Silencing mill engines?

 I don't have a mill yet, But they seem pretty loud.  Why haven't they figured out a way to really muffle the sound?  To silence them to make them really quiet?
Anything someone can design, I can sure figure out how to fix!
If I say it\\\\\\\'s going to take so long, multiply that by at least 3!

If you wanted a mill that is not loud you could.  Get an electric
Mill the downside is your mill is stationary

Who makes electric?  I didnt think that was an option with Woodmizer.  I wouldnt had minded that as I have no intention of taking mine anywhere but where I put it.  I have room for it in my building but I am worried about exhaust fumes.

Yes WM does. I think Bibbyman and ElectricAl are using electric Woodmizers.

I called WoodMizer this morning and they said that the 10hp electric is only for the LT15, I have the LT10, dont really understand why it wouldnt work for the 10 but who am I to argue.

I often complain to Wood-Mizer that they treat their electric mills like red headed stepchildren.  They don't advertise them or expand the electric motor option to many of their mill models.   You can also get an electric motor on the LT40 Super, LT50 and LT70. I don't think a motor is optional on the LT28 or LT35.

It's possible to make a gas engine much quieter by fitting an aftermarket muffler. Wont be as quiet as an electric, but it should possible to get the engine noise down to comparable to the blade noise, and there is no point going much quieter than that.

Why don't they do it? Cost, and the engine isn't as compact any more (with a honking big car type muffler poking out the top. But on a mill you can mount a length of pipe and big can up top out of the way

But look at those little poirtable 4 stroke Honda generators for example? Much quieter than a standard Briggs $ Stratton, or even a normal Honda stationary engine.

If you have any kind of mechanical ability, just put one on anyway.

I put an electric motor on my Peterson WPF mill. It's interchangable with my planer.

The latest diesel engines used on Wood-Mizer are quieter than the older engines.

Besides being quieter, electric motors are dirt cheap to run and vertical maintenance free.  If you don't need mobile, electric is a winner in every category.

My mill came with a 13hp honda. I swapped it out with a 20hp honda v-twin. I had clearance issues with the exhaust so I just bought some black gas pipe and a couple screw on mufflers and fabbed up a new exhaust. It sounds just like a Harley! I always wear ear plugs.

There are Mufflers, and there are Exhaust Systems....

They may not always be the same thing...   :D

I put a 10 hp electric motor on my bandsaw when I built it so I would not have to hear it inside the building,all I hear is the blade.David

I have an LT40 with the 35.9 diesel. There is an optional remote controls see (command Control)
This feature allows you two great advantages
One: you are away from the noice of the engine
Two: You are away from the dust. This engine swiles the dust back to the the front of the LT40's radiator and if you do not have the option all that dust is in your face

I love it

Cherry bombs would be fairly quiet actually. Also extending the muffler up vertically with a flapper on top will direct a lot of the sound upwards away from you.

What pineywoods said, the lt10 head is not built as heavy as the lt15 head. And a 10hp electric is much heavier than a 10 hp gas. Which is why I sort of gave up putting a bigger engine on mine, it would take a bunch of beefing up to support the weight and torque.

Most engine manufacturers have optional quieter mufflers.When I had the two cylinder wisconsin engine on my bandmill I made  an add on muffler clamped to the origional mufflers output. Frank C.

So the kohler 7hp weighs 39lbs and the 14hp version weighs 73lbs. That 34lb difference  is almost 2 engines. I am doing the swap anyways, i dont like having to push the head down.

The 23hp Briggs Vangard is no louder than a garden tractor-- the chain saw is a much bigger issue.  The best muffler is inexpensive, moves easily from one machine to another, and protects your eyes, face, & head, as well.

Well I opted for the 10HP when I bought my mill I am hoping to set it up this weekend in my woodshop.  This raises a question, when I am running the machine indoors can I simply open the overhead door or is it better to find a way to exhaust it differently?  I would think that opening the overhead would be enough.

Let me know

I think the 10hp will do fine for hobby use. It just takes a little longer in the really wide cuts :) You should be ok with the door open, that's what I did when mine was in a barn.
