      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.

  1. fillers - does the hardner go bad

    Please note the fillers/ putties shown here are polyester resin plus a filler: sometimes thay can be remixed and still be useful. Check with a small batch + new catalyst. The putties need new catalyst which is methyl ethyl ketone (MEK= a solvent related to acetone) with a small amount of benzoyl peroxide as the activating catalyst. MEK evaporates from an opened container, especially after years.
  2. Take a look at the A-class racers with C-boards and fins on the rudders- this was several years ago before full foiling arrived. Glenn Ashby and his OZ buds were really good at this: Full sail with power aloft, heeling the boat to go downwind fast on 1 hull, and almost Never pitchpoling. Doing The Wild Thing. And it is great fun.
  3. scored a 50$ hobie cat

    Nobody mentioned- seal the H16 mast. Pop rivets used to have a little can around them, and thus were sealed. Everybody else--- seal the around ALL of the pop rivet holes with Sikaflex (better than 3M 5200). If rivets are loose, drill out and replace them. Shrouds and forestays want to be new and in good repair. (plastic covered wires RUST inside and thus are not good for long (or short) voyages). You can sail a Hobie16 a long ways in a day, so forget the motor. The rudders, pins and hardware have to be drilled properly to have the rudders at the correct angle under the sterns.Then they 1. lock down easily, pop up if you hit anything. 2. avoid weather helm. Practice capsizing so that you are sure of how to not die out there.
  4. Experiences with G-flex

    DDW shows why it is good to actually read tech notes and reviews: Plexus certainly does say it is "methacrylate", and it has a shortish shelf life: To another questioner- Polycarbonate "Lexan" is mentioned as glueable! This is a first to me. I was given a 25 year old, nearly full gallon can of West epoxy--it still looked and worked ok with fresh hardener (the amine), but I used it for non-critical repairs.

  6. Experiences with G-flex

    http://epoxyworks.com/index.php/patch-holes-in-aluminum-boats-with-gflex-epoxy/#more-1526 For BobBill- these repairs are on an aluminum canoe. Maybe like your 6061 aluminum patches?
  7. Bora gulari nacra 17 incident

    Clean, thanks for following up on this. Bora may have had the skin pulled off his fingers by the wrap of traveller sheet. This could just as well happen with the mainsheet wrapped around your hand, in a violent capsize. I think they call it after "debridement" with burned skin. Following from a skin graft article... "Any skin graft must be protected from further trauma, such as being hit, or heavy stretching for at least 2 to 3 weeks". Nobody needs this traumatic damage. Owie. This is not just a blister. This is a serious injury, probaby much worse than when Randy Smyth got a nasty antibiotic-resistant skin infection from a rope burn on his leg halfway thru the 1998(?) Worrell 1000, winning the race and going straight to the hospital for IV drug treatment. Kevlar gloves here we come! My $3 Harbor Freight black rubber gloves are good for ???
  8. Krylon Fusion... on PVC dinghey

    1st off--weight is your enemy. You already know this. So- 18 foot A-cat hull for the ama, weight about 40 pounds. No planks of mahogany- insane, unnecessary idea. Weight is used as ballast like on all cats sailed these days. Randy Smyth successfully sailed experimental rigs 20 years ago with light hiking platforms. (Before carbon fiber) How to do that these days? Not really hard....but mahogany planks, please please--- not.
  9. Experiences with G-flex

    This is exactly what I was hoping for. How to use this nifty stuff! Thank you forever, my buds Jan and Meade. You guy started this.
  10. Krylon Fusion... on PVC dinghey

    New Port Richie, FL? Give me a shout this winter and I will come down from Gainesville to see this proa. Or- Which part of Tampa Bay? I have 3 potentially useful hulls for such a project. One Prindle 19 hull, 2 Hobie 18. PS: Mahogany planks appear heavy, weight being the enemy of cats and proas. website--- catcobbler.com
  11. Experiences with G-flex

    How have purchasers expanded use of G-flex to fix modern "plastic" stuff? This is the 21 century, yet very few people even know the difference between polyester resin and epoxy. You ain't gonna learn this at school. How about on this forum. Here is the challenge! I want to see if other repair guys get the same result with G-flex as I did with ABS at least. I have a salvaged ABS paddleboat with age cracks. I treated the surface as per instructions (clean, sand, flame), smeared my new expensive G-flex on the cleaned up crack, put on 3 oversize 3 fiberglass patches, dabbing on the thick G-flex, then smoothed over with a layer of epoxy-filler in conventional West 105 + hardener. Result: Very nice repair. I wanted to see if the 2 epoxies were compatible, as West105 is WAY cheaper to finish the job. Remember that overhead film or any kind of Mylar does not stick, in fact gives a glass smooth surface.
  12. Krylon Fusion... on PVC dinghey

    OK- got it. You didn't try G-flex yet. I want to see if other repair guys get the same result as I did with ABS at least. I smeared G-flex on the cleaned up crack, put on 3 oversize 3 fiberglass patches, dabbing the thick G-flex on it then smoothed over with epoxy-filler in conventional West 6061 + hardener. Very nice repair. I wanted to see if the 2 epoxies were compatible, as 6061 is WAY cheaper to finish the job. Remember that overhead film or any kind of Mylar does not stick, in fact gives a glass smooth surface.
  13. Krylon Fusion... on PVC dinghey

    Has anyone tried G-flex on PVC dinghies? Or ABS or anything? I fixed age cracks in my pedalboat...results were pretty good.
  14. I've lost my balls

    Bird shot for waterbirds is now coated steel. BB-size is what I have seen in shotgun shells. Better than disintegrating plastic. Why not make your own track ends from epoxy with shredded filler-- West has lot of types of filler...these are really tough and can be machined. Gotta be better than melting aluminum for many $$$.
  15. Outrigger Fix May Be Useful

    The port hull looks more Hobie20-like to me. So this rig is depending on the H16 hull as an ama. Hmmm. Please tell us how this all works at sea. I have been present when the front end of a Hobie 18 Magnum comes off outside of the surf line... Saved them all!!
