sedanman,
I once put out a question on another forum concerning "full house" chain. For people that don't know what a "full house" chain is, it's a chain that has no spaces between the teeth, just tooth after tooth. It received several responses stating that kind of chain is used for cutting aluminum. That wasn't my question at that time. My question went something like this: for discussion purposes, if you you took a modified 090 Stihl, put a 20" .063" gauge bar on it, then put a modified "full house" .058", 1/2" pitch chain on it and made a cut in a 17" round log. Would it cut faster than a full compliment chain that was modified to the same degree or would it bog down with sawdust because there was no spaces to carry out the sawdust? This is a good question for all the experts out there to ponder over, especially those that prefer full skip, semi skip or even full compliment chain to comment on.
