===Maintenance and Cleaning Instruction===
Ensure all the internal mechanics are cleaned once a month using the brush and the vacuum cleaner. If you are not sure how to do it ask the team.
{{:Risk Assessment/ Bandsaws}}
= Induction Script =
The first stage of any induction is to read and familiarise with the Risk Assessment and PPE requirements
===What is a BandSaw For===
Cutting wood and plastic
* Straight cuts in thick material (within limits, generally 6"/150mm without checking)
* Stopped cuts eg tenons
* Small material you can't take near the mitre or table saws
* Gentle curves
* Generally, safer than circular blades (but not always 'safe')
Alternatives:
* Mitre saw better for straight cuts on strip
* Table saw better for straight rip cuts, where thickness allows
* Mini bandsaw and/ or scroll saw for tighter curves
===Parts of the Saw===
Point Out:
* The blade
* Inside the cabinet, the wheels
* The wheel tension adjustment
* The top and bottom guides
* The guide height adjuster
* The table
* The fence
* The fence rail adjustment
* The table bevel adjustment
* The on/off switch
===Types of Blade===
'Level 1' membership from this induction does not cover changing blades and setting guides, that's a 'level 2' task. Once you're familiar with running a bandsaw please talk to us about it, the more people we have who can do that the better
* LHS default is a 3/8" 6TPI, a good all-rounder. If you do swap out, always put this one back in
* We have a 1/4" which is great for tight curves on thick material (use mini bandsaw for tight curves on thinner stuff)
* We have some thicker ones for deep resawing, which require very careful setup
===How to Check the Blade Tension===
Open bottom cabinet, bend it between the guide and wheel. All members should try this by hand just to get a 'feel' for what they're looking for
===How to Check the Guides===
Basically,
* All rollers almost touching, but ideally not quite
* Teeth just sticking out of the side rollers, nothing pinched
Good source of info is this video: [https://www.youtube.com/watch?v=wGbZqWac0jU]
If it's not right, report to maintainers and we'll sort it
===Straight Freehand Cutting===
# Set guides to the correct height, just clearing
# Mark a line on the work
# Turn on not touching the work, allow to reach full speed
# Gently start cutting
# Push through. Be mindful of hand position, ideally never parallel or directly in front of the blade, push sticks available
# If stop-cutting, switch off before backing out
# Allow to fully stop before collecting workpiece
===Straight Cutting with the Fence===
Introduce the concept of drift. Fence will intentionally never be exactly 90° to the table (exact opposite of table saw)
Fence can be rotated to different positions depending on need
# Position fence as needed
# Procedure follows freehand cut
===Curve Cutting===
# Get fence as much out of the way as possible
# Follow procedure for freehand straight cut
# Listen carefully to know when it's not happy
===After Use===
# Always Sweep down the saw and the surrounding bench
# For now, always hoover inside the bottom box.
# Hoover inside the top box once a month or so. Once there is dust extraction the same will apply to the lower box.
