shop talk & drilling aluminum

This video from Skunk Works (0:26) focuses on the proper techniques for drilling holes in aluminum, emphasizing precision and efficiency for manufacturing. The host, an experienced engineer and machinist, shares his extensive knowledge to help viewers understand the correct way to approach metal fabrication, contrasting professional methods with common self-taught approaches. Here's a breakdown of the key topics: Introduction to Tools (1:56): The video introduces various tools used in metalwork, such as automatic punch pressers, different types of aviation tin snips (2:11), and other specialized items. Drilling Best Practices (5:30): The host demonstrates how to drill holes correctly and highlights the importance of using a center punch (6:14) to prevent the drill from "walking." He explains the difference between a center drill tip (16:41) and a standard jobber drill (16:50), emphasizing that the 135-degree split point of a center drill prevents misalignment (17:09). Counter Sinking (7:10): The video explains the purpose of a counter sink and the significance of different angles (e.g., 41-degree included angle vs. 82-degree outside angle) (7:18). This ensures that screw heads sit flush with the material (8:26). Using Center Drills (8:56): The host details the proper use of combination center drills (8:58), stressing the importance of using the correct size (11:05) and only drilling half the angle (9:44) to avoid oversizing and undercuts. Importance of Drill Charts (12:20): The video highlights the necessity of using drill charts to determine precise drill sizes in millimeters and decimals (12:23). Work Area Cleanliness (14:39): The host strongly advocates for maintaining a clean work area (15:01) to prevent damage to materials and reflect professionalism, contrasting it with "dirty pigs work in filth" (15:28). Production Drilling and Deburring (36:02): The video demonstrates techniques for efficient production drilling using positive stops (36:23) to prevent the material from spinning. It also shows a fast deburring process (40:00) for mass production. Creating a New Gauge (42:17): The host demonstrates how to create a new gauge (43:18) for precise hole marking when the original is flawed, using calipers (44:54) and scribing tools (49:28) for accuracy. Professional Expertise and Industry Experience (18:41): The host shares his 35 years of experience (19:08) in manufacturing, including work on military aircraft like the F-35 Striker Force (19:44) and the C-17 (20:38), emphasizing the value of formal training over self-taught methods. Terminology and Machine Operator vs. Machinist (29:08): The host differentiates between a "machinist" and a "machine operator," asserting that formal training (trade school or apprenticeship) (29:59) is necessary to be considered a machinist, while self-taught individuals are machine operators (30:42). aluminum,how to drill holes in aluminum,drill,how to drill a hole in stainless steel,how to drill a hole,how to drill and tap a hole,how to drill into aluminum,drilling holes in aluminum,how to drill through aluminum,aluminum drill hole machine,how to,aluminum profile drill holes,how to drill holes,hole,aluminium,how to tap a hole,how to fix hole in job boat,aluminum profile drilling holes,how to drill metal,hole saw aluminum,drill through aluminum
