(15) Inexpensive Mechanical Mod/RDA Setup

Published by Baditude in the blog Baditude's blog. Views: 3854

Many vapers are asking the best way to get into dripping on a mechanical mod and RBA without breaking their bank account. I've carefully chosen the following recommendations based on my experience which can provide an inexpensive quality setup, and added suggestions for the tools & supplies needed to make coils.

The Silver Bullet and IGO-W were my first mech mod and first rebuildable drip atomizer. I've been using Silver Bullets for nearly 3 years. My son is now using my IGO-W on another Silver Bullet. I'm currently using a dual microcoil build @ 0.6 ohms with Rayon (cellucotton) wick in an authentic gun metal Patriot RDA on a black silver-vein Silver Bullet (see pic below).



Silver Bullet mechanical mod from AltSmoke. $85
  • A classic that's been around for years and continues to be a staple in many vapers' collection.
  • USA made, so in the unlikely event should it need repair you can just send it to AltSmoke.
  • Safer and more natural side fire button with a wired switch; recessed button prevents accidental autofiring unlike a bottom-fire button. Battery ventilation via the specially designed fire button; batteries usually vent at the battery top, not the bottom where most other mechanical mods have their ventilation holes.
  • Lightweight yet durable, its milled from aircraft-grade aluminum block.
  • Available in many colors.
  • Kick extension sleeve available to use with the 18650 IMR battery should you decide to use a Kick.
  • A fully mechanical Silver Bullet is also available.

IGO-W rebuildable drip atomizer. $17
An inexpensive first RDA with three posts for single or dual coils. Does not come with a drip tip. The stock holes in the cap will need to be drilled out to be larger at some point for improved air flow.

Sony VTC4 30 amp IMR/hybrid batteries. $9-$13 each
Best, safest, and most versatile battery on the market. Don't skimp on batteries, they are the most important gear in your setup and potentially the most dangerous. Use Samsung 1865025R 2500mAh 20 amp if unable to find Sony's in stock.

Sony VTC4 2100mAh 30 amp CDR

Battery charger:
Xtar, Nitecore Intellicharger, Pila, or Efest LUC. $17 - $50 depending on features.

You'll need a digital multimeter, or an ohm reader and a 510 voltage meter, to measure coil resistance and battery voltage.

Precision Screwdriver Set. $7
Used to wrap your coils around and tighten your RDA post screws. Screwdriver bases have the diameter clearly marked on them in mm.

Stainless Steel Tweezer. $7
Used to compress the coil loops to make a compressed coils. Also helpful to tease the wick through the coil.

Mini Butane Torch. $8 (optional - not everyone anneals their Kanthal wire)
Used to anneal Kanthal wire. Don't forget fuel for the torch.

Scissors, wire cutter, or nail clipper to cut wire and wicks.

Kanthal wire: $8
Available in different thicknesses (gauges). 28 gauge is usually recommended for novices.

Organic cotton balls, cellucotton (rayon) , Ecowool, or silica wick.
I strongly recommend building a single microcoil at 1.0 ohm for your first couple of builds. Once you get that down, you can learn to build dual coils and use lower resistance. Baby steps. K.I.S.S. (Keep It Simple, Stupid)

Information Resources for Your First RBA - please read this thoroughly before you begin to rebuild.

Ohm's Law Calculator - Insure that your measured coil resistance will not pull more amps than your battery's continuous amp rating. Always use 4.2 volts as the voltage (fully charged battery). How to use an Ohm's Law calculator.

Coil Wrapping Calculator - Type in the appropriate info in the drop down menus and learn how many wraps for a particular resistance coil. Provides a graphic of how the finished coil should look.

Ohm's Law for Dummies - Learn to understand voltage, resistance, and amps here as it applies to vaping.
