Editing Instructions:Large Finishing Tumbler (section)

== '''Operating the Machine''' ==
'''1. Ensure Tumbler is empty and clean'''

* The Tumbler must be cleaned out after every use, so make sure that the tumbling media has been removed.
* If there is media still in the tumbler, ensure you put it into the correctly labeled containers.  
* Wash and scrub the interior of the tank, using water from the hose by the double doors, or the waterjet. A light scrub to remove any possible contaminant is needed to prevent cross contamination between media. 
{{Discuss | 
* is a brush available for this purpose? Should the splash goggles be worn for this? 
}}

'''2. Prepare Lubricant/Pump''' 

* Ensure lubricant bucket is cleaned and scrubbed for use to remove any contamination between media. 
* Fill bucket with water (from waterjet hose or by the double doors) and one pump of the appropriate lubricant. 
* Put the bucket under the outflow hose beneath the tumbler, and put the pump into the bucket. Open the outflow valve at the top of the hose, and plug in the pump, ensuring good flow from each indicated hole in the water pipe at the top of the tumbler.

* the manual specifies pump precautions and the risk of pump burnout that are not reflected here as a hazard
}}

'''3. Load Media'''

* Load the correct media into the tumbler. Use all of the media supplied for the correct material. For example, if using the aluminum media, load the tumbler with all of the media. 
{{Discuss | 
* what is the weight of these buckets? Do we need safe practices for members to handle these safely? 
* manual mentions plugging outlet drain for dry media like corncob; how do we do that? 
}}

'''4. Prepare Parts for Tumbling'''

* Consider the loads you are putting into the machine. It can handle around 100lbs of parts, however a large amount of parts will reduce the efficiency and surface finish of the parts. Generally, smaller loads with less parts will tumble faster with a better surface finish, however larger loads will not harm the machine. 
* Flat parts can stick together face-to-face when tumbling due to the lubricant surface tension. It is highly recommended to put 1-2 zip ties on a part in order to prevent the parts from sticking to each other, which also helps with the motion of the tumbling in attaining a faster cutting and more consistent finish. You can run a zip tie through an existing hole in the part. If no holes are on the part you can run without a zip tie attached, however your surface finish may not be as uniform if there are many parts in the tumbler at once. 

'''5. Run Machine'''

* Run the machine, and slowly add parts to the machine.

* Run machine how?

* Tumbling results can be achieved from as low as 30 minutes, to multiple hours, depending on material, starting surface finish, and machine load. 

'''6. Clean Up/Machine Shutdown''' 

* Once you have achieved your ideal surface finish, put gloves on, and remove parts while the machine is running, ensuring that you are aware of what parts are in the machine to avoid injury. The bucket does not have any moving parts or punch points. Once all the parts have been removed turn off the pump, and tumbler. 
* Let water drain for several minutes. Use that time to rinse and clean your parts.

* Where and how do we appropriately do this? There is no utility sink. 
}}
* Move the media bucket to the media drain. Open the drain and run the machine to shake the media into the buckets.
* Put buckets away
{{Discuss | 
* Again, we may need to consider safe lifting and moving
}}
* Clean the inside to remove contamination.

How?
}}
* Take water bucket and pour outside. Rinse and clean bucket. 
{{Discuss |
* the bucket will have water, lubricant, abrasive and metal residue. Is it appropriate to dispose of this by pouring this in the lane? 
* pouring water into the lane in the winter will cause ice, probably not a hazard we want to create
}}
* Do any final cleaning and ensure everything is cleaned up.
