I have a crazy Idea (like most of my ideas) I don't imagine I'm the first to think of this(like most of my ideas). Anyway chainsaws are heavy, I was think'n about getting another basket case saw get it runnin and then see just how much weight I could lose off from it.
The plan so far is to tear it down and see what every peice could afford to lose, smooth out casting lines, etc, Then drill a few dozen holes in the cooling fins say 1/4" dia, feather out some to the structural reinforcement type stuff (buttressss?), I kinda want to drill some larger holes in the connecting rod but not sure how that would effect flywheel balance or vibration... Maybe get real ambitious and thin the inner dia walls of the fly wheel (it would lighten it without affecting momentum to much)
The idea is to make a reliable saw that weighs a 1/2 pound or more less than its stock counterpart. I've toyed with porting and polishing my first time with this project, it would remove material while theoreticaly improving performance...
So anyway full time real machinist (as in I understand how and why of every machine type lathes mills cnc manuel etc) part time gypo logger, so I'm fat but still carry a saw three days a week, cutting metal is nothing new to me and dead reckoning i can figure whats minumum for structure, whats necesarry etc. the part that gets me is will drilling holes in the cooling fins affect their ability to cool the saw, and will drilling holes in the conecting rod make it vibrate out of my hand,
I could just put a light weight bar on it but I'm also a cheap bastard and those bars ain't cheap, so I was planning on trying to make my own. Out of a factory or a "junk" oregon bar(that should start some fights...) thanks for any help
