the Heavy-6


A Formidable Endgame for the FC660C

Perhaps gravitas is a good term for it: an object that, by sheer virtue of its weight, commands respect and attention. The Heavy-6 is my answer to the inherent density and compact nature of Leopold's beautiful FC660C keyboard. This housing (along with its optional custom carry case) aims, quite simply, to be the ultimate after-market upgrade for that widely esteemed keyboard. With the keyboard installed, the custom CNC-machined Heavy-6 weighs in at over 7 pounds in its all-steel form—dubbed the Monolith—and at over 4 pounds otherwise.

If you're new to my work, check out the kind praise I've won from existing clients.

Note: I have re-opened this pre-order in limited quantities, with all units scheduled to ship around the end of March. The machined parts are all complete and are currently undergoing powder-coating here in California. 


I'm offering this design in a highly-curated selection of materials and finishes. All versions include a stainless steel backplate for added weight. The Monolith and Monolivia feature entirely stainless steel parts with PVD coating. All other versions feature an aluminum upper housing and lightly textured, matte-black powder-coated steel backplate. Each version includes my discreet metal, hand-enameled Portcullis maker's mark on the rear of the case, in a complementary color. 

Aerospace: a bead-blasted silver anodized finish—gray Portcullis badge.

Tactical: a bead-blasted black anodized finish—gray Portcullis badge.

Retro Refrigerator: a matte blue-green powder-coat evocative of Midcentury Modern kitchen appliances and typewriters—white Portcullis badge.

Maritime: a matte blue powder-coat—white Portcullis badge.

Aperture: a powder-coated hammertone texture, evocative of the finish used on certain vintage Leica cameras and high-end Japanese tripods—gray Portcullis badge.

Motorsport: a textured vibrant yellow powder coat—red Portcullis badge.

Royal wrinkle: This textured matte black wrinkle powder coat is evocative of midcentury typewriters and electrical equipment housings (video here).

Monolith: an astonishingly heavy all-steel housing with matte black PVD coating (a durable coating primarily used on luxury watches)—purple Portcullis badge.

Monolivia: an astonishingly heavy all-steel housing with a mirror polish and rose gold PVD coating (a durable coating primarily used on luxury watches)—white Portcullis badge.

Custom carry brief option. Made in California.

This ballistic nylon carry bag with soft calfskin leather accents was specifically designed to fit the Heavy-6. It features MOLLE loops at the front, an interior zippered cable pocket, gray tech suede lining, seat-belt style webbing, and military-style snap hooks. Polished gunmetal zipper and slider hardware. The pictured piece is a prototype; some small improvements may be made to the bag before production.

The hand-embroidered patch at the front features my Portcullis maker's mark. It is removable via Velcro, and I will be releasing other compatible keyboard-related patch designs soon. This style of metal-wire hand-embroidery is an ancient handicraft of India, which eventually made its way to Europe to become a traditional part of French and British military regalia and liturgical vestments.

You may add the carry brief to your order here from the group buy page.

Technical specs

The Heavy-6 is compatible with only the Leopold FC660C (not included) keyboard. It has the same angle between desk and typing surface as the original keyboard itself. The Heavy-6 is Hasu-controller compatible. 


This is a made-to-order item; patience required

You can always change your shipping address after you order, but if you need this item by a very specific date, please don't participate in the group buy. I always work with my manufacturers to turn things around as quickly as possible, but for my work, quality is of paramount importance, so I try not to impose arbitrary deadlines on manufacturers. Just rest assured that in the event of any significant delays, I'll keep everyone updated by email and (more regularly) in the Keebtalk thread.

Et alia
This is a DIY kit, keyboard not included, which requires you to remove your FC660C from its stock plastic housing. This may invalidate your keyboard warranty, and by purchasing you agree to take on that project and its results at your own risk. (But, of course, that's also part of the fun.) Assembly is straightforward and I'll produce an instructional video as the shipment date approaches.
