MAMMOTH Inlay Base Board - Premium Hardwood Foundation

Available in Walnut, Cherry & Maple

Elevate your cutting board projects to monumental proportions with our all-new MAMMOTH Inlay Base Board — the heavyweight champion of inlay foundations. Handcrafted in our Texas shop with premium North American hardwoods, this oversized powerhouse is built for makers who refuse to compromise on scale, stability, or visual impact.

At a commanding 2.25 inches thick and a generous 24" x 18" surface, the MAMMOTH base transforms ambitious designs into reality. Whether you're creating an heirloom cutting board, an intricate CNC masterpiece, or a statement piece that demands attention, this is the foundation that delivers.

Features:

• Massive 2.25" Thickness — Over 32% thicker than our standard base, the MAMMOTH provides unparalleled stability, heft, and presence. This isn't just a cutting board base — it's a statement of serious craftsmanship.

• Expansive 24" x 18" Surface — Work big. Design bold. With 432 square inches of premium hardwood canvas, you have the space to bring your most ambitious inlay visions to life without limitations.

• Premium North American Hardwoods — Choose from three classic species, each selected for exceptional grain, durability, and timeless beauty:

  • Walnut: Rich chocolate tones with elegant grain patterns
  • Cherry: Warm reddish-brown hues that deepen beautifully with age
  • Maple: Clean, light tones with subtle grain for maximum contrast

• Precision-Sanded to 180 Grit — Each MAMMOTH base arrives with a silky-smooth surface, ready for oil, epoxy, or your preferred finish. No prep work needed — just apply and admire.

• Handmade in Texas — Every board is individually crafted, inspected, and quality-checked by our experienced team. We ensure each MAMMOTH base meets our exacting standards for flatness, stability, and consistency.

• Perfect for Advanced Projects — The extra thickness and size make the MAMMOTH ideal for deep inlay work, multi-layer designs, complex CNC routing, or simply creating cutting boards that feel as substantial as they look.

• Sustainably Sourced — Our commitment to responsible forestry means you can build with confidence, knowing your materials respect both quality and the environment.

This is for the maker who wants to push boundaries, create larger-than-life pieces, and work with a foundation that can handle anything you throw at it. The extra thickness provides exceptional rigidity for precision routing, while the expanded surface gives you room to explore complex patterns and oversized designs.

Loved the maze kit, was my first build ever from a kit, and it turned out perfect! I just gave the maze to my next door neighbor's granddaughter and she loves it! I have purchased and received 3 more maze kits and will be using them as Christmas presents. Thank you Ryan and all of CIC! Richard Hill '82 Gig 'em Aggies!

Customer photo review of 1/16" x 3/8" O'Flute - 1/8" Shank - OF1025

used the 1/16 to reach the areas that my 1/8 o-flute missed or left rounded. I'd never used a bit that small before, so i used really safe numbers for the speed/feeds. 13mm/sec, DoC:.4mm, plunge=3mm/sec

My first order with CIC after following along on YouTube. Love you guys. The process was smooth and the packaging is absolutely perfect. You can tell they take their time and ship it properly. This project came out perfect. It’s now on display / for sale in my shop at the United States Military Academy, West Point. Huge football following here for Army. I also have the large flag to do now, and I can’t wait to get that out on display.

Customer photo review of Inlay Press Digital File

This was a fun project to cut out on my new Shapeoko CNC, and was one of my first cuts from plans. I learned a great deal, and was inspired to buy two of your inlay kits to begin learning inlay creation and production. Thanks for all you do to support the CNC community. Gig 'em Aggies!

Made mine out of 7/8 x 5 1/2 in stock 5/8 deep. Tool paths were pretty basic and the pieces fit perfectly.

Wood was smooth with no dents or nicks. Good weight to it for a cutting board.

Been woodworking for years but relatively new to CNCing. This project was a ton of fun. The kit was very good and complete, but the real benefit was the accompanying video which made this easier and a good learning project for a newbie. Looking forward to using this at my next tailgate!

I buy lots of material and bits from CIC. I’ve found the products to be superb. These are some projects I recently made for a craft sale. Ryan’s videos have taught me a lot. Thanks much.

Customer video review of Walnut Hardwood Lumber Pack – 13/16" S4S – Free Shipping

Ryan was kinda spot on about the time savings by using premade panels. As a small garage shop business, I lost days at a time trying mill, glue and surface panels. By adjusting my workflow and products around two uniform sizes, no only am I able to keep the CNC humming daily, I spend less time trying to mill everything to the same size or spend time trying to program around various dimensions. Every program gets dialed in one and done. Well done, Ryan! You’re on to something and your new business model should be wildly successful!!

Tried something a little different. Would prefer a better grain match on the blank that’s why I tried the green stain.

Customer photo review of Game Day Board CNC Kit

An easy carve and beautiful result! I downsized it to fit the Cherry workpiece I had and spent a little extra time sanding with finer grit to get the shine I wanted. Added a chamfer to the edges and rubber feet to the underside to give it a bit of pop.

Customer photo review of ColorCore HDPE Plastic - Premium Multi-Layer Engravable Sheets

I love your videos and it seems a great family business. I love reading the personalized wooden cards that come with the orders. A very nice touch! I started running a 3D printing business a year back and decided to start making some CNC projects on the side, but now the signs I have been making seem to be more popular than my 3D prints. Check out SayocaDesigns.com. Keep up the good work and keep inspiring us. Cheers! Steve.

Thanks to Ryan's great video on doing VCarve Inlays and the high quality 30 degree V Cutters that CIC sells, I just recently made this table and the Humming Bird Inlay was done with the CIC 30 degree V Bit. The table is made from Curly Maple and the Humming Bird is Walnut and the Flower is African Rose Wood. The table was made to donate for a fund raising event at our local cancer treatment center.

The board cut great except around the stars. There were several points that chipped out.
