{{: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. | |||
