[Amel Yacht Owners] Rebedding original handrails
|
David Vogel <dbv_au@...>
Hi James, I've heard that attending to this should not be ignored, and that
thereafter regular maintenance every ? years to re-bed the railings
to minimise the chances for moisture ingress. Like the bow-thruster or windlass, if not attended to, then it can be really hard to make right. But with pre-emptive maintenance, things go easier. The reason is that the rails are
affixed internally to an iron sub-structure, and if moisture gets in,
then the results are inevitable. Best, David Vogel Moonshot, SM#396, Rhode Island On Sunday, 9 October 2016, 3:47, "lokiyawl2@...

David,
I agree with the preemptive approach. With the handrails I am unclear on how they are fastened. Are there nuts under the headliner or???

Hello,
I was hoping that someone might know how the stainless tubing forming the handrails on the cabintops is fastened down? I have some rust in the area that the handrail sits on the fiberglass in a couple of places so I am concerned that moisture is being held in those areas. I do not have any obvious leakage below at all.

James,
I believe David is saying that the handrail bolts go into a steel (iron) threaded plate that is embedded in the fiberglass deck. No bolts are involved. Amel used this technique in many ares, like the engine room hatch cover hinges and pneumatic piston mounts, the bases of many of the stancions, etc. The problem is that if there is water ingress, the rust you see may be from the embedded iron starting to deteriorate and "bloom". That will eventually cause the fiberglass to expand with the surface bulging out or even opening up - I recall Bebe Bill and others had this issue with the engine room hatch cover at the piston mounts. I had it with a stern stancion actually cracking the cap rail structure open; So, preventive/corrective maintenance would be to remove the bolts, passivate the rusting internal plate, and "permanently" seal the bolts on reinstallation. Depending on the degree of deterioration of the backing plate you may want to remove and replace it, although you'll have a challenging fiberglass repair job. Alternatively, one can drill out the rusted plate a good distance around the bolt hole, fill will epoxy (like JB Weld) and retap the threads. Having said that, you may just have some minor surface rust coming from the stainless hand rail base, that is of little concern and easily cleaned up. Cheer, Craig, SN68 Sangaris |

James, I wrote my reply before looking at my own cabin top hand rails and assumed they were fastened with bolts from the top like the stancion bases. Actually, mine have no bolts going in from the top and must be bolted from the bottom through the aft cabin overhead and then covered over with the vinyl headling, although I could not feel any bolt heads through the padding. Hmmm. Pehaps the SM is different than the SN. I do have some very minor rust stains around the bases - must have the Admiral get on that.

Craig,
Thanks for your response. There are not any obvious fasteners anywhere on the handrail to remove so my problem is determining how it is fastened. There is not any bulging of the fiberglass or any large amount of rust. I removed the plastic plug at the end of one handrail and sighted the inside of the tube with a strong flashlight. It appears that a stud may be welded to the bottom of the handrail but I cannot be sure. If so then perhaps there are nuts under the liner but I cannot feel any. I hate to start cutting up the liner to investigate so I was hoping that someone knew how the handrails were fastened.
Best,
James

James,
on my Mango #62 (built in 1986) the handrail bolts have nuts hidden behind the headliner. Alan Spence s/v Charisma, Mango #62 |

Alan, Many thanks for the input. Our boats are only a year apart in vintage so it would seem likely that this could be the same. Since I posted my question I found that the nuts for the mizzen traveller are set in flush in the overhead under the liner which probably explains why I cannot feel the handrail nuts.
