Should I Buy a CNC Router?
The most dangerous tool in any workshop is not the saw. It is the exciting new machine catalogue.
There is a particular danger in running a workshop full of useful equipment. Every new machine begins to look less like a luxury and more like the missing piece of the puzzle.
We already have a laser cutter, 3D printer, sewing and embroidery machines, printing equipment, tools for making teaching resources, and enough half-finished ideas to keep a small engineering department busy until retirement — or possibly beyond it. So the question is not, “Would a CNC router be interesting?” Of course it would. The real question is much more serious:
Would a CNC router solve real problems for Philip M Russell Ltd, or would it simply create a new and expensive collection of problems?
That is the question I have been trying to answer.
The Temptation of the Next Machine
Anyone who likes making things knows this feeling.
You start with a simple job: perhaps a sign, a jig, a bracket, a teaching aid, a boat part, or a template. Then you find yourself thinking, “This would be easier if only we had…”
That sentence is dangerous.
It can lead to sensible investment. It can also lead to a large machine arriving in the workshop, followed by six months of learning software, buying accessories, improving dust extraction, reorganising benches, watching tutorials, breaking cutter bits and muttering phrases that should not appear on a company blog.
A CNC router is not just a machine. It is a commitment.
It needs space, software, tooling, extraction, maintenance, materials, time and a stream of suitable projects to justify its existence. But if those projects are real, it could be a very useful addition to the workshop.
What Can a CNC Router Do That a Laser Cutter Cannot?
Our laser cutter is already a very useful tool. It can cut and engrave thin materials with great accuracy. It is excellent for acrylic, plywood, card, labels, signs, templates, display pieces, engraved teaching resources and prototype parts.
But a laser cutter has limits.
It does not like cutting thick timber. It burns edges. It cannot easily carve three-dimensional shapes. It is not designed to remove large amounts of material. It cannot machine a smooth curve into a solid wooden panel, cut a recess to a precise depth, or shape a mould.
A CNC router works differently. Instead of burning through material with a laser beam, it uses a rotating cutter to remove material. That means it can cut, drill, pocket, carve and shape much thicker materials.
A laser cutter is brilliant for flat, thin, precise work.
A CNC router is more like a computer-controlled carpenter, pattern maker and workshop assistant.
Used well, it could open up new possibilities.
Used badly, it could become an extremely accurate way of making expensive firewood.
Cutting Thicker Wood, Panels, Templates and Moulds
One of the most attractive uses of a CNC router would be cutting thicker panels and timber components.
For example, it could be used to make:
- shaped wooden panels
- accurate plywood templates
- curved formers
- moulds for GRP or composite work
- replacement backing plates
- workshop jigs
- drilling templates
- storage racks
- display boards
- large signs
- teaching apparatus frames
The advantage is repeatability. Once a design has been created, the same part can be produced again with consistent accuracy.
That matters in a workshop where one-off prototypes often turn into “Could we make three more of those?” projects.
With a CNC router, a design made for one science practical, one camera mount, one jig or one boat part could be improved and repeated rather than reinvented each time.
Possible Boat Restoration Uses
The Champagne restoration project makes the CNC router idea particularly tempting.
Classic boats are full of awkward shapes. They have curves, angles, fittings, backing plates, supports, templates and pieces of timber that rarely come in standard sizes from a DIY store.
For Champagne, a CNC router might help with:
- making templates for replacement wooden parts
- cutting shaped backing plates
- producing neat signage or name boards
- making supports for storage and transport
- creating camera mounts for filming the restoration
- cutting accurate panels for temporary covers or workshop aids
- making patterns for parts before committing to expensive material
- producing jigs to help with sanding, drilling or assembly
It could also be useful for other sailing-related work: trophy bases, event signage, engraved plaques, boat display stands, sponsor boards, or even merchandise connected to the A-Rater project.
But here we need to be careful.
A CNC router would not magically restore Champagne. It would not varnish the wood, repair rigging, fix loose fittings or make us better sailors. It might help with some jobs, but only if those jobs are clearly identified.
