J. Phil Thien's Projects

Very carefully. 8)

Back in June I showed off my Thien lid in a series of photos. Today, after shaking the heck out of the filter bag and going to lunch, I finally took a photo and carefully (albeit unscientifically) measured the result. The pic shows a plastic jar into which I dumped the contents of the original DC bag and the metal can content - - about 23+ times that of the jar, or about 96%.  True, I did not consider many factors such as compression, weight, or particulate size.  The only measure of concern to me is emptying frequency.

Anybody care to share and compare?

A+, Phil.  Thanks again!

Thought I' be duck tapin' my Behlens (Made in USA) 20 g can, but have not sensed any obvious leakage.  It's precision guesswork followed by trial and error.  Just lucky?  I kept reducing the size of the rabbit bearing to incrementally increase the rabbit and decrease the small diamater on the lid until it fit snugly.  Very happy with the result.

I spent two years on and off puzzling how to make it work and less than a day doing it.  Jump in.  This thing works!

Last week, I built my own Thien cyclone separator on a 20 gallon trash can, which fits the Delta 50-760 space better without  crowding.

I used the Rockler 34367 4" Dust Separator Components because they make a quick seal without glue or silicon and allow for later elbow angle tweaks.  Lid clearance between adjacent individual components on the top lid was borderline minimal, but I kept the output port exactly in the center and the input port still fit.  A 3/4" lid allows only a few threads to catch when assembling the component halves, so I routed a 1/4" deep counter bore recess around the bottom of each top lid hole. 

Despite careful measurements, when I test fitted the completed assembly, I realized that the can is not perfectly symmetrical. Depending on the rotation of the assembly, sometimes the top lid would spontaneously pop out. The large diameter arc on the basement level was rubbing on the can, so I had to shave 1/8".  Now everything fits well and does this thing ever suck!  At least 90% retention in the can!

Thanks Phil and collaborating contributors!

I bought a Delta tin 5" to 4" reducer a couple years ago before I got distracted.  It was smaller than the original Delta 50-760's stock  5" to 4" Y reducer, but still did not allow much room for a 30g metal can, so I trimmed it a bit with tin snips and still had to replace the 30 g can with a 20 g can.  Now, plenty of room. 

I searched online for the same Delta reducer I currently have, but all I found is an apparently taller plastic version:

With respect to an internal baffle within the 50-760 DC, I'm still wondering about design and efficacy - at a loss.  Anybody have pictures or a description?  I'm misssing something.
Thx.

Please clarify.  Except for input fittings and filters, has anybody made worthwhile internal modifications to a Delta 50-760 DC?

I'm about to make start this separator project, but I'm a little confused over what I've read and/or imagined.  Some of the words have led me to believe that others have actually modified the 50-760 inards.  All I've done is replace the input "Y" with a more compact 5" to 4" reducer.

Many thanks in advance!
