Avid CNC Ep2: Dual 4" Dust Shoe

today is dust collection day for the CNC machine so this is a six for four pants branch and it looks like a or pants why it looks like a pair of pants so they call it a pants why this has got two four inch ports on the bottom one six inch on top or hose adapters I should say and I'm taking inspiration from Frank Howarth for this this is just temporarily secured up there with a bungee just so I can kind of figure stuff out I have to still figure out how that's going to be attached but I'll have a dust shoe on the spindle with two 4-inch ports on it so the two four inch ports will come up into that and then a six inch hose this hose over here will attach to that this six inch hose is bungeed to the rafters temporarily until I figure out how I need to make adjustments after it's all hooked up and that goes into another branch of the actual dust collection piping and I put the blast gateway over here so that as I'm switching these blast gates for other stuff it's conveniently located right there I can switch them all in the same spot rather than walking all the way over to the CNC machine it is way up high I can't reach that so I have a stick with a magnet and tape wrapped around the magnet so it doesn't shatter the magnet very easily open and close that blast gate super simple but today I'm going to tell you guys how I went to the process of making a dust shoe for this and prototyping it with various versions I made a lot of changes throughout the prototyping process I'm just going to gloss over what I did so this is the first one out of quarter-inch plywood just to get something physical in in place so I could look at something and physically see some changes so I wanted to verify that I had some had enough space back here on the backside of the spindle before it interferes with the z-axis I wanted to make sure that these holes were the correct size which they're not on this one my plan was to mount these from the bottom they're not the right size so I need to make an adjustment there then of course the size of the spindle this fit the spindle but it was super tight so I needed to loosen this up a little bit and the way I wanted to clamp it to the spindle is by cutting a relief right here with the bandsaw and then a bolt or a screw going perpendicular to that so that I can tighten it down and clamp it reducing this diameter onto the spindle so I learned a little bit from this one on to version number two version or two is very similar but 3/4 inch plywood made a couple changes to reduce the size and also increase a little bit of mass around the magnets here just because I thought there wasn't much material here so may did that change these holes are still not the right size but I figured if I'm gonna use 3/4 inch plywood for the top plate well that's gonna leave me enough material to mount directly to the top of it with these these ports so this flange has mounting holes that'll be super easy so at that point these these don't matter anymore my adjustment to this made it too loose so it was with a clamp right here I could just barely put enough pressure to get this to tighten up so I needed to go in between my adjustment there as far as getting that a little bit larger these holes for the magnets were too tight I could not get a magnet in here so I needed to make that adjustment and I figured let's get the dust hoses as close to the spindle as possible so I made a note to move this in by 1/4 of an inch the rest of it yes seemed ok so version two done version three and this one the diameter for the spindle was perfect with a regular washer head screw this is actually a two and a half inch long pocket hole screws with an added washer down below it just to prevent this part of the plywood from splitting and I kind of drilled it off angle after the cut was made so it it wandered on me a little bit as I tightened it down but this screw tighten it down perfect it was very very tight now I'm a little hesitant to use a screw here into plywood because if you're if you're gonna adjust something then you want to have basically if this has removed a couple times then you lose a little bit of precision in your hole with screws versus a bolt that would be a little bit more longer-lasting than again how often am I going to remove this very rarely and if it is plywood I could always cut another if this ends up not working but in this case it clamped down just fine the holes for the magnets are perfect and I think yeah right here I actually still have a magnet in place so that's that works out just well these holes are counter bores so they will I can push the magnet down so that the bottom surface of the magnet is a quarter of an inch away from the bottom surface of this plate so that a steel dowel can go in there 1/4 of an inch the dowel will hold the bottom plate to the to this surface and also that the steel dowels sticking into this plate will stop this from shifting around so that's a registration the method of registering these two together let's see so with this done I decided to figure out a little bit of work on the bottom plate for the brushes so let's talk about brushes the first one I ordered was this one it is too short I bought this based upon a recommendation in an online forum without taking into consideration the changes of their design versus