Making a DIY sandblaster

so neither fellas right in today's episode we've got something new and fun in store for you now allow me to explain what exactly made me want to do this then we'll figure out where to go from here anyways so I was chilling in my garage where I found this thing right here so this is a vise which you can use as a portable sort of instrument or mount onto a bench for example right now we're restoring a motorcycle and this is what's left of the rim I did try to clean it with an angle grinder yesterday but the rest is so bad that it's impossible to remove which got me thinking you see we could really use a sand blaster around here I'm sure you all know what that is and how it works suffice to say that it's an invaluable tool in our trade if you need to give something a thorough clean it's actually a pretty simple device the only difficult thing was finding an empty guest cylinder well we did find one so it wasn't too expensive as for the rest of the parts you need to make all of this work they're also not particularly expensive seriously the priciest bits were well again this here cylinder and right here I've got a bunch of I put together an assortment of useful supplies these are mostly valves tea pieces and some foam tape I am seriously keen on putting together a sandblaster I don't know why I haven't gotten around to doing it I mean it's a very useful thing in anybody's garage if you need to clean something off it'll do you're right it'll make a really quick work of removing any sort of rust and whatever the rate I see we put together a sandblaster I've actually never used one myself anyway we'll see how it works what it's worth and whether it is indeed useful or not so much let's do this alright fellas the hardest thing we had to do the rule was removing the valve from the looks of things it's been chilling here for a number of years it was so clingy that we were barely able to extract it these things happen what matters is it's out now as you might imagine hacking or welding this cylinder as it sits isn't an option since it does still contain some residual gas though it might seem as if it were empty when as a matter of fact that's not quite the case and believe me when I say that that residual gas is more than enough to make this a really bad day so in order to cut it to pieces we will need to fill it with water first I've done this stuff a number of times there is really nothing to it we just need to fill it to the brim with water that's going to allow us to carefully start hacking away ok let's get to it making a DIY sand blaster translation and voiceover by beyond my Russian right now we have a filler neck to pour the sand into now there is the matter of drilling a hole in the side which will we'll use it to feed air into the cylinder and get some high pressure going but you see we need to create a bit of pressure in there to attain equilibrium to loosen this end up we're gonna need to make another hole down there well done a fitting through which the sand will exit the cylinder it's basically going to make it into it'll be fed into the hose at which point you just point and spray but we still have to get to that part of for now we just cut and drilled all right yeah we can just cut right around this weld awesome we don't even really need to try that hard here we just need to cut around the line over there fits beautifully and then we just weld all the way around [Music] oK we've chopped off a piece it's nice and smooth doesn't seem to be any wobble we can go ahead and weld it on [Music] all right we've welded on the pillar neck that's good or maybe I should call it a loading neck anyway now we just need to yeah right about here we'll drill a hole which is where we'll be welding a fitting we'll attach a valve through which will feed the cylinder with air and increase the internal pressure plus one for the sandblaster gun itself in any case we'll get a better understanding the further we keep going we'll start with some drilling immediately followed with some welding hood I mean why wait okay so here I have the fitting which is a half-inch that's for the pipe if I remember correctly it had an external diameter of about 21 milling that should make for an internal diameter of 16 meaning we'll be making ourselves a 16 millimeter hole oh right it's full of water well it's not going to be that terrible of a flood [Music] [Music] okay what do we got here we have wood used to be a guest cylinder with a big boar neck up here over here on the side we have a half inch fitting plus we've welded on another fitting down here which is also a half inch in diameter [Laughter] [Music] check it out fellas we've given it a pink job the beam is nice and dry it does look pretty different we decided to color it black and now all of the fittings we've welded on except for this big one need to be connected for that we're gonna be using this here hose this one is 20 mil I've also good so right here weed where are they oh here they are right here I've got a set of filler nozzles which are also 20 mil in diameter we'll use a bit of foam tape to get a tight seal and now we need to get everything hooked up right let's do this [Music] [Music] check this out fellas we've put everything together it's all looking good as for how this thing works it's all very simple you feed the compressed air through here under pressure yum and right here when I visited the store I couldn't find the quick release fitting with half inch thread maybe they just temporarily didn't have them in stock when I was there so we've connected everything via hose and hopefully it keeps it together I'm guessing it should I mean we often connect hoses in this precise way and things usually seem to work out okay anyway so we open up the valve compressed air enters the cylinder and right here we have a second hose we open up this valve and at this point we already have pressure inside the cylinder we have pressure in this hose we get up to this TPS and it's all fed straight into this hose right here the pressure here is exactly the same as it is inside the cylinder okay so we figured that out on this end we will have a jet which is going to be closed off the entire system will be under