 I once heard someone say that Dean is "building an army of engineers." I disagree. I think he is building an army of the informed. - Gope [more] |

Re: pic: FRC294 Prototype base almost done
Adam,
it looks really good, the machining is obviously top notch. I am wondering if you have put any thought into the amount of chain wrap on a sprocket? best rule of thumb is that you need at least 120 degrees wrap on each sprocket, I have a feeling that the center wheel is just about at 120 degrees. If you have the option have you considered moving the idler on the bottom left towards the center wheel which will increase the wrap on the center while keeping your left wheel with plenty. Greg
