Hurricane Sandy moving slowly...
460 miles SSE of Charleston SC, moving N at 6mph
Max sustained winds 80mph, 970mb
Hurricane force winds extend 35 miles, tropical storm force winds
extend 275 miles from the storm center.

Right you are... the latest Euro Model has the hurricane staying closer to the East Coast, then ramming up the Chesapeake Bay late on Monday evening. Current NHC track is a bit further east, thus hitting Delaware/NJ border. So far, Euro is looking better. link to that model

All DelMarVa interests should be in full prep mode right now.... including those that could be susceptible to inland flooding forced by storm surge near the top of the Bay.

Governors of Virginia and Maryland have declared states of emergency in advance of the storm.

***SURF'S UP!***

¿surf or serf?

There's always a first time for everything, but according to this map there's not been a 'cane follow the track currently forecast in October in the past 150yrs.

dammit - hurricanes just suck - feeder band just came thru - put me and mt boat over about 10 degree heel :~(

You ain’t kidding about the leaves. Our building that we used to be in South of York still has our servers in it. It is abandon so the drains of the roof are most likely clogged. Just waiting for all hell to break loose, water has to go somewhere.

Here's a graphic I made up that illustrates my concerns... (and I apologize for the size of this). The models are projecting the storm to arrive with a fairly steep "entry angle" - maybe driving due NW into the coast. That would forces many of the tributaries backward... causing major flooding.

This graphic is based on the latest European model run since it has been "most right' so far. If that turns out to be correct, then all waterways between Washington and Richmond will be impacted, though the area near King George, VA and SE from there could be the hardest hit.

But use this graphic as a guide -- as I say, the exact track is still unknown, plus it's going to be a large storm: Delaware Bay could very well get this instead with only a modest change in either the approach angle OR the timing of the NW turn... a difference in a couple of hours would change the landfall by 150 miles.

You can get premixed 2-cycle gas & oil in quart cans now most anyplace they sell lawn equipment.

I honestly hadn't seen that. I have three different mixes that drive me crazy. I will definitely look for it.

I'm covered on safety gear and log turners. Thanks

Hope everyone in the path is busy getting prepped today! Looks like a doozy of a storm.

[alancarp]

The models have shifted again... this time further north. The Euro is back to a hit from the Central NJ coast-to-NYC. The GFS is now all the way out to Cape Cod.

I'm not gonna redo the graphic from post 68... it's too big, and I don't wanna be "chasing" the models all weekend. Suffice it for now to say that almost all coastal areas will be impacted, and areas within 50-60 miles north of any landfall point will suffer some nasty inland flooding. That pic still illustrates the reasons way... regardless of who exactly ends up getting hit.

And really... if Sandy approaches via a more northerly trek, there would be a real danger of beach damage over a vast swath as it parallels the coast.

You will be shocked at the cost of the pre-mixed products. I can’t imagine why anyone would buy them. You can get “ratio-rite” products that make mixing easy.

Two strokes will run on an amazing range of mixing ratios and even non-specific petroleum or vegetable-based lubricants. In the old days it wasn’t that unusual to mix ordinary motor oil if a two-stroke lubricant wasn’t available, although you would never think of doing that now.

Each motor has an optimal ratio but even these can be debated. I personally have had motors whose specifications ranged from 20:1 to 100:1. The specs are developed based on operating temperature, jetting, performance requirements, load characteristics and metallurgy (bearing types, mostly). Correct jetting is often much more important than correct mixing ratio. The mixing ratio does affect the jetting, but the change is rather small within reason.

In a pinch, most of these motors can be run on ratios much more lean than specified. In fact, crankcases generally have quite a bit of oil sludge that provides adequate lubrication at low rpm, even with no premix at all!

Just buy a gallon of marine 2T oil and mix it at 50:1 and everything will be fine for the vast majority of motors. Even my air-cooled motors seem to tolerate that OK. I have generally stopped using tailored ratios except when spark plug appearance or spooge acccumulation suggests otherwise.

Interesting post, thanks.

I've several Stihl tools, including the go-to chainsaw, all of which specify 50:1.

Also have an inherited Jonesred chainsaw and trimmer, both of which are crap, and they specify 40:1.

For all the times I've had to F with that J saw, am gonna try pouring some 50:1 down its throat and free up a gas can !

maniacal LOL

Thanks. Everything but the tiller and 16" chainsaw are 50:1. Good to know. I was getting tired of mixing three different gallon containers.

LOL. Beat me to the post.

Older motors, like my 70’s dirt bikes, were designed for the lubricants of the time. Hence, the 20:1 recommendation. Even the cheapest Walmart premix now is far superior to what was available then.

But, by all means, if you know in advance that a heavy load scenario is likely, especially with high operating temperatures —say like a dirt bike tractoring through deep sand on a hot day — go by the manufacturer’s recommendations or reasonably close to it (i.e. don’t use 80:1 if the owner’s manual calls for 40:1).

I don’t have a gas chain saw but being air-cooled and used in high-stress conditions I imagine the use can fit into the “severe” category quite easily.

We are headed to our shore place tomorrow to bring everything in and then we are coming right back home and do the same thing on Sunday here.Our Realtor called and said volunteer’s are going to the houses were the owners can not get down.That's nice.We are under mandatory evacuation down there.

[tomkat]

Well, if my math is correct, the difference between a 40:1 & a 50:1 mix for one gallon = .64 oz.

So, apportioned into 128 ozs of fuel, the difference per oz. of gas is .005 oz of oil ?

Yep, worth a try . . worst case, the J will die and can be tossed with a clear(ish) conscience !

lol
