MS880 + 3/8th

[Maico490]

+1 on the last post. Drive link gauge has nothing much to do with chain strength as the actual links are all the same with just the lower part ground down. The biggest difference will be between brands. Also 0.050" 3/8 chain isn't easy to find over here. Go to the West coast of the US and they hardly use anything else.

Think we are all getting a bit confused on the points Alec was making: -

 

I believe he is saying the chain gauge has a baring in the strength of the chain.....

 

The chain "gauge" is the thickness of the drive link, the side plates are also of the same gauge steel and therefore a 1.1mm dl is weaker than a 1.3mm that is weaker than a 1.5mm that is weaker than a 1.6 etc.

 

The chain "pitch" will have little baring on the strength - a 0.325 1.5mm should have similar strength as a 1.5mm 3/8" chain - probably in reality the 3/8 will be stronger due to less links!

 

I think this is the point Alec was making - sure he will confirm if he is about!

no, i think we are all getting a bit confused as to what gauge is....

 

The chain 'gauge' is the thickness of the lower part of the drive link, the part that runs between the bar rails and contacts the sprocket, not the entire drive link.

Yup - that is what I said...or meant:thumbup1: to back this up, I have measured a number of chains and can confirm that the drive link gauge or thickness is the same thickness as the chain side plates/links - so a 1.3mm drive link chain will have links that are 1.3mm in thickness etc

I don't think so... How are you measuring the tie straps? On an assembled chain or loose replacement tie straps?

 

For example Stihl 0.050" (not narrow kerf or low profile) and 0.063" chain use exactly the same tie straps, left and right hand cutters. The only difference being the drive link. I suspect 0.058" follows the same principal also.

I checked a 1.1mm Stihl chain, a 1.3, 1.5 and 1.6mm (don't know the make) chain with a set of callipers - wasn't an easy task but the thickness of the drive links pretty much matched the thickness of the side tie as far as I could tell, the chains were loops and not the links for making up loops - I am thinking that perhaps these links are different thickness but may look in to this further if I get time.

 

I am sure that the ties were not a different thickness to the drive links but perhaps Stihl are different from others:confused1: I may investigate further and report back - just reporting what I find and measure, too tired to argue to be honest:lol:

 

I can state that the chain on my 3/8 Husky 181 (80cc) is a tad stronger than the 3/8 chain on my MS170:001_tt2:

I can't see how you can measure a tie strap on an assembled chain without having to "tilt" the calipers.

 

Counter example;

measure the width of the chain across two tie straps, fairly confident it will be less than 3X the chain gauge on a lot of chains. Hence, tie straps not same gauge as drive link.

 

Also worth noting though some drive links are thicker at the top than the bottom and tie strap etc dimensions will vary between manufacturer.

 

Not detailed enough to draw any conclusions but a cool picture anyway. 3/8" PMN on the left to 1/2" on the right;

Right - just back from a 2.5hr drive from Telford, had a big slab of chicken pie and can confirm te following: -

 

Traffic good

 

Pie was nice - good chunks of Chicken and Chorizo

 

1.1mm chain has 1.1mm side tie straps

1.3mm has 1.3mm tie straps

1.5 and 1.6mm chain also has 1.3mm tie straps

 

The 1.1mm chain was stihl and the other three Oregon - other manufacturers may well be different!

 

My calipers are 6" with a pointed jaw so I can fit enough of the jaw between the chain to measure it.

 

Probably get someone commenting about my pie now:001_rolleyes:

 

Hope Paul got his bar and chain sorted:thumbup1:

 

Can we say

You can't beat a good chicken pie!!!!

Yup - veg out of the garden, a bit of mash and gravy - nice:thumbup:
