Unbleached Bone Nuts

Unbleached Bone Nuts

Stewart-MacDonald is your source for quality bone!
Bone is traditionally favored for quality instruments. Our unbleached bone is even harder than bleached white bone, and has a mottled cream vintage look. Its hardness and density contributes to good tone, it polishes well, and it allows more precise slot filing.

Blank nuts have oversize length and height, for custom shaping in your shop. They're ready for trimming, filing, sanding and slotting.

Preshaped nuts will save you a LOT of work — a head start for the novice builder, and a bonus for the busy repair shop where time is money! The dimensions have been carefully researched, and minor trimming, slotting, and sanding are all that's needed to fit most popular guitars.

Good product but you need to finish curing it yourself.

By

Verified Buyer


Blanks for Gibson.

The good:
Color is nice, fit (thickness) is well-suited to what it's intended for, with ample material for custom shaping.

The not-so-good:
Upon removing the three pieces of bone from the plastic seal envelope, I encountered a tacky, sticky, waxy residue on all their surfaces. It cannot be removed with alcohol, acetone, naphtha, or dish soap / water. I left them in a small, unwaxed paper bag. After one hour, the bag was covered in spots that, curiously, remind one of grease stains on a fast food bag. New bag, another hour, still spots. Repeat. More spotting. Some substance is leaching out of the material. What can this be?
Remember when I said it looks like grease on a fast food bag? That's because that's exactly what it is—lipids that remain in the animal bone. I don't know where this material is sourced from (probably a byproduct of a beef or pork producer, and probably not the same one every quarter), but it isn't adequately cured, which means it's covered in actual fat, which will begin to sweat out even more in transit if not before. This means it isn't actually "harder" as the product description claims. In fact, you can bend it with your hands without much effort. If I make a complete nut out of this material in this state, then no matter how smooth and burnished I make my nut slots, the wound strings under pressure will make impressions in the slot within hours of the final setup, causing binding and tuning stability issues–and questions from dissatisfied clients.

The fix:
This product is quality, you just need to finish the curing yourself. If you don't want to wait days, weeks, or potentially months for a natural cure, then bake it for 15 minutes at 350 degrees Fahrenheit (convection oven). Remove, wipe down the ~2 CCs of grease that sweated out, and allow to cool thoroughly. Now you've got a piece of material you can work with.

Violin nut.

By

Verified Buyer


I had a customer insisting on having a bone nut for his violin to sharpen and clarify the tone. It seems to be working for his violin and is very happy with the results. He now wants to do the same for his viola but none of the bone nuts are tall enough to fit to the viola. What would be helpful if there were larger bone blanks.

Great tone.

By

Verified Buyer


The bone is a little tougher to work with. (Filing and sanding) but the tone is well worth the extra effort.
