[QUOTE="naboo, post: 1150841, member: 23125"] The next step is to shape the horn. This had me very nervous - it looks like it's very difficult, and if you FF it up, there is no undo button. I don't have much patience so I just dived in. Luckily, it was a lot easier than I thought. Start with the planer on about 1.5mm and once the edges are gone go down to 0.5mm and if you're scared stop and carry on tomorrow. Even go as low as 0.1. If you just follow the contours consistently, it actually comes out very nice. I honestly thought this would be the hardest part of the build, but it turned out to be easy. First, clamp the piece on the corner of a sturdy table. [ATTACH type="full" width="593px"]29842[/ATTACH] Plane a little bit. [ATTACH type="full" width="410px"]29843[/ATTACH] That's it, keep going until your arm feels like you're back in puberty. Do a bit of sanding for the obvious defects (after your arm has rested a bit). [ATTACH type="full" width="528px"]29844[/ATTACH] Before you know it, it's done and *coughs* dusted. [ATTACH type="full" width="569px"]29845[/ATTACH] [/QUOTE]
