Axminster AT260SPT Planer-Thicknesser Induction
Some of the tools at the Hackspace are potentially hazardous to use, for these tools members are required to have an induction before they can use them. Inductions provide the most basic information on how to safely and effectively use the simpler functions of the tools, we appreciate that some members may have professional experience on some of these tools and in this case please tell your induction provider and the induction may be very reduced and just cover any risks or procedures specific to rLab. Some tools have multiple levels of induction in order to cover more advanced uses of that tool without making the basic induction take too long, higher induction levels will introduce some of the more advanced features of the tools but as with all inductions are only intended to provide basic information on the capabilities of the tools and how to use them safely. Some members of rLab may be willing to offer more detailed tuition beyond basic induction level or offer guided practice sessions in exchange for beer money or assistance on their own projects.
For all tools you are only required to take level-1 induction before use, after that you may perform any task that you feel confident you can do safely, higher levels of induction may be useful to you in performing more advanced operations but are not required before doing tasks covered in them so long as you're confident of your ability to handle those tasks without risk to yourself, others, or the tool.
PLEASE NOTE : All induction providers are volunteers who are providing inductions to the best of their ability but are NOT qualified instructors. Inductions are provided on a best-effort basis but you and you alone are responsible for your safety while using the tools and for satisfying yourself that you can operate the tools safely. There are professional training courses available from various providers in Reading and the surrounding area if you feel they are appropriate for the level of work you intend to undertake. Reading these notes is NOT a substitute for an in-person induction.
Note for wiki editors : Please do not edit induction pages unless you are one of of the people that gives that induction
Introduction[edit]
The planer thicknesser is an Axminster AT260SPT. This is a combination machine, which can be configured to work as a surface planer (for the flattening of faces and edges of wood), and as a thickness planer, to dimension wood that has already been surfaced (“jointed”) on one face and/or edge.
Both modes of operation involve passing the wood over a circular cutter block which holds 44 tungsten carbide knives.

Materials |
The planer thicknesser is designed to work almost exclusively with wood, and additionally, it’s effective operation depends on the direction of the wood grain as it is passed over the cutter block. It is not designed to work across the grain of the wood, or on the end grain of the wood, in either of the surface planer or thickness planer modes. For this reason it's not well suited to composite materials like plywood or MDF, it is not possible to plane the face of plywood, as the alternating grain direction in subsequent layers results in chips that are too large to evacuate, which clog the machine. It is possible to plane the edge of plywood, but this is quite hard on the knives, and in most applications the table saw would make more sense. There are some firm modelling foams which can be processed by the planer thicknesser. This should be done with extra care, as they produce long chips which are difficult to evacuate and are known to clog the machine very rapidly, extremely frequent (every couple of passes) checking of the machine and extraction hose will be needed when using foams The material must be free of any metal - screws, staples, nails etc. These will damage the blades. This is a special concern when working with reclaimed timber, also be aware that painted surfaces tend to wear the cutters faster so although they CAN be cut, please limit that as much as possible. |
What stuff can be used on this machine |
General Safety |
Never pass your hands over the exposed cutter block. Never push stock directly down into the cutter block. Never manipulate the cutter block or knives with the machine plugged in. There are no interlocks to prevent the machine starting while it is being adjusted. Long pieces of wood will require two people to handle them with this machine. The HSE document on safe working practices for surface planning can be found here. |

Surface Planing / Jointing[edit]
Topic | Detailed contents | Rationale |
---|---|---|
Introduction |
Surface planning (Jointing) is the process of machining a rough wooden surface to make it accurately flat and smooth, it's often done as a first step towards making an accurate angle or to ensure a block of wood is parallel across it's sides. The procedure for surface planning involves passing stock over the in-feed table, into the cutter block, and out over the out-feed table. The out-feed table is set level with the peak of the cutting circle, and the in-feed table is set somewhat lower than the out-feed table. Therefore, as stock passes over the in-feed table and through to the out-feed table, the cutter head removes scallops of material, with repeated passes serving to smooth and flatten a surface of the stock. As passes are repeated then the surface is progressively leveled out and imperfections removed. A fence should be attached to the machine when planing, to provide a reference surface for jointing two adjacent surfaces of the stock to some user defined reference angle (normally 90 degrees). Here, a typical process would be to flatten a face, and then, using this flattened face against the fence, flatten an edge at 90 degrees to the face. From here the thicknesser and table saw can be used to give stock that has 4 sides which are either square or parallel to each other. There are some limiting dimensions to consider: You should not joint pieces less than 250mm long and 5mm thick. The maximum width is 260mm. |

Thicknessing[edit]
Topic | Detailed contents | Rationale |
---|---|---|
Introduction |
Thicknessing will take a block of wood with one face already made flat by planning and make the opposing face flat and parallel to the other. Thicknessing is simpler than surface planing, as the machine does more of the work. In this mode, stock is passed underneath the cutter block and feeder generally pulls the stock through for you. In this mode, stock is passed through the machine in the opposite direction to surface planing (so that it still goes against the rotation of the knives).