There is a big difference between buying a machine because we have a use for it and buying one because we hope uses will appear later.
With boats, uses always appear later. Unfortunately, so do bills.
Science Equipment Manufacture
The CNC router might be even more useful in the education side of Philip M Russell Ltd.
A lot of our teaching is practical. We use experiments, demonstrations, models and visual aids to help students understand science rather than just memorise it.
There are many possible classroom and laboratory uses for a CNC router:
- making wooden frames for apparatus
- cutting baseboards for practical equipment
- producing holders for sensors
- creating models of biological structures
- making physics demonstration parts
- producing microscope slide storage trays
- cutting labelled revision boards
- creating equipment racks
- making custom mounts for cameras and lights
- producing repeatable parts for experiment kits
One particularly useful area would be making strong, tidy, repeatable components for custom practical equipment. A 3D printer is excellent for small plastic parts, and the laser cutter is excellent for thin sheet material, but there are times when a thicker, stronger, machined wooden or plastic part is more appropriate.
A CNC router could fill that gap.
For example, if we were building a model of a leaf structure, a flower model that comes apart in layers, a physics apparatus support, or a custom jig for a required practical, the router could make strong and accurate parts that look professional and survive student use.
That last point matters.
Students are wonderful, but any piece of equipment used in teaching must be designed on the assumption that someone will eventually tighten the wrong screw, lean on the wrong part, or ask, “Was this meant to come off?”
Signage, Jigs and Workshop Parts
One of the less glamorous but most important uses of workshop equipment is making the workshop itself work better.
A CNC router could help make:
- storage racks for tools and materials
- labelled drawers and holders
- camera equipment mounts
- cable guides
- safety signs
- wall panels
- machine templates
- drilling guides
- cutting jigs
- repeatable production fixtures
Jigs are not exciting to most people, but they are often what turns a slow, fiddly job into a reliable process.
A good jig saves time every time it is used. It also reduces mistakes. In teaching equipment manufacture, boat restoration and video production, that could be valuable.
The laser cutter can make some jigs, but a CNC router could make thicker, stronger versions. That could be particularly useful for anything that needs to be clamped, drilled, screwed, sanded or used repeatedly.
The Costs Nobody Mentions in the Exciting Brochure
The cost of a CNC router is not just the price of the CNC router.
That is where many workshop dreams become slightly more complicated.
A realistic budget has to include:
The Machine
There is a wide range of CNC routers, from small desktop machines to larger workshop models capable of cutting full sheets. A small machine may be cheaper and easier to house, but may not handle the size of projects we actually want to make.
A larger machine would be more useful, but also more expensive, heavier, louder and harder to fit into the workshop.
Cutter Bits
Router bits are consumables. They wear, break and need replacing. Different materials and jobs need different cutters.
There would need to be a sensible starter set, plus replacements for the ones I will inevitably break while learning. This is not pessimism. This is experience.
Dust Extraction
A CNC router makes dust. Lots of dust.
Unlike the laser cutter, which has smoke extraction, a router produces physical chips and fine dust. Cutting MDF, plywood or hardwood without proper extraction would quickly become unpleasant and possibly unsafe.
Proper dust extraction is not optional. It is part of the machine.
Software
The machine needs design and toolpath software. There may be free or low-cost options, but professional use usually benefits from proper software and a proper workflow.
That means learning time as well as software cost.
Space
A CNC router needs more than the footprint of the machine. It needs working space around it, somewhere for materials, somewhere for extraction, and enough room to load and unload safely.
In any workshop, space is the one thing you never have as much of as you thought you did.
Noise
Routers are not quiet. This matters if the machine is used near teaching spaces, filming areas, or at times when noise would be disruptive.
A laser cutter hums and extracts. A CNC router announces itself.
Time
The biggest hidden cost is time.
There is time to learn the software. Time to test materials. Time to set up jobs. Time to clamp work properly. Time to clean up. Time to troubleshoot. Time to remake the part you confidently cut 3mm too small.
