Lyre Harp Build – Episode A – By Dell Rosa

in today's video we will begin the woodwork on the liar harp to get started I have some hickory planks that I will cut to length with four pieces all cut I Mark out on the wood the shape of the arm with my stencil notice I have room for the arm and both upper and lower Bridges knowing where the cuts will be made I marked for screw holes to add screws to hold all the pieces together screw holes are pre-drilled to make adding such long screws easier and not split the wood screw is a sufficient length are added to hold all four pieces of wood together as a single block with the block secured it's time to start our first cut [Music] we're using a large bandsaw with a heavy wood blade to cut out the first section of wood [Music] this large section of wood will be used later to make our Bridge pieces strong more room to maneuver we will cut closer to the curved shape of the arm pre-cross cuts are made to avoid putting too much stress on the blade while cutting the Curve here's the shape after this first round cutting [Music] now to work on the outside curve cutting the outer curve is taking shape we are certain to leave extra wood for later shaping [Music] we will leave some wood near the top of the arm so the screw can remain and help and help hold all four arm pieces together for shaping on the sander most of the sawing is now done for the arm pieces now we will work on cutting out the lower Bridge pieces again extra wood is left on the ends to hold the screws notice we only need two pieces of wood this time more cuts are made to carefully shape the inside curves with most of the saw cuts done we move on to refinements of the shape on the Belt Sander we are using a very coarse 80 grit paper to avoid burning the wood we have roughly defined four arm pieces and two each of each Bridge piece now we can refine the inside curves using a spindle sander okay these are cleaning up nicely and looking a lot more like the final shapes shapes Bridge pieces are going to have tenons so I can glue them together now I apply West system epoxy to both faces and then glue them together they are held with both screws and clamps while curing later after curing the excess wood which was retained for the screws can be trimmed off removing the excess allows me to better judge where the Tenon needs to be made [Music] with that we are ready to start making the joints I first try to clearly Mark the ends of the arms where the lap joint will be formed then I trim each arm to the correct length first with the bandsaw and Leader by sanding I cut the Inside Edge of the lab joint by hand foreign next I removed the extra wood with a chisel be careful to support the wood while chiseling as the grain runs such that this is very easy to break oops I broke one but fortunately only one I'll be sure this ends up in the middle somewhere I repair this piece with some quick 10-minute epoxy so I can keep going here's a close-up view of the lap joint after all pieces have been cut and shaped now let us work on preparing the lower Bridge first I Mark out where the notches need to go arms to hold the bridge I'm using my drawing to align the pieces correctly as I go I have also marked the arm edges on the bridge piece next I will cut the bridge piece by hand to start creating the Tenon I remove the bulk one with a chisel like before [Music] careful not to overshoot with the Chisel I try to do my refinements by chiseling in a direction that is safe and not likely to break good wood I can use a coarse rasp for removing wood quickly as I get closer to the final dimensions let's work on preparing the lower Bridge mortise I will double check my joint location and verify the desired depth of the notch I chiseled out the mortise Notch by hand with the pieces heavily secured to the workbench [Music] cut I make several dry fits to refine both the Notch and the Tenon [Music] I will make a similar notch on the other half of the arm both notches will come together to form the mortise with both notches available I again make a dry fit to be sure it is coming together correctly the same process is used to form the mortise and Tenon for the Upper Bridge as well something I realized later is that the bottom Bridge joins end up hidden and so can be a bit looser this allows me to make the Upper Bridge joins tighter as they will be visible in the finished product now with all the notches and tendons ready I dry fit the entire unit together to see how it fits this stage is looking pretty good [Music] next we prepare a support board for our eventual glue up this board will hold all the pieces together and flat while the glue sets up marking a piece of one centimeter thick plywood with a pencil the rough shape is cut out on the bandsaw [Music] there is no need to cut any interior holes [Music] the board is covered in packing tape to prevent glue from sticking to it later on I took the time and trouble to refine the mortise and Tenon joints further with some carving knives and sandpaper [Music] this allowed me to tighten up these joints further [Music] further dry fits show that the joints have improved prepare all of these pieces for glue up the mortise antenna joints are coated first with thinner epoxy to allow it to soak into the wood I am using West's system epoxy for this project foreign [Music] next I made some thickened epoxy with West system 403 microfibers this thickened epoxy will be used in the mortars antenna joints to fill up any gaps and Imperfections [Music] foreign [Music] I forgot to put epoxy on the arm faces to be joined so I had to make another batch of thinner epoxy to complete this task my working time with this epoxy at my home temperature of 65 Fahrenheit is about two hours so I have plenty of time to get this put together with all the pieces glued and in place I can now clamp everything to the support board I would have added long clamps to hold the joints tight but they are buried in my storage unit somewhere after curing the clamps and support Port can be removed I then spend some time cleaning up the excess glue and sanding it a bit I have added new pencil lines to define the locations of the arms and this is what the frame looks like now that it is all glued together I'm holding it here to help you better judge the scale of this project there's more to come with this project so stay tuned for our next episode where we will add the supports bases and start refining to the final shape thank you for watching and see you in the next episode
