A manual stringer router built for the bespoke stair maker — gives you repeatable, accurate housings in straight and curved stringers without the setup overhead of a full CNC machine. A practical way to bring more of your stair machining in-house.
Typically chosen by
Joinery workshops producing bespoke residential staircases to individual drawings
Stair specialists looking to bring more of the machining process in-house rather than outsourcing
Smaller manufacturers wanting a stepping stone into stair automation before committing to a full CNC setup
All axes are manually controlled with precision guides and lockable stops — faster and more consistent than hand-routing, without the programming overhead of a full CNC machine.

Application
Bespoke stair making — straight and curved stringers, residential and commercial
Working envelope — including maximum stringer length and housing depth — varies by configuration. Talk to IWM before specifying to ensure the machine suits your typical staircase sizes.
Spindle Power
Contact IWM for confirmation
Confirm motor power with IWM — this will determine whether a dedicated electrical circuit is required in your workshop.
Electrical Supply
Contact IWM for confirmation
Confirm phase and amperage with IWM before ordering — three-phase supply is not available in all workshop premises.
Machine Dimensions (footprint)
Contact IWM for confirmation
Allow additional clearance beyond the machine footprint for full stringer length feed-in and operator movement on both sides.
Machine Weight
Contact IWM for confirmation
Dust Extraction Connection
Contact IWM for confirmation
Confirm extraction port diameter with IWM to ensure compatibility with your existing dust extraction system before installation.
Choose the Pouwels DEF-50 Stair Making Machine if...
You're producing bespoke staircases regularly and hand-routing is creating bottlenecks or inconsistency
You want dedicated stair machining capability without the cost and complexity of a full CNC installation
Your work involves repeating similar profiles across multiple projects where a manual router with lockable stops gives real time savings
You're a smaller workshop that needs a practical, lower-overhead route into stair automation
Consider an alternate model if...
Your stair output is occasional or low-volume — in which case IWM Stair Cramps and hand methods may be more cost-effective to discuss
You're producing high-volume or highly complex staircases where a US Concepts INC. specialist CNC stair machine may offer better throughput and flexibility
You need a fully integrated software-driven workflow — Pouwels' own CNC range with dedicated stair software may be the more appropriate step up
You primarily need clamping and assembly support rather than machining — the IWM 4 Piston Hydraulic Stair Cramps address a different part of the stair-making process
