Maintaining Bolt Torque

[Old Yeller]

Frustrated... still waiting on a resolution with the MI. It’s been 4.5 months (135 days) now. This isn’t Rocket Science, it’s obsolescence that needs to be corrected by preventative maintenance with a needed design change.

FYI: If you have this design of Rib-Gunnel attachment, pull the walk boards and inspect them; If they are not parallel mating surfaces, have a gap below the bolt, attached with full thread SS bolts, and are not secured to the hull sides...


Regardless of how frequently you tighten them, the unveven mating surfaces will continue to frett to some degree

Another 3.5 months have passed . . . Still waiting on that CG835

It looks as if your already running a poly nut on there. Were the poly nuts new or did they already have use on them?

I find after use they won’t hold as well FYI.

Tricks we have used on difficult applications have been to use a commercial thread lock like LocTite. The Red #271 is a permanent thread lock compound. If it is the nut coming loose and not bolt stretch, the #271 product will stop it.

Another less intrusive trick is to put a smear of High Quality RTV sealer such as Permatex high heat on one side of the threads and tighten it down then allow 24 hours to cure. Make sure the bolt and nut are clean and dry. The objective is for the sealer to bond and created a filler in the threads and barrier to backing off. Put a little up under the nut after tightening also. Just a pea size amount and wipe the bolt and nut base.

I suspect part of the issue is that the nuts can’t torque flat as they are drilled in at an angle so any flex is working to mechanically loosen the nut. It they were flat the added surface tensions would hold better.

I agree totally with this cant say it better.

NUTS :banghead: are new Nylock. Just too many opportunities for movement for anything to ever stay tight.

Would someone running a CG Certified db 23' x 9'10" Tour please send me the vessel name & official number so that I can get the approved plans to verify dimensions?

 

[Old Yeller]

In addition to the request above:
Would someone with a 2016 or older 9'10" x 23' Inspected (COI), that utilizes similar construction (5/16" bolts, etc...), PLEASE give up the official number/name? Or tell me who has one so that I can go get it...
It may be possible to apply the five year rule to some of these issues.
11 months into this re-inspection process now! :banghead:

Hi, I am beginner, what's that in bule color? Is thar something anti-corrosion?

 

[Old Yeller]

Nope, just paint to break things up and cover up more crater cracked welds . . .
Based on ANOTHER Inspection yesterday in our continued quest for a resolution with USCG. Interesting this inspection was the one year anniversary that we started this mission on. How many years can this process take?

Is anyone going to step up and PLEASE give us a boat to sistership to?

 

[Old Yeller]

TTT

DB Cooper . . .

. . . May be more elusive than a set of CG approved plans for this boat!

:banghead:

 

[Old Yeller]

... after more than a year the Official "Work List" has arrived.
#1 remains the plans; #3 & 5 address multiple cracked welds. Many are crater cracks, so we get to clean all, inspect, repair all cracked ...
The bottom splice gets a 4" clean path for the entire 23' run. Gonna be a bitch to clear Super Slick w/o damaging the weld!

 

[Old Yeller]

Strongly suggest you review the record for your SPV and notify the OCMI of any discrepancy!

Is "An affirmative defense to a civil lawsuit... a fact or set of facts other than those alleged by the plaintiff..." ?

Does anyone else want to hear how "Any loss, injury or damage suffered by Plaintiff was caused solely by the acts or omissions
of third-party parties, including but not limited to, the U.S. Coast Guard." on this build ?

(d) The OCMI may require an inspection and testing whenever a repair or alteration is undertaken.

>>> Given it was NOT "in kind", WTH is it? AND WTH are the plans for this master piece?
4.5 yrs now :scratch: Come on . . .

 

[Slidin Gator]

Yah, that’s the kind of stuff that calls for a naval architect. He will just determine that the boat is unstable (duhh).

Your money would be best spent on a CG approved hull.

 

[Gary S]

Has this boat been out of service this whole time? And where are you located?

 

[Old Yeller]

Slidin Gator, "Your money would be best spent on a CG approved hull" That's what I bought! It is (was) until this CG835 was issued for the approved plans.

Gary S, It's been officially out of service since 31MAR2017, it "worked" one day! We've been trying to resurrect it all this time. It's up in AR, working with Sector Lower MS

Considering this is a current production, certified 2021 SPV:

What is wrong with the interior framing assembly shown?

 

[Old Yeller]

Anyone know if this remains the current approved drawing for the gusset assembly in the previous pics?
Anyone have any 3/8" bolts in the framing?
