Just like Phil,
I was wondering why not covering the entire cabinet with insulation or the whole outer tub?! I imagine that small patches are enough to dampen the vibration in the cabinet?

FD 1-18 With Quite-PAC

Good Job Jon, I wounder if it will be as quite as mine, the race is on.

SPL meter

If you have a smart phone like an iPhone (or even a slightly less smart Android) there is an App for that!!

There are both free and cheap apps, be sure read the reviews. I bought the Studio Six Audio Tools package that does lots of other cool sound stuff too.

Head to the App Store and let the competition ensue. There should be a standard distance established for meter placement.

Nice job with the sound insulation Jon! I knew these are not the quietest machines on the planet since they let you know that a heavy duty beast is at work in your laundry, pulsing away.

Jetcone Improvement # J1

In taking a long look at the noise generation capabilities of these machines I spotted a few more areas that needed my attention. Places John LeFever missed in his machine.

 

The springs are a source of great noise along with low water level washing in the 1-18's.  If you will notice, the springs attach to the base plate with metal to metal hooks. This is no different than a sounding board on a GRAND PIANO !

Also the tub will act like a big timpan drum and the cabinet will help to resonate all this sound.

In thinking on it I first tried using rubber hose hooked around the ends of the springs. Too cumbersome and  it wouldn't stay put. Then it hit me electrical tape, nice and gooey, might stay in place and deaden the spring resonances. 

So I taped all the hook ends of the springs. See the vidotic proof today ! Here and now !

To answer the question of not completely covering the cabinet panels or the baseplate- all you need to do is dampen the resonances in the sheet metal to silence the noise. You don't need to create a complete shield to damp out the incredibly loud pounding of a 1 -18.

A running test

Note: How quiet the machine is now in slow/ fast agitation and in slow/fast spin. No more rattling of the out of tune springs. Their oscillations are no longer transferred to the tub ( drum) and baseplate ( sounding board).

The tapping in spin was caused by my magnetic trouble lamp on the back of the tub. At the end I remove the noise so you can hear the true sound without the tapping.

The tub also spins quieter due to that black teflon water seal I installed, no more tub spin ringing from the original copper seal.

Also note with the new Spin Roller installed Poppy is braking on her own again ! First time I've ever got a rebuilt 1-18 to brake again !

Race begins indeed - I'm so impressed with those springs! Did you just wrap the entire hood end of the spring?

My Holy Grail 1-18 needs a spa treatment and some sound dampening as well, this is a great thread!!

"Show me what you look like when you're telling the

""Show me what you look like when you're telling the truth" from the radio at the end, kind of correlated to the job of silencing it. Truthfully, you see what it looks(sounds) like. Other conversations heard, before removing the mag.trouble lamp reveal the quiet-a-pakII doing the job.

You're a master at the craft…enjoying the show.

 

[philr]

I'm quite impressed Jon!

 

[travis]

Jon,

That's really great to see you make an already great example of this machine, top notch. You truly are a master.

 

[jetcone]

Thanks Phil, Phil, & Travis

This is one of my favorite models so its fun to revisit them, I made good $$ off these in the 1980's !!

 

Greg, I wrapped the entire hook end and down the spring leg a bit too, to help damp the spring too. 

 

I forgot to mention in the running video all you hear from the mechanism now is the chuff chuff of the bellows breathing in and out. Like a steam engine.

 

 

 

 

[kb0nes]

Jon, one other spring dampening trick to consider trying someday is a piece of resilient rubber hose. Something like stretchy latex or silicone tubing. Find a suitable size that fits snugly and slip it over the coils of the spring. Its a great way to damp any ringing!

Great thread to follow along, carry on!

Spring Coating

What about dipping the ends of the springs in that colored liquid rubber used to recoat tools?

14.5 oz. Plasti Dip® - Black | U.S. Plastic Corp.

Plasti Dip® is an air-dry, specialty rubber coating. In fact, it's the original peelable, flexible, insulating, non-slip, durable rubber ...

Oh...

and this is a GREAT THREAD!

Jon, you are a MADMAN and a GENIUS!

Malcolm

 

[jetcone]

Yeah Phil

I did think about that but thought it would interfere with the spring constant too much. It probably isn't crucial in this machine. Maybe I'll try that on my 3 Speed.

Wait you don't me on the coiled metal wire do you? You mean over the whole coil?

 

[mrb627]

Hooker?

Just the hook ends where they hang on the tub. (I think)

I was thinking along the same lines as Phil, some sort of wrap will quiet those springs down.....

on one Neptune dryer, the idler spring would 'sing' from the vibration when running, I used the foam you wrap pipes with for insulation....just a two inch piece centered over the spring quieted it right down.....amazing the noise that thing would generate, took a while to figure out where the noise was coming from...

noticed later that a few machines had a plastic mesh sleeve slid over the spring.....guess Maytag figured that one out too....

interesting things we come up with.....

love your work Jon.......

can't we have something like a weekend workshop and bring our 1-18's in for classroom rebuilds?....maybe at JohnL's in DC?

1-18 Noise Reduction

A good way of damping spring noise is to stuff really heavy foam rubber inside the coils of the springs.

Jon Be sure to bring your sound meter when you visit later this month, you might be surprised how quite my 1-18 is.

 

[turquoisedude]

It's wonderful!  You've done an amazing job, again, Jon!   You simply must come to Ogden and bring that brain transfer hat - we need to make the Dominion and the Hotpoint spin again... 

 

I think I may have to try some of that quiet-pack on the 56 GE dish-smasher... LOL  

 

 

 

[kb0nes]

Jon, yes just slip a snugs resilient sleeve of rubber tube over the coils to damp it. It won't alter the rate to any significant degree.

I have seen this done on various audio devices like mechanical reverb plates where resonances are a problem.
