After joining and gluing the Australian Cedar halves together for the back and top I then cut out the shape of the guitar using a Coping Saw. I had made a 3mm-thick MDF template of the shape I intended. I didn't follow the shape on the plan slavishly but came up with a shape that was pleasing to my eye and didn't have too sharp a curve at the waist as I had had problems previously with Cedar buckling when bent to tight curves. I traced the shape onto the planed surface of the Cedar soundboard plate and began to cut the outline. I made my first mistake. I had previously drawn the outline of a different shape on the wood and accidentally began to follow the wrong line. I realized my mistake just in time. I redrew the shape onto the plate with a thick 2B pencil so that I wouldn't make the same error. Thankfully the plate was large enough that I could flip it around. However, the cut I had made encroached onto the soundboard a couple of millimetres, so I'm going to have to cover this mistake somehow later on. Having cut out the shape I set about hand planing the plate. This was the first time I had hand planed Australian Cedar and found I had a lot of difficulty. The iron would skate over the wood instead and digging in and when it did dig in the shavings would clog the mouth of the plane. I tried all my different planes and found the same problem. I also got a lot of tear-out. I tried sharpening the plane irons on my trusty antique oil stone and found it made little difference. I looked up online about planing Australian Cedar and read that "some difficulty may be encountered when planing interlocked grain". Very frustrating. I began to wonder if I would have to abandon trying to hand plane the soundboard to thickness and resort to a thickness planer. I decided to put the top and back aside and rethink the whole thing! I turned my attention to the Mahogany neck blank and began to plane it to square. The Mahogany planed easily so maybe it was the Cedar I was using that was the problem and not me? I'm thinking That I will probably machine plane the soundboard to thickness as I have access to such a device. More research required...
