Now that the jug is done I'm gonna work on the cylinder base. I want to make it match the base of the jug to keep things flowing nice & smooth.

I removed some material that was in the way.

Taking bets on how many rpm's it'll turn no load...
Put me down for 15,600... :msp_wink:
Anyone else???
Don? wanna venture a guess?
 
OK now back to saws.

Here's the finished jug

Do you modify a stock intake boot to match the opening on that, or is the stock 357 boot that much bigger (better)?
Nice work so far, I've thought of this mod many times but always find something else that gets my attention.

It's real close the way it is.
 
I believe it'll turn that much and still 4 stroke, but bet Stump will tune it to 14,800... :msp_wink:

12,800 in wood??? :msp_biggrin:
There's just a couple things about this build that are a little different than normal. From the case to the carb to the oversized jug... This should be interesting... 220+ lbs of compression if the squish is under .020.. Just a guess of course...
:monkey:

I'll give it what it likes.:msp_wink:
I don't really care what it turns no load, just hope it turns at least 10,500 in the wood with a 20" 3/8 like the 346 I done last week.

Squish is @ .025''.
 
I think I said earlier that I would have a total weight loss after grinding. So here it is. This is for you SawTroll.:msp_wink:

Cylinder
461g
425g
36g loss

Cylinder base
107g
96g
11g loss


Flywheel
276g
264g
12g loss


piston w/o pin & ring
57g
54g
3g loss

Total weight loss
62g
2.187oz

No surprice there, as you removed a lot of metal. :givebeer:
 
I want to show the difference in the size of the 346 & the 357 carb mount.

To make the 357 mount fit nice & tidy in there I cut the end off of it.

At first glance nothing seems out of the ordinary for a 345.:msp_thumbup:

While I was in there I upgraded it to an adjustable oiler that came from the same donor saw that the cyl base came from. Te only thing needed to do the swap is to pull the old pump out & also pull the pin out. Then in goes the adjustable pump.

All I got left after that is the muffler. I installed a 346 muffler bracket to help support the can.

I had to trim the rib where the screw is on the recoil side. The screw I used was a coarse thread wrap handle screw.

Got the shroud fabbed & welded on.

Due to some interruptions I was unable to put this thing in any wood. I'll get a vid of it tomorrow. :msp_thumbup:
