The Clark Foam Surfboard Planer CF 1449 is a specialized tool designed for surfboard shaping. Sheartak crated a shaping drum which is equipped with 14 carbide knives. Each knife has four sharp edges.
The Sheartak shaping drum is specifically designed for surfboard shaping, and it's an excellent tool for surfboard builders who want to fine-tune and achieve a smooth, professional finish on their boards. When surfacing a surfboard, particularly after rough shaping, the goal is to refine the contours, edges, and overall finish. Here’s a deeper dive into how the Sheartak shaping drum is used and why it’s a popular choice for surfboard shaping:
Key Features of Sheartak Shaping Drums:
-
Precision in Shaping: The Sheartak shaping drum is particularly useful for creating consistent, smooth curves and edges. It works well on both the rail areas and the deck, offering a high degree of control, especially when fine-tuning curves and transitions.
-
Durability: Sheartak shaping drums are built to last, providing a longer lifespan compared to other sanding or shaping drums. They can handle the rough and repetitive work involved in shaping surfboards without losing their effectiveness.
-
Easy to Use with Sanders: These shaping drums are designed to work with power planers, which helps in speeding up the surfboard shaping process, ensuring precision while reducing fatigue.
-
Specialized for Foam and Resin: Sheartak drums are ideal for surfboard foam, which can be tricky to sand evenly due to its softness and porous nature. They provide a way to smooth the foam without damaging the integrity of the shape.
Using Sheartak Shaping Drums for Surfacing:
-
Smoothing Contours: After the rough shape of the surfboard is created (whether it’s for a shortboard, longboard, or any other type), you can use the Sheartak shaping drum to smooth the contours and finish the outline.
-
Refining Rails and Concaves: It helps in carefully refining rails (the edges of the surfboard) and concaves, allowing the shaper to get those delicate transitions just right.
-
Finishing: Once the rough sanding is done, Sheartak shaping drums can be used in the final steps to ensure an even and high-quality finish.

Do I need to replace the original bearings?
If the bearings in your machine are in good condition, they can be reused by carefully removing them with a bearing or pulley puller. However, if the bearings are tightly pressed onto the shaft, removal may cause damage. To minimize this risk, we recommend replacing old bearings with our greased and sealed bearings, designed for long-lasting performance. For a smooth upgrade, we suggest adding the bearings to your shopping cart before completing your purchase.
We provide premium bearings from NSK, SKF, NTN, FAG, Timken. They are renowned for their high quality and performance, designed to provide durability and reliability in various applications
If you add the bearings to your order, we will preinstall them for you when premounting is possible, saving you the hassle of doing it yourself.
Do I need to to Add a Few Boxes of Carbide Inserts
We provide 5 carbide inserts and 5 screws as spare parts. However, many of our customers choose to purchase additional boxes, as the shipping costs for separate purchases can make it less economical.
Do I need a Torque Wrench?
To securely lock the carbide inserts, we recommend applying a torque of 48 to 52 Pound-Inches (or 5.42 to 5.88 Newton-Meters). (Note: 1 Newton-Meter is equal to 8.851 Pound-Inches, and 1 Pound-Inch is approximately 0.113 Newton-Meters.) It is crucial not to apply excessive torque, as this could cause the carbide inserts to crack or explode. On the other hand, using too little torque may result in the inserts not being properly secured, which could lead to cracks, shattering, or uneven height on the cutter block, causing ridges or lines on the board.
If one person is responsible for maintaining the machine, they can typically apply the same torque consistently without a torque wrench. However, when multiple people are involved in machine maintenance, ensuring uniform torque application can be challenging. For consistency and peace of mind, we recommend using a torque wrench.
What kind of steel the cutter block is made of?
The cutter block is constructed using GB/T 40Cr, a structural alloy steel of the same caliber as ASTM grade 5140, AISI 5140, SAE 5140, DIN 41Cr4, BS 41Cr4, JIS SCr440, and EN 41Cr4.The primary components of this steel are as follows: carbon (C) at a range of 0.37-0.44%, silicon (Si) between 0.17-0.37%, manganese (Mn) within 0.50-0.80%, and chromium (Cr) from 0.80-1.10%.
In terms of physical properties, this steel exhibits a tensile strength range of 115-234σb/MPa, a yield strength of 2σ 0.2 ≥/MPa, and an elongation capacity of 65 δ5≥ (%). It also has a HBS range of 123-321 and a HRC rating of 30.
This alloy steel is frequently utilized in low to moderately stressed components for machines, engines, and vehicles.
