I've started working on the tailpiece again. My old 4" angle grinder broke, so I had to get a new one. First the wheel is shaped so that it will make a round groove, then grooves are cut on both sides of the billet, offset from one side to the other. Before grinding: After: To be continued... |

Well, the binding is all glued on now. I'm not real happy with the fit of the top bindings though. Before I do another archtop, I need to build a binding router jig thing... I painted the channels with shellac first: The bindings. They came out of the bender a little lumpy in some spots, so I had to touch them up on the iron: I also worked on the fingerboard a little. I tapered it and added side position markers: I'll finish forging the tailpiece tomorrow, and will probably be able to string it up, "in the white", shortly thereafter. |

I actually haven't done anything on this project since last weekend, but here's some more pics from then. The binding scraped on the top and back. Have to do the sides yet: The inserts, inserted: The neck joint flossed: The wedge glued to the neck: The fingerboard radiused: |

The tailpiece. Sorry, I missed some intermediate steps. Basically, I drilled the holes, then used a torch to soften the area I wanted it to bend, and bent it. I think I may be scrapping this one because it's not wide enough. We'll see. I used a small cut off wheel in my Foredom and needle files to make the string slots. |

So how's this baby coming along? Waiting for finish to cure, or do you still have it strung up in the white? And what are your thoughts on eastern red cedar as a top wood? There's a guy over on delcamp asking about it, says there's a guy somewhere in Missouri with a bunch and could cut guitar tops if there's interest. Excellent work, by the way. I think this is my favorite build in the challenge so far. Love the color scheme, shape, F holes, everything. I've been wanting to try an arched top with flat back like that, and wondered why nobody ever did it. Arched back makes sense for soundpost instruments, but flat seems like it would work better for guitar style instruments... plus it saves a bunch of wood and painful hardwood carving. Carving the top is fun though Definite points for forging your own steel tailpiece Looks great. Not a fan of the hex bolt though. Stick a wood pin in that thing! Can't wait to hear sound clips. |

Really cool build. Nice job carving the plates. I replaced some plastic handles on some chisels with curly maple and used copper pipe for ferrels, your hand made ones look really nice. I've been into forged knives for a long time, I have a couple of Jerry Fisk knives, should have three one got stolen. |

It's coming along pretty well. I hadn't really done anything on it for a couple months, then realized the deadline is quickly approaching, and I'd better get moving. So, a few weeks ago I shaped the neck, and this week finished sanding and started spraying. I did have it strung up in the white, and it sounded pretty good. I think the eastern red cedar is fine as a top wood, but you won't see it used much, since it's so hard to find pieces big enough without knots. Don't worry, I'll be making an osage endpin.

Ok, here's the first round of the semi-final pics: The neck before shaping: I use a belt grinder called the KMG (knife makers grinder) from Beaumont Metal Works. A wonderful tool. I'd be lost without it. Here it's set up with the small wheel attachment: After shaping the way I want, I use a different attachment, with a slack 240 grit belt to remove the 40 grit scratches: All smoothed out: I'm finishing this neck with Tru-oil. Here it is with one coat on: |

I decided I didn't like the color of the top, so I'm painting it gray: Just kidding! I'm actually using the paint to help me find any imperfections on the top: I'm not pore filling this instrument. I'm doing a quick and dirty finish. First, a couple coats of shellac, then sand it smooth: |

Post subject: | Re: My challenge build |
Then lacquer. I'm using Watco brushing lacquer, because I have it, and want to use it up. Since I'm not pore filling, it would be pointless to sand this all the way up through the grits and buff, so I'm just going to spray a dozen coats, level, then spray one more very thin coat. At this point, I need to let the lacquer harden a couple days before I level it. This brushing lacquer takes awhile to harden... |

Now, the tailpiece. I heat treated it because hardened and tempered damascus gives much better contrast than soft (annealed). Before etching: After etching: After buffing: I repeated the etching/buff process a couple more times, etched it one last time, and left it in the neutralizing bath for several weeks. Then I lightly sanded it with very fine paper to bring a shine to the bright layers, while leaving the others dark. Then I sprayed several coats of lacquer to keep prevent rust. As soon as I find the tailpiece, I'll take some pics of it... |

That damascus tailpiece is cheating........ thats awesome. Would you be interested in doing a couple of mandolin tailpieces? |

Post subject: | Re: My challenge build |
It's a very cool little instrument, Phillip. I've enjoyed following along with it. I like your choices throughout. At first, I didn't think I'd like the bindings, but they work very well. I'm especially impressed with the way you brought out the pattern in the damascus steel. That's beautiful. Patrick |

That tailpiece is awesome. So after you cut grooves into it, did you just hammer it flat, or was there more to the process? |

The design needs some tweaking first. muskr@ wrote: That tailpiece is awesome. So after you cut grooves into it, did you just hammer it flat, or was there more to the process? Yes, after grinding the grooves were cut, then I hammered it flat, then forged it down to the final as-forged thickness, then ground it down to about 1/16" thick. Ok, here are the final in-progress pics: Making the tail pin: Next post, finished pics. |

Assembly was just a matter of bolting everything together. And adjusting the bridge height. I'm not sure I'll leave the bridge the way it is. I might "skeletonize" it like a violin bridge. |

I love the sound. It's sort of like a mando but smoother. |
