How to: Remove Weld Seam & Telescope Tube Steel

oh hey what's happening there youtube it's brian house here for housework and today we are going to make a quick video about removing the weld seam on the inside of tube steel and then making it telescope and this might seem like an odd video to make but i get this question all the time about how i do it and what my process is and i have some pretty strong opinions about how it should be done based around a few parameters and we're going to go over all that and talk about that now you may ask yourself again why why are we doing this well specifically this was the thing i had to figure out when i first started prototyping industrial machines and right here on youtube about a year and a half ago i built my first 2x72 belt grinder that ultimately exploded into me kind of switching my career into creating content right here on youtube and building a business called house made industrial uh we now build uh and build kits for 2x72 boat grinders and i'm sure you are all aware about the revolution 2x72 bulk grinder we put out the plans the kits if you if you would like to find out more about that you can go to my website housemaid.us and you can check out all that stuff but one of the primary reasons for this video is because without this this was kind of like my first step like i had to learn how to make this happen and and there's so many people who watch this channel now that are actually uh working and designing their own projects and i don't know how many of them actually fully understand the process and how i do it so that's the reason why we're going gonna put this video together today by the way two by two tube steel and one and a half inch tube steel it slides into each other perfectly with the weld seam removed in the two by two and you're gonna pay about five dollars a foot for any of this tube steel at the time of this recording uh to me that is a very inexpensive way to start building machines you know if you can think of anything that needs a receiver uh and an arm that's what this process is is to start this process you need to learn how to do this so anyway i'm blathering on why don't we just get started screw it let's do it all right let's take a quick look at some tube steel here these are just some small pieces these are this is the secondary tooling arm for the revolution grinder goes on the work rest and this is the receiver um you can see here there is a weld seam down in there okay and and that stops the telescoping you know from happening it almost fits but because that weld seam is down in there uh it is actually uh stopping the process of this to happen so we need to obviously remove that also this is a 10 inch piece of tube steel again this is quarter inch wall a lot of people ask me why do i use quarter inch wall and all my stuff and and they're having a hard time finding it the reality is it's not that tough to find it's just you got to call a steel distributor and ask them for it they'll cut it down for you even but the reason why i use this is because you can drill and tap into it and it'll hold a tap uh threads so there's not a real reason uh to to weld on nuts and do all that extra work you can just drill and tap right into this and it just so happens that they actually will fit inside in fact i've got one i've got a grinder body here you can kind of see how this works so as you can see the tolerances are very tight uh you know if you drilled and tapped to put a a nut into this you would be able to uh you know obviously stop this from sliding in and out it's a really kind of a cool setup and like the amount of steel that you have here is probably about 20 worth of steel to make this actually happen so you know let your mind go wild with what you'd be able to accomplish with just these simple pieces of tube steel the one barrier is that weld seam that's up inside of there and that's stopping the process from uh you know us being able to do that so we're going to talk about what we need to make this happen all right so you can see that the mill scale is removed from this piece of tube steel right and all my tube steel so how i do that is i use an acid bath i soak all of my tube steel for 24 hours minimum before i do any of this believe it or not that mill scale that's coated on all of this steel is part of the reason why it actually will not telescope okay and in fact you wouldn't think it but there is mill scale down on the inside of this two by two so by soaking it in acid it actually removes the milk scale not only from the outside of the tube steel but also from the inside of the tube steel and the reason why i use vinegar is because it's non-toxic it does the same job as muriatic acid although it does take a little bit longer i prefer vinegar because i just leave it in the tank i use it and just use it use it use it and it doesn't bother me to have it around and it does the job just fine it takes that mill scale off of the surface of the outside but also the inside which is actually really important so something to think about and otherwise if you've ever tried to grind mill scale off of anything you know it gums up your pads on your flap wheels it's possible it's ugly i personally don't like doing it i'm building machines that are industrial but i like them to look cool too at the end so that's my process all right so now you're asking yourself all right get on with it and everything else and like brian what kind of tool are you actually going to be using to do the work and i love a pneumatic file now you don't have to go this route i mean there's lots of different versions of this out there you don't need to even use a pneumatic version of this you can use an electric version of this this particular one i get on amazon it's like 75 the reason i love this tool is that it is not a single use tool it has so many other functions i smooth out the insides of tube steel with it i texture knives with it um i can make fillets in my welds with it there's just a whole slew of things you can do with this tool and the electric version of this on amazon which by the way i'll put links down in the description it's like 35 bucks right so i mean you know there's really no excuse to not have one of these in your workshop i will say though that you're going to want to get the good uh the good belts for it this is like a 36 grit belt i'll put a link down in the description you can get these on amazon and all over the web it's a half inch by 18 belt and this is just such a fantastic tool and it works really great for removing a weld seam on the inside of tube steel all right now that we've got our tube steel cut to length and we've got it soaked in vinegar we've also rinsed it down got all the acid off of it i use windex or of apple rust just to neutralize the acid we're going to do we're going to start with a short piece this is going to be the receiver and this is going to be essentially the piece that we want to slide into this i like to use a vise for this you know just throw the piece in there usually with the weld seam on the bottom that seems to make the most sense clamp it down doesn't have to be super tight i want to make sure that i've got a brand new 36 grit belt on my pneumatic file whatever version of this you use electric or pneumatic whatever and then also you're going to want some ppe hearing protection is always a must and also dust protection all right so what we're going to do is we are going to insert the spinning pneumatic file down and across the weld seam and we're going to do it kind of slow that's the counter-intuitive part to this is that you would think you know going back and forth real fast is going to actually get rid of it quicker but the longer you take to go down and in the more consistent you're going to be with removing that weld seam what i find is a lot of times as i'm removing it it it feels like i've got it all the way down it'll slide most of the way in but then it'll hit a high spot so we're trying to avoid those high spots [Music] all right so now we're going to give this a a shot you can see that we can slide this in and out pretty easily but we're also going to turn it 90 degrees and just check to see if we can do it this way and and we can so we now know that for the most part any which way we decide we want to put this tooling arm in there that it's going to slide in now in this one particular way this is kind of odd but in one particular way this is going in it gets stuck so there's just something that's rubbing what i like to do is look to see where the you know the rubbing is happening it's typically happening in the spot like this and then we could just take a quick uh little sander and sand down those edges just to kind of get it to fit right but yeah that's a success that took all of about one minute or so to get that out of there okay you can see i uh just took that pneumatic sander used a 40 grit pad and i took these high spots down one of the really cool things about working with metal is it's similar to woodworking you know it's you can sand steel and grind steel but it's it really is forgiving and it's almost in a way uh easier to work with than wood in my opinion i i really do love working with steel because you can manipulate it and you know if you mess something up you can always pretty much fix it but anyhow so i took those high spots down and you can see now we're we're not in having those same challenges with uh inserting the tube steel into the two inch and i can rotate it in every direction and it will slide in and the tolerances are looking pretty good so that is a success well there you have it guys this is a super simple way to remove the weld seam from any tube steel and i hope i have convinced you that you do need to own some sort of electric or pneumatic file i think every workshop should have one and it's a really super important part of my process of building and prototyping
