Saw builds

[Canadian farm boy]

Those are both very impressive saws. Nice work J.

Both are at 14000 but his is turning more in the wood because I can kinda let mine self feed but his wants to scream so i cant keep from prying on it to kill some rpm.

Nice to see you making a strong saw doing it in a totally different way.
Raises some questions now...

Yeah...... Why?

Transfers are different but everything else is the same.

 

[paragonbuilder]

All this talk of case capacity and tight transfers for velocity, seems to be irrelevant. What really is making power?

I guess flow and direction will trump velocity at some point.

The saws I build using velocity are very close to these and take a 1/4 of the time to do. Lots of ways to get the same results.

I will say that my 066 that Shaun ported feels violent and the one I did is very smooth so mine feels way stronger but it's not. They feel completely different.

Either way makes power so which ever way you like the best I guess.
If you like grinding go with flow and direction but if you don't use velocity.
I think flow and direction makes a little bit more power. Maybe

Does one way feel free'r than the other?

I think my 064 runs more free

I think the anger comes from the transfer port stagger I run. Yes, it does take a long time to make a cylinder that light.

That will be the difference between the two, mine open on the intake side first.

Here's the half video I couldn't complete cause I didn't bring a wrench to change the bar.

Hey j....look at the pile I just found...

 

[Mattyo]

Anyone got good numbers for s 394?

Stock squish now is .050 with gasket. Gonna go mill off 30 thou from the case...then see where I am at for numbers. Don't need to cut squish....don't want to go crazy.

Cylinder had some transfer but it's quite clean now.

Here we go!

100 120 78 is always a good place to start.

 

[Deets066]

I'm gunna try 102 - 124 to start with my 394

 

[Deets066]

@srcarr52

What's your thoughts Shawn?

 

[srcarr52]

I'd have to check my notes but I think most of my 394's ran good around 158-160 ex duration, around 18 degrees blowdown, intake 4 degrees below square. Someone can convert that to opening timing but I think in duration and relation to ex timing.

 

[Mattyo]

hmm... maybe 102, 120, 78 for me then.... to combine everyones numbers hehe.

i'm on it!

99-117-78 or so
