Mast Tang installation

[Brion Toss]

Hi again,
Oh, good, that is good to hear. Getting back to your original question, then, properly-made tangs will not weaken the mast, and are less likely to cause decay and tuning issues. So, much as I like soft eyes, there's nothing wrong with moving to tangs. The big thing is to provide adequate distribution of load, with things like "finger" extensions, and bushings around the throughbolts. Let me know if I can be of help with the details.
Fair leads,

My biggest concern was the through bolts. Are there any examples of tang styles online that you know of? If I do use them I envision long finger extensions, meeting at a plate where the bolt is placed (through a sleeve), then extending to the double clevis hole.
I don't know if that paints the picture but is it what I have seen on some other masts.
On a 7" diameter mast, what should be the maximum or necessary bolt diameter?
Thanks

Hi again,
Bolt diameter is relative to shroud load, not mast size. Same bolt size as clevis pin is a rule of thumb, unless there are two shrouds on one tang (like lowers). What do you mean by "double clevis hole"?
As for images, look through the ones here:

Note that the tangs are independent of the backing.

Sorry about the double clevis hole thing. I just meant the receiving end for the clevis pin. Which brings me to another question. Is there a complete book of boat part terminology...for dummy's ...available anywhere? I've tried googling but can't really find white I'm looking for.
Thanks..Kevin
