so i bought a sandblaster from supercheap with store credit i needed to burn, anyways, attacked my old ZxR exhaust headers with it and what a great result! it does use a lot of sand, but this can be defeated with a basic sand-trap setup. the gun says its operating pressure it 90psi, but i found it worked best at 100psi with the hopper half open. end product was a rust free manifold ready for my high-heat matte black rattle can. looks good, will post photo's conclusion: not a bad sandblaster airtool for $39 off the shelf, 10kg of abrasive sand costs about $30
Interested in seeing the results .... Is it this one? http://www.supercheapauto.com.au/on...ir-Sand-Blast-Gun-600ml.aspx?pid=214306#Cross
I would definitely like one of these, you reckon you could set up a sand trap in a garage big enough to do a bike frame?
better one is the one with a hose you can drop in a 20 litre bucket. use beach sand but wipe with rust converter soon as finished or will soon turn yellow. all sand is carcinogenic which is why the pro,s use hoods and suits. to dry sand heat in oven.i use beach sand on cost factor and collect top sand on a dry sunny day.
The big hazard with using beach sand is something called silicosis from tiny fragments of silica dust. At the very least you'd want to be using a full gas respirator with a dust filter in front when working. One of the dust only masks just wouldn't cut it. As well you'd want to be able to wet the area down afterwards to embed any left over particles into soil where it can be absorbed safely. play safe and live long peace out Glenn
blasted all the surface rust off easy, signs of usual pitting for a 25 yr old manifold exposed to weather. used high heat black ceramic engine enamel paint, works a treat! total costs: sandblaster $30, sand $20, paint $15
Hmmm .. I like that Will have to do that on the Fizz. What brand was the paint? ...... is that mottled appearance from the surface of the pipes or the paint finish?
yeah, heavy pitting, the headers have seen better days, and yeah Risky, i rode the bike around the yard untill the paint cooked in, no more smoke now so i reckon the paints set in well. paint was the cheap engine ceramic rattle can from super cheap grey.
nah love it, just decided to use the old one untill its kaput, then throw the chromie back on. besides i have a devious plan with potential, top secret ZxR shenanigans
Bumping an old thread i know. I have used a couple of the sand blaster's above, i've used the suction feed gun's where the hose hang's off the bottom of the gun and you run it into a bucket of sand. I agree with the high efficiency particulate filtered mask, Silicosis is bad. This is my first setup, it was very wasteful I found that if you were blasting higher than the bucket of sand you would pick up less sand the higher you were. I took the end off my blasting gun and fitted it back on with the pick up tube to the top Then i made up a gravity feed container for the sand which i hung above the item i was blasting I used to use dried paving sand ($6 for 20kg at Bunning's etc) When i was blasting i used a 3M mask with 2x particulate filter's. Sand get's in everywhere, in through your clothes, hair and in your ear's even when wearing a balaclava, hat and long sleeved clothing etc Since then i have bought myself a used home made blasting cabinet, i got it for $100 off Gumtree a few year's ago. It came with 40kg of bead blasting media as well. The lighting wasn't that good, just had a double 24" fluro inside, so i upgraded that to some led lighting so i can see what i'm doing. I have recently added an industrial vacuum to suck out the dust so i can continuously blast and still see what i'm doing (lighting has been upgraded again since this pic) The blaster's do use a lot of air, i have a 240v 3hp 17cfm compressor and it can't keep up. I bought a bag of 80grit Alemite Blasting media for it which is good for removing paint and heavy rust, and i use the glass bead for finer/finishing work I also have a couple of bag's of Sodium Bicarbonate/Baking Soda for stripping paint etc which doesn't damage rubber or chrome My compressor has a Snap On water Trap and on the other end of my workshop i have another to stop any water getting through to the gun. I also have a small basic Vapour Blasting setup too which run's off my pressure cleaner This is my cabinet Here's an alternater, part way through cleaning it up with the glass bead's a while ago And a spark plug i cleaned up with the Soda, before and after This is my son's PW50 frame that i customised 3/4 the way through blasting Most part's of his bike were blasted before painting, including the custom expansion chamber but i didn't get pic's I use my blasting cabinet maybe 4 or 5 time's a week to clean up stuff i'm working on Dune Buggy hub adapter's Part way through doing my FZR pipe's, and fuel bowl's
You need a bigger tank than just the compressor. I use an old house size gas bottle as an extra tank on mine to give more reserve for the compressor to fill up while I change items to be blasted.
Yeah i have 3x 60 litre tank's (1x 15cfm and 2x 17cfm compressor's here) that i could hook up and raise my storage capacity I also have an old 80L LPG tank Seeing as i do a lot of blasting and spray painting i plan to add on a condensor with a water trap after the pump and before the tank's to help remove any moisture in the system. I used to have a 24cfm 3 phase compressor with 300L tank in my workshop, but ended up selling it when i closed down my business about 12 year's ago, that wouldn't have had a problem keeping up at all.
Here is a cheap one that Supercheap sell ($100), you need to unscrew the end off your hose and check the thread size etc to make sure the wet blaster attachment will fit. They come with a Ryco style quick connect fitting, but if it unscrew's off the attachment you can get brass npt adapater's to suit from car parts place's or auto paint shop's etc Get yourself some decent hose too, the supercheap hose is cheap crap My kit didn't fit my GMC pressure cleaner but i drilled and tapped the end of my hose to suit the wet blaster thread http://www.supercheapauto.com.au/Product/ToolPro-Pressure-Washer-Attachment-Sand-Blasting-Kit/370470 The Karcher Wet Blast kit $125 inc delivery http://www.ebay.com.au/itm/Karcher-...632669?hash=item3cf53fbc5d:g:G0YAAOSwv0tVBW26 Universal Wet blast kit, $118 inc delivery http://www.ebay.com.au/itm/Pressure-Washer-Water-Cleaner-Sand-Blaster-Nozzle/131804282036?_trksid=p2047675.c100005.m1851&_trkparms=aid=222007&algo=SIC.MBE&ao=2&asc=39923&meid=8721ec95ff844afa9ff627d0cc004818&pid=100005&rk=2&rkt=6&mehot=pp&sd=261812632669 Aliexpress have them too, search wet blasting, wet sand blasting, pressure cleaner sand blasting, aqua blasting etc etc Some of the cheaper kit's don't come with a nozzle insert though so that add's to the cost The Ceramic nozzle last for a long time, the steel nozzle's eventually get bored out from the fricton of the sand
