I intend to build a pair of wheels. Never done it before but I fancy having a go. I've read several articles and for simplicity Sheldon's page is the one I'll probably follow. I've looked at the spoke calculators and feel happy to use them. But, after using these to determine the correct length it occurred to me that I'm unsure where the spoke should end at the rim. Is it flush with the inside of the rim or should it enter the rim slightly? Is there a rule for this? I feel daft asking because I've replaced plenty of spokes in the past on different wheels and none are consistent - as far as I can remember. I really don't want to make a mistake. Or does everyone use a calculator and just go on trust?
