#25 Chain is THE way to go

Now many of us may have our opinion, but remember - everyone has an opinion. Out of all the individuals that have responded to this question, Raul and Joe J. are by far the most reputable of individuals - no disrespect is meant by this comment, but lets remember the machines/marvels that these two men have created during the past 5-7 years.

I tend to side with Raul on this issue. Team 302 has always used #25 chain - even for drive train. Last year, we pushed some mega forces through that chain and we only suffered one problem. We had two small sprockets (for our jackshaft of the drill motors) that had chain wrapped too tightly around them. The machine still ran beautifully, but at the end of each regional we found that there was a slightly seized up link. This was our mistake, not the chain's.

I always am one to play it safe and triple check everything, but #35 is unnecessary unless you are really pushing some mega mega force through that chain. A good example was the guy (above) that said he had problems with #25 with six motor drive.

I know that Raul last year pushed some EXTREME amount of force through that chain on his wedges/wings. In fact, he geared down each chiaphua to approx. 40 rpm's and (like he said) he used #25 chain with no problems. Using #25 is not cutting any corners, but just simply saving some weight.