The machine may save time in the long run, but it will not save time on day one.
Would It Complement the Existing Equipment?
This is the central point.
A CNC router would not replace the laser cutter, 3D printer or other equipment. It would complement them.
The laser cutter is ideal for precise flat work, engraving, labels, thin sheet material and quick prototypes.
The 3D printer is excellent for small complex shapes, brackets, holders and prototypes.
The CNC router would sit between those tools and traditional woodworking. It would be useful for larger, stronger, thicker, more structural parts.
In a well-planned workshop, the workflow might look like this:
- design the part on the computer
- prototype small details on the 3D printer
- cut thin templates or labels on the laser cutter
- machine stronger final parts on the CNC router
- assemble and finish by hand
That sounds powerful.
It also sounds like another system to learn properly.
The Danger of Buying Possibility Instead of Productivity
This is where I have to be honest with myself.
It is very easy to buy possibility.
A CNC router represents possibility. It says: “Imagine what we could make.”
But a business has to think about productivity. It must ask: “What will we actually make, how often will we make it, and will it justify the cost?”
There are three types of workshop purchase:
- Essential tools — things needed to do regular work.
- Useful tools — things that save time, improve quality or open up realistic new services.
- Fantasy tools — things bought because they are exciting, then mainly used as expensive shelves.
The aim is to make sure a CNC router would fall into category two, not category three.
Before buying one, I need a proper project list.
Not vague ideas. Not “that might be useful one day.” A real list of jobs.
A Sensible Test Before Buying
Before buying a CNC router, it would make sense to create a trial list of potential projects and ask some practical questions.
For each possible project:
- What exactly would we make?
- What material would it use?
- What size would it be?
- Could the laser cutter already do it?
- Could the 3D printer already do it?
- Could it be made more easily by hand?
- Would we need to make it more than once?
- Would it save time?
- Would it improve quality?
- Would someone pay for it, or would it support the company’s work?
Possible test projects could include:
- a set of science apparatus baseboards
- a boat name plaque for Champagne
- a camera mount for sailing filming
- a storage rack for the workshop
- a template for restoration work
- a teaching model with removable layers
- a set of branded signs for the classroom or lab
- a jig for repeat drilling or assembly
If those projects look genuinely useful, the case for a CNC router becomes stronger.
If the list feels forced, the answer may be “not yet.”
Personal Reflection: The Joy and Trap of Making Things
One of the best things about Philip M Russell Ltd is that the business does not sit neatly in one box.
We teach science. We make videos. We build equipment. We restore boats. We create learning resources. We design practical experiments. We produce social media. We photograph, film, edit, print, engrave, repair and occasionally wonder why the workshop floor has disappeared under another pile of useful things.
A CNC router fits that world very well.
It is the sort of machine that could support teaching, filming, restoration, signage and product development. It could help turn ideas into physical objects. It could allow us to make stronger prototypes and more professional parts.
But that is also why the decision needs care.
Because when a machine could be used for everything, it is easy to forget to ask whether it will actually be used for enough things.
The excitement is real. The possibilities are real. But so are the costs, dust, noise, learning curve and space requirements.
So, Should We Buy One?
The honest answer is: possibly — but not just because it would be exciting.
A CNC router could be a very sensible addition to the workshop if it clearly complements the existing laser cutter, 3D printer and production equipment. It could help with boat restoration, science apparatus manufacture, signage, jigs, workshop improvements and prototype development.
But the decision should be based on real jobs, not machine envy.
The next step is not to press “buy now.” The next step is to create a proper list of projects, estimate the materials, check the workshop space, research dust extraction, understand the software, and decide what size of machine would actually be useful.
The key question remains:
Would a CNC router solve real problems, or would it simply create new ones?
If it solves enough real problems, then it may earn its place in the workshop.
If not, the most sensible CNC router is the one in the catalogue — admired from a safe distance, with the credit card firmly out of reach.
