years of feeding, caring, lifting, carrying, washing, and dodging the occasional fist and flying chair drove me slightly nuts, but one thing I DID learn is that maintaining a positive mental attitude counts for a lot. Having a sense of humour helps; I'd say that you're doing exactly the right thing in following Jess and Dame on Project Brupeg. Their attitude is just bursting with positivity and good humour, and I'm reasonably sure that a laugh and a smile never did anyone any harm. So good luck - and try to keep smiling. 🙂 I wish you well!
@@EleanorPeterson thank you very much . I am unaffected of any of the possible outcomes this my bring . What I do fear is leave my 9 yo daughter with out her father or her deadbeat mother . I do not say that out of anger. She has chosen not to be apart of her daughters life. .
I don't know where you are.. re legalisation.. Look into using CBD etc ... obviously ask clinic they may give advice ... It can help reduce side effects...
John Britten just took time out from his bike building in heaven to view this video……he put his feet up on an old oily drum, screwed the cap off a cold one, wiped it with his dirty, ripped old tee shirt, took a swig and then whispered to himself “By crickey, you just can’t beat kiwi ingenuity”. Well done, a very well explained video and the artwork was the awesome.
Thanks mate, took a few versions of trial and error to make it work but we got nearly 4 years out of rolling thunder before the cheap ebay cement mixer died on us.
I have the same sandblaster, only use it occasionally so it's not modified. I strapped a vibration motor to it with a foot pedal, as I found the garnet/glass I use (and was re-using) didn't flow down and just created a void. Shaking it kept it running great. I fed it from an old diesel powered road compressor, so had loads of air.
Thank you so much for that video. I have often wondered how you dried your sand. Now I have a DIY build video for a wet blaster which I heve some work for. All the best for your future adventures, I wish I had the resources to help you but that is not the case. PS I am also a big fan of Dangar Stu. I anxiously await his return in any format.
Wow, you two are the most industrious couple I’ve ever seen...but that minion...shoot, that’s so cool and funny and USEFUL most of all!! Thanks so much for the tutorial, it was great!
Been loving you for a few years, but this was an exceptional episode, the Minion reveal the icing on the cake! I don’t envy you the task of blasting the hull, but at least you are well prepared!
Amazing job mate, first video of yours I’ve seen. I’m a Jack of all trades myself and build/fix everything as I can’t stand paying big dollars for something that I can make or fix and with trial and errors I can make it better than the new corners cut to save profit products you can buy on the market. I needed so information on turning a diesel with big hopper into a dustless machine and this was a great informative and helpful even to someone with years of backyard hacking experience. I’ve subscribed and watching all your videos and look forward to future projects you do. Ps I need a plasma cutter. So much better then my oxy. Cheers mate Paul Martin
Your ingenuity and practical problem solving is such an inspiration. I use a shop bought spray gun to do small projects and it is just the job and I got the idea after watching how your sand blasting setup so thanks for the inspiration. Love the channel. stay safe J.
Well put together and presented, must have taken a while to do. Although the sand may be “silica free” I understand that this only has the fine silica dust removed, sand particles are silica and when they break down will produce fine silica particles. Your wet blasting is a great way to minimise problems
O man you cracked me up! when you tried to turn the cylinder upside down, while lifting it between your legs. Thanks for the laugh bruh I needed that. BTW Damien you did a great job on that sandblaster rebuild. Now you just need to figure out an efficient means of getting that sand transported from your storage bin into the sandblaster. Good luck with that, hope you figure it out without needing having to hand bomb the sand into the blaster yourself. Maybe use your winch to lift it up the sand to a higher grade then gravity feed it into your blaster. cheers have a good week guys.
@@ProjectBrupeg I wish I was able to come to Australia and help you guys. Of course I have no idea what I could help you guys with but would love to learn. Best wishes from American and if I see you guys are coming to America I will definitely make sure I come see you guys.
Really good video. Lots of creativity and thinking ahead. Only thing missing is media recovery. I assume after you blast an interior you still have sand to clean up. I know it depends upon how much you pay for media, however since you have to sweep/vacuum it up anyways it would seem like it should be cost effective to run that used mixed paint/media back through the screener. I would consider some sort of set-up wherein you only move it once. From the truck bed into a hopper of sorts, run an Archimedes-type screw to move the media into a screening section, which deposits screened sand onto a conveyor which fills a small silo. You blokes seem pretty creative, and this would cost only a moderate amount with your welding skills, and potentially free up some man-hours wherein it could be working while you're blasting. I know it always sounds easier than reality, but I think you could make it happen. Also, seems like you could dry your sand in 55g drums over a fire/heat vs having to dump it, wait, then shovel it back.
Cool upgrades! You can use a Chicago coupling to mount your ball valve. They're available in a variety of sizes ample for abrasive flow and they use easily replaceable rubber gaskets. The more simple quick disconnects like Chicago couplings and air brake glad hand fittings (you may like the profile) in your system the quicker you can service it.
Although I enjoy all of the episodes this one was definitely the most detailed and informative one. I’m wishing you folks the best of luck in completing your dreams.
