We want to see a large manual mill capable of basic and advanced work brought into PS1 with the associated tooling to make it a useful tool for the space.

===Background===

=== Background ===

Currently Pumping Station: One owns no functional machining equipment. While the shop appears well served, all functioning equipment in the shop is on loan from the members. Given the extended interest and support of the members for the machining area it is high time that the space recognizes and supports the machine shop. Space ownership of the tool should also facilitate certification, as initial certification will not be bottlenecked at the owner. The membership has already pledged funds in excess of $3600 to facilitate purchase of a mill, which indicates the desire of the membership for this equipment.

===Parallel fundraising===

=== Parallel fundraising ===

This vote does not preclude further fundraising to reduce the impact a mill purchase would have on the finances of PS1. With the passage of this vote members could additionally be encouraged to donate directly to PS1, earmarking the funds for the mill purchase, rather than contributing to the pledges that will be used for tooling. This would allow parallel efforts to raise funds to offset the purchase cost. Since there is no official authorization to purchase a mill these efforts cannot reasonably start until after this vote.

===Ongoing expenses===

=== Ongoing expenses ===

While this vote would explicitly authorize a single payment, this type of tool incurs ongoing costs. In order for a milling machine to remain useful a stock of sharp end-mills must be kept on hand. While end mills do wear out with use, they are not single use items. Consequently these must be treated like the drill bits kept in the wood and metal shops, or saw blades for the Saw-Stop, and periodically replaced/sharpened. This will constitute an ongoing expense to the space. Specialty bits like ball end, or corner rounding bits should be purchased by the members using them. A small collection of stock should also be made available for certification and spur of the moment projects. These things will increase the operating costs of the metal area, but only in proportion with the usage of the machine.

===Why not a CNC mill?===

=== Why not a CNC mill? ===

CNC mills of the size we are considering here can be very dangerous, both to their operators and to themselves. Nothing stops a user from programming a CNC mill from cutting itself into chunks. Further CNC mills do not have the sensors to detect when they are cutting something they aren’t supposed to. This makes them additionally dangerous as operators are frequently tempted to reach into the work area to clear away chips or add cutting fluids. This can result in the machine cutting into whatever entered the working area unexpectedly. Further, many CNC conversions are made by removing some of the hand controls and replacing them with motors. This reduces their usefulness as manual mills. Additionally, most CNC mills come from production environments. This means that they are more likely to be used very hard before re-sale, and are more likely to have problems with slop and wear that are not evident on an initial inspection. Finally, in order to program a CNC mill safely, the operator needs an understanding of how mills operate. Since this understanding is most readily gained by using a manual mill, it makes sense for PS1 to purchase a manual mill first, and then expand with a CNC mill if that capability is desired.

We the membership of Pumping Station: One add a milling machine(1) to the list of discretionary capital expenditures in the Pumping Station One budget. If this vote passes the board of Pumping Station One will be authorized to expend up to but not exceeding $4000 to directly purchase a manual milling machine. This amount shall include the costs of shipping the purchased machine to Pumping Station One. This vote will make a milling machine the first item on the list of discretionary purchases as established in the current budget. This spending authority will expire upon purchase of a mill or at the time a new budget is passed, whichever occurs first.(2) Upon completion of this purchase a full account of the monies spent and equipment purchased will be presented by the Treasurer of Pumping Station One to the membership via the mailing list within 1 month of the purchase date. PS1 will not be responsible for purchasing additional tooling to make the mill functional. Interested members have already pledged more than $3600 towards the purchase of a quality milling machine. If this vote passes, these pledged funds will be used to purchase a set of tooling(3) that will ensure the mill is capable of most member projects.
