Change out the clamp at the same time. New one is steel vs aluminum. Also need to flip that clamp for the longer spring.

I tried both ways and stuck with the position my original clamp was in . Worked the best for whatever reason. I did install the steel clamp. Much stronger than the original.

FYI guys I did go back and flip that clamp around, spring was starting to come out of socket from being pushed too tightly during movement. I was bored and decided to widen the intake and exhaust a bit. I also did the “solo” mod to the lower transfers that mike lee mentions, in addition to my previous mods to the saw. I’m happy with the gains and will see how it holds up.

Solo mod?

The 681 comes from the factory unshrouded.

Would you say it's your favorite saw?

 

[Rob Stafari]

It is by far my favorite saw! Almost got another running craigslist 6401 for $200, but a rain delay made me late...

Stock or ported Rob?

In that class yes

Thanks! Still has the black coil found on the early saws, 13.5 limiter. I have it tuned about 1/4 turn past the limiter.

FYI I’m not claiming to be a saw porter or professional. Just having fun here. You never learn if you don’t try it.

thats where I ended up too, I want to do it myself and learn and make it all mine.

I am having the squish cut by someone with a lathe but I cant help that. I dont have a mandrel either.

 

[huskyboy]

I’m surprised with the compression these saws have without a base cut. Easy 185psi ish. I can only imagine with machine work. That said, the decomp works great on these, easy starters.

All stock around. The two newest to me basket cases are still 6421s. Figured I'd trouble shoot and make sure they're running right on the top ends they have before upgrading. So far so good...

Super nice Rob! Gorgeous pieces you are milling.

 

[Rob Stafari]

Beginners luck. Some of the first pieces I milled. On the lookout for more like that!
