Is Anyone Interested In Seeing How I Port A 372XP

[o8f150]

Do I mention that I've tried hogging the transfers out before?



This jug is from a saw that hung a ring......:msp_unsure:

ouch

Now the exhaust port is another place that I spend some serious time on the 372. Again....I've tried a bunch of different stuff.......but the exhaust height at 100 - 99 degrees from TDC seems to work reall well on the 372 when it's main propose is to pull a work chain.

There still has to be a bevel and some polish here. I use a 1/4" diameter diamond stone in my RT angle to do the bevel.....and varying grades of Scotchbrite for the polish on the port edges.

ouch

Whats up with the goo in the right-hand jug? Some of that technoplate whatever?

Sorta tough to see but there's a step in the floor of this outlet. Terry Landrum first showed me this in an XPW he had......that saw was a bad dude.



I've done it with and without this step.......but I think it makes enough difference to be worth the time.....

I sure don't know everything, and would love the hear opinions, ideas, mild criticism.

You are humble, admit that there is more to learn, and have such a level headed approach to your builds and the way that you present them on AS- I think that is a good part of the reason you are well respected here IMO. I don't ever remember you carrying a "better than thou attitude", or demeaning anyone looking to learn. I feel like I have learned quite a bit from you, just from reading and watching your work intently in these build threads. I think many of us have. I'm not butt kissin' here, but I think there are more than a couple reasons guys here are keeping you working around the clock, and your attitude is probably #1.

The transfers I think are where you can either build a saw that has that WOW factor or one that is just OK.......on the 51.4 mm XPW jug I set them at 122 degrees from TDC for a BD time of 22 degrees.

I forgot to mention,, that is the same big maple log,, there is a big difference in cut speed,,, I get a stiffy everytime I run it

Hay Randy, can you do some port work on an aftermarket BB kit on a 660?

On the intake I let the lowering of the cylinder determine the duration. The way I cut the squish and lower the jug I end up at 80 - 82 degrees. I don't do a lot of widening on the intake on this model because I would rather not add any more time/area to the port.

I've yet to find a BB 660 jug that I like Sam.

I gotta sign off for a bit........be back later.

This is something I've been wondering so I'll jump on this hijack. Is porting and aftermarket jug generally not a good idea? I seem to remember reading that somewhere but don't remember where. Is it a waste of time? By the way, repped for a good thread and something worth reading lately.

 

[shoe601]

Randy I don't know if this is how you did the 375 I bought from you but it sure cuts. It's been so hot I've only got a couple tanks through it but its one hell of a strong saw. Thank You.

Depends on the kit. I've got a ported Meteor kit on my 372 done by Randy and its a strong work saw. 24" with an 8 pin all day in hardwood.

Back on topic to see how he chews on cylinders.....

that about sums it up. Plus he has the coolest username/ sticker.:msp_wink:

There's 13.2 grams of chips in that pile.......I figured it would weigh more.

Maybe you should be pricing your port work by the pound. Just sayin.
