Inside the Exploded JMS 064

[Time's Standing Stihl]

Exactly the hysteria I was referring to.

Lol, I pulled the one out he "lightened" for me, got a new meteor and went even farther.

You seen muh fancy grinding skills

Thats flirting with disaster in a worksaw IMO!

In other words...

To make an omlet, you gotta break a few eggs.

But nobody wants egg shells in their omlet.

I like flirting....can't be scared, if so you'll never leave the house.

It might go boom and it might not. If it does, hopefully it will be on video. I'm not going to lose any sleep over it.

Just for an example...
Meteor 395 piston

Modified for a work saw. I've never had one come apart.


As far as I've gone with a stock 395 piston.

I went from 96g to 80. I just didnt feel comfortable with it

A
Some people have even said they think Brad blew it up on purpose. I'm not sure a more insane theory has been floated yet, but that one is the reason I'm sorta annoyed about the whole thing......

Wow. That's ludicrous. I don't even want to know who said that! First of all, I would NEVER do something like that, and I think any logical person would know that. Besides, I would have nothing to gain with such a stunt.

Most I've seen ingested something .However one my BIL had,a 10-10 Mac he tried running it on 20 percent nitro and aviation gasoline some 30 years ago .Poor old Mac just gave up the ghost .I've got that piston BTW .Brad would not have sabotaged the damn saw now .What kind of BS is that?

 

[Al Smith]

As far as a hone goes I don't use them .I've got a Lisle precision hone with the hard stones to do plated lining but all I've ever done with it is size the cast iron liner I made for a 125 McCulloch some years back .A stone or brush hone cannot remove ovality or taper,a precision hone can .

I agree! Thats just silly for somebody to think or say that

+1. When I see your posts, all I can think of is JMS giving you all that crap about your 390xp.

Why do you think that Keith? How much is too much?

 

[blsnelling]

I used to lighten my pistons but haven't in years. I never had one fail, but don't see the advantage. All I do now is clean them up if needed.

 

[Mr. TBE]

Hi I'm new here so I'm having a little bit of a hard time understanding what happened here.

OP, you took the saw (partially) apart to take pics but did not bother fixing any of the problems?!? And then pinned the throttle till something let go while you happened to be videoing. Why???

Yup, that's it. You're a bright one!

 

[Mr. TBE]

* sorry if that sounds accusatory. I know that is frowned upon here.

I had a feeling about you. Just here to stir the *s-word after all.....

I'll be pulling your plug.

Mr TBE was from Maine........

Looks like it was probably Mike/Goat/whatever.

Why do you think that Keith? How much is too much?

Common sense tells u if u take too much out it will fail? How much is too much? Not sure. Take enough until it fails. If somebody tells u that u can lighten a piston and it doesnt weaken the structure somewhat Id say they r full of it. Just because it hasnt failed doesnt mean the makeup of the casting hasnt been compromised to a point? Id agree that taking enough out to smooth and contour the windows and edges would be fine but theres definetely a factor of too much but not sure where thats at and the small amount it will make on a worksaw isnt worth ruining a saw IMO

I agree Brad. Especially in a work saw
