==Friends of ENTS==
+
== Equipment Settings ==
Many prospecting members love the ENTS concept and space, but simply don't have time to make full use of a membership. They still however want to keep up to date and be able to stop in from time to time and see what's going on. ENTS is happy to announce the Friends of ENTS membership.
+
Spindle speed: Be mindful of what spindle speed the gearbox is set to. Different diameters and materials require different spindle speeds. Consult your Machinist's Handbook, the internet, or the handy (but woefully incomplete) chart on the wall behind the lathe for appropriate spindle speeds. For example, brass and aluminum can be turned much faster than steel or cast iron.
Friends of ENTS pay a reduced membership in exchange for reduced access and features. Friends are not eligible for keys but may use the space during scheduled events. Voting rights and certain equipment is restricted to members.  
+
  
==What are membership costs?==
+
== Safety ==
'''Monthly''' memberships are $50<br />
+
1. NEVER leave the key in the chuck. Never. Not even for one second. Never never never. <br>
'''Starving Hacker''' memberships are available by request<br />
+
2. Do not pick up chips unless you are absolutely 100% certain they have cooled. Once they have cooled, let them cool some more. Even then, it is better to simply push them off with a brush or pick up the long stringy ones with a pair of pliers. Further, this should never be done with the machine running; long chips could snag on the part or chuck and start whipping around. <br>
'''Yearly''' memberships are available for $500<br />
+
3. Parts should never protrude from the chuck jaws more than 3 times the diameter of the part without being supported by a dead or live center in the tailstock, or a steady rest (that we do not have yet). Parts shorter than their diameter should ideally be at least halfway in the chuck. <br>
'''Friends of ENTS''' memberships are $10/month<br />
+
4. Disengage the feedscrew transmission when not using it, and of course the halfnut on the carriage. <br>
There is no requirement for ongoing membership, should you need to suspend your membership, let the directors know when to suspend and resume your membership.  
+
5. Long, thin parts that extend out the back of the headstock should be sheathed inside a very loose-fitting fixed tube to prevent them from whipping around and bending over, essentially becoming a weedwhacker on steroids. <br>
 +
6. Regularly check that the chuck is firmly affixed to the spindle nose. There is a short allen key in the lathe tool box that will fit between the spindle nose and gearbox. <br>
 +
7a. When polishing with abrasive paper/strips, never let it wrap more than halfway around the part. It can snag on itself and pull your fingers into the part. <br>
 +
7b. If polishing the inside diameter, never never never insert your finger in the hole. Wrap the abrasive around a small wood or plastic dowel that is significantly smaller than the ID of the hole. <br>
 +
8. Verify the spindle speed is appropriate for the diameter and material you are working on. <br>
 +
9. No long hair! NO LONG HAIR! Not even a ponytail is acceptable. If you have long hair, put it up under a hat or in a bun or something. Tying it back is NOT acceptable. We would rather see you looking silly than looking dead. If you don't believe me, do a google image search for "lathe accident" and you will see why. No loose long sleeve shirts, no dangling drawstrings on hooded sweaters, no loose jewelry/rings, no headphones, no neckties. If you are observed with any of these while operating this machinery, you will be asked to stop immediately. <br>
 +
10. Safety glasses are always a very good idea, however, if they fog up and obstruct your vision, stop what you are doing and get a different pair. It's still extremely dangerous not being able to see, even if your eyes are protected. <br>
 +
11. Do not wear gloves while working on the lathe. They can snag and pull you in.
  
==How to pay==
+
== Known Problems ==
ENTS prefers that members pay their dues via recurring PayPal subscriptions, as it helps greatly with budgeting<br />
+
The quill in the tailstock is not captive. If you crank the feed too much, it WILL disengage from the feedscrew, possibly screwing up your work. Be cautious of this. If you can see the keyway machined in the top of the quill, it's starting to extend too far. Stop your work, retract the quill, and reposition the tailstock closer to the work. This is a design flaw, not a failure of the equipment. We will (eventually) take steps to ensure the quill is captive, probably by machining a groove in the bottom of the quill and adding a set screw, as is standard on many lathes.
Members can however pay by single paypal payments, cash or cheque. <br />
+
ENTS does not offer an type of trading of labour, materials or tools for membership, sorry. <br />

The quill in the tailstock is not captive. If you crank the feed too much, it WILL disengage from the feedscrew, possibly screwing up your work. Be cautious of this. If you can see the keyway machined in the top of the quill, it's starting to extend too far. Stop your work, retract the quill, and reposition the tailstock closer to the work. This is a design flaw, not a failure of the equipment. We will (eventually) take steps to ensure the quill is captive, probably by machining a groove in the bottom of the quill and adding a set screw, as is standard on many lathes.

Future Ideas

Add a chip pan below the lathe to catch aluminum (and only aluminum, do not cross-contaminate!) for recovery and recycling in the foundry.
