Duration for Screws in Aluminium mast?

Postby richy-c » Tue Mar 26, 2019 7:00 pm

If used with white grease how long is it advisable to leave stainless bolts in Ali mast before removing?

I would say 1 year in fresh water, but no longer than 1 month in salt water if you were generous with the grease.

Use Tef-Gel for anti corrosion and anti seize, that stuff is da bomb!

Two weeks tops, in normal salt water, to avoid getting stuck, even if soiled in tefgel or similar.

My maintenance interval is half a year, and I ride in salt water. First, if you generously cover threads with gel (or any other grease, for that matter), then there is simply no way for the water to infiltrate the threads. For extra protection, you can seal the top of the threads with pipe thread sealant/cement -- just make sure it doesn't go too deep. (Otherwise, when solidified excessive thread sealant would require some torque to unscrew the screw).

I have experienced screw seizure (well, almost) the very first time, when I thought that spray foam would be a good water repellent. Still, splashed some hot water over the mast (I didn't have heat gun at the time), and with some effort the stuck screw did come out. Using grease and thread sealant ever since, and no problem whatsoever.

But the lowest common denominator must be the answer, right?

Some can avoid screws getting stuck for a long time yes, but if anyone having used tefgel and similar, experience they get stuck (I did, 3 weeks, but was lucky to get them free with special tools), it must be the answer if you want to be "safe".

Somewhat like mildew - some never experience this even with wet kites, others get brown kites after just ONE single night when the kite is left wet overnight :o

I dont know if anyone rinse their gear after riding, I dont (and wont, when riding +200 sessions a year)

So disassembling now and then and more tefgel is the key IMO.

If you generously apply Tefgel, you can leave if assembled for months, if not years.
That's my experience. I've only taken the wings off the fuselage 2 or 3 times in over two years.
Each time I did, I reapplied a thick layer of tefgel. Never had a problem, and just verified that I still don't :)
As for the fuselage to the mast, I have to disassemble anyway to fit it in the car, so I take it off after every session.
I did have some tefgel on these bolts too, but I found that by repeatedly screwing the bolts in and removing them, the tefgel soon came off anyway, so in the end I stopped bothering.
So you kind of got to go one way or the other.
I got an Zeeko mast, it came factory fitted with the base plate bolted to the fuselage with tefgel coated stainless bolts, with the recommendation never to disassemble it.
So they must have have had some confidence that it wouldn't be a problem.

Personal experience is that fresh water environments make it pretty feasible to own an aluminum set up. Heading into my fourth year with the same frame and I disassemble for winter and give it a good coating of tef gel in the spring. The first year I was all over taking it apart every couple of weeks. The second year mmmm maybe every couple of months. Last year, I took it apart completely once mid season, and I'll likely do the same once this next summer. I take my fuse off the mast and the mast off the board every session, but the wings stay on the fuse, and the plate stays on the mast. Have had no corrosion at all so far.

Im sure it would be different in a salt water environment.

this is interesting discussion as this is definitely one factor considering carbon vs aluminium ...for example i'm considering NP Glide surf foil vs Moses Onda and the price difference $1000, weight 1kg? ...so if Alu only disassemble every 2 months perhaps Alu…
for me foils are pain as it is do not want to add another level of maintenance item...life is short :)
