Language
Allocate $700 from the organization funds for parts to complete a cyclonic separator dust collection system for the woodworking area.
Background
Woodworking dust mitigation has been a longstanding issue at the hackerspace. Various member-driven DIY solutions have been attempted and ended up being either incomplete or unimplemented. In our latest effort to solve this problem, we communicated with a dust collection system manufacturer in hopes for a product donation, however they ultimately declined to help at this time.
At this point in our development I see value in spending organization funds to invest in a reasonably priced and capable dust collection system. The system would be completed in a timely manner and integrated into the current plans for the woodworking area. I base my proposal on this design from Kreg forums because we already own some of the components to complete it[1], thus recycling what we already have and driving down cost. While the system shall be constructed to be mobile (moving from tool to tool), we have material to attempt a stationary installation for added value. The cost breakdown follows. Note: expenses are overestimated for engineering purposes and efforts to cut costs on the project shall be attempted[2].
| Part | Cost |
|---|---|
| Cyclone | $179.97 |
| Cyclone Brace | $41.53 |
| 5" to 4" Reducer | $15.39 |
| 6" to 4" Reducer | $16.27 |
| 1 hp dust collector | $149.99 |
| Total | $403.15 |
| Total + 20% wiggle room | 483.78 |
| Required material | Approximate cost | Amount needed? |
|---|---|---|
| Lumber, 2x4x8' | TBD | 8 |
| Plywood, 4'x4'x1/2" (to be ripped down to 3'x3') | TBD | 1 |
| Casters, min 60lb load qty 4 | $16.64 for an 8 pack on Amazon | 1 |
| Screws, Spax, 2.5" construction qty 1 box | $7.97 at the Home Depot | 1 |
| Total | TBD | |
| Total + 20% wiggle room | TBD |
[1] - Namely a Rubbermaid Brute trash can, trash can lid and possibly dust collector unit.
[2] - Expected cost savings include: purchasing inlet reducers locally from Home Depot - if compatible ($23 savings); replacing cyclone brace with scrap lumber ($50 savings); re-appropriating Harbor Freight dust collector currently used by metalworking members ($350 savings) OR buying same 1HP collector from Harbor Freight (up to $185 savings); using lumber/casters/hardware already available in the space (up to $80 savings).
