This video documents the unveiling and first production run of the "Abom79" workshop's first official in-house product: a CNC-machined aluminum drill index. The creator details the entire journey, from the personal inspiration drawn from his collection of classic drill indexes to the modern manufacturing process on his Miltronics CNC mill. Key aspects covered include the design philosophy, the introduction of a new CNC-specific logo, and the technical challenges of achieving precise hole tolerances for a functional fit. The video also touches on the business side of small-scale manufacturing, discussing the process of determining costs, dealing with material price fluctuations, and planning for future product variations, including different sizes and anodized color options. This project represents a significant milestone, marking the creator's deliberate shift from one-off repair and job-shop work to establishing his own line of manufactured products.
Abom79 Unveils First In-House Product: The CNC-Machined Drill Index
0:02:52 Machining Montage: The video begins with an extended sequence showcasing the CNC milling machine in action, cutting, drilling, and shaping the aluminum blocks that will become the drill indexes.
0:37:50 The First Official Product: The creator, Abom79, proudly presents his first manufactured product: a 29-piece fractional drill index, machined from solid aluminum.
0:38:30 Design and Inspiration: He explains that the design is inspired by his personal collection of classic drill indexes but has been customized to feature his new, modern CNC logo, which represents the CNC machining side of his shop.
0:39:48 Plans for Expansion: This is the first of many planned products. Future ideas include versions with his classic logo, as well as indexes for letter, number, metric, and tap/drill sets.
0:40:35 The Realities of Production: The final price is still being determined, as it depends on the total production time and fluctuating material costs for this first batch of 102 pieces. The goal is to make it an affordable, high-quality tool.
0:41:34 A New Business Direction: This project marks a major step in a three-year journey to move beyond one-off jobs and use his CNC machines to manufacture and sell a line of his own products, creating a new revenue stream for the shop.
0:43:06 Improving Efficiency: The video shows "Operation 1" (machining the top). While currently machining two parts at once, he is actively developing new workholding solutions to increase capacity to four or more parts per cycle.
0:44:10 Finishing Touches: He has sent prototypes out to be anodized and plans to offer options for different colors. He is also considering a clear anodized finish to highlight the quality of the raw machine finish.
0:45:32 The Challenge of Precision: He details the difficulty of getting the hole sizes perfect. Using a full set of pin gauges, he is aiming for a tolerance of +0.002" to +0.003" over the nominal drill size to ensure the drills fit smoothly without being too loose or sticking.
0:48:11 The Future is Manufacturing: He expresses his hope that the first batch sells out quickly, which would justify keeping the machines running and producing more. With a second CNC mill on order, the goal is to have two machines constantly making parts.