my design so I just blindly ordered it it's too short it's got a rigid back here so it's metal just fold it over but the length won't work so I ordered the second one this one is much longer it's three inches but as you can see it is ridiculously flimsy way too flimsy for dust collection I put this around one of my 4 inch flexible hoses that I have here in the shop and all of these brushes just fold it over with no problem whatsoever so while this is a rigid back it would Bend around all this shape just fine it's too flimsy wouldn't work so version number three that I ordered or brush number three this is much stiffer does not deflect much at all with the dust collection which I like and it has a rigid back I didn't know how the rigid back would work so I figured if this is the one that I'm gonna try I might as well cut out a quick bending form so this is the size that I need the interior size that I need this to bend around so I could clamp it bend it around and will that work well kinda I don't know if you can see but all right there you can see so it does Bend a little bit around here but due to this basically being a triangle profile of just metal folded over on to both sides of these brushes it bended around but it also bent downward and upward I could not get this to Bend cleanly so all that to say this is the brush that I'm using but I'm not going to use a radius to go around the port instead I'm just going to make a rectangle with this so version number four of the prototype which i think is the one that I'll actually bolt to the machine and use or screw to the machine in use this is the top plate let's get this out of the way this is number four this is the top plate too many pieces apply with a round now I have not cut the slot yet for the spindle I wanted to make sure all the dimensions worked out now you'll notice I went down to four magnets instead of eight because I figured that these are the magnets that I'm going to be using and these are the steel pins that I will be using this is plenty strong enough this has a lot of pull with just one now I understand if you have multiple magnets stacked up like this your your poles going to be greater but that also tells me something with this just having one magnet on it it is kind of pretty easy to pull off I think just one magnet and four of these will still be fine but if it's not strong enough then I know that I could always stack more magnets there's plenty enough room inside these counter bores to stack multiple magnets and get a lot more pull so steel pins they will go in the bottom plate referencing off or connecting to these magnets here so I switched from eight down to four and I moved them in a little bit closer so this is like I said the top plate not much going on kind of a rectangular shape this is the bottom plate and the front side is facing you on the camera so the bottom plate will have a handle on it so I can pull down on the front kind of suitcase looking so I'll pull this down to pull the bottom plate off and on this one I cut a 5 16 7 inch groove this is 5/16 by 5/16 and I've got a rectangle here for the brush to go inside it the magnets are now inside the brush which really doesn't make a difference at all but there is one thing to note with this groove for the brush I want to make make it as difficult as possible for the dust to leave this center area so what I did is made sure that these shorter pieces are extending further than the long pieces so that as the dust is created or chips are created in the center they're gonna have to come out and then go on a sharp angle to get out of this seam if I was to do it the other direction the other way where this piece is extended further than these short pieces and there would be a slight gap right here assuming that this isn't perfectly tight and a much easier more direct path for the chips to go out of this gap so this extension really does matter a little bit in my opinion all that to say I think I'm ready to cut the brushes and stall it put the magnets in install those and the pins bolt this up and see what we got on the top of the top plate the magnets can be pushed in with one of these hex driver extensions all the way down to the bottom of the counterbore should be pretty easy to do this all right so now the bottom of the magnets is resting on the bottom of the counterbore exactly quarter of an inch away from the bottom surface so that means the height of the steel pins needs to be somewhat precise and to put these steel pins in here at a precise height we're going to use the actual magnets so let's get these pins started way higher than what they need to be now there's enough friction here that these should not move under normal operations but if they do move well then just a little bead of superglue should stop these from moving so they need to be about a quarter of an inch tall a little bit more than that because I'm going to use this top plate pushing the dowels down so now the dowels are referencing off of the magnets and I can push down to make sure that they are the correct height until both plates are flush with one another all right so now let's see we got the dowels actually sticking through the bottom side just a little bit which is fine but I need to get something to elevate this so that there we go magnets bottom out pushing the