Designing & Building A Segmented Feature Ring

one of my favorite parts of woodturning is segmented turning and one of the things I like best about it is trying to design a unique original featuring a little difficult to do there are thousands if not hundreds of thousands of terms out there doing segmented turning so coming up with something unique probably not going to happen but anyway I've come up with this right now I've got diagonal slices going two different directions separated by a vertical piece and then carrying on around the bowl now I want to make each of these pieces that are in the diagonals 3/16 of an inch thick so the first thing I need to do is come up with some strips that I can cut into these diagonals let's take a look at that first I have my strips of wood cutting out I put them through the drum sander to make sure they're nice and smooth ready to go there right at 3/16 of an inch I need four strips of dark wood and three strips of light wood for each of the blocks that I'm going to make now I've got walnut for the dark wood birch for the light wood some of the walnut had a severe knot in it so I've made sure that each of those pieces is stacked together I'm going to have to cut that out it's going to be scrapped I don't want to have to use scrap on both pieces I'll just lose more that way so now I'm going to glue these together and I'll be right back now I will use the jointer to clean up one edge the other edge is cleaned up with the table saw well I've got my strips glued together now I think they look alright not too bad anyway now I'm going to do a little figuring writer exactly how I'm going to go about cutting these then I'm going to come back and show you in just a moment I've cut one of the rectangles from the drawing that I made and is not to scale these strips are slightly wider than the ones on the paper that was done intentionally I wasn't trying to make it to scale anyway if I take and make a 45 degree angle from this side across to the center of the center strip I'll end up with a square and I don't want a square you may be able to tell that this dimension is slightly greater than this dimension so to do that I want to come from the junction on the end of the walnut and the birch right on that corner and draw a 45-degree line right there now I want to draw a 90 degree line off of this one which is the same as drawing 45 degrees from this side in this way not sure if the cameras going to pick this up I've probably got everything in the way now another 45-degree line from that corner right here and one joining back up to that point and that gives me the rectangle which is inside here now what I want to do is go along and draw another one and I want to start this one from down here instead of up on this face so I'm going to crop come across here a good quarter of an inch so I have space between the two lines to cut this out probably on the bandsaw now I'm going to use the junction that this line has on this walnut and this birch and draw 90 degrees from that line which is 45 from this face and 45 degrees from this corner now I'll come up to this point right here from this face and that gives me another rectangle right there now if you take a look at this if I line this one up with this rectangle you can see that this little triangular area matches up with what this is and if you can visualize this being sanded smooth and this being cut so that this side matches that it will have to kind of swing around you'll see that this little triangle area will match up just the way this one does and then there will be a little strip put between them a little spacer so that's my next step is to cut these apart I'm going to first go along and draw a whole bunch more of these rectangles and then I'll be back to show you my next step my fingers are just as precious to me as I'm sure yours are to you so when I cut small pieces on the bandsaw I like to use a hand screw or some other method to hold them rather than using my fingers well I used the bandsaw got all these pieces cut now I'm going to take them to the disc sander and straighten them up square them up get them to the dimensions that I want I've got the disc sander table so that it's Square to the disc and I put a fence on also running Square to the disc in the other direction so I'm going to first put this piece with a long dimension against the disc and sand it just by eye very carefully to get it straight along the line that I've drawn then I'm going to put that side against the fence and run it up against the disc until I'm up to there at that point I will use an adjustment to make sure that I get the same thickness in both directions on all the pieces but instead of try and explain the whole thing why don't we just go take a look I'll show you what I'm going to do now I intend to take this against the disc until it's right up to that line then I'll put that now flat square edge against the fence and drive it up against the disc until I hit that line I have an adjustable piece here there's an adjustment but I've loosened this this piece will slide up and down I've adjusted it so that now when this piece hits the edge of this sled it will always give me the same size I will put one of these pieces against there and drive it up against the moving sanding disc until it stops when I've completed all of these in this dimension I'll be able to turn it this way and have the same distance for this one so I'm going to do all of them in this dimension then I will turn them readjust it and do it this way let's take a look at a couple of these now with all the pieces sanded and put in the position they're going to be in you can see the design and I've cut some small pieces of walnut to fit in between them so I'm going to glue these up in pairs now I'll glue up these two with the walnuts trip in between them and the next two again with walnut in between them then I will finish cutting them to the angles I need and glue them up later I will show you the step by step as I go along so now I'm going to glue all these pairs up and I'll be back I have the pieces glued together with that chunk of walnut in between and now I want to make sure that one side is perfectly flat to do that I'm using 150 grit sandpaper that's glued on to a sheet of quarter-inch glass it's very flat to make sure this is flat I'll just draw some light lines run it across the sandpaper once those lines are gone I'll know it's really slashed and it's all ready to go so I'll do the same thing with all the rest of them and then I'll be back for the next step I have this side nice and flat now I know that the disk is Square to this fence and I know that these two sides are parallel so if I run this side against the fence and butt it up against the running disc I'll be able to get a square corner here I've drawn lines and I'm going to just touch this up until they just disappear that's the step I'm going to take now now we'll continue that process with all of the other pieces and then I'll be back I'm going to go back to this push stick I've got the stop set I'm going to put this piece in here push it up until the stop hits the side of the sled and that should be right let's give it a test and see how this works just have a little bit of lines there I'm just going to reset this stop and then give it another try and that's looking real good I'm just going to do all the rest of them and I'll be back again now I will use the disk sander to do the same thing on this face because I want this face and this one to be perfectly parallel and again I need to adjust this stop just a little bit and give it another try and after a couple more adjustments I've got those faces nice and parallel now I'll do the rest of the pieces all right the standing is finished each of these is going to be one of the segments in a 16 segment ring now I have to take this over the table saw use the wedgie slit to make the angles and if this is the front the outside I'm going to put an angle here and here on each one of them let's lower the table saw and take a look at how that's done now what you're looking at here is the wedgie sled I'm not going to go into a lot of detail on this I'm going to put a link in the description box below the video so you can look up Geri Bennett's channel he designed this I think it's wonderful it sure saves a lot of time making the segments but better that he'd explain the whole thing the short version is I've marked a line on what I want to be the exterior of the bowl segment I'm going to put it against this side of the fence put it up against the stop block and I have it set so that it will cut right on the corner then I'm going to use this just to hold it in place so it doesn't move when I push it through the blade so I'll do a few of these then I'm going to take them turn them around put them on this run up against the fence and take the other side of the segment off now my next step is to take the segment that's being cut here flip it around put against the stuff on this side hold it again and push it through the blade cutting this angle well that went really well that wedgie spread is awesome Thank You Jerry Bennett wherever you are for designing that and letting us have the plans it's awesome there's no light at all through any of these between the segments so I will happen with this I'm going to glue it up and help them right not to show you what it looks like while there they are is it perfect no Gord nothing's ever perfect it's 12 and 1/2 inches in diameter 3/4 of an inch thick and I'm quite pleased with it I think it's going to look good once I put into the same kind of journey for some kind I set out to figure out what I'm going to put it into a vessel a bowl I don't know yet but that's what today was about just showing you how I put this ring together I hope you enjoyed that to give you some ideas on what to do designing one of your own thank you for joining me I hope you had a good time I know I did enjoy your day have a good time in your shop and be safe don't forget to subscribe if you haven't done that click the like button if you enjoyed this thanks for stopping
