J. Phil Thien's Projects

Sorry for the delay.

It is THEEN.

I got a "page not found" on that link?

That one also says patent pending.

Huh.

@Phil

Sorry I have been out so long. Life happened ya know...

I am so sorry to hear that some jacknut is stealing your generously shared idea.

I'm no lawyer or anything like that, nor did I spend the night in a Holiday In Express, but if there is anything I can do to help with this issue. please let me know.

Wow, nice to hear from you.

Nothing much to do I guess.  I don't know what this guys application status is, I do know several reached-out to the patent office to object.

Hope you're doing well.

I'm here but nothing to report, I have no idea what the status of his patent may be.

I had never heard of a Younker lift, that is a pretty neat!

Very clever implementation!

Good stuff.

Running those large roundover bits in my table is a little on the exciting side, but I've done it.

Some have absolutely modified and tried to optimize the shape, I don't know whether the NACA shape specifically was used.

That, sir, is absolutely gorgeous!

What beautiful wood and grain.

What did you use for a finish?

Sorry it took me so long to notice this.

The purpose of that dowel is to provide a means of attaching the indicator.  You could just as easily screw (with a wood screw) the indicator into the block.

In my case I used the 1/4-20 threaded cross-dowel so I could turn it back and forth 90-degrees and use the same 1/4-20 screw to attach the indicator to both edges of that block.

I now realize that sometimes those videos guys make, would make this a whole lot easier to understand.  Unfortunately, I don't have a video.

Glad it worked for you!  I still use it routinely.

So whatcha making?

Sorry for the slow response.

1/4" because you're cutting the full depth of the material, because you're going to lose your pivot point when you're done.  1/2" is more difficult to plow through material.

Thank you but you're going to get an automatic response indicating they don't do anything with E-Mail.

I've snail-mailed them evidence of prior art.

The work is all in the public domain, I didn't receive a patent and certainly others have contributed improvements.

I'm honestly suspicious and question the motivations of anyone attempting to patent the work at this point.

Phil,

I will send an email to the patent office, but it won't be immediately, my wife has some unresolved medical problems. 

I don't know what improvements this guy has made to his design because he intentionally doesn't reveal those details.  However, for a brief moment when he lifts his unit off the bucket it is clear that at the heart of his device is the Thien baffle, copied shamelessly.  Without that baffle his device doesn't do squat!

I never contacted the guy, having the opinion at the time that his work was based entirely on the work of others (myself and others here).

The circular cross-section aspect he was claiming, should make the unit perform less-well on fines, as it would induce a 2nd rotation of everything above the baffle and allow the fines to approach the outlet tube during each of those rotations.  We want to keep fines AWAY from the outlet tube.

Good luck on your wife's medical problems, I'll keep you guys in my thoughts.
