Let's talk race chain

[RI Chevy]

Makes sense Dave. Thanks. [emoji106]

 

[Hedgerow]

Those are my favorite.

They are at least of good quality.
Swiss made.

 

[Wolverine]

I agree w/ Dave’s post. Rakers are the last step in tuning da chain to the ph.

 

[Willard]

I free file my work chain D.G.'s but a race chain I'm OCD.
I use a feeler gauge and a hard plastic straight edge. Plastic doesn't hurt my razor cutting edges.

 

[Hedgerow]

I just use The Force...

 

[Willard]

Gotta allow for polishing those freshly filed D.G.'s too.

Race Chain Testing Session #1
poplar 8x8 - first cut was a biscuit to get rid of a knot before the cookies
I am gonna use Mutley as my test saw and a 20" Sugihara as my test bar since most of my race chains are 72DL.
Mutley is a freshly built ECSaws, OEM 56mm Millenium bored and plated MS660 cylinder with a CCC Racing Wiseco 56mm BB660 piston, running a WG carburetor on regular gas with a dual port muffler, no air filter, plenty of power to pull any race chain I throw at it

First Chain is a fresh arrival codename D1 - I will try to give the same three high rez views on each chain we test.

and yes, I did forget to tighten the bar oil cap and it dumped a tank on my boot LOL
cut times in seconds: 1.43, 1.2, 1.23

Depth gauge.
I guess I should say raker like everyone else, Lol.

That saw rips Dave! Even vibrated the oil cap right out.

Nice Dave!

The teeth do some raking too while cutting, more important to gauge the depth of the cut, so DEPTH GAUGES

I filed alot of bow saw and crosscut saws in my day, so I kind of got my terminology sorted out. Lol.

A depth gauge can be made into a cutter.
I once modified a 72LPX chain by filing the cutters back to the rear rivet, thinned out the depth gauges so they sliced 2 thin kerfs. Then used the safety drive link ramp as a depth gauge. The cutter bit was then the true raker and cleared out the chips.
Actually cut pretty good.

Was that the EC 66 that you shredded the plating on tryin out chrome rings?

 

[Definitive Dave]

lol slacker

not much of a looker but it runs real nice, I will get it cleaned up with covers to compete in 6 cube stock appearing this year, I think that goofy ass muffler cover came from the haul of parts I got from T-bone a few years back LOL

yep, that's one of the guinea pigs that got destroyed, it got more porting, replated, a new head, a new intake and carb and a new piston since then, I think it runs pretty well, i'm going to try to put enough time on it to get the ring to seat nicely before I pass it around at GTGs
