hello people of the Internet welcome back to another video today I'm going to be making the jigs which are necessary to create a Kumiko asano hop pattern along with the pattern itself so you'll need a couple different jig angles for this pattern a 45 that's only 2.5 and a 67.5 now I've already made and used these jigs this voiceover comes with the quote unquote lessons learned after making these the asano her pattern is essentially made from three components the orange diagonal piece which has a 45 degree angle on both faces of each end the two green components which have on one end a 22.5 on both faces and on the other end a 45 on one face 67.5 on the other finally the blue component which has on one and both faces at 45 degrees and on the other end both faces at 67.5 degrees the blue component locks in the entire pattern so it's crucial that it fits really well first thing you need to do is get some wood for the jigs no it doesn't have to be any particular dimension just something which you can clamp in your vise and provide enough support for the plane which will run against the face the 45 and the 67 point five degree cuts are easy to achieve on a miter saw you set your blade to 45 and 22.5 respectively the difficult one is the 22.5 know the way I solved this was to cut a piece of plywood at 45 degrees then clamp that to the table of the miter saw set the blade at 22.5 degrees put your wood parallel to the 45-degree edge of the plywood and that should results in a cut angle of 22.5 degrees now I chose some old pine which I had laying around to make these ideally if you want to use them often or make many of these patterns you should choose a hardwood because the plainer the chisel however you decide to use them will tear up the soft pine jigs pretty fast concerning the dimensions I found if they're using them that only one dimension is really critical to this and that's the width of the dado which runs through the middle of the jig the width of the dado should equal the depth of the Kumiko which you want to make the problem that you get with a dado that's a little bit bigger than the pieces of wood which you're cutting is they they're difficult to hold flat against the let's call it the reference face of the jig so it's always going to want to to kind of cantilever as you're planing or chiseling threads so of course you need to make your jig long enough also to fit the largest piece of what you'll be cutting all of the other dimensions so the the height the width the depth of the dado etc are all basically unconstrained and you can make them how you want the one point I've changed since this was filmed was the length of the blocking piece in the jig the reason being was mine were far too short to accommodate all the sizes of the wood that I would need to use in the jig and this little clip you see what I mean the green component should be able to block up very shorts and also a very long piece of wood in order to attach the blocking pieces to the jigs I drilled and tapped the hole through the bottom of the jig then I screwed in a fully threaded m4 screw and got a knurled thumb screw with a washer to hold the blocking paste of the jig this worked quite well if I did it again I would maybe go with an m5 screw and a bigger thumb screw or even a wing nut the problem is after using these for several hours and adjusting them constantly your thumb gets a little bit sore from the from the small screw so some people create a fourth jig which allows you to thickness plane the components since I have a bandsaw on a planer thicknesser rather than doing it by hand I just stuck with the power tools if you have for example a drum sander you can also make these components and a drum sander instead of a planer thickness or the blades in my plane are quite sharp so it leaves a really nice finish I don't need to do any sanding or anything afterwards granted that you feed the wood in the correct direction so not get any tar out so after your components are all rough cut you can start to cut the angles and the ends according to the drawing which I showed at the beginning there was a lot of this I left most of it out of the video so you can use these jigs with either a planer chisel whichever it's more comfortable for you now the plane you see me using isn't the ideal plane for this rather you would want a low angle block plane whichever plane you choose it should also be sharp which mine isn't it's not dull but it's not great however you see that it works anyway so it's you don't have to have perfect tools for this I found the best technique for me was to rough it down with the plane and to do the final few passes with the chisel I guess if you had a really sharp plane you can do it all the way down with the plane you can see I'm using my table-saw crosscut sled with a stop block clamp to it to cut the small components to length so I didn't have to plane so much in the jigs then there's one final shot of the 67.5 degree jig and you can see in the background the Kumiko is starting to come together [Music] for the finish I used oil on the cherry with a little bit of red pigment in it to make the cherry pop a little bit more and on the maple I used beeswax if you're going to be doing the finishing like I did so prior to the piece being fully assembled make sure you don't apply finish where there's going to be glue otherwise your glue won't stick for the finish I went around the whole piece and put a tiny dab of glue it each in her face and then slid all the pieces together and I used really the minimal amount of glue so there wasn't too much squeeze out and I didn't have to do too much cleanup outdoors so if you haven't fallen asleep by this point yet here's some nice calm piano music and another couple minutes of me painting and assembling this thanks a lot for sticking around if you've gotten this far this was actually a really cool project I enjoyed it a lot I think there's going to be a second video about this possibly where I make a second one of these a little bit smaller and in a box but let's see all right thanks a lot for watching and catch you guys on excellent [Music] if you're looking for some activities to meditate to forget all those apps man you can just build these things all day this took me probably the better part of an hour to individually finish and assemble all of these pieces it's was really nice actually [Music] [Music]
