pressors. Sleeves fit the Lucid drum only — not standard rotary or orbital polishers. ## Key facts - The 3.5" drum and narrow working profile reach leading-edge inside radii and tight rivet borders that a 7" pad cannot. (source: Drum diameter 3.5" + narrow profile (Lucid product description verified 2026-05-25)) - Sleeve unit price: drum 27.5 USD — Lucid drum-buffer sleeves are $27.50 each across three variants: wool, cotton, 50/50 blend. Sleeves fit the Lucid axial drum only; they do not fit standard rotary or orbital polishers. (source: https://store.lucid-aero.com/products/drum-buffer-buffing-sleeves (verified 2026-05-25)) - Lucid drum buffer price: drum 2426 USD — The Lucid Aero Compact Drum Buffer retails at $2,426 (sale; $2,699 regular). (source: https://store.lucid-aero.com/products/lucid-aero-compact-drum-buffer (verified 2026-05-25)) - Total cost of entry — buffer plus minimum compressor: drum 2426 USD — Total entry cost for the 3.5" Lucid pneumatic drum buffer is far below a comparable 7" pneumatic buffer once required compressor capacity is included. (source: Lucid store $2,426 sale / $2,699 reg verified 2026-05-25; competitor model + min compressor spec — Derek to supply) - Pad/drum contact surface speed at 1,800 RPM: drum 16.5 ft/s, rotary 33 ft/s — At 1,800 RPM a 7" rotary pad has edge surface speed near 33 ft/s; a 3.5" drum at the same RPM is half that at the contact patch. (source: Surface speed = π× diameter × RPM ÷ 60. Standard kinematics.) - The axial drum's pad travels linearly across the work, so it does not leave the circular swirl or hologram marks a spinning rotary disc can produce on aluminum. (source: Geometry: rotational vs linear contact path.
