Please Note: Sand contains silica which is dangerous to breathe in so make sure you use a N95 rated mask as a minimum. A much safer option you can buy proper sandblasting media (from Bunnings) which does not contain silica but you will still need to use a mask as the paint and dust are still dangerous to breathe in.
Steel and iron produce slag the is skimmed off. It is ground into sand size bits and sold in the US States in home improvement stores for cheap. It is sharp with jagged edges and reusable. Take 3/4” (19mm) metal electrical conduit, cut and weld a square frame to fit a large bucket. Use heavy pet safe screen for doors, stretch and tape temporarily and cut to get a full wrap. Using PVC pipe of 1” (25.4mm), cut it down the middle with wood working tools and cut just over the half way point. It will clip over the conduit-screen strainer to clean sticks, chunks and general debris to be used again because I am comfortable broke, this works. Placing a sheet of plastic on the ground make recovery much easier. For the pickup tube, it works much better if time goes into two tubes of metal conduit the fit your suction hose. The inlet side is 1” (25.4mm) shorter than the hose side. Place them about 7/16” (11mm) apart, equal at the bottom. Mark and drill a hole connecting the tubes at the bottom and solder in a 3/4” (19mm) metal fuel line. Close the end of the inlet tube at the bottom below the connecting tube using vise grips, hammer or a vise! Drill 2 holes in the hose tube one above the connecting tube and on about 2” (50mm) from hose end when fitted. A strange as it sounds, it increases the velocity of air and increase suction inside the tube even with the hose tube open at the end. A video showing 5 things to make a better sandblast cabinet shows this in detail. It works in a bucket a well. Keep the air dry as well. Check you technical information or ask the paint supplier but many epoxies do not have “UV” protectants mixed in. Yes, it is under the bottom where the sun rarely shines, but after 3 coats of mixed “A & B”, who wouldn’t want it to last 3-5 years? If you have a urethane based clear that mixes with an activator or hardener, flat or glossy, it will provide a tougher rock chip protectant than straight up epoxy. An option that is huge in the US States, is to spray with U-Pol black bed liner. It creates a texture that you control somewhat, but has “UV” and protects from rock chips and salty water. It helps a bunch. Best of luck to all. DK, automotive certified ASE Master Tech since 1978, Retired, but working because I am comfortably broke!
If the bucket of sand is elevated and the hose goes through the side of the bucket, it sorta mimics a gravity hopper and blaster gun performance will improve. Siphon blast guns are a pain and their performance can be enhanced, Kudos to Sir Issac Newton for discovering gravity.
Hey mate, How would you go about doing the chassis under the cab? Would you recommend lifting it off? If so, how? Restoring an HJ75, preparing to go ahead and do the same as you. Do you see any issue in once sand blasting, spraying a coat of rust converter, then doing the chassis paint? Any other tips regarding restoration would be much appreciated. Keep up the good work! 👍🏽
I would like to know how to do sand blasting below a Ford E-450 box truck under the rear bumper until the rear wheel without to remove the box truck please?
how longs this last till rust starts popping back through or have you got several years with this method or anyone else ? looking at doing my 75 series soon :)
Honest review. Dude. You gotta get excited or something. It’s a very informative video and I think it would do better if it wasn’t completely monotone. The intro was what hooked me. It was amazing.
Thanks for the feedback mate, looking back at this video my voice over is pretty bad😅 I will try to improve it when the new videos come out this year. Cheers
The easiest way would to improve the setup would be to have a bigger compressor but thats about it for the non-professional. If you wanted it to work better you would have to hire the professional sandblasting gear usually from Coates hire or similar but that does get expensive
I restored an FJ 45 years ago painted it in Acrylic dune beige, took it to a car show swap meet a bloke pulled up next to me in an HJ47 done in 2pack it looked like glass he was sort of smiling at me then looking back at his when the time comes to be judged I won first prize, the bloke next to me went to the judges asking why he didn't win, the 3 judges turned around and said they were never painted in 2 Pack and were never that shiny so i had the last laugh i am now restoring an FJ 45 with a turbo diesel and 5-speed gearbox disc brakes mickey Thompsom Baja tyres allround snorkel ect. then i have another FJ45 i am putting a common rail 3-litre turbo diesel in it out of a Toyota Hilux with Auto box
Does the poxy spray protect chassis from rust? Just go up to di and back and don’t drive through the water, can you also spray over a black paint on your body? My chassis was sprayed black when I bought it? Cheers legends
We used one 20kg bag and still had some leftover, just depends on how much work that chassis needs but if you do it on concrete you can always sweep up and reuse the sand
They used a portable sandblasting bucket made for supercheap auto stores. Don’t know if you in Aus but they’ve put them on clearance and I just picked one up for $35.
Not enough to create any issues. The sand we used from Bunnings is washed and contains less then 2% mineral and organic impurities. I would be more concerned about missing a spot when painting 😂
As an expert, I can tell you that you are not using high enough cfm compressor. There should be no visible scale, or flash rust at all with a single pass.

