Mobile Air Cleaner Cart - 247

hey folks my plan for today is to turn this Old Furnace blower motor and some filters into a shop air cleaner the blower motor is actually a three-speed motor but I'm only going to use the slowest speed I've removed the motor from the enclosure to look at the wiring diagram and check out all of the uh motor ratings uh hooked it up for the slowest speed and checked it with my ammeter with and without restrictions and all of the amperage levels are within uh the the specifications on the side of the motor so we're all good there now for the filters I'm going to be using four single stage filters uh each one of these are 20 X2 filter and they are rated at MV 13 filtration and I actually saved $35 by buying a box of six online rather than buying four at my local home center now also these are rated at MV 13 the ones at my local Home Center are just best whatever the best filtration level is uh for what they provide so saved quite a bit of money by buying these online so why am I building a cart instead of a air cleaner that typically hangs from the ceiling in wood shops uh that's because uh two reasons number one I want to be able to bring the filtration closer to where I'm working at mainly the lathe if I'm working in here with the lathe uh with the garage door shut I want to have some air filtration right next to the lathe especially when sanding and number two uh I want to use the exhaust from the blower as a fan even with this uh air conditioner in my shop in the summertime it still gets a little bit warm occasionally and not necessarily cooling the the space uh but circulating air really does make a big difference so uh it's going to kill a couple birds with one stone as the saying goes uh my original intentions were to use the cart as a grinder stand but I was cleaning off my my assembly table one day and moved my grinder to where it is right now below my drill press and that seems like a happy place for it to be so that's going to stay right here I don't want to if all possible just have this cart sitting by itself I want to use it and maximize it in one way or another and I don't have another benchtop tool to sit on top of it so the next best option is to replace one of the carts that I have currently to make it a little bit more useful here in the shop this is my planer stand planer cart uh and it's just a Cy lever design that has a bunch of these arms that stick out in the front uh kind of kind of to act as shelves without the bulkiness and you just lay crap across them and I say lay crap across them because that's pretty much what I do it's a catch all and I just put stuff everywhere uh on this thing that doesn't necessarily belong here so uh this is a good candidate to be replaced and I'm not going to destroy this particular cart because it is a good cart it's a handy design and I know a friend of mine who can use it in his shop so out with the old and in with the new one the design I came up with is extremely simple there just four legs which happen to be 2x4s with rabbits on two sides and inside those rabbits along the bottom will be four plywood panels inside those rabbits along the top will be four single stage filters the top and bottom are both plywood panels as well there will be a uh set of casters down at the bottom and of course an integrated switch As I said the legs will be made out of 2x4s and I thought that I had some 2x4s on hand just some scrap pieces laying around and as it turns out I do not which is kind of odd so I do also have some 2x10 so I'm basically just cutting 2x4s out of 2x10 this will actually allow me to get a little bit better material which really isn't that necessary for this project I'm making all of the rabbits on the legs by making two 90° cuts on the table saw and while they're not symmetrical legs there's going to be two lefts and two rights I can get away with cutting every one of them the same and then taking two of the boards and flipping them into the end uh which reverses the cuts and then that will result in two left and two right [Music] legs I'm using scrap plywood for the lower four panels and these need to be about 11 in tall and about 1 E of an inch longer than the filters are [Music] [Music] [Music] the blower is just going to sit on the floor in the middle of the cart and it's going to be attached to one of these panels now in order to attach it to the panels I've attached some scrap pieces of wood to the blower itself and then I can screw through the panel into those pieces of scrap wood now I've already taken the time to Center everything and lay out the appropriate size opening for this particular blower and now I just need to cut this out with a jigsaw [Music] the assembly starts with the front and the back and I'm using one clamp to hold everything together and with very little pressure I don't want the legs to Bow up as I'm trying to screw the plywood down now each piece of plywood is going to be secured with four screws per side and I am pre drilling these holes because uh the solid wood beneath the plywood is rather thin and if I put all of these screws along uh a grain line on a very thin piece of wood odds are it's just going to pop that piece off and split right down the middle so I don't want that to happen I am pre-drilling the holes now once the front and backs are completed then I can attach those together uh with the exact same method using the plywood panels which are also the exact same size for the sides when it's attaching the side panels though I do not need to pre-drill because I am going through a much thicker piece of wood at this Direction with the main structure completed I can use the outside corner measurements to determine the final dimensions of the top and bottom plywood panels and again I'm using some more scrap half2 in plywood for this [Music] I'm about to install the motor in here but I wanted to point out that these butt joint seams down here I just put some really strong duct tape and I don't think there will ever be a problem with air seeping through here because there is so much filtered air uh air through the filters up here at the top um but it's it's really simple to just put some tape down there and seal that off and prevent any issues long term now when the filters are installed the sides will be lined up with those rabits so there's no way for the filter to be pushed through on the sides however I don't currently have anything on the top or the bottom so to add some support down here at the bottom I'm probably going to use some more scraps of/ in plywood and just put a little band on the back side of this piece uh that will secure the bottom and prevent it from being pushed forward now the the top side I don't really have much to attach to other than this top panel so it sounds like a good opportunity to use the offcuts that were actually the waste material from when I cut the rabbits so I'll just size these to fit and attach them to the bottom of the top panel I went ahead and did the electrical really quick and it's just a very simple process so I'm not going to cover it in this video there's tons of resources that are better suited to show you uh how electricity works and and how to wire up a simple setup like this so I'm not not going to show you all the details however I will give you a quick rundown this is my power coming in and this is a very tight fitting hole however I do not want this to be pulled out and potentially disconnected from the motor so on the inside I put a couple zip ties and from on the inside here uh the power wire is split and a new wire comes up to this switch two wires and once the switch is activated power comes back down the other wire and Powers the motor now I'm pleasantly surprised at how quiet this actual blower motor is so now all that's left for me to do is to uh steal the casters off of the other cart and then uh put the planer on top of it this is pretty much done [Music] I made some 5mm hardwood plywood clips and these are held in place with just one screw each and they just swivel into place to hold the filters in place now I don't have a set of plans for this because I built it specifically for my use with the motor that I had on hand the blower motor uh but if you are interested I do have a link to the SketchUp file I used in the article for this particular video thanks for watching and you guys have a great day oh [Music]
