== Algemeen ==

The bobbin sander is suitable for most types of woods as wel as other material such as (hard, thermo-harding) plastic glass -- provided that it does not `gum up' the bobbin. As it is to be primarily used for wood - contamination or use with metal is out. (If you do need it for metal; take it to the metal shop and clean the machine extensively afterwards to avoid ruining the next woodmakers work).

== Opstelling ==

Make sure that the area around you is clear; and that nothing (including your clothing, hairs or jewelery) an be caught in the rotating parts. Be sure to connect the dust-exaction and either switch it on all the time (manual) or put it on `auto'. 

== Main rules and instructions ==

''Opmerking vooraf:'' Het veilig gebruiken van een zaagtafel leer je niet door het lezen van de wiki en de handleidingen; maar door goede praktijkinstructie en oefening op de machine. Vraag dus om hulp en instructie wanneer nodig.

# Use hearing protection, (safety)glasses and safe clothing.
# Leave the machine clean. If it is found not clean; clean it first; or do not use it. The last person to use it is responsible for leaving it fully and completely cleaned.
# Don't leave it running unattended.
# It is mandatory to report issues, malfunctions, lack of supplies to the mailing list.

Prior to use

# Verify that the machine is clean and looks ok.
# Make sure it is wired up; and connected to the dust extraction.
# Make sure the space around it is free/clean.
# Switch the machine shortly on - to check it runs smoothly; without vibration and that the dust extraction comes on.
# Check that the sand-paper is not slipping.
# Check your material for things like old nails.
# Keep listening to the sound of the machine; it should be regular without whining or high pitches.


In case of doubt - check the manual or ASK.

Wat betreft de machine schoon en veilig achterlaten - per algemene makerspace regel is dit altijd de verantwoordelijkheid van de *laatste* gebruiker. Dus als je de troep van een ander niet wil opruimen; meld het dan - en gebruik de machine niet. Zodra je iets gebruikt ben je verantwoordelijk voor het in goede en schone staat achterlaten van de machine; en het melden van storingen of defecten.

== Dangers ==

# Hair, loose clothing or similar getting caught and sucked in.
# Bits of machinery coming loose and flying around
# Dust and splinters in hands & eyes.
# Very high temperatures due to rubbing (rather than sanding) and smoldering wood.

== Instruction ==

Instruction is optional - do check the video - or ask on the mailing list if you want someone to show you. This generally takes 10-15 minutes.

Issues and defects to be reported to: deelnemers@makerspaceleiden.nl within 24 hours.

Accidents (i.e. that require first aid or fire extinguishers)  are to be reported at bestuur@makerspaceleiden.nl immediately.

= Use =

See the manual at: XX for full instructions; or the short primer below.

There are two ways to use the machine; with a round bobbin or with a short sanding belt. The first is useful for narrow corners; the latter for edges.

== Using the bobbin ==

[[Bestand:Osc-bobbin-mount.jpg|miniatuur|rechts|Mounting the bobbin 1]]

# Put the yellow plate (1) in the machine; 
# select a spacer (2) that is a bit larger than the bobbin (3) you are to use. And slide this over the pin.
# then slide the bobbin (3) over the pin.
# pick the largest washer (4) that still fits.
# Then use the knob to tighten it all; the rubber should expand a little to 'grab' the sanding paper.

[[Bestand:WP 20181021 15 17 57 Pro.jpg|miniatuur|left|make sure there is enough space]] 

When selecting the spacer (2) - be sure that there is space around the bobbin; as it will start moving up&down.

== Tasks ==

# Find/make Adaptor for dust extract.
# Upload pictures (currently on Yorims phone)
# Discuss if we need to fix this to the bench.
# Print safety sheet
