MacRostie Binding Trimmer

About This Item

Quick, easy and precise custom bindings!
The easiest way to custom-size wood or plastic bindings for a perfect fit!

Precisely duplicate the dimensions of older bindings for repair and restoration work, too. The MacRostie Binding Trimmer's precision dimensioning gauge and custom adjustable fence give you accurate, repeatable results. Your bindings will fit better, with tedious scraping and sanding virtually eliminated after they're glued in place.

"It's an invaluable tool for custom binding work. There's nothing else like it."
—Ken Fallon, guitar repairman and backline tech for the Rolling Stones

Order the MacRostie Binding Trimmer complete with bit and 1-hp. Bosch Colt router, or use your own shop router.

"I use this for my custom bindings, and wouldn't want to be without it. On vintage repairs, it lets me resize a new binding so it drops into the old slot perfectly." —Bryan Galloup, Galloup Guitars

The Binding Trimmer was developed and refined by Stewart-MacDonald's Don MacRostie. Vertical and horizontal spring-tension hold-downs tame flexible binding materials for trimming to as thin as 1/16" as you pull them through the bit. The sturdy plywood router base is drilled to fit the Bosch Colt router (you can easily redrill for your own shop router if desired.) Complete photo-illustrated setup instructions are included.

The durable carbide-tipped bit has a long 1/4" -diameter shank and 1/2" cutting height. (Note: If you already have our ball-bearing router bit, it will also work.)

The Bosch Colt Router is a 120-volt AC electrical appliance with a U.S. standard Type A plug with two flat parallel prongs, ungrounded. For more specifications see the Bosch Colt Router.

MacRostie Binding Trimmer


Verified Buyer

I am not impressed with this trimmer. It works, but you have to be extremely careful not to move the binding in the wrong direction. The hold down for the binding is not strong enough. I ruined a lot of binding before I figured out how to use it. I use both hands to hold it into the fence so it doesn't move towards the cutter.


The right tool for the job


This is a great tool to quickly and accurately take down binding to just the size you need. It's good for cleaning up laminated pieces of perfling. One question though: would a spiral cutting bit be useful to reduce chipping and tear out on figured wood binding?
