Table Saw Bowl Making Jig - Simple & Free Plans

do you have to make a gift for someone very fast i do do you have too much scrap wood laying around your shop so much do you love bowls i really do do you not own a lathe but own a table saw yep well i've got the thing for you introducing the all new table saw bowl making jig stay tuned for details [Music] the first thing i'm going to do is cut out all the individual pieces for this project out of this three quarter inch plywood material now we don't need this entire sheet of plywood as you can see from my cut list here it only requires about a two foot by four foot section of plywood the rest of this can be saved for future projects this cut list can be downloaded for free as well as all my other plans from my website diybuilds.ca so let's go ahead get these pieces cut out and i'll meet you back here once that's done [Music] so you can see i have a long piece of half inch threaded rod and i need to cut it down to eight inches for the vertical piece that holds onto the bowl and then two four inch pieces for either side for mounting the swivel piece on top so i'll mark this and cut it so the last piece to cut out is the cross member that holds the bowl that swivels back and forth and i call it a two by four piece material this is a two by ten piece material which i do have i don't have any two by fours kicking around so i'm just going to cut this to length and then over at the table saw cut it to the same width as a two by four which is three and a half inches actually one thing i did forget is that i needed some runners for underneath of the jig to keep them locked in the miter slots on the table saw i just happen to have these strips of oak which perfectly fit into these slots so i'm just going to cut them down to final length and these are going to be our runners for underneath these will be perfect so in front of me i have all the pieces we need to build this jig now we're not quite there yet as there's a little bit of fitting to do some holes need to be drilled and so on let's just go through all the parts so far we have the two runners which will go underneath the base plate and they will lock into the miter slots on the table saw these two pieces will go around the back side and hook onto the rail of the fence to make it more secure this is going to be a rigidly mounted piece that goes between the two uprights to kind of keep some rigidity in there as well as acting as a stop for this piece to smack up against so it can't go more than 90 degrees this is the rotating part which is going to have a bolt going through it to hold the bowl and to spin so there will be two bearings mounted in here and these are our four braces which are going to go along the uprights on either side just to give a little more rigidity the next thing i want to work on is these two upright pieces so i'm going to mark out exactly where these r8 2rs bearings are going to go into each side and to do that i'm going to be using this inch and an 8 forstner bit and recessing a hole to make these flush and this does create a very nice press fit so these won't go anywhere especially combined with the bolt and the lock nuts holding everything in place afterwards so let's head over to the drill press drill these holes [Music] next i want to cut out the circle from the base here and the reason for this circle is a to make room for the blade and b that circle is going to hold the bowl in place when we flip it upside down once we've carved the outside we want to do the inside of the bowl we have to flip it upside down has to sit inside that circle as we raise the blade and it spins and carves out the center so i have marked out right now my distance to the center of the blade here and the center of the jig here and i've marked a hole now i thought about marking a circle here and just using my jigsaw but i don't think that's going to be precise enough so i'm going to have to whip together some kind of quick circle cutting jig for my router and i'll meet you back here and we'll cut this circle out perfectly so we've got this screwed down at our center point of our radius and i'm just going to move this around lowering the bit a quarter inch at a time and that'll have our circle totally cut out [Music] now that the circle's cut out i have the base piece clamped up in my linear actuator vise and we have this piece which is going to hang over the back side on the bottom this is the bottom this is the top and this is going to be used for referencing against the back of the table saw and make lining up the jig a lot easier so i'm just going to keep this in place with some brad nails and then fully attach it with a bunch of two inch screws so before i attach this piece of the bottom which is going to hook around the back side of the fence and lock everything in place i want to get the miter runners attached to the bottom first so first i'm going to lay down some spacers here these are quarter inch hardboard and then these strips are about eighth of an inch it doesn't have to be full depth at the miter gauge it can be it's not going to matter and i'm going to lay this down here with that back edge resting against the fence now i've already measured out the exact center of my circle which i know is 12 inches so it's very easy to reference off the side here instead of trying to refine the center of the circle again and i've already set my fence to that exact position so that's going to help me when i go to lay these strips down put the glue and then place this down this fence is going to ensure i don't have to think about it at all just slap it down put some weight on it and let the glue dry so let's go ahead and do that now okay so these two strips are fully glued on and they ain't going anywhere but i do want to add a couple screws for some insurance so my little helper here is going to help me drill four holes one two three and go ahead you gotta squeeze it good job and then we're going to countersink it so i think i got to do this i got to push pretty hard do you know how to use the screwdriver yeah okay you want to try let's see let me just get it started for you