Wedgie/ Miter Sled (Free Templates)

I'm a little late on this topic but now I'm also going to make a wedgie slit for the segments of rings for segmented woodturning for example like this all of you one of the big challenges in making something like this is to cut the segmented rings and the difficulty there is to cut the angle here between the joint surfaces exactly right most often that will happen that there's the gap like here or here and that will show in the final Bowl and you definitely don't want that they of course are some workarounds to avoid these gaps but they're mostly time-consuming and well then you have to do two blowouts for just one ring but with a wedgie slides you can cut these perfectly every time and for the which is that I want to build I change design slightly so that can also double function as I might have lit and you can use it for something like picture frames or well mainly picture frames as well the base of the sled is a piece of MDF which conveniently appears at the exact right moment on my table saw with the correct dimensions cool next I need to cut the slots into the base and because I'm lazy or well it's convenient for me I'm using my CNC for that but it's also really simple to do this with other CNC with just rudder and a circle jig you can find a link to the original building plan from Jerry Bennett in the video description rotting into MDF always leaves a burr on the edge which is very simple to remove with a knife and our carriage bolts can right around these slots unfortunately a round router bit doesn't cut square time for a fire next kind of fences which usually are also made out of MDF but something much more substantial would be polyethylene I got this piece from a factory as a waste piece for free as well this is I think perfect for this job I trimmed one edge straight and then cut into the biggest size possible now somehow nobody really mentioned this yet but for this jig it's extremely critical that these fences are perfectly parallel to each other so after you've cut them you should measure both ends and compare them it seems like that I'm about 1/10 of a millimeter off this one this one is pretty good actually it's perfect this one's a really shallow trim cut now it's perfect then I control the first mounting holes and rolling into polyethylene is so cool that's like butter and leaves the night shavings to locate the other hole position I just have assemble a jig like so and with a bread condiment I can put this in the slot and then scratch onto the fence and that leaves a tiny scratch on the fence I'm also tempering the edges because they are really sharp now you can see it assembled and working and this is what it looks like from behind to make it nice and comfortable to tighten the nuts I made a few knobs now just have to insert the remaining nuts you can also find a cutting template for knobs like these in the description one important thing about these knobs is that they are smaller than the fences right so that when you're working with stock higher than the fences they can't interfere next I need to make the Guide bar for the T track slots and since I have it I'm again using polyethylene almost perfect just need to remove a little bit in the middle now this is a pretty decent fit and it doesn't slide which is good because of my sliding table as it's not super critical how Square this chick is to the blade I just buttered up against a fence and I set the fence so it slightly overhangs two saw kerf now I can mark with a guide by is supposed to be attached this one I need to tighten by the hand now I can drop it into the slot and then line it up with the fence again now I can't slide it out of the slots and screw down the other and now I can jump cut it and make it zero clearance with the blade as the - lets this chick would be already finished and together you will just open both dentists and then put something square in it like so then tighten it make sure that the square is absolutely no play in here so and that means that from here to here it's square and from here to here it's square and as an example I have 2 pieces of scrap wood when you work with stock that fits in between here you can use the inside surfaces but otherwise just use the outside surfaces it's important to use one fence for one piece and get offense for the other piece and this joint will be s square as the reference square is and in this case it's perfect and this is the whole principle of this G you could also say that with this setup you make rinks with four segments and as they are square they tend to be pretty practical for picture frames and when I set a jig up with this part of the square which is 45 degrees I get a ring with eight segments so all you really need is something that represents the perfect angle with which you can set the jig up but the problem there is where to get these why don't you would be to buy them the guy who came up with this sells these so-called wedges that's also why this is called the wedgie slits on his websites and I leave a link to that in the description you could also cut them out yourself with the CNC but as probably most people won't have access to one I came up with another solution basically we are making an adjustable one of these this is the template for it and if you're interested in making one yourself you can find a link in description where you can download it for free with this template you can make a wedgie for literally any number of segments you would like I already drew lines for the most common segments numbers and now let's say we want to make a wedgie for 18 segments that means we follow this line here brings us here it means we have to cut the rough shape out here this line needs to be cut out exactly all you need is a piece of plywood with one straight edge and you will line it up with the edge of the template when cutting it out you don't need to be super precise because it gets fine-tuned anyways for again punched a hole location before cutting it out it should also be cut out relatively exactly and send it to the line you will also need another small strip of plywood with one straight edge I need to make the pivoting piece above parallel with the cut line then take the CEM leave us so the handle faces up and screw it down screw it down quite firmly so that it sits pretty tight but you can still move it by hand and with this cam liver you can now precisely adjust the angle so now to use it in five units put the camera back into the middle position and set the jig up with it here you can also see how to use Jake you always were friends off of one edge of your stock and switch between the fences as shown there's no need of flipping the piece around so one big source of angle arrows got eliminated I send it off all the little bursts and I can put it together touring and see if there are any gaps now as you can see the angles are not perfect and there are gaps they are on the inside and that tells me that the angle of the seconds is too big or too steep so now I need to adjust the wedgie a little bit may by this amount and make another test ring if the gap would be on the outside then you just adjust in the other direction all right on the fourth attempt I finally got it right and now I know that this wedgie is perfectly set up for 18 segments to make sure that will stay perfect you could either screw it down but I would prefer to Gulu it down kind of lift it up and turn it back into position when you shift the contact surfaces of spring clamps like so then it will also apply a little bit of forward pressure so it presses against a cam and that's what we want here now you can even remove the cam river and use it for the next one one problem you might have already seen is that when you cut a segment it always falls right next to the blade which is not really safe what most people do to a widest problem is to make 0 crowns insert which has a little rent next to the blade so the segment's fall down this ramp and are then away from the blade and can never touch it again and I think I'm going to do exactly the same except not a whole insert because that's kind of tricky for my table saw but instead just a piece that I can attach to the insert I secure the RAM firmly so I can plunge cut through it now oil room is finished and as you can see it has various pins in it which hold it securing in the answer and they are all there for a good reason and the Baptist's all teeth are spinning upwards and if for whatever reason they would catch on the ramp they would roll upwards and towards me which would be terribly unsafe so to prevent that I installed this angled pin and it hooks into the insert plates and holds it securely in the front the stop you spin down so no issue there but they also spend forwards and if they catch the ramp they could also shoot it towards me so to prevent that just the second pin and the magnets and they hold it securely and as you can see it's really simple and quick install safety operation and you don't even have to remove the ready knife so no excuse for not using it lastly I change the shape of one fence to make room for wider stock I also painted and varnished it a little bit to protect the NDF and also drew a little reference scale on here so that when I set the jig up I said both fences up by roughly the same amount and also made a convenient storage place for it right on the lake and so now I'm prepared for the next segment returning project and till then I'm a little late on this topic but now I'm also going to make a wedgie slit four segments or crap you could also cut them with a CNC but and I also made a convenient storage place for it's right on the lathe cabinet which doesn't look that what yep