pressure meanwhile this valve which is located way down here it's going to be adjusting you open and close it to control sand flow or instead of sand you can use this stuff which I bought it's called copper slag and I'm really keen on trying it out you see the parts we need to sandblast would if we were to spray them with sand that'd be just it's just gonna take a really long time to clean them off copper slag greens are somewhat bigger plus it differs from sand in that regular beach sand granules are round while these actually have sharp edges when this stuff comes into contact with metal it's way more effective in cleaning off rust dirt and everything else now the interesting part time for us to put the jet together you've do it it's actually made using an automotive grade spark plug you have to hack the metal bits off the plug leaving just the ceramic part then we take a disk for grinding ceramic granite and carefully start hacking you need to cut right before the white part of the ceramic piece why so that's so we can fit this plug to the valve that's when I take a simple 1/2 inch plug I've got one of those right here so I'm gonna be drilling right through it right what's the diameter 12 mil fantastic I guess I'll use a 12 point 5 millimeter drill bit maybe even 13 mil which doesn't matter I mean it's not like this piece is going anywhere we'll install a seal right here I reckon one from an oxygen hose should do okay we'll chop off a piece of hose insert the plug well I mean the ceramic fit that we have left from the spark plug then we'll take this plug which will act as a sort of hold down nut and use it to well hold everything down we have yet to sort all of this out I think you let's quickly finish the job and I am just itching to start testing this thing [Music] okay fellas check this out I've drilled through assembled everything you saw me slip that bit of hose in but as I'm sure you can see after putting it all together and tightening the nut the ceramic bit is slightly off-center just a tiny bit that's nothing critical I really don't think it'll make that big of a difference I reckon it's still going to work so for starters we'll have to try it out well the reservoir is empty almost since so the thing is that our air compressors can get the pressure up to about 10 atmospheres and though these hoses are reinforced I have my doubts about this well it's not that I have doubts I just like to check and make sure that they'll hold up okay I mean it would be pretty unpleasant to see it all go kablammo when there's a good 5 to 7 kilos of sand packed into the machine we wouldn't want that to fly in every direction right so for now we'll do an empty test so assuming this works we'll head outside and do some sandblasting right now we check to see of these hoses and everything else will stay in one piece it's blowing pretty hard and that stream is going to contain either slag or sand this should be pretty good [Music] okay so I've brought everything outside well but you know now I'm aware of the fact that you should take to the safety measures very seriously I've got my jacket I've got my hat and that's as serious apparel as I've got I'm afraid this isn't going to help but oh well they're these gloves I don't think they'll help you either you'd be better off with a pair of welding gloves and here's that vice that I wanted to clean off there we go well at least try to secure it to the table awesome right let's give this a try opening the valve well something's coming out your Wow I just made a hole in the table holy crap okay now check this out [Music] now check out the speed at which its flying out doesn't it look great now we've cleaned it off it's looking good it's ready for some clearcoat all right so now we need to try and just put cleaning this rim I'll go ahead and place it right here [Music] no other had what can I say here fellas I actually wasn't expecting this sort of effect this is one very useful device indeed now how long would I be doing this with a wire brush on an angle grinder or on a drill doesn't matter whatever the case it would have never scraped off this old and deeply rooted rust it would have easily cleaned up this soft and thick upper layer but as for the indentations and all that other stuff it wouldn't have even gotten in there but in our case this thing is unbelievably effective will do so while I was at it I tried cleaning off the paint and it comes up just fine mom in the vise looks like it's brand new there is one thing I need to do it just became clear to me it's actually pretty cold outside we're expecting to see some rain and the air compressor apparently isn't fitted with a water separator and that's not good the air has to be treated and it shouldn't be human and with these long hoses we can't tell for sure whether there's any condensation for me a bit of water does find its way in which I'm sure you've noticed on the footage in any case the copper slag is being fed so there's that we're all good with the air we did see the nozzle coughing somewhat whatever what matters is that it all works pretty well so yeah I'd say that this is a pretty useful device that said safety should always be a big concern I mean these gloves if you were to spray your hand by accident they're not gonna help you you need something much more robust like from deerskin or something it's good maybe even from some kind of soft material so that when the sand comes into contact with the fabric it doesn't punch right through you saw how quickly it made that hole Morgan yeah this is a nice piece of kid honestly why didn't I make one sooner it makes it just so much easier to clean off your dirty old parts you don't even need any wire brushes just load this end connect the air compressor go outside and give everything a quick queen and then there's the fact that you can reach spots that you physically won't be able to clean out using a brush I mean the particulates fly out with tremendous speed scrubbing everything off upon contact will do awesome anyway fellas that's all I have for you but if you decide to go this route make sure to be careful then I assure you you'll see a 107 percent success rate right let's wrap this up watch us subscribe send in
