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 $180
Cyclone Brace $50
5" to 4" Reducer $20
6" to 4" Reducer $20
1.5HP Dust Collector $350
Lumber, casters, other hardware $80
Total $700

[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).

Costs

Here is a breakdown of what this project should actually cost. I'm adding 20% wiggle room to the totals for taxes and any unforeseen costs.

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' $3.12 ea (menards) 8
Plywood, 4'x4'x1/2" (to be ripped down to 3'x3') $12.06 ea (menards) 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 $61.63
Total + 20% wiggle room $73.96
    • Grand total with extra 20%: $557.74**

And there's still the option to save money by reusing things we already have or buying cheaper parts at Home Depot.