You could use a rig to lift the ICU bin above the blaster, that way you can gravity feed the sand down the funnel. It would need to be very strong one of the bins with all the blast material is going to be heavy.
Bro. Im a little late to the party but that was a bad arse vid on makin great working equipment from the shit thrown out. I’m a hobby machinist in Syd & luv repurposing materials to build new equipment or accessories for the lathe, mill & other gear. Happened on your vid cause I was looking at ways to blast a couple large pieces of gear & freshen up with new paint. My local guy, bless his cotton socks, does a great job on the contract jobs I charge for but on homers it erks me to shell out the bucks when I could diy. Anywho, I’ll get to work on what you did wet not dry. If anyone didn’t know kiwis are capable of anything they’ve never met a kiwi. Cheers bro! Kiwi from Hamilton.
Would sizing the sand ball-valve at the bottom of the tank a bit smaller so you could run it fully open save on wear? It seems like having to throttle it down would expose more teflon and increase wear.
Nice video but falls info @ 26.20 dry blasting is 100% better in confined area's wet blasting messes the visor and makes sand stick near on instantly if yout having issues in tite areas dry is the way to go not wet. To get the dust off use compressed air done wet blasting needs rust inhibitors to stop the tea stain affect
love the ingenuity and look of the minion thingy ( technical term) looking forward to when you guys launch and get to enjoy the new adventures best of whishes from Oregon U.S.A.
It would be very low effort to weld a pipe coupling to the bottom of the mixer next time it's removed for ball valve replacement then weld a T-handle to the plug used to close it. Then you can quickly spin off the plug, unclog with your ramrod of choice and get back in action. Black UV-resistant "farm grade" hose is the most durable (I leave mine outdoors as sun doesn't bother it). I'll use that when my green hose wears out.
he he he, Gonna watch this episode several times, I'm getting ready to build my blaster and have been watching several of your videos to get your gear (kit?) down. Then you come along and do a comprehensive video on all I need to build my gear (kit?). Once again ma'am and sir, THANK YOU for sharing.... Oh last thing is the paint job copyrighted by you or can I copy that as well? :D
We have a big bastard three phase compressor. That’s all I know about the specs. That said we have run this off a 3hp single piston compressor but it does struggle. Two of those compressors might be good enough but they don’t last long. If it’s possible to find a big second hand unit you will be better off than smaller new units. Or big and new if the budget allows. We also have an accumulation tank which dries the air and gives us more volume in the compressed air system. I completely forgot about showing that part. I will take a quite video and send it to you via Patreon. Dame
Most blaster nozzles like the one you show here has a venturi to generate a vacuum to suck the media into the water stream. Are you using the sand blaster to push the media in under pressure? Very interesting! Do you have to play with the pressure so they don't conflict? I will be trying this soon! I've mentioned this to "experts" but they say it won't work. Leave it to a Aussie to make it work anyway. Good on ya.
This nozzle is designed to create a vacuum and be used without a compressor. Adding the compressor adds so much more power than any minor effect the Venturi design has the nozzle design becomes irrelevant. I would say ignore those experts unless they have used a vacuum nozzle with and without a compressor
How big a power washer or what pressures/volume is required for the water based blasting? Excellent and informative and helpful channel, thank you! SkipRay, Kerry, Ireland.
Hi. I just had a price to do 4 big tractor wheels and two rear mudguards in UK by a mobile guy and now I've found your wonderful video, I'm going to build my own!! Questions. Can I use a road compressor of 125cfm which I am told will give 80/90 cfm constantly as the air source? Does the size of the PRV have to be taken into account as yours did look quite small? Does the airline need a moisture trap before the sand tank? Finally, what size are the quarter turn valves - they look about half inch? Regards David
That size compressor would be perfect, we used a 35cfm and then a 70cfm both powered this just fine. Our valve was around 3/8". bigger compressor, alows bigger valve. Air trap is good but not needed. just dont let the sand sit in the tank with a load of compressed air in it over night as it will condensate and block it up, empty it or air after your finished and you'll be fine.1/4 turn valves were all 3/8 on this unit.
No not really. More air is the key ingredient but we have a monster compressor now so the system does run pretty well. Sand volume was always our biggest stop
Hi guys Damo add some big stainless bearings in the agie it will increase the volume of sand you are paying for January is not far away can't wait to see her back in the water all the best Kiwi Chris Ps will Buy a Hoody for next winter
Excellent, quick foundation of building your own blaster. Thanks for sharing

Yep. It was a real 'blast', right? 😁
I see what you did there
I took a allied services course while in the army. It said to use laundry detergent and water to wash a fuel tank out before welding it.
Yeah that would work. Bind the excess fuel vapour etc to the soap

To get a better flow of sand ,a good way is to add a small air supply to the lower area around your tank to fluidize the sand .

very good info ,best i have seen but of course it all comes back to compressor size
Would sizing the sand ball-valve at the bottom of the tank a bit smaller so you could run it fully open save on wear? It seems like having to throttle it down would expose more teflon and increase wear.
Yes it might but then you would find the machine jams more.

No not really. More air is the key ingredient but we have a monster compressor now so the system does run pretty well. Sand volume was always our biggest stop
