Fruecrue 660 build thread

How much did that take off? .001?

I kept track as I went periodically.
12 stokes with the fresh paper was about .0015
Slows down as the paper wears.
Then I scribble chit and adjust my pressure as necessary to square it up.

Have you tried a circular motion?

 

[MustangMike]

I go back & forth with minor turning each time (instead of a full 90 degree and one way).

But I just did enough to clean the coating so I could put it down w/o a gasket.

(On my 066 ... did not get my 660 kit yet).

Yes, my granite slides all over with too much pressure.
I use a light circular motion at the end to smooth out any streaks.

That is what you want to see! NICE!

How long did it take to get it down, and what grit paper did you use?

 

[Fruecrue]

I have to go do some things with the tiny people I made.
I need to time the cylinder again. Any guesses where .012" lower will get me?

100 grit, took me 1/2 hour maybe.
Mostly measuring and taking pic/ vid.
I could do it in 10 minutes.
Glad I wasn't taking off .060"

I'll probably leave the #s where they're at. I like a torquey saw.

 

[MustangMike]

Yea, I would, but if you get new #s after the lowering, please share.

 

[Fruecrue]

Will do. I haven't much use for a 660, so this saw probably won't see many hours or extended run times. If it builds excessive heat, I may consider raising the exhaust port. If it's too slow, I'll run a larger sprocket.
Any of this is subject to change at any time.

I would take torque over a fast peaky saw also.

 

[Fruecrue]

Checked timing after .012" off the base.
No signifigant change. 1/2 degree maybe.

Good info here, I'm gonna look into my carb today as well.

So a couple a dudes who know chit ( @mdavlee & @Redfin ) said they would run at .016" squish, which is always an option.
How much compression is too much?
Keep in mind this saw has no real world use or life span expectations. It can be considered a race / play saw that is expendable.
saw is still apart, but not for long.

220 plus would be what I think is too much. 180-190 will live longer as a real work saw.

I doubt you will get over 200 without a pretty good squish band cut

Probably not. I think the cross jug has pretty good compression with a gasket delete.

Final port work. Will assemble tonight.

I gotta say, I love this chit!
Always more to learn, great people and a great place to learn, a million different ways to do things, just plain fun!