so we always spin this way right and grab it up here you can use two hands and you got to push down when you're spinning so that's the slow way do you want to use the drill good job one thing i've learned if you're going to let the kids use the drill to drill things in you got to put the clutch on otherwise they're going right through china perfect mister good job you're a great helper okay so the next step is to attach this piece right here and that's gonna hook onto the back side of the fence and really lock in the back end of the whole jig so now that the back is secured on the front i want to use these big toggle clamps to keep it tied down to the table and to stop it from sliding back at all i want to cut some grooves into the top here that will allow these to sink a little bit into the top that way the back here is touching the table saw and with it being locked into a groove it can't move at all and we're getting it totally fixed down to the table so it's not floating in any way at the front so i'm just going to mark around these toggle clamps and then i'll use a forstner bit to make a hole and then i'll actually move the pole up about a millimeter that way there's some pull back on it and it's kind of acting as a spring so next i want to get these two upright pieces permanently mounted to the jig and to do that i've marked the center of my circle and the center of where this bearing is and i'll just line them up like this now to get my spacing where this needs to go left and right i figured out with my hard spacer block which is going to be located at the top but i'm using it at the bottom to calculate and set my combination square at the appropriate distance here so i'll just line it up like this and then attach it with a bunch of screws now in order to make this easier i'm going to drill two pocket holes right here at my homemade pocket hole machine in just a second and that'll allow me to line everything from the top before coming back drilling holes on the bottom and driving a bunch of two inch screws from the bottom to totally make this secure so [Music] the next thing to do on this swing arm is to drill the recess on the top and bottom for both bearings so i've got marked my center here as 6 and 11 16 so i'll mark both sides center punch drill the forstner bit on both sides and then i'll drew a through hole which is i don't know half inch or even slightly bigger all the way through just to make room for the spinning bolt inside of the swingarm so this bolt is going to go through here this end is going to get attached to the bolt this end's going to attach to the drill and because of that i'm going to head over to the belt grinder and grind a triangular shape into the top of this so the chuck can better grip onto the top of it that came out pretty nice the drill should have a good grip on this now our next step is to press in these bearings which shouldn't be too hard nice snug fit there so we can run our bolt through here now spins nice and good so now i'm gonna put just our nyloc nuts on either side [Music] so that worked great i just need to shift these down a little bit because this one didn't spin so much and this one did so i'll just fix that so now it's time to mount the swing arm to the jig itself and you see i have clamped on top two pieces of wood and that's just so everything sits flush along this top edge now to align everything left and right i have marked here exactly where this needs to sit on both sides because i used a square earlier and just made sure everything aligned then i'm going to clamp everything in place so nothing moves around on us and then i'm going to use this 13 32nd brad point bit and drill all the way straight into that 2x4 to make room for our bolt the reason it's 1332nd is it's just undersized enough that the threads are sticking out and going to have enough bite force into the 2x4 then we'll come back enlarge this hole insert our bearing and then we'll drive our bolts in to the 2x4 and then put our lock nut on the outside and everything will be nice and secure [Music] so you see i just ran my half inch tap in both sides here only a little bit of the way i want it to really grab once it gets further in so we won't tap the whole hole so now i'm installing the nylock nuts onto the end of these bolts so i'm just grabbing them it doesn't really matter if i mess up the threads too bad and i'm just going to tighten them on here now in order to install these you need to put a jam nut on the end otherwise the nylock is going to spin all the way down once this really starts to grab into the two by four and that's no bueno so just put a jam nut on the end take it off when you're done so i've got both bolts here just put the washers in and now we're going to slide this guy in here you really don't want this too loose you want a bit of friction in there and now you ask yourself well why did he use bearings well because i needed two here and it came in a pack of 10 so whatever now we're ready for the last few finishing touches i'm going to go ahead and install these cross braces all four of them two on this side two on the other with just some glue and brad nails into each end and let that set overnight then i'm going to be installing this cross beam right here this really strengthens up the top but it also acts as a stop so when this piece pivots it can only go this far 90 degrees or this far 90 degrees i didn't want it being able to go this direction we're always going to be working backwards with it so this will get installed with just a few screws or one screw in each end and that's it okay so what i've got here is a big old chunk of wood i spared you guys the experience of me cutting everything up and gluing it all together this is basically just a bunch of pallet wood there's some maple on the bottom and some oak on the top i figured it would be nice to have the oak as a rim on the bowl so that's what i did anyways so now i've got to mark the center of my bowl and i'm just going to go like this across and that's roughly the center next i will make a center punch hole and then i'm going to put my pencil in the end and i'm just going