Which one do you prefer?
I like the right!

Those look … different.

Used a lot of Penofin - honestly I found it hard to apply to some of the figured / end-grain parts. In the wrong light it looks faded and kinda ashy. For the straight grain pieces (whatever the opposite of end grain is) it worked really well. However, it felt like an hour between the two thin coats was too long - maybe that’s because it was like 150 degrees outside.

Obsolete parts are better than obfuscated parts.

Added a second shelf in the back of the van. Now it's much easier to access the miter saw stand and saw horses, without having to remove tools bags off of them.
Top Shelf work for sure!

I'm looking for suppliers of 6922 tubes for the T2 in the EU.
Any suggestions?
Maybe after Serbia joins the EU? http://www.tubes.rs/ The gentlemen that runs that website might have a good lead for you though.

Not today, but yesterday: had an interview with a hiring manager, it's a really good fit both ways. They called me back THE SAME DAY to set up an (actually) in-person interview, which means they will probably move forward with an offer.
I am excite.
Congrats!

I would swear that I posted this the other day, but who knows anymore. It is called Transparent Ipe for hardwoods.
I thought that too.. but the can just says Transparent Natural, so who knows

I also have run those voltages through Switchcraft EN3 series which I like a lot.

Mine cut fairly smooth but looks similar. Looks completely different with finish. Just a pain in the ass to deal with so gave it all away.
Cool. Is that the natural/ clear tint Penofin?
-
This is my first time to use Ipe. It seems that depending on how it’s cut (which seems obvious now, but anyways) there are sections that end up with this sort of mottled grain. This is normal, right? This isn’t end-grain but it’s 90 degrees to the typical smooth lines you see.. I should have better planned for this feature of the wood..
Here is what I am referring to:
-
Where the wires go into the toroid is probably the place to tweak a bit. Rotate them both towards the shaft if possible. The only other issue might be getting the wires safely to the 4PDT switch.

Put some walnuts (Texas Walnut aka juglans microcarpa) into simulated winter … aka in my refrigerator.
i think it’s pretty cool that walnut trees give off a poison that prevents other plants from growing nearby and competing with it ☠️

Yes, but more importantly, is it audible? The software doesn't appear to smooth the data.
The avgRPM assignment does a bit of smoothing.
There are not a lot of mechanical losses, the belt has reasonable friction on the pulley and platter, so it can alter the platter speed with reasonable accuracy without it acting like a flywheel.
I don’t know how much is audible but I can say that +/- 0.03 rpm isn’t audible and it makes adjustments less than this.
Gor reference, the added friction of lowering the needle into the groove slows rotation about this amount.

Does that jump in speed every time the platter rotates? Or does it quickly reach a steady state and stop altering the speed?
Do you mean does the motor alter its speed at each rotation?

Hence the !digitalRead call. Clever.
Yup - I guess in this case the difference was black and white.

I would probably find it humorous as well if I could decipher what it is you're saying.
My little box works by counting the number of times it sees something pass as the platter spins. You need to check fast enough so you don’t miss the thing as it passes by. The faster you can check you can increase the accuracy of your measurement.
Originally I used a magnet and this worked well but seemed a bit less than ideal near a sensitive phono pickup. So I changed to using light.
In order to make the sensor work with other types of light present (such as the light that comes out of a light bulb) I used certain frequency of infrared light. This light is emitted by my box and then when that light is reflected back from the object it notes that the object has passed and it computes the speed.
With an acrylic platter with a record on top when the box asks if it has seen the reflected light, it says no until the white dot comes by, which reflects all frequencies of light and registers a “yes” with the system. But when an aluminum platter is used it always reflects the light. So I needed something that didn’t reflect the light I was using, which ends up being a black dot which absorbs light.
One made the “physical” change in how the device operated I made a simple change in the code that basically looked for when the reflected light wasn’t present - which was the exact opposite to how it used to work with the white dot.

So, a bit of a stretch for this thread and I am doubting anyone will see the humor in this. But as y’all know o have been working in a tachometer feedback loop for my platter. With the lid off it looks like this:
Previously I had an acrylic platter with a white dot that triggered the IR sensor each time it went around and used that to calculate the platter speed.
Now I have an aluminum platter. To make it all work I had to add a black dot and update the code as follows.
.. anyways I found this humorous.

So I have been trying out cables, and spending more than I normally would for some wonderful silver ones that seem to make a VERY noticeable improvement....as a result, Audiogon "recommends" for me the following....
I think one of these things is not like the other 😄
Send all the extras over here for proper disposal

So I received the bushing set a day early and think I got it all setup. I guess the dust collection has to come off when using the bushing insert?

So working to get my sacd player back in rotation. That means I need to stack two components on top of each other.
my rack has one open location, then two shelves behind a door. I have:
Pass XP15, Esoteric K-05x, MiniDSP SHD, Berning MicroZOTL (old style)
I was thinking of the digital spinner on the bottom, as it needs the rear cutouts for inflexible cables. I like the amp visible on top. That then means stacking the miniDSP on the photo stage or under the amp and not sure which one is better. It’s a tight fit either way.
As an aside I will run the spinner single ended as I need the extra balanced voltage swing for my low output carts. I haven’t done this yet so that will be a bit of a change. I guess I need to find a cable long enough - been a while since I bought a RCA cable
Any suggestions or thoughts?-

I refinished a stock. After removing the finish, used something called timberluxe - it’s birth year linseed oil and pixie dust I guess … it’s reassuringly expensive and doesn’t last long once air gets in the bottle. Then used a few coats of wax. Ta da!
My second project was quite the opposite in terms of success. The stock used a stain/filler base with crappy poly top coat - it’s almost like it had hand drawn dark grain streaks to simulate flamed walnut appearance. I am going to have to regroup and figure out how to re-attempt that one.
