Simple Test Build:
Dual 22g 316L Ø3.75mm 7/6 wrap. Expected resistance of 0.11Ω to 0.12Ω. A
Scotts Mod ORDTS.2 firing multimeter was used to examine the voltage drop characteristics of several brown HB4 cells on a similarly built
K24 before use in the
Ruby.

Positive Impressions:
• Domed chamber of top cap improves laminar flow.
• Completely tool-free take down reduces maintenance time.
• Juice overflows along the exterior of the mod and not to the 510.
• Single piece button/contact eliminates the prospect of contact cam-out.
• Larger center post hole accomodates larger builds such as dual twisted 22g.
• True hybrid design equates to fewer points of failure with threads located at the switch only.
• Superb heatsinking qualities of hybrid mods reduce carbonization along coil builds.
• Multiple cap and tip options help dictate the overall vaping experience.
• Dragon Cap | Slam Cap 24 | Demon Cap 24 | Fat Dragon Tip
• Self-adjusting switch = No pins or POM insulators to calibrate.
• Multiple finishes satisfy aesthetic and durability concerns.

Negative Impressions:
• Verifying resistance requires the use of an analog/digital VM/MM/mΩ Meter.
• Negative contact protection and maintenance requires the use of an extension tool.
• 1/4" Acetal rod cut to size is a widely available extension solution.
• Limited to the build deck of the
Kennedy 24 (with a larger center post).
• Building on the mod can be awkward due to odd angles of leverage.
• VapeNutt VNC and/or padded vise provide adequate stability for rebuilding.

Additional Commentary:
This post offers a recommended method to check for resistances ≥ 0.1Ω. A short will reveal itself as a ranging ohm reading. An experimental build should be tested on a
K24 and its resistance verified on a high-quality meter as a point of reference. The
Ruby is ~1mm shorter than a
K24 on a
Roundhouse. Outside of being a true hybrid, the design of the switch is perhaps the highlight of the mod. Self-adjusting, single piece button/contact. Large positive/negative contact and threaded surface areas. Make no mistake about it: The
Ruby is designed for use with the battery positive oriented in the direction of the switch. Please do verify the integrity of your wraps before cell installation. The switch should be finger-tightened only. This facilitates the emergency opening of the circuit in the event of a failure. The use of a drive tool to apply additional fastening torque is strongly discouraged. Suggested ways to maintain the upper negative contact include sandpaper or a wad of Scotch-Brite on an extension tool, the use of a fiberglass scratch pen, or a common pencil eraser. Contact protection is recommended in the form of an applied corrosion inhibitor (e.g. extended temperature DeOxit Gold GxL/Gx2 Series). Consider the application of a conductive lubricant (e.g. DeOxit Gold G-Series) to the detente where the copper wings of the contact are seated in order to reduce kinetic friction when the firing button is engaged. I would have preferred the firing spring be wound from C17500 or C17510 beryllium copper. Decapping is the recommended filling method. Rather than painting coils, best results are obtained by saturating the cavities in between the deck and the airflow tubes/negative posts. The
Fat Dragon Tip has proven to be an effective means to increase negative draw volume and allows for personalization with a number of material and color choices. The limited production Slam Cap 24 reduces the chamber and the vapor delivery path to provide flavor chasers with the condensed vapor they seek. Final thought:
The Ruby Mod is arguably the hardest hitting, single tube mechanical hybrid currently available with thousands of possible personal permutations.

Fat Dragon Tip (Accessory):
[ Note the Bore Diameter of the Fat Dragon Tip ]
• May reduce rate of coil carbonization by improving heat dissipation.
• Greater draw volume for increased airflow rate and vapor production.
• Friction fit for the Ruby/K24/K22. 17.5mm OD. 13mm to 11.25mm tapering ID.
• Improved (visual) juice capacity feedback reduces the prospect of overdripping.
•
Fat Dragon Tip available in assorted colors direct from Kennedy Enterprises.
• Copper | Brass | Stainless Steel | Black Delrin | Colored Acrylic
• Radiused and more comfortable to vape than the standard tip (YMMV).
Slam Cap 24 (Accessory):
[ Made in the USA: Ruby Red Swirl | White | Dark Blue Swirl ]
• Domed Chamber
• 24mm Outside Diameter
• 22mm Height w/o Drip Tip
• Dragon Cap = 24.5mm w/o Drip Tip
• Virtually No Loss in Vapor Production
• Standard K24 Drip Tips Extend into Chamber
• Use K24 Drip Tips w/ 4.5mm Neck
• Shorter Chamber = Reduced Air-to-Vapor Ratio
• Reduced Air-toVapor Ratio = Condensed Vapor
• Condensed Vapor = Greater Potential Flavor
• Available in Cu/Brass/SS/Black Cerakote
• 1 x AS568-112N70 O-ring
• Secures Friction Fit Drip Tip
• CNC Engraved Branding
• Limited Production Part

tl;dr: The Ruby Mod is a hard-hitting, true hybrid mechanical device which satisfies both flavor and cloud chasers with its improved K24 deck and its ability to suit various vaping styles with an impressive array of top cap and drip tip options.
