Coating+phase plugs to FE167

[planet10]

That looks pretty good... here are the whizzers of most recent 167s i did...

nd the phase plugs need doing too...

Are the patterns for decoration, or do they have an effect on breakup modes or something like that?

My phase plugs look a bit "dry". I first thought about oiling them... but with paint hat could be an issue. What do you advise?

Nice whizzer paintjob. I choose colourless as I am afraid the pattern will get distracting after a while (for me).

Here is a good start to read about it.

They work just like all the rest of the EnABL spots

They are finished with a polyeurathane clear finish. I use a #56 or #66 nib to put the dots. Just touch the tip.. watch you don't make to big a dot when you have a fresh load of pollyscale (on the plugs pretty easy to clean up with 1st a dry q-tip and then a wetted one if necessary). When you are running out of paint on the nib it might take a bit more work.

I will post the where and a picture with the template -- i've 2 more coats of clear and then i have to do 6 more plugs.

Did the inside of whizzer... ok, there seems to be a pattern.

Again, to make it visible I had to play a bit with he colours.

 

[JeroenR]

On the cone, under the whizzer. In the end it was less hard than I thought.

Now the coats and the phase plug to go...

This is much more work than I expected. Dave, your prices for enabl-ed drivers seem charity.

 

[JeroenR]

Almost finished.

The cones now got 3 coats of gloss, the whizzer one coat. It indeed looks glossy and feels very smooth. I was a bit afraid how the gloss would look but it turned out ok.

 

[JeroenR]

Ad here is the plug.

Dave, two last questions :

- can I coat the plug with the gloss I used for the cones? Only one coat?

- (of topic) Can I use the same recipe with my FE103Sigma's? Any experience with those?

Thanks!!

(I like this picture...)

I envy you guys that have the patience for this kind of work. I would be yanking my hair out! LOL

Today I mentioned to my GF that for both the drivers I had to paint 2,548 stripes/dots and added quickly : "please don't mention this to anyone.."

 

[planet10]

Those plugs look very well done.

Yes. Yes. (and a bit of PVA on the tip* and then gloss just on top of that). Yes

*(a tip -- get a cardboard box, cur a small pair of holes just big enuff to securely hold the plugs nose down. Add the PVA, and put the plugs nose down in the hole to set up.

2,548 stripes/dots

((144+144+144+216)/driver + (144+144+144+7)/plug)x2 = 2172

What did i miss?

Thanks!! Yep, good tip, my PVA was starting to hang down the tip, so applied two layers...

I'm listening to those FE103Sigma' for over 10 years now, I'm very curious if I notice the difference after EnABLE.

((144+144+144+216)/driver + (144+144+144+7)/plug)x2 = 2172

What did i miss?

Nothing. And I was wrong, but the number increases as I did a few dots three times...

(dots=stripes)

driver:
3 rings of 72 dots
1 ring of 108 dots
all touched/painted three time for some height
(3*72+108)*3=972

plug:
3 rings of 72 dots
1 ring of 12 dots (at top)
1 dot (top)
all touched/painted twice for a bit height
(3*72+12+1)*2=458

so two drivers is (972+458)*2=2860

That should be (i should never try to do stuff like that before the coffee takes affect )

((72+72+72+108)/driver + (72+72+72+13)/plug)x2 =36*15+26 = 566

I think these look awesome with the "clear" EnABL!

Dave, if I asked pretty please could I order a set done in clear instead of black or brown?

You'd be a guinea pig... not nearly as much visual feedback, wouldn't likely be quite as neat.

try to use plumbing copper tubes or caps for phase plugs. they'll lower impedance rise and increase drivers' power handling.
