OOO, me likey 395's, I've built a few of them now. And still have another in a box to do. IMHO, they need at least 20° blowdown.

Nice work as usual.

What material is that for the mandrel? I should try that next time, but I pretty much have all sizes now in Aluminum.
 
Roughed in.

It's some sorta PVC stuff and stuff.

I like it as good as the delrin I was using.......maybe better.

Looking good as always!

Have you ever weighed a jug before and after porting to see how much material was removed?

I don't have any scales that are accurate enough. I would like to see that though. :laugh:
 
Great work Randy. The more I run that little 026 you did, the more I am thinking I need a bigger one to keep it company.:rock:

Al.
 
Mastermind, im new to saw building, i actually just REbuild now. Mostly Old Stihls and Huskys....just for fun, and to beef up a collection.
Can i ask, whats a woods port, squish band, ect....and what would it do for my MS362?
Im mostly a DIYer, and would try a muffler mod just for the express purpose of learning how to....and then bragging that i DID one...

Not trying to take your business, just looking for knowledge

Ya, I've used it before, but just in flat stock, and I can't remember the name, but it was the same colour as that.

395's rule the roost for 90cc saws. I should'a never sold my last one I did. I still have a runner, which I need to go back in, its not as good, and one in a box. I just hardly ever use that size saw anymore.
