Woe :(...Damage to MS200T

[Burnham]

Last week I pulled the 200T out of the saw box on my truck and was really bummed to find that the jostling around, which normally just does a bit of scuffing, had produced some real damage. Looks like the 200T got up against a dog tip on the 066 and the case took a chewing.

The damage is up front near the bottom. It's in the area of the bar oil tank, but I'm not sure if it actually is on the tank wall itself or just close...there's 3/4 tank of oil, so I cannot really see in to judge the inside profile of the tank.

The deepest part of the gouging is about 2mm deep, maybe 3mm. It does not breach the case, but I cannot imagine that there is much depth left there.

Can I patch this with epoxy or something like JB Weld? That was a thought I had and Pete McTree seconded when we talked about this recently. Should I?

Here's some pictures...I turned the saw over on it's side for the last 2 to show the damage more clearly.

Advice, please.

I'd JB weld that in a second.

Yes, that is the tank. Looks like you caught it in time but I agree that there can't be much wall thickness left there. I think your J B Weld idea is an excellent one.

I once had the cases on three saws seriously pitted by electrolysis. Darn near as bad as that, B. It happened through a combination of sea water, fish slime, the mag cases of the saws and a STEEL bottomed tool box. It was the makings of a battery. Leave set over the weekend like that, do not stir, and presto! It blew my mind how fast it happened. Another day or two the cases would of been totaled. Caught it just in time.

Now exactly how that fish slime got into the tool box is another story.

Fish slime....and i thought a saw claimed after sitting in the dump was a bad memory.

 

[Burnham]

Probably a good story, too .

Did you do any repairs Jerry, or just run them?

 

[1BUS]

hate to see that, yea JB weld or some type of 2 part epoxy, really nothing to lose at this point,

 

[gf beranek]

I run'em, B. I was surprise there were no leaks in the cases. Epoxy would have fixed it. They were company saws when I was clearing right of way. Worn out junk. Wouldn't have been a big loss. We needed a couple of new saws anyway.

Devcon putty seams to last better than JB or quicksteel for me.

Bond-do

Way to leave us hanging, Jerry.

Jerry's post got me interested in exactly what fish slime is. I never realized that it is so important in a fish's biology.

 

[gf beranek]

The fish slime with the salt water was the catalyst to accelerate the electrolysis between the magnesium and the steel. And fish slime does many other things too.

I heard wd 40 was some kind of fish oil derivative. What exactly are those cases made of? We used to use something called Yamabond (made for yamaha) on issues with the cases on motorcyles - prolly just jb weld in disguise.

 

[CurSedVoyce]

Something fishy about those saws......

Can see why your bummed out Burnam. Especially as your saws are so well cared for.

J.B Weld! Our shop's head foreman has even done cracked gas-tanks on the 200t's with it, and we've gotten semi-satisfactory results. The oil-tank shld be no-sweat B.

 

[arborworks1]

B, you really should take better care of your saws!! Maybe they need to be buckled in from now on...

 

[squisher]

I'll throw another vote at jb weld. I think it'd workout fine.

Sand the area around the damage real good then acetone the whole thing several times before you epoxy,bondo or J-B weld it .

If you get every trace of oil off the damage that J-B will about hold forever .If you don't it won't .

Get a piece of a junk inner tube or a piece of rubber matting to put under those saws .

I have thin plywood lining my toolbox shelves. Works great for soaking up oil seepage, and the oil keeps the plywood in excellent condition. Still have all the same plywood liners in all the boxes that I installed 4 years ago when I bought the truck.

 

[Al Smith]

That would work well .Anything to stop the dang saw from slidding to and fro across the steel boxes .

 

[flushcut]

I wanna know how the fish slim got in the tool box. C'mon Unky Jerry tell us a story.
It's a good thing you caught it in time B it would be a real loss to loose a 200 before it's time.

 

[woodworkingboy]

Wonder if the slime had anything to do with hiding an extra salmon from fish and game?

Don't feel too bad Burnham. I have had similar happenings with our 200's only in a different spot. In fact it was just yesterday one of ours got a nice big hole in the oil tank. I had repaired this one before with JB and it broke out just below the area of the repair. It seems the metal either gets thin and fatigued from cutting or is just a design flaw. I dunno.

JB will fix tht no problem. Sand and scuff the area very throughly. Clean the area with carb cleaner. Mix the JB up and apply it feathering it around the edges. You don't want it too thick because it will take a long time to really set . JB doesn't really dry so to speak it is a chemical reaction that take time to go through the mating process, think of it like concrete that needs time to set up. I put a heat lamp over the JB area and let it set a few days before using saw. This helps to cure the JB.

My new 200 problem can't be fixed with JB without some type of patch to go along with the JB. I don't know if I can fix it or start robbing it for parts to make up another saw . That will be todays project.

Alas, I have a brand new 200 waiting in the wings for just such a disater but knowing me I will not sacrifice the virgin if I can get aother saw or maybe two from all the parts I have here. I have another 200 that went down last year not because it didn't run but I can't keep a muffler on it and have tapped out the holes as much as I dare. Time will tell. Good luck Burnham

Larry, wondering how the mesh type material that they sell for auto muffler patches would work with the JB? Some kind of wire mesh with gaps to hold the adhesive.
