String winders made in Fort Collins, Colorado

I make all of the string winders in my workshop

I start with curly maple blanks and machine them on my CNC router using a program I wrote specifically for cutting out the winder cranks.


I sand or buff each string winder by hand at least five times before it is a finished product.


I look for handles that make a nice contrast to the curly maple cranks.  They require lots of sanding too!

I usually ship the winders within two days

I try to keep enough inventory of the different crank types and the different handle woods so that I can assemble, wax, package, and mail within two days.


I have been known to take some vacations, so  if I am out of town I will do my best to email you an estimated date of shipping.

Order using PayPal

I like using PayPal.  I also think it is a good deal for you since it offers buyer protection.  


I try to keep up with the Post Office rates for first class postage and only charge you what I am charged.   If you order two winders the postage rate is the same as for a single.

Ordering the correct string winder size

Each string winder crank is cut from curly maple to the dimensions identified

Thickness (T)

Width (W)

Depth (D)

Make sure you know what size tuner you have when you order

A string winder that is larger than your tuner will probably work but will have a sloppy fit.  A string winder with a thickness or width smaller that your tuner, will not work!  Check your size with a caliper if you are unsure.

Mandolin String Winders

F-Style (Fits tuners by Waverly and Schaller)

Thickness = 0.29"

Width = 0.58"

Depth = 0.5"


These string winders are designed to turn without hitting the outside D and A string tuners.

F-Style for large tuner buttons (Fits tuners by Grover)

Thickness = 0.32"

Width = 0.62"

Depth = 0.5"


Like the standard F-style string winder, these are designed to turn without hitting the outside D and A string tuners.

A-Style (Fits most A style mandolins)

Thickness = 0.32"

Width = 0.62"

Depth = 0.5"


A styles have a shorter crank since the tuners are aligned in a row.  They fit the same tuner dimensions as the F-Style for large tuner buttons.

Guitar String Winders

Small Butterbean

 Thickness = 0.26"

Width = 0.79"

Depth = 0.5"


These string winders fit the smaller tuner buttons found on guitars like my Martin Custom 15 or the Collings D1-A in the photo.

Large guitar (fit Grover tuners)

Thickness = 0.33"

Width = 0.79"

Depth = 0.6"


These string winders fit the larger tuners.

Medium size guitar

Thickness = 0.29"

Width = 0.93"

Depth = 0.5"


When the Butterbean is too small and the Grover is too big

Thickness = 0.32"

Width = 0.62"

Small Butterbean guitar winders

Custom String Winders

Let me make a custom winder for you

Over the years, I have made special sized winders for banjos, dobros, basses, and lots of other stringed instruments.  I can do this by making some changes to my CNC milling machine program.  Once I have the dimensions, I can cut the string winder to the size that your instrument needs.

How to order

To order a custom string winder I need an email from you with the Thickness, Width, and Depth of your tuner button and any other important information to ensure that the winder will fit properly. This is also a chance for you to ask for a handle wood not on my standard list.  I will respond to your email, and when we have an agreement of what is needed, you can place an order.

Delivery Time

Since I need to create the CNC program and machine the string winder as a special, it will usually take a couple weeks for me to finish and ship to you.