to draw my circle this is my makeshift protractor it's just spaced at five and a half inches between these two circles and the reason for that is the blank i need for carving out the bowl on this jig is an 11 inch diameter circle that's three and a half inches thick and that's going to be the same for all the bowls i need what i'm going to do is go over to the band saw and just cut out this exact circle then from there over at the drill press i'm going to drill my 3 8 inch hole down two and a half inches and that will allow us to mount it up onto the jig from there it's turning this into a bowl so as it turns out my drill press is a little bit too small so i just drilled a hole in this block with the drill press so i know it's perfectly perpendicular to the surface so i'll go ahead and drill this hole [Music] [Music] [Music] okay let's just lower the blade real quick that worked remarkably well i mean there is this uh chip out and fuzzy stuff on top that might just be because it's red oak that might be because it's end grain and that was gonna happen on any species of wood i'm not sure but it's nothing a little bit of sanding is not going to clean up before we flip it over and do the other side so let's spin this like this and get it taken off okay see it's still got the flat bottom there so it can actually be a bowl when it's done so let's get this top bit cleaned up oh this actually turned out super well i'm pretty impressed it is a bit rough though so i'm going to go ahead and use my random orbit sander as i'm spinning this just to smooth the outside work my way through the grits [Music] wow that came out really nice this thing is wicked smooth and even has a bit of a shine to it so i'm going to take this off and i'm going to show you how i'm going to be mounting this upside down to carve out the inside i'm going to take the bowl i'm going to slide it inside of the circle here i'm going to use this piece which i've drilled an appropriate sized hole to be threaded onto this shaft and this piece is going to get hot glued onto the bottom of the bowl as a temporary connection that way it couples the drill to the bottom of the bowl and during the hot gluing i'm going to be spinning it slowly as this auto centers itself and grips onto the bowl that's the theory at least now in order to do that there's not really any clearance here so i'm just going to lift up the clamps in the front and lift up the jig and slide the sucker on first remember that time i forgot to trim away the extra runners that go in the miter slots well that's now holding the bowl so give me a second and i'll remove those guys and this will work for us [Applause] okay the runners are out of the way so let's plop the bowl down in here and now we'll tilt this over attach our drill again [Music] and we'll just lift this up so it can fit over now let's get some hot glue in there and spin her up you know that feeling when your plan doesn't work okay so i think we're good now so what i ended up doing was putting more hot glue underneath of it again leaving the front clamps off and just spinning this by hand really slowly and this part right here just trying to get it centered and it just kind of auto centered itself and after a few seconds 10 seconds or so this was solid enough of a connection to where now we can spin it from up here so let's get our drill attached turn the dust collection on start raising the blade as we spin this and that will carve out the inside for us [Music] [Music] okay that should be it other than a little bit of sanding on the inside this should be a bowl let's check it out well guys i don't think that came out half bad especially the outside where i was able to sand it this inside though i think this is just going to be left up to hand sanding which is a bit unfortunate but that's the price you pay for making a bowl on your table saw anyways let's get this sanded up put a little finish on it and see how it looks oh yeah we got to get this guy off too i'm going to try just drilling this straight in and see if it pops off if not we're going to have to chisel it nope we're gonna have to chisel that guy off oh well so in order to take care of this i decided to do what any rational person with the cnc would do and just freehand it let's see how this goes so you can see i got the glue off the bottom so the next thing i'm going to do is try to put a quarter inch round over on the outside of the bowl and it's not going to ride up against the bearing it's going to ride up against these two points in the fence because if it was to hit the bearing it would be kind of a over round over like because of this angle it would dig in too much so we're going to see how this goes hopefully it's good well guys there it is after a marathon of sanding she is finished for being made out of some scrap pallet wood maple and red oak i think it turned out pretty nice so now i'm just going to put on some mineral oil to finish it and this project's complete [Music] do [Music] don't act like you're not impressed [Music] you

Why not just leave the bowl hot glued in the jig, tilt it up, and then spin it with the drill while you sand the inside?

[u/staser9er]

How safe is it having the forces of the spinning bowl and rotating saw blade interacting? Will this damage the saw blade? It seems like the blade is not only striking the bowl while it rotates but the bowl is striking the blade from the side while it spins.

Man, this looks like a good way to end up explaining weird shit to a paramedic.

[u/OozeNAahz]

He…or the OP…have a very liberal use of the word “only”

A mitre saw, a drill, a belt sander, an orbital sander, a jigsaw, hot glue gun, a router, and a CNC machine all fit in that little word “only”.

[u/Vast_Ad9484]

This guyis fuxking crazy. I liked the bit where hes hammering a chisel towards his abdomen. Absolute idiot.

[u/Gfilter]

Some people trust their table saw too much, and then there’s this guy.

[u/chance--]

Using pallet wood for a bowl is a new low.

Folks, you have no idea what that pallet held or what was doused on it. Plants on pallets, for example, get hosed down with all sorts of chemicals.