Sand blasting with normal sand can cause Silicosis.
Well...glad you brought that up.
What size of air compressor did you use?
Cement mixer and a gas heater blowing into it for drying sand. Used to use this when paving to get dry sand to go between pavers👍
Thanks for the tip
i wire brushed my 75series and sprayed rust converter after 2 days epoxy primed the chassis and sprayed 2k black looks good

Great Job, Thanks Dude, I learn a lot from that strait to the point vid.
You don't have to primer before painting?

Updates??
Ended up doing KBS and ended up owning a 40 series 😂 don't highly rate KBS the best way I've now found id 2k epoxy followed up with a satin 2k
@@TRolla82did you do the whole 3 step kbs process??
Good video mate, keep up the good work.
Been waiting so long for this vid
How long did it take you to do from start to finish
From what i remember around 5 hours

PPE bro... Take care of yourself. Thanks for the content
how much did you have to thin down the rust guard paint?
Does the poxy spray protect chassis from rust? Just go up to di and back and don’t drive through the water, can you also spray over a black paint on your body? My chassis was sprayed black when I bought it? Cheers legends
KBS is also a very reliable and high quality coating for doing chassis.
What about inside the chassis
How many bags of sand would you say is required for a chassis this size?
We used one 20kg bag and still had some leftover, just depends on how much work that chassis needs but if you do it on concrete you can always sweep up and reuse the sand
The size of the sand blaster please
Getting rid of the rust tinge, overkill 🤣 not overkill but a proper job
How to clean up inside the chassis? It usually rust n rotten from the inside
I was just thinking the same thing also how do they do the front the chassis I imagine it’s a lot of work taking of the front of the truck
Luv my t-shirt guys 👍👍😎
sanblasting chassis good job
What grit of sand did you use?
Just normal bunnings play sand
Anyone got a link to the gun they used ?
They used a portable sandblasting bucket made for supercheap auto stores. Don’t know if you in Aus but they’ve put them on clearance and I just picked one up for $35.
Thanks
great job
Hold on......... you said as good as new, like they come from the factory!
Pretty sure they didn't prime them with rust in the factory..?
Nothing comes close to dustless blasting. This frame would be bare metal in 20 minutes
Good
That must take an absolute eternity
Took less then an hour, so not too bad
Do not use sand as it also contains salt which you are then blasting into the steel to create rust further down the line
Not enough to create any issues. The sand we used from Bunnings is washed and contains less then 2% mineral and organic impurities.
I would be more concerned about missing a spot when painting 😂
salt itself doesn't cause the rust. Salt acts as an electrolyte with the water and increases the rate in which the iron turns into iron oxide.
As an expert, I can tell you that you are not using high enough cfm compressor. There should be no visible scale, or flash rust at all with a single pass.
Agreed but that was the only size compressor we had at the time
@@Buildin70s been there, try smaller but longer nozzle with smaller compressor. Speed+distance=power
