Default Eye sizing

Hi all.

I am in the process of replacing my rigging, and was interested fo find this nugget of wisdom from Brion Toss in his 'pieces of string' series:

http://www.briontoss.com/education/a.../miscoct98.htm

Clearly a small deviation in pin size to hole size can cause some serious woes. What this article doesn't touch on is the appropriate sizing of the terminal hanging on the pin. For example, If we have a toggle at the mast head with pin diammeter of 10mm (and therefore pin of ~9.9mm to avoid point loading), would the eye that it held also have to be ~10mm, or does it matter less?

Any insights welcome; I'm stumped - and a beginner:-)

Thanks for any info
Adam Tait

Point loads are bad wherever they occur. All pins and holes need to fit, regardless if it is a tang, fork, or eye. The pins should fit in the holes per the spec that Brion mentioned in the essay.

I agree with Bob that all the holes must be the appropriate diameter. Oversized holes can sometimes be filled with a bushing of the same material.
