Overview

Summary

The red dust collector we have is a Tempest CX and was donated by Dave Leer some time around summer/fall of 2013.

Purchased from Penn State Indiana

You can find the manual here: Manual.

Specs:

  • 2 HP motor
  • 12" steel impeller
  • Can run on 220VAC or 120VAC. We have ours wired to run at 220VAC.
  • 6 Inch input and output port. The main chip chute that goes to the waste barrel is 7 inches though! (Why??)

TODO

  • Make it easier to raise and lower the unit
    • Maybe put a pulley and chain above the unit and make the bottom of the stand a hinge.

Adding new drops and blast gates

We use these blast gates as they are very sturdy, clean themselves, and are easy to mount to things and mount things to them: http://www.leevalley.com/US/Wood/page.aspx?p=51506&cat=1,42401,62597 Get the keyed hose clamps to make your life significantly better.

The primary ductwork is 6" duct. We have mostly purchased the duct from Corken Steel over in Newport. Decent prices and they have a huge variety of parts (although you may need to wait a few days to get some parts). For flexible ducting the smaller stuff has been purchased from amazon/whereever. Larger 6" stuff should also be ordered from Lee Valley. http://www.leevalley.com/US/Wood/page.aspx?p=51505&cat=1,42401,62597,62604&ap=1

Controls

Greg way over-engineered a control system for it. There is a control panel for manual activation, and a (really shitty) web interface, dustor.at.hive13.org. Code is on GitHub.

If the off light is blinking red, the controls have been locked out. In a locked out state, the dust collector cannot be turned on at all. Lockout may be activated by holding down off for five seconds. It may be removed by holding on for five seconds. If the off light is steady red, it is off and waiting to be commanded on either by a button press or remotely.

If the on light is blinking green, the dust collector has been turned on by remote equipment - it'll shut back down when all the remote equipment has requested it off. Holding down the off switch for two seconds cancels all remote requests and shuts it down. If the on light is steady green, it has been turned on by the panel. Press the off switch to turn it off. If the on light begins blinking, it's been commanded on remotely.

TODO

  • Put another on/off switch over by the other hose.
  • Make the web interface, like, actually usable.
  • Put heatsink goo on the SSRs.
  • Have other devices be able to auto-maniacally [sic] start and stop the dust collector
    • Build some sort of device to tools getting power so they'll light the dust collector.
    • Mach3 supposedly has this capability built in.
    • Implement the automated blast gates described below.

Automated Blast Gate

The fuutttuurrreee is here! Let's turn our dust collector in to an IoT monster!

Requirements

  • The blast gates should still be usable if the automation doesn't work
  • Under ~$75/gate encompassing all of the gates and electronics so we don't blow a ridiculous amount of money on this.
  • Be able to easily add new tools and blast gates
  • Nice to have: when tools get turned on they auto open the blast

Two options will be listed here to be decided on later

Pneumatic

Most people online who have made their own automated blast gates have gone the pneumatic route. This is likely because very few woodworkers have electronics knowledge.

Pneumatic cylinders with the correct throw lengths can be had relatively cheaply from ebay. Solenoids to actuate them are not insanely expensive, but sometimes require weird methods to drive them.

Downsides are that this requires compressed air to be run to the main controller and then to each blast gate. This means that the air compressor must be pressurized as well. :(

This would be very easy to mount to the blast gates.

Rack and pinion

This would use a stepper to drive a rack and pinion on the blast gate. This is how the kind you generally buy in store are done. It will still allow easy opening and closing even when on or off.

Would make it easy to have blast gates open/dust collector turn on when a tool is turned on.

We have quite a handful of

Work Log

Unknown date

Stand built and unit mounted.

220VAC drop has been run to the dust collector.

Made the power cord longer for the unit.

26 September 2014

Purchased six 5ft sections of 6" ducting, five wyes (45 degree split), and a handful of other items to start running the duct work!

10 October 2014

Dave and Jon installed most of the purchased ducting. Planned out the extra pieces needed to finish out the rigid duct work.

29 December 2014

More ductwork purchased to start hooking up smaller tools along the back workbench.

Late March 2015

The CNC Router is almost done and is making lots of dust. It has been hooked up to the dust collector. The filter + dust bin should be hooked up to the dust collector shortly so the CNC can be used properly!

April 2015

Filter and dust bin have been permanently attached to the dust collector. It is now effectively operational. The final pieces of rigid ducting needs to be added and the rest of the tools need to be connected.

November 2015

An extra outlet was added. Jon attempted to add a solid state relay to start having tools automatically turn the dust collector on. SSR broke, needs a new one.

The bandsaw was fitted with dust collection ports and connected to the system.

August 2016

Greg got two new SSRs for the dust collector (since the collector uses 220v which is two hots). They are heatsinked so the shouldn't die nearly as fast as the last one!

January - February 2017

Added ports for the following tools:

  • Router
  • Spindler Sander
  • Radial Arm Saw

Added vacuum attachments near central column, and in the back corner for the drill press/lathe.

Table Saw now connects via temporary connection into the dust collection port on the side.

Improved the overall ducting, including adding screws

Added new vent to blow the fine dust out the window

Added new dust collection box with see-through front to make it easy to detect when dust collection is full.

March-April 2017

Improved controls
