Sorting through a bunch of old chains. Someone told me that there are certain ones that are attractive to guys who make race chains, compared to newer models. Anyone familiar with this? Any brands or chain models I should keep an eye out for?
Thanks.

Thread on it here already. See if I can find it later.

Philbert, you need to go with the Oregon no AntiVibe or Stihl no Comfort. 1 barb arrow on the Oregon cutter and C on Stihl is what you need to avoid.
These chains came out about 15-20 years ago.

I don't plan on making any race chains, but would pass them on to others if I run across them.
Why is anti-vibe bad in this application?
Thanks

Old thread http://chainsawrepair.createaforum.com/chain/oregon-72lg-and-76lg/
I know the game has changed today by a top notch hand filer. But this was what we looked for in past.
I have a oregon 76 76DL chain here now if somone wanted to trade me a regular chain for it so they can use for their chassis. Cant recall if it is a LG or SL. LG just make it easier on them for side parts.

Same reason why new Stihl .404 high tooth has no antivibe "Comfort".
Picture shows even amount below rivets on both heel and toe of cutter.

I understand the physical differences, but not why it is a disadvantage for race chains. Trimmed heel would also be less weight

I don't know what you're getting at with a trimmed heel for weight saving relating to a antivibe heel....
A race chain is modified all over to save weight, to increase chip clearance and flow.
But when you have a chain where its cutters have built in "shock absorbers " with a space between the bottom of the heel and bar rail, the cutters don't enter the wood as firm and aggressive as it would when there is no space between the bottom of the heel and bar rails.
Sure for a work chain there is less vibration and you won't notice any change in cutting speed. But the differences in cutting speed with a race chain can be measured in 100/ths of a second with a stop watch.
Reason why Stihl never put Comfort cutters and side links on their .404 high tooth timbersports chain.

That's what I was looking for.
