Thanks all.  I think if I bevel it, should be fine, would keep the knife edge from catching.  No idea why it chipped, maybe I caught an edge.  Wondering if using the 4000 fine stone, if sharpening away from edge is just as good.  That would solve any blade edge chipping it it.  The stone really puts a nice polish on edge, finishing with imperceptible pressure applied.

My SJ-200 has a small chip on sharpening surface at edge of stone.  Is there any material to be had to fill in the chip?  Blade catches the chip, and wondering if there is any material to fill it, that would just wear down along with stone.  Maybe another solution would be rounding the edges of the chipped portion?  It's about 4x3mm area and maybe 1.5mm deep.

Try this, not kidding.

Run the machine.  With the name plate facing you, slowly tip/tilt  the machine back on the rear feet.  This will stop the noise on mine, but while in this orientation if I apply pressure on the wheel the noise returns.  The noise on mine will cease when tipped about 10 degrees, but still have a strange dull harmonic. If I tip it back further, say 50 degrees runs quiet with no irritating low volume wamp wamp wamp.  I consider this no way a fix.  I note when adding slight resistance, the drive spindle moves for a stronger bight, but it skews when doing so, and noise returns.

[The dog must be a malinois]

North Dakota to Maryland right at the Swamp..   Did the dog fool you? No, the "be" on your YT vid did. The dog must be a malinois.

In plain sight!

You're definitely not alone.
My T-4 ... also brand new (from Lee Valley), makes exactly the same noise.

The noise "goes away" when I press a knife to the wheel, but always returns when I lift the knife away.

This is really unacceptable, so begins the process of returning it.

**EDIT** ... returning it for replacement that is - I think the machine is fine, I just can't stand the noise

I've tried a few more start ups in vein.  If anything, actually louder and applying light or moderate pressure to wheel is no help.  I don't believe in coincidences either, I bet there is a bad run of these.

[The annoying sound of your T4 is a typical resonance of some component.]

Several years ago I was analysing some motor issue. In my T7 machine there is a good quality Austrian motor produced by ATB Spielberg GmbH. I was assured that the motors are tested in Sweden before expedition. In your T4 machine there is probably a similar motor only with smaller power.

The annoying sound of your T4 is a typical resonance of some component. Please try to tighten the locking screws of the sleeves for the universal support bar. Eventually check if the capacitor is firmly attached to the motor.

Good luck.

The thought of something inside vibrating was in my mind as well.  The noise is apparent with everything removed, all thumb screws, trough, angle tool etc.  I checked security of capacitor and it is solid.  Ran w/o the plastic bottom plate too, thats not the problem either.

That's the problem, was shipped half way across the country You're not in Belgium are you? Halfway across the country is like the next town over in the US.

That's the problem, was shipped half way across the country.  The margins on these things for Tormek must be incredible, or we're paying a hell of a tariff.  Hoping Tormek will make good, I don't fault the retailer. 

Makes the noise w/o tray or angle tool attached, yep I looked for an answer.  Memory creeping back, I used bench lathes for 20+ years.  Now I recall why I instinctively tried to stop the noise like I did.  I'm guessing (could be wrong) a motor bearing is spun.  When you jab at it, it may set the bearing for a moment.  Trouble is it is not a fix. This thing is brand new, very disappointed.  I'm gonna guess it's a Chinese motor. Hell of a lot of money to be broken out of the box.

Another thing I tried while noise is present was holding by handle and orienting the machine slightly in various angles, no change which again leads me to thinking it's the motor.

The noise in the video doesn't hold a candle to hearing it live, loud.

If it is operator error I'm going to feel ignorant.  Listen when prodded to get quiet, a ticking noise.  Once I get it quiet any use starts the noise right back up.

So I get the machine setup and talk about noisy.  I spent couple hours trying to diagnose.  Took off the leather wheel, roughened the drive wheel just a bit appears good. Removed the stone shaft, looks good and put a bit more lithium at the bushings.  Problem appears to be when the stone is installed.  It makes a terrible racket, but if I jab at the stone with my palm a few times it will then run quiet.   The thing will though soon go back to the noise, I can palm the stone (not stopping it, just applying quick pressure a few times) and noise will stop.  If I'm lucky and noise does not return during use, it always reappears if I stop then restart. 

I removed stone and put on the spacer and stropped some things, the noise did not appear when doing this, so I think it's related to stone installed problem.

Any advice?

Consider that 90 (T-8) to 120 (T-4) RPM is a 33.3% increase, but we must consider the wheel diameters.  Actually the surface speed of the T-4 Wheel isn't much greater than the T-8 when you do the math , it's a 6.6% increase. The actual drop in RPM needed on the T-4 to replicate the cutting speed of a T-8 is only ~7 RPM.  My guess is that is not anything significant in difference.  Considering many use computer software for edge angles vs an eyeball, is one reason I bring surface speed of the stone up.  For the very pedantic sharpeners!  Considering the electric grid in USA, you'd probably get over a 7 RPM difference from home to home. 

I've read some question the T-4 RPM is too fast at 120.  Can, or has anyone plugged the machine in to a motor speed control unit?  It reads the motor draws less than 2 amps and there are a few 15, and 20 amp controls available.  I built my own years ago for a router table, worked well.

As a person that used a Baldor Bench Lathe 12 hrs a day for ~25 years,  the 30 minute per hour really puzzles me for a $400+ setup.  What I find strange on the T-4 (maybe the 8 is same?) is the Stone wheel shaft just uses plastic bearings.  Why no roller bearings?  At the 120 RPM , they'd last indefinitely most likely.  Would be a interesting modification, has anyone done it?
