If it's fine enough to sneak past everything you throw at it, a wrap or two of tape should do the trick.


Actually, I don't have a problem (anymore), since I began using the silicon tubing, on all six joints. I must be using that soft "gummy" stuff, that Pete referred to. Either way, it is very pliable, and it seals up the crack completely, between the end of the cap, and whatever tube I'm using. I just don't get "any" sand, in the end caps, now.

As I mentioned previously:
"I fly predominately on sand, and the surgical tubing has worked flawlessly, ever since I started using it. Also, I use the tubing at all six (6) junctions - both ends of the leading edge, and both the top and bottom, of both verticals. Yes, the upper verticals already have factory supplied dust covers, but fine sand can still get in, especially with 2-wraps & race rods. Again, I've never had a grain of sand, to get into any joint, using the surgical tubing (silicon tubing with a 3/8" OD x 3/16" ID, cut into 1/4" lengths), and now I have it on each end, of each frame section, that goes into an end-cap, and I see no reason to remove it."

I know it's hard to believe, but you just can't imagine, how fine the sand on these dunes has become, over the years. The sand on the beaches, is generally, much coarser, and not as much of a problem, so normal precautions work fine there. Posted Image

Nick,

I now understand that you are doing basically the same thing with the silicone tubing as the o-ring approach - sliding it onto the rod to act as a plug to seal the gap in the cap. I have been using 3/4 to 1/2" lengths stretched over the end of the caps while still closing on the rods. Someone on this forum made this suggestion and it has worked for me, but the rod is sometimes gripped by the sleeve and requires a slight extra effort to hold the cap while pulling out the rod. Your approach seems like it might have advantages - half the weight, option of using it on the top inner joints under the pvc sleeves if needed, and no friction to resist removing the rod. I also suspect placement would be more secure with silicone tubing than o-rings which could slide, since it is of no value if the material doesn't contact the cap to seal all around.

I will plan on trying your variation on my next beach flying trip. Thanks for the suggestion.

I don't know if this topic has gone somewhere else but it looks as though the sand problem is still there for some.

 

Instead of caps, "O" rings, or tubing, why can't each end of all rods be filled with a squirt of silicon glue and solve the problem once-and-for-all.

The weight of a lump of glue inside the tube will be no more than a cap or something. Do the tubes have to be open or I missing the point.

It will keep the sand out.

Reason - wrong problem!! Our various solutions weren't about getting sand in the ends of the rods, but between cap and rod!! The "O" rings and tubing fixes were to keep the sand from getting in the cap and making it very difficult to pull out the rod!! The fixes are different based on what kind of sand you're trying to keep out!!

Now if only I can figure out a way to deal with the humidity + powder like sand on some of our beaches which result in the entire sail and lines being coated in a layer of the stuff ...

:(

Sorry being a "New" guy with bright ideas,I should just find that sand and stick my head in it.

Well, you know when you get in the shower in the evening (well, maybe we shouldn't go there), but just a suggestion..........or maybe a water hose, for the Rev. 

 

When I fly on the dunes, during the hot days of summer, many times I come in and step in the outdoor shower for a quick rinse off.  Then I grab the Rev, hit it good on both sides with the water hose, and we both go up and sit on the deck, in the sun & breeze to dry off.  Hey, it works for me, but probably not so good in cold weather............ani_whistling.gif

Hey - no harm, no foul!! Several of us have tried many times to combat the sand issue, and these are the fixes we came up with!! Some use them, others just use force, but at least we gave it some thought and tried something!! You had an idea, no problem here!! But I'd hate to try to use that rod in the leading edge after you filled those ends with goo!
