Steampunk MOC: Gears, Copper Pipes and a Retro Airship
The short version: this steampunk MOC is built around a retro airship, uses roughly 3,900 pieces, and finishes at about 65 cm long and 48 cm tall. At two hours a day it takes around 14 hours to complete, and the total budget lands near 780 CNY. The look comes from heavy use of copper, dark brown and dark gold parts to create an aged, oxidized finish, with gears and copper piping running through the whole ship. Turn the main gear and the propeller at the tail spins with it. The instructions are hosted on brickplan, and the parts list is split by mechanical module, which makes it a good fit for intermediate builders who like the steampunk style.
Step 1: Stand up the hull frame first
Start the hull on a 44x28 stud baseplate. Build the streamlined body from curved slope and wedge pieces on both sides, and keep the bottom flat so the model sits stably on a shelf. Inside the hull, lay down a layer of structural framing first, leave a cavity in the middle for the gear bay, and reserve the connection points on top for the gondola mount. The hull is mainly dark brown and dark gold, with copper pieces dotted around as rivet detailing. This step uses about 1,300 pieces.
Step 2: Install the gear bay and hook up the propeller
Fit the gear bay with a set of gears in different sizes. The main gear measures about 6 cm across and connects through a cross axle to the three-blade propeller at the tail. Turning the handle on the main gear sends power through a two-stage reduction to the propeller — the rotation is slow, but the mechanical feel is exactly the point. Build the gear bay cover as an openable panel so you can watch the teeth mesh inside. This module uses about 800 pieces.
Step 3: Run the copper pipes and build the boiler room
Assemble the copper lines from copper curved and straight pipe pieces, running from both sides of the hull down to the boiler room at the bottom, with pressure gauges and valves at the pipe ends. The boiler room is a semi-open structure holding a boiler and a coal scuttle, with a chimney rising through the deck. Clamp pieces secure the piping to the hull at intervals, and leave a gentle curve in each run rather than forcing the pieces straight. This module uses about 900 pieces.
Step 4: Gondola, balloon, then the weathering pass
The gondola hangs below the hull on chain links, with a pilot minifigure and instrument panel inside. The retro balloon on top is built from brown fabric-textured pieces into an oval, with custom stickers on the side for a patchwork effect. Finish with a small number of gray pieces along the hull edges to suggest wear and scuffs, and the aged look comes together. When everything is assembled, check your parts against the mechanical module list on the brickplan instruction page.
FAQ
Q: Where can I download the steampunk MOC instructions?
A: Search the steampunk category on the brickplan site to find this airship plan. The page offers high-resolution step-by-step views and a parts list broken down by mechanical module, and the PDF is free to download after registering.
Q: Is the gear linkage hard to install?
A: Medium difficulty. The key is to fix the main gear's position first as shown in the instructions, then install the driven gears one stage at a time, adjusting spacing with axle bushes. The plan marks the size and position of every gear stage clearly, so if you follow the order nothing will jam.
Q: How long does the whole build take?
A: About 14 hours at two to three hours a day. The hull and gear bay are the biggest time sinks at roughly 6 hours, the copper pipe routing takes about 3 hours, and the rest goes to the gondola and weathering details.
Q: Are copper-colored parts easy to buy?
A: Yes. Copper, dark brown and dark gold are all common colors, and domestic parts makers such as Gobricks keep them in stock. The full parts lot costs around 780 CNY, with copper pipe and gear pieces accounting for about 260 CNY of that, and you can buy in batches following the brickplan list.
Q: How do I get the weathered effect?
A: No spray paint needed. Use small gray and dark brown pieces along the hull edges as patches and rust marks, or wipe surfaces lightly with a soft cloth dampened with alcohol for a natural worn look — it won't damage the parts.
