      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

Carbon Boom Attachment Points

Recommended Posts

Ok gang, I'm looking at getting a carbon boom done here. It needs some attachement points for the vang and mainsheet. I'm looking for pics of the molded glass bit that sits on top of the boom, that you can pass line through, and tie a block to the boom. Having a bit of trouble finding them.



Many thanks!!

Here is my boom during the construction process. The carbon bit in the foreground is the one my brother made for the main sheet block attachment. The one in the background was installed by Larry Tuttle at Waterat.

Carbon, did you experience any issues with running a line rather than a strap? A lot of the advice I've heard is to avoid lines as they point-load the spar. Or does the base of the installed parts take care of spreading the load around?

If you use rope for the vang and cross the lines on top, the lower rope makes a hard hard point and compresses the boom. I have a broken boom to prove this is not satisfactory. Loose weave ropes which lay flat seem to be OK though.

Agree! My I14 has a strap for the vang and spectra loops for the mainsheet blocks. It's the original boom from the 2000 Bermuda worlds...