dowels as far as they need to go now we have a top plate and a bottom plate at exactly the correct distance away from one another and that locks into place I think I think I want to put another magnet on each one of these it just doesn't feel enough yeah needs one more magnet too is a lot better so this is kind of interesting these bristles are actually twice as long and they wrap around a steel dowel to come out the other side and then this piece of metal is just clamped over the top of it so that's how that's made I lost a couple bristles out of the ends after I cut it so if you use this material you have to come back and crimp the end so more more doesn't come out but this should be a pretty tight fit so I don't think epoxy or anything like that is necessary easy to start but I think this will be a little bit of effort to get it fully seated alright let's jump ahead a little bit the bottom plate to all the brushes are on and the top plate I went ahead and added this screw so I drilled the hole for the screw first then cut the slot so that way the hole doesn't the hole lines up before clamping and I also cut these ports down just a little bit on the inside so they'll clear the spindle and secure them to the top with some tiny screws so this is ready ready to be mounted alright I've got the top plate secured to the spindle this is easy on easy off and all of this getting these small hoses with little wiggle room all connected was testing my patience a lot of frustration there but it's all hooked up I don't know how I'm gonna secure this just yet so a bungee is the temporary solution I don't want to put much stress on this drag chain so we're just gonna kind of you know go with the flow and see what happens now to hook up the large pipe or large hose rather and go from there oh but to do this because the dust collection hose is coming in from the front side of the machine the main drop I need to put this as far away as possible to know how short to cut the hose so all this needs to go in the back left corner before I go any further okay so the dust collection is pretty much done I've got to find a more elegant solution to hold this piece up against the spindle area I'm using two bungee cords right now and it works but it's not the it's not the most elegant thing in the world the magnetic shoe is working I've actually already used this to cut a few things and to test everything out everything works fine the the extra six inch hose that we have doesn't get in the way of anything [Applause] so I have it off to the right hand side where it drops down from the ceiling so that it could go anywhere inside the cutting area and not basically twist the hose around the the spindle as it's up or down [Applause] but I've got a few things and the dust collection works really really well so why did I go with two four inch hoses ports rather than just the typical 1/4 inch that you see on a CNC machine well because I have a six inch drop right above the CNC machine 6 inch branch coming over here and I've got the capacity to run 2 4 inch hoses on it this is the only thing on this side of the shop so I might as well use both 4 inch hoses that much capacity so that's why I went with that and not only that but more dust collection is never a bad thing I absolutely hate dust and this thing sucks which is really good so if you are interested in this particular design you go to my website I'll have a link in the description if you're watching this on YouTube and I'll have a free download for all of these vector files as well as a vCard file that I used to export my own g-code also if you're interested in a single 4 inch dust collection port you don't necessarily have to or dust collection shoo you don't necessarily have to purchase one there's some readily available ones that you can purchase but you can make your own and save a ton of money go to the avid website avid CNC which is CNC router parts Kampf I'm not mistaken I'll have a link down below to their dust shoo on their website if you search in their search bar for dust or dust shoo scroll to the bottom you'll be able to find it's a free tutorial on how to make your own out of HDPE I believe that's the material they also have all of the shopping list that you need but rather whether or not you want to use HDPE or some plywood and ports like this you can download their free files and that's a fantastic starting point that's what I used to start mine and then I just modified here and there to fit it to my exact needs I think that's it next up in this series is going to be the spoil board which once again I'm waiting on shipping delays [Music] whenever that comes I'll get to that aspect of the building after that the CNC will be 100% ready for furniture which I am so excited about the spoil board is going to be really interesting with both t-track as well as some 20 millimeter dogs for repeat locating and be able to back shot a lot of stuff really quick and easily I'll have a vertical table as well I'm just really looking forward to it so if you want to be notified of when I publish that and go to my website Jase Custom Creations comm slash newsletter sign up for my email newsletter and you'll be notified when the next video comes out next article next whatever I'm rambling you guys take care have a great day and I'll talk to you the next video
