Shopmade Luthier Tools #11: Get a grip on your bow!

01-05-2017 08:05 PM by Dave Rutan | 0 comments »

See more photos on my project page [link] A bow vise is used to hold a violin bow while replacing the horse hair that vibrates the strings. I started by looking up such a thing and finding photos of (mostly) the commercially available models. Then I printed out a few screen shots for the details. I didn’t absolutely duplicate the commercial model, but I got something that will work. The wood is oak throughout. A few bibs and bobs of the hardware will be replaced with brass once I ge...

Shopmade Luthier Tools #10: Blunt push stick

01-04-2017 11:56 PM by Dave Rutan | 0 comments »

If this looks like a screwdriver with the business end cut off, you’re not far off. One of the luthiers I watched used just that to push the little maple plugs/wedges in to secure the hair in the bow. I decided to make mine from scratch anyway. The handle is a scrap piece of mahogany this time with a ferrule attached. The push stick is a piece of rod from an old pendaflex folder frame. I just made sure I slightly rounded the business end and smoothed it so that it wouldn’...

Shopmade Luthier Tools #9: Tiny file with Cheap-A handle

01-04-2017 11:31 PM by Dave Rutan | 1 comment »

In one of the videos I watched on bow re-hairing, it was sugested that a tiny rat tail file would come in handy. I happen to have a double set of tiny files, so I thought I’d put a handle on the one I apparently need. I took one of the easily discarded wooden handles from a used foam brush and drilled out the plastic tang that remained in the handle. Then I fit a copper ferrule on it and glued in the file. (The hole was just a bit loose for the file tang.) I did a bit of sanding...

Shopmade Luthier Tools #8: Hook

01-04-2017 12:52 PM by Dave Rutan | 0 comments »

This tool is made from the business end of one of those nut picks that come with nut cracking sets. In a video about bow re-hairing I saw the technician using a tool like this to push the abalone slide back over the hair on the frog end of the bow. I sad to myself ‘I can make one of those!’ After cutting the nut pick in two, I mounted it in a scrap piece of white oak and strengthened it witrh a ferrule. Even so, I learned that the hole you drill to accept the tool ne...

Shopmade Luthier Tools #7: Pick

01-04-2017 11:50 AM by Dave Rutan | 0 comments »

Call this a pick or a bodkin. It is chiefly used to nudge out the maple ‘wedges’ that hold the horse hair in at either end of a bow. I made mine from half of one of those nut picks that come with nut cracker sets. After cutting the nut pick in two, I chucked it in my electric drill (corded) and sharpened it on my belt grinder till it gained a nice long point. Then I mounted it in a scrap piece of white oak with a copper ferrule. The handle was finished with boiled linseed oi...

Shopmade Luthier Tools #6: Brass hair gauge

01-04-2017 02:41 AM by Dave Rutan | 0 comments »

What’s a hair gauge you ask? When a luthier re-hairs a violin bow, or a bow of any of the other bowed instruments, they don’t just cram a bunch of horse hair into the little anchor holes. There is a certain yet indefinite amount of hair required for each type of bow. Greatly experienced professionals can pretty much gauge it by their hands, but some like to do it scientifically. Hair gauges are available for purchase and there are several types. There’s even...

Shopmade Luthier Tools #5: Tiny knife/scraper

01-03-2017 11:59 PM by Dave Rutan | 0 comments »

While we’re on the subject of knives, this one, while it is a knife, will principally be used as a scraper in tight spaces. The blade began life as the awl in the cheap pocket knife that I mentioned a few posts ago. The handle is a scrap of white oak from the hardwood scrap drawer. (I have a hardwood scrap box as well.) The knife was finished with boiled linseed oil. Check out the other luthier tools I’ve made here:[link] Enjoy a few more pictures:

Make a Lathe Tool Rack

01-03-2017 11:32 PM by A Slice of Wood Workshop | 1 comment »

Instead of leaving my lathe tools laying around and always getting in the way, I created a rack to hold them with a few additional spaces for future expansion. I was able to use scrap lumber and fill in a void area in my shop. Take a look at the project, leave comments, and subscribe.

Shopmade Luthier Tools #4: Knife

01-03-2017 09:51 PM by Dave Rutan | 2 comments »

The luthier’s knife looks very much to me like a common carpenter’s striking or marking knife. Be that as it may, I don’t have either, so I made one. I started with an old, dull 3/4 inch spade bit. I marked a 45 degree angle on it and grouned it down with my bench grinder, keeping it cool with frequent water dippings. I then used my belt grinder to put a bevel on one side of the blade. I honed it to sharpness on a whetstone. It’s not scary sharp, but it’s sharp. Fo...

Shopmade Luthier Tools #3: Tiny chisel/scraper

01-03-2017 01:49 PM by Dave Rutan | 2 comments »

Even though this is technically a chisel, it is used principally as a scraper to get hardened glue out of the small wells in a violin bow where the ends of the hair hank are anchored. I fashioned the blade of this chisel from the Phillips screw driver ‘blade’ of an old, low quality pocket knife. It was not a genuine Swiss Army knife, but a bad, cheap knockoff. The blades loosened up after a few years and the knife lived in my tool box for ‘just in case’. I general...
