A surface planer used for generating a smooth and flat surface on a piece of timber, often starting from warped or rough-sawn timber. It is often followed in use by a thickness planer which produces a parallel surface on the opposite face of the board. Note - in the USA a surface planer is often called a jointer - there the word 'planer' confusingly often refers to a thickness planer

This planer has a maximum cutting width of 230mm and the overall table length is approx. 1300mm

The blades for this machine are very expensive and time consuming to sharpen (we have to take them to an external workshop with paid access) - please do not do anything that could damage the cutting edges (see below). If you do notice damage to the blades, please notify the maintainers at the earliest opportunity

Specific rules for this machine:

• Do not adjust the setting of the blades within the cutter head or the height of the outfeed table - setting these is a difficult and time consuming task carried out by the maintainers during a blade change
• Adjusting the fence angle (to produce bevelled edges) is fine, but please set accurately back to 90° afterwards
• Do not use any reclaimed wood (in particular pallet wood) on this machine - even tiny fragments of nails, screws or staples left in the wood will chip the blades
• Try not to plane bark - it usually contains traces of soil or grit which wear the teeth quickly. Use a handheld electric planer to remove the bulk of any bark before taking to the planer
• If your hands need to go anywhere near the blade (particularly when face-planing thin stock) always use a push stick or preferably, a pair of planer paddles
• Always use the planer with the guard installed

On the left hand side of the machine is a non-functioning slot mortising attachment. This is designed to act as a horizontal router with a bit held in the end of the rotating cutter drum. Significant work would be needed to bring this into operation, so for now please do not attempt to use it. Anyone who wants to take on the task of getting it running is more than welcome, please speak to the maintainers

This machine requires training and is ACNode protected. To arrange training, ask in the 'lhs-induction-requests' channel of our Discord Server

For beginners better to start with Triton Thickness Planer [1] and get familiar with wood working.

Information for Maintainers

The blade size for this machine is 9.1/4" x 1.1/8" x 5/32". This is not a stock size for modern planer blades, so larger blades may need to be purchased and ground down. 'NLS Tools' were the last supplier we used, at around £60 per pair of blades. We currently have 2 pairs of blades - the intention being we can sharpen one while the other is fitted, to enable quick changeovers The blades are best sharpened on a surface grinder (the space does not have one so this needs to be done externally - speak to Toby Molyneux or Dean Forbes for information). Two machined jig blocks are available to hold the blades for sharpening - these can be found in the woodshop maintainers cupboard along with the spare pair of blades

This planer was not originally fitted with any kind of blade guard, so we have added a home made one operated by a counterweight. The rope and the pivoting bearing should be lightly greased periodically

The original bolts and fittings on the planer are Whitworth (BSW) threads. Any new parts added on (e.g. blade guard) use metric hardware - if in doubt test. If new bolts are ever installed in the cutter head, note that they will need to be reduced in height or they may stick out further than the blades

Risk Assessment - Wood Planers

This risk assessment is intended to provide guidance on the risk associated with the above equipment and activities in normal use. Please also check general risk assessments for the space as a whole. Any discrepancies, errors or concerns should be raised with the document maintainers or trustees - do not edit this assessment directly. For responsible persons and last update, see 'version log' of the assessment page.

Activity

Use of handheld or stationary wood planing equipment such as handheld planers, bench planers (aka jointers) or thickness planers

Incompetent user	User, bystander	HIGH	Members must not use tools that they are not competent to use. Members must challenge use that they believe is dangerous. Members must read the user manual for this tool. Members must read the risk assessment before using a tool. Members will be advised during induction which tools they will need supervision or an induction to use. Only authorised members will complete maintenance and calibration tasks.	LOW	MED
Contact with rotary knives	User	HIGH	Do not put hands within 10cm of blade. Do not push workpiece over blade with hands. Use a push block to push workpiece over cutting area. Use guard to cover unused cutting area. Use guard to cover entire cutting area when thicknesser is being used. Do not insert hands into thicknesser when machine is plugged in. Planer should be turned off immediately after use.	MEDIUM	MED
Drawing in (being pulled into the drum)	User	HIGH	User of the thicknesser/planer should not wear gloves, ties, scarves, or other long flowy clothing that could get pulled into the blade. Do not move hands past the blade. Do not use the machine on short stock.	LOW	MED
Dust (inhalation, fire, explosion)	User, bystander	MEDIUM	Stationary machines must be used with the workshop dust extractor. An extraction hose must be attached to the machine’s extraction hood, which must be positioned appropriately for use with the thicknesser or planer. Maintenance must include the cleaning of dust from within the unit housing where accessible. Check the extraction hood periodically for blockages. A respirator or mask should be used whilst operating this tool for prolonged periods.	LOW	LOW
