Chain differences

[mdavlee]

Full skip is slower as there's less cutters to do the work. To cut as fast you would have to gain 1/3 rpm in the wood to make up for 1/3 less cutters. It can let a saw turn more rpm in the wood sounding faster but removing less wood. It will dull quicker since less teeth are doing the work. It does sharpen faster with the less teeth. It's all a trade off somewhere.

Full comp plugs up in fir and cedar here ,the full or semi skip helps clear the chips when running a longer bar also .

I think it would make for some interesting test cuts. Wonder what the difference for say a 353 with a full comp 18"..compared to a skip 20"?

When I first joined a site like this, spring of 2015. I had someone argue that I'd spend more time sharpening with a skip.

I said, no the same number of saw teeth hit the wood.

With skip chain you sharpen Less Teeth, but more frequently; as opposed to sharpening More Teeth less frequently.

The math must have hurt his brain because he just couldn't get it. I felt bad being the new guy pointing out simple arithmetic..... the same number of saw teeth hit the wood.....

I have never noticed one lasting over the other ,debris usually dulls my chains .

My Dad and I run mostly all 20" bars with .50 guage 3.8 pitch chains. All Oregon. We run file and cut rakers. Is there a faster chain on the line? I mean is there a brand thats better and faster cutting for staying with a round file? Ppl claim a Stihl chain will cut faster, I think personally its on how good the guy sharpening the chain is. I want to stay with the round file. I'm going with a 24" Oregon and chain, what will get me the best quality but stay at a decent price?

Your best deals on chains are (Internet) by the roll, saving 25-50% over retail loops, sometimes more on clearance. Next is multiple loops by internet, as 6-10 chains ship at about same cost as one loop, and then divide shipping by number of chains. (Sometimes), free shipping on 10-loops. Check that out and then talk w/ local dealer and see if they will bargain on rolls/ or multi-loops? LP chain is (maybe) another option, seems to me it would work without changing bars/ sprockets, but (some) have said it does not fit a 3/8-050 sprocket. (Some) have told me you have to change drive to a new sprocket, due to wear differences. I have not checked myself. I have never seen a "3/8 LP drive sprocket"? (My thought, tho' maybe wrong?) is that if running 7-tooth w/ reg chain, could easily run 8-tooth w/ LP? I COULD be totally wrong on the LP, just never played w/ it to try on my bigger saw?

++++ I BEG to (explain). Skip tooth= less teeth in the wood at any one time (15-50**%??)= (Cutters per foot)= HP per Tooth = (Skip/ Half-skip) HELPS MAKE UP for horsepower AND (some will argue) especially on long bars, = More room between cutters= better for chip removal. Additionally, it may take same number of teeth hitting wood to cut a foot of wood at 0.025/ cut, but (w/ skip/ half skip) fewer CUTTERS hit per revolution of the chain. HOWEVER, if (your) saw/ chain/ clutch are "bogging" / running slower due to drag, skip (might?) help you keep it moving at optimum speed. Something to think about. (**GRANBERG STYLE REMOVES TWO cutters for every pair). p.s. I say Granberg, but (wonder if) it is really Malloff patented?

Lo pro is actually longer between dl than 3/8" by a little bit. It will work on regular sprockets but shows funny wear.

I think he meant the same number of cutters end up doing the work in the end.

I was ONLY talking Sharpening.
I didn't say no nuthing about no Cutting

Not a problem, I had a good time answering

Anyone ever heard of Oregon 76LG?

 

[Canadian farm boy]

Nope

 

[Canadian farm boy]

What gauge is that?

 

[concretegrazer]

Anyone ever heard of Oregon 76LG?

Wasn't it a 3/8l.p. cutter on a 3/8 chassis?

 

[Homelite410]

It sure looks that way!

76lg top 72lgx bottom.

What length full skip? I had someone (off the net) tell me any full skip below 24" was pointless. ..... I'm not sure I believe/agree with this. I had thought it would depend a lot on the saw, because the full skip is making it easier to move the chain, but making the saw run longer to do it.

I'd love input.

24 up to 32 I use it on my 70cc up saws

do you think skip chain or half skip would be pointless on a 16 18 20 inch bars?

 

[Gary Courtney]

do you think skip chain or half skip would be pointless on a 16 18 20 inch bars?

for me it would because I run those bars on my 50 cc saws for limbing

 

[Homelite410]

I have ran half skip 3/8 24" on ported 2260 and I really liked it!
