Questions: Damaged Ironbird

Questions: Damaged Ironbird

Adam from the Internet asks:

I have a B.C. Rich 2003 Platinum Pro Ironbird. Got seriously damaged in shipping. The body has five cracks, in some places that I don’t know are even possible to fix. I play technical death metal, black metal, Gothenburg death metal, and all those styles, my favorite being neo-classical metal. The body is agathis. I have an EMG Zakk Wylde set in it. (I could care less about Zakk Wylde. The set, though, is the standard 85/81 combo.) There is a large crack that goes down the middle of the body from where the neck goes on (bolt on neck — the action is great though), then two cracks around the cutaway near the neck (I need to have that so I can have fast access to the 24th fret). There’s another on the back that’s spread just past the serial number plate. I think I’d just want to fix it so I could play it again. I’m not at all concerned about looks right now.

John Calkin from Greenville, Virginia responds:

Go to a hobby shop and buy water-thin superglue. Also buy superglue accelerator. Take all the hardware and electronics off the guitar. Mask off the cracks with a heavy coat of good car wax — don’t use tape. Push/tap the broken wood back into alignment and trickle in some superglue. It will wick into the crack. If it wants to run out of the crack into a cavity or out the other side of the guitar, use some accelerator to solidify it at the point of runout, not at the fill point of the crack. Keep trickling the glue in. Work slowly and keep looking for exit points for the glue so you don’t make a big mess on the other side of the guitar or something. Keep wiping the glue buildup off the wax and rewax as many times as you have to to keep the paint surfaces clean. Eventually the wood will be completely sealed inside and the glue will stop seeping in. It’s almost like welding wood. If you’ve been careful, there should only be a line of glue right at the crack to clean up. Scrape it clean with a razor blade, sand level with 1000 grit wet/dry paper, polish with automotive rubbing compound, and you are good to go.

I’d bet a lot of money that your guitar will be as sound as it ever was if you do this right. I also have to warn you that I’ve seen guys make a horrible mess of their guitars trying to do this, with glue drips and buildup everywhere. But unless they ran glue into the pots or something, their guitars were fixed. If this sounds intimidating, find a pro to do it. It’s not that big of a deal, you just have to be very careful.

Chris Brandt Says You Can’t Succeed in Business Without Really Trying

When he was eleven, Chris Brandt converted a $13 guitar into a 12-string by installing autoharp pins. He now owns a successful repair shop in the Portland area. I visited him there to find out how he makes it work.


Chris, you have almost always worked with other luthiers, either as an employee, in a cooperative shop, or as an employer of several repairmen. You seem to prefer working with others. Why is that?

There are a lot of benefits to working in a shop with other repairmen. It’s a rich learning situation. You are exposed to so many more instruments. It enables you to specialize more, and conversely, to not specialize where you don’t need to. There are a lot of jobs which I don’t do anymore simply because I don’t need to and they’re not my preferred jobs.

Violin Setups, Part One

Violin Setups, Part Two by Michael Darnton



Setups represent one of the most important aspects of violin work. They are the most changeable part of a violin and can make the difference between a customer liking or hating a violin. People who do setups for a living in large shops do a lot of them — countless numbers of bridges, pegs, posts, and nuts. If you’re making one or two or twenty instruments a year you’re not going to be doing many setups. For the people who do those things everyday, it’s a very specialized art and they have very rigorous standards. With that in mind I’m going to try to communicate to you some of those standards, along with some actual “how-to” hints.

Tools

A bench hook (Photo 1) is simply a piece of wood that has a strip nailed to the bottom on one end and a strip nailed to the top on the other end. It hooks over the front edge of the bench and gives a stop to work against. On the under side of my bench hook I’ve glued a piece of sandpaper (Photo 2). If a tiny, thin piece of wood needs to be planed thinner, I flip over the bench hook and use the sandpaper as a traction area.

Shortening Schaller Shafts

Shortening Schaller Shafts

I’ve been making a Yugoslav folk instrument called prim. It’s something like a small mandolin; the scale is 15 1/4". For tuning machines, I’ve been using Schaller M6 minis, but I’ve been modifying them to solve some problems: the peghead is only 3/8" thick, and the threaded bushings that come with the Schallers don’t tighten down this far; the instrument tends to be too heavy at the head; and I have trouble getting enough string angle over the nut.

The photos show what I’ve done to the Schallers. The threaded bushings have been shortened; the metal knobs have been replaced by the proverbial Handsome Pearlescent Plastic; and the shafts have been cut down short and reshaped.

A Case of Explosion Damage

A Case of Explosion Damage

by Keith Davis

Originally published in American Lutherie #15, 1988



In the course of operating a violin shop we have seen all sorts of typical and not-so-typical repair jobs come in, as every shop does. The average day brings a dropped soundpost, a broken bridge, some cracks and so forth. But we were recently called on to repair a series of problems in the instruments of the high school orchestra following a natural gas explosion .

On January 13, 1988 a leak in an underground line allowed gas to build up in the boys’ locker room and weight room of the West Iron County High School. When a coach flipped a light switch the resulting spark apparently set off the explosion, which injured approximately twenty students and staff. The orchestra had stored their instruments in a nearby room and the explosion and shock wave following it caused many of the instruments’ soundposts to either fall or shift position. It is our opinion that the position of the instrument at the time determined whether the post fell or was relocated. Several bridges broke, both violins and ‘celli being so affected. As a point of interest, no viola damage was reported.
