      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.

Winch Installation Question

Recommended Posts

This weekend’s project is installing two Harken B32 primaries on my Laser 28. Each winch sits on an aluminum base that is in turn mounted on a sloped cockpit coming. Most winch installation instructions require the winch to be oriented such that the drive gear is in line with the line entry. How important is this rule? Due to the particulars of this this boat, this rule may be hard to honor exactly.

It doesn't seem to be that important - I've never found one mounted that way originally on any of my boats. In theory it properly maintains the gear mesh clearance under load.

 

If it's a self tailer the line lifter should be at 5:00 to the person grinding - THAT matters for a cleanly running tail but it can be easily adjusted.

The problem presents itself under high loads. If the drive gear is opposite the load you transfer the load to the wrong parts of the winch and you will see early failures. On winches that have the split ring pins on top, they will bend out and pop off while you grind in if the gear is opposite.

On some winches, the bolt pattern for mounting is not symetrical. If this is the case, its possible the load path will not be ideal and esult in premature fatigue or failure. Not likely unless your really really loading up. I cant imagine Harken 32's on an L28 will be that close to the brink... If we were talkin a bigass barient on an old ally maxi, it'd be a different conversation altogether...
