Re: [Amel Yacht Owners] Rebedding original handrails


James Alton
 

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,
  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.  Dependin g 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.
