.055" off the Echo, and .043" off the Stihl.

Are these similar to the Dolmar 5105 or completely different?

That Echo cylinder looks to be of very high quality judging by the pics

I realize this is an AS type of question, but once you have the cylinder slid onto the mandrel, what actually drives the cylinder to keep it from slipping while you are turning the base? Also, is there a point on the top of the cylinder for your tailstock mandrel to engage to stop the chucked mandrel/cylinder from whipping?

The top off some of these jugs are tough to find a way to set a live center on. The 362 jug ain't as bad as a 562XP....but it's not just a flat surface. So.....

Fire away with the questions Chris.

The threads are so much better when people stop worrying about whether or not their question is a good one or not.

The pressure I put on top of the jug with the live center is what keeps it from slipping. I only take .010" off on each pass so there's not too much resistance.

That's great - thanks. I learned two things today so I guess I can take tomorrow off.

 

[dustinwilt68]

Good question, I wondered the same thing.

 

[CJ Brown]

I don't usually have too many questions because you builders are always so thorough in your threads, not too much is left unmentioned. OPE is definitely a builder's forum (at least from my perspective), so I don't post here much because I don't bring anything to the table.

But I truly enjoy this site and read it pretty well every day.

Well we're glad to have you Chris.

Thank you for the kind welcome!

Now back to the build!

When you do a lot of different saws.......it's easier to make up a timing pointer for each model.

Squish on the 362 landed at .022"

The numbers on the left are where the port heights are after machine work. On the right are my target numbers.

Damnit they both can't be on the left

Whut?

I've been adding the dimension from squish band to top of port to all my porting spec sheets. This is how it looks on the MS362.
