How to Install an Ugly Drum Smoker in 8 Easy Instructions

You ordered the parts. The boxes showed up. Now you’re standing in the garage staring at a drum and a pile of stainless steel.

Exciting? Yes.

 A little intimidating? Also yes.

Most ugly drum smoker instructions walk through one kit at a time. There’s a sheet for the hinge. Another for the vents. Something else for the basket. That works, but it doesn’t always show the full picture of how everything comes together during a UDS build.

Technically, you can install many of these components in different orders. This guide simply lays out one clean, logical path for building an ugly drum smoker without second-guessing yourself along the way.

If you’re wondering how to build a UDS smoker step by step, these seven instructions will walk you through it.

What Are the 8 Steps to Install an Ugly Drum Smoker?

Individual ugly drum smoker instructions explain each kit on its own. What they don’t always show is how the full UDS build comes together as a complete install.

Below is a practical breakdown of the major phases involved in building an ugly drum smoker, grouped into seven clear steps.

1. Prep Your Drum and Workspace

2. Install Airflow Components

3. Build the Fire System

4. Install the Charcoal Chute (If Applicable)

5. Install Cooking Components

6. Install Lid Hardware

7. Perform Final Checks

8. Complete Your First Burn

1. Prep Your Drum and Workspace

Before drilling anything, take a few minutes to set up correctly. Most issues during a UDS build trace back to rushed layout.

Start with the drum:

• Confirm it’s clean and empty

• Set it on a flat, stable surface

• Verify you’re working with a standard 55-gallon drum if following typical ugly drum smoker instructions

Gather your tools:

• Drill with step bit and 5/16” bit

• Measuring tape and marker

• 7/16” wrench or socket

• Adjustable wrench or pliers

• Cutting tool if installing a charcoal chute

Lay out all kits and separate hardware by component. It keeps the install organized once drilling begins.

Before making any holes, mark the major locations:

• Inlet vents: about 2 inches from the bottom

• Grate supports: roughly 8 inches down from the top lip

• Charcoal chute cutout: 13.75 inches up from the bottom

Double-check spacing and clearance between components. Once holes are drilled, adjustments are limited.

2. Install Airflow Components

Airflow controls temperature during your UDS build, so install these components before adding anything inside the drum.

Inlet Vent

Mount the inlet vent approximately 2 inches from the bottom of the drum.

• Mark and drill the required holes

• If applicable, drill three 1-inch airflow openings

• Secure the vent assembly and confirm the door slides freely before fully tightening

Proper placement keeps airflow consistent and prevents ash interference.

Exhaust Vent

Install the exhaust vent on the lid.

• Mark and drill the 5/16-inch center pivot hole

• Drill four surrounding vent holes, typically between 5/8 inch and 3/4 inch

• Attach the vent and confirm it rotates smoothly

Before moving on, check that both inlet and exhaust vents open and close cleanly. Air should move freely through the drum.

3. Build the Fire System

With airflow installed, move to the internal components that manage heat.

Assemble the Charcoal Basket

Follow your kit instructions to:

• Insert the bottom into the side slots

• Lock tabs in place using pliers

• Attach the ash pan and secure all tabs fully

Make sure the basket sits flat and stable. A loose tab now can cause shifting later.

4. Install the Charcoal Chute (If Applicable)

If you’re installing a charcoal chute, this is the only step that requires cutting into the drum. Measure carefully before drilling or cutting.

If you purchased a pre-drilled Smokin’ Ugly kit, the chute opening may already be completed and you can move directly to assembly.

Mark and Cut the Opening

The bottom of the chute cutout should be 13.75 inches up from the bottom of the drum.

• Mark the cutout using the chute frame as a guide

• Drill pilot holes in the corners

• Cut the opening slowly with a jigsaw or tin snips

• Smooth any sharp edges

Assemble and Mount the Chute

Before attaching it to the drum:

• Insert the side panels into the chute slots and twist the tabs to lock them

• Install the gasket evenly around the bezel

• Position the chute in the opening and secure the hardware

Check that the door opens and closes cleanly and sits flush against the drum before tightening everything fully.

Once installed, the chute allows you to add fuel without removing the lid, which helps maintain temperature during longer cooks.

5. Install Cooking Components

With airflow and the fire system in place, install the components that support your food.

Most UDS builds position the cooking grate about 8 inches down from the top lip of the drum.

• Mark five evenly spaced holes

• Drill 5/16-inch openings and install the support bolts

Before tightening fully, confirm the bolts sit level so the grate won’t rock during use.

Set the cooking grate on the bolts and check that it rests flat.

If you’re adding utensil hooks, twist them outward to about 90 degrees, mount them at your chosen height, and tighten securely.

Once everything is aligned and stable, the cooking surface is ready.

Install the Heat Deflector or Water Pan Holder

If your UDS build includes a heat deflector:

• Insert the mounting legs into the slotted holes

• Rotate them down until locked in place

• Set the shelf onto the legs and secure with cotter pins

Position the assembly so it sits level above the charcoal basket.

This setup directs heat evenly upward and helps regulate temperature during your cook.

6. Install Lid Hardware

With the drum body complete, install the lid components.

Start with the hinge. Position it tight against the lid and drum before marking any holes.

• Mark all mounting holes before drilling

• Drill 5/16-inch holes

• Mount the lid side first, then secure the drum bracket

• Adjust spring tension with the lid fully open

Test the lid movement before tightening everything completely. It should open smoothly and hold position without dropping.

Next, install the latch and handle.

• Mark and drill the mounting holes

• Confirm the latch aligns with the handle hook

• Tighten once you’re confident it disengages cleanly

Open and close the lid several times to confirm smooth movement and proper alignment.

7. Perform Final Build Inspection

Before lighting anything, inspect the full UDS build one last time.

Walk through this checklist:

All bolts and hardware are tightened

Lid opens smoothly and holds position

Hinge tension feels balanced

Latch engages and releases cleanly

Inlet vent slides freely

Exhaust vent rotates without scraping

Charcoal basket sits flat

Cooking grate is level

Test the lid, vents, and grate for smooth movement and stability. Nothing should feel loose or restricted.

If everything moves cleanly and feels solid, the installation is complete.

8. Complete Your First Burn

A first burn is the initial high-heat run of your smoker without food. It removes residue from drilling and handling and begins seasoning the inside of the drum.

Before cooking anything, run through this process:

• Fill the charcoal basket with lump charcoal or your preferred fuel

• Open the inlet and exhaust vents fully

• Light the charcoal and allow the smoker to come up to temperature

• Let it run hot for several hours

• Allow the drum to cool completely before closing the vents

During this burn, you may notice smoke from oils or light surface residue inside the drum. That’s normal. The heat cleans the interior and helps create the base layer that develops over time with use.

After the smoker cools, check that vents still move freely and hardware remains tight. Once everything looks good, your UDS build is ready for its first cook.

Ugly Drum Smoker Instructions Made Simple

Clear ugly drum smoker instructions keep your UDS build focused and manageable. By working through each phase methodically, you’ve assembled a smoker that’s aligned, stable, and ready for heat.

With installation complete and the first burn finished, your drum is seasoned and prepared for its first real cook. From here, it’s all about dialing in airflow and enjoying the process.
