We the membership of Pumping Station: One add a CNC router and associated accessories 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 $22,750 to directly purchase a CNC router with associated accessories, and, if necessary, to run a power line supplying the correct voltage/current to the machine. This amount shall include the costs of shipping the purchase to Pumping Station One. This spending authority will expire when this purchase is made or at the time a new budget is passed, whichever occurs first. 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 one month of the purchase date.

History

  • 2014-02-25 - discussion open on member list
  • 2014-03-20 - open meeting held at PS1 to discuss the purchase
  • 2014-04-01 - Announced
  • 2014-04-08 - Vote passes

Background

The proposal is to buy a large format CNC router. The current CNC has work area and cutting power limitations that limit it to very small parts and slow speeds.

At an open meeting we discussed (3) possible options.

  • Build our own
  • Buy a used industrial machine
  • Buy a Shopbot

The consensus was buying a Shopbot was the most likely option to achieve our goal with minimal risk. A Shopbot is a turnkey solution with a 2 year warranty and has a smaller footprint than industrial machines with similar work areas. The included Shopbot CAM software is basically the same as the smaller machine so certifications will be easier.

Extra stuff:

  • Shipping
  • CNC Router
  • Dust collection - If a larger, shop wide dust collection system is desired the money would be transferred to that
  • Wiring - The power requirements (see below) are simpler that the bridgeport, but there will be expenses to do a proper and robust installation.

Receipts will be linked below.

Budget

  • $12,895 (#10108) PRSstandard
    • Normal Work Area: 96"x 48"x 6"
    • Movement Limits: 102" x 50" x 8"
    • Floor Foot Print: 120" x 79" x 67"
    • Recommended Clearance: 30" around all sides.
  • $2,619 (#12541) HSD 2.2HP 3 Phase Variable Frequency Spindle; 230v (single or 3-phase options) (includes 4 ER25 collets)
    • Quieter than standard spindle
    • Software controlled speed.
  • $600 Dust collector (may be part of larger area dust collection project)
  • $950 Shipping (ShopBot quote)
  • $900 Computer & Monitor
  • $400 Electrical
  • 10% Buffer for additional shipping and install costs.

Potential Locations

  • Along junk rack at the front of the welding area. This allows easy, non disruptive handling of large material.
  • In the wood shop. Matt Triano said (I believe) that he'll make room.

Electrical Requirements

  • 220VAC 20Amp (single or 3 phase optional)

Language

Authorize the board to spend $20,200 on a large format CNC router and related expenses. Authorization expires in 90 days.
