J. Phil Thien's Projects

Thought this might be of some interest as it uses two different chambers to remove two sizes of dust (claimed). Certainly some interesting thinking went into it.

I'm concerned that all the swirling around I am seeing in the clear bag hanging down below the Wynn filter is evidence of scrubbing, and if I should do anything about it.

Completed a build which that turns on a DC whenever the machine(s) associated with it draws power, and senses when the DC barrel is full and kills power to the blower. The priorities for this project were reliability, low cost, and an easy build. Requires five components beyond common wiring materials and an enclosure for an all-in cost of ~$105 (lot of ebay). Build time was five hours (I'm kinda slow) not including rounding up the materials.

Uses a 2hp rated mercury filled relay for the blower, in which one conductor is wired to a metal cup of mercury and the other a probe that is dropped into the cup, eliminating noise, heat, and arcing. Extremely robust.

Thanks to this group for suggesting the Hawkeye current sensor and to a thread over at sawmill creek with the proximity sensor part numbers.

I was thinking about ways to remote switch DC's and Vacs. I know this has been kicked around before but I was looking for a very low cost yet crisp execution.
Build #1, at the milling machine I have a vac in a cabinet next to the mill with the hose run out of it, the nozzle is often attached near the cutter with magnets and sucks the chips up as they are made, also quite useful for clean up. Being in the cabinet it is very quiet, but the on-off switch ends up in the cabinet so I've just been plugging and unplugging it-super lame.

Solution took .5 hour to build:
A TORK TRP-D self ballasted relay ($25 for 4 of them on Ebay) was threaded into an outdoor style box (had it laying around), phone wire was run to the LED illuminated switch ($7 from Zoro tools). Cord from box to wall, outlet installed in box, done.  TORK relay is rated 1HP 120v to 277v.  The LV wire can be run to blast gates and gates used as a switch. Relay supplies 24V if needed, in this case powers the red led when on.



Other ideas:
A 2HP version for my DC (+$35).
A version that senses 'wind' from the TS blade, such that the DC runs when the blade is spinning (+$12).
A wireless version (+$50 for the receiver and $25 for each remote switch).

Still trying to figure out a way to combine wireless and wind sensor.

I'm open to ideas and feedback on the concepts,

keep it clean,

I tried without success to find a discussion on a setup where, in order to compress the height, the wynn is mounted facing down and there isn't a bag. This means the fines will end up in the filter housing but with the low air movement at that stage maybe everything just falls to the bottom. Perhaps there could be an opening in the bottom and a small container attached to catch the fines.
Hoping someone has tried this and can report,
Thank You,
