I just read all 17 pages of this thread............. I mean Damn WTF guys?!?!?
Port one if you want to. Don't if you don't. For God's sake don't kick me in the balls for throwing my opinion in this mess.
I love to hop stuff up. I enjoy that sort of thing. And it ain't for everyone. I ported a weedeater the other day, even milled the jug and spun a pop-up for it. I reckon it's 67.5% more productive than a stock weedwacker. :msp_ohmy: Hell it was so strong I got scared of it and gave it to a friend. :hmm3grin2orange:
I've been to a few GTGs and have placed my mitts on a lot of builders saws. I've also stood and watched folks with ham hands and no understanding of mechanical things make strong running saws look bad, really bad. You know who you are.
The OPs questions were answered in the first few pages of this mess. A lot of the rest is just BS I would like to say thanks to the real loggers that chimed in with some valuable posts.
Terry Landrum uses a very strong "modded" saw for work everyday without any issues arising from the port work. I do remember his favorite 440 getting smashed when he let another guy run it though. I bet the porting was the problem.
I'm enjoying learning a new craft. I've built several saws now and will be the first to admit that experience is key here. Some of my first porting efforts were not so great. I've got a small pile of mistake jugs in a bucket. I sure ain't afraid to cut stuff up.
Attention to detail, nice slick bevels, and seeking to improve whats there rather than reinvent the wheel is a must. I see that and I've got a lot yet to learn.
I've spent the last month or more learning to hand file better. I've found gains that equal a muffler modd on a epa saw just by learning to sharpen instead of relying on my grinder so much.
Should I kick my own nuts or what???
