When a chain is put together and the rivets expanded they expand back beyond the tie strap sides. They will take a little effort to remove the tie strap even once the rivet heads are ground off but on that chain even the tie straps have been ground thinner, I myself would stop when the rivet heads are flush with the tie strap sides, some dog boning is ok, this all helps with reducing the friction between the chain and the wood being cut.

That's racing. I've seen chains that I just shook my head at, but in the wood were fast. It's all about experimenting, and finding out what you can do to something off the shelf to make it the fastest it can be. To be the fastest you have to take it to the edge. That point right before everything goes to :censored:.

Red, I know you have some pics for us!:dunno:

$65.00 and have sold over 400 of them.
That's basically how the chain owner put it. It's kind of like a crank and flywheel, since there's a taper there.

$65 a chain and all you do is grind the back off the cutter? As far as the sharpening side of things goes there is nothing special there, in fact it may not even cut any better than a stock chain with what is quite simply a standard round grind job. I can go out to my grinder right now and therefore turn a $20 chain into a $65 chain in minutes. Twice as fast as a standard chain without touching even the raker height and still having it round ground?
400 sold you say? Hmmm...
It also looks like the top plate angle has been changed. It looks a little steeper like 40* instead of 30-35*
I agree sometimes it is surprising how well things work despite their looks, but having an ungly chain be a real fast chain is very much the exception to the rule.
It is like port work, a rough port job with good numbers and tuning will still look fast when run against a stock saw but when putting that rough porting up against a saw with good clean porting work and other factors being equal the rough work loses. Same goes for chain, to be fast every cutter needs to cut at maximum efficiency if even one tooth is off the whole chain will cut less efficently and the stop watch will run longer. If you can look at a chain and see differences in angles and the shapes of cutters one tooth to the next there is no question that each tooth is not cutting at its personal best and hurting the chain as a whole.
Could not agree more, "the fastest it will be" is so often the point right before failure... endless compromise between fast and reliable.
Plus, you could end up with an Art Martin, "decoy" chain like I did or a Walt Galer 15 minute chain. lolGreat thread guys but I find something inherently immoral about buying a race chain.....
.....make the fastest chain you can.......and be happy with it.
Great chain photos!
Red, on your work square ground do you every lower the rakers below .025 as the cutter gets shorter.
On mine I'm using a feeler gauge and .025 even tho the cutters are well back.300 or longer gullet and it seems to cut well.
I suppose it depends on type of wood and the saw,just wondering your opinion on it.

Remember the "Great Chain Race" thread.

I think it's better to go .020 and play with sprocket size instead, but I'm just a GTG'er. Lol.025 is about as low as I ever go.
