Day 51, 10/8, Stanchions re-install, wind instrument holder complete. 8 hours

 Stanchions How it should be made  Picture from Irwin site. Construction problems:  Stanchions are empty pipes - and water can easy get in it Water is running down to wood block. Woodblock has no drain, so water collects there and problem is not visible until it rotted completely. Pipe is welded to flange but tot as continues line and has some gaps as well. Flange mounted with short food screws  to the deck.   What was found:    During manufacturing workers messed the design and drilled holes in about 1" farther from hull edge, as result pipes did not went to the wood blocks and appeared "in the air". To hide this they added nice laminate but did not fill it and just sick some not even soaked fiber cloth. Also this mistake resulted  the sealant has to be filled in cavity bout 1/4 inch  between flange and deck, it was also point leading to failure. Previous owner tried to screw stanchions to toe rail adding some bracket , but it did not hel...

Day 22-23, 4/22 - 4/23/22 Stanchions, companionway slides, port chainplates 12 hours

Companionway slides Did dry fit  and temporary installation on slides. Cut front edges at proper angle. need to recover with teak oil.  Looks cool. Mount holes drilled from inside, then metal inserts for M6 bolts installed in wood to screw rails from INSIDE and eliminate additional holes. Next time will install with SS screws. Fixed  window Had to redo fixed window. I one place there was not enough sikaflex.  Learned lesson - put more than enough ;-) then clean excessive sealant.     Stanchions  Before, oak wooden blocks with drilled oversized holes was mounted from inside the hull. then i drilled out 1" diameter holes for stanchions under deck pipes. Drilled the way there only plasick will be in contact with   stanchions. I have marked exact places of screws holding stanchions and drilled out holes 10mm and refill with thickened epoxy. Plan for the future - drill them and put machine screw thread 1/4-20 for 2" screws. 1" holes are drilled...

Day 21, 4/16/22 Stanchions, 10 hours

Water is going lower and lower   Stanchions      Removed all old "empty" stanchion support boxes  All 5 what we did was empty, all old wood rotted out completely. Looks like somebody put thin layer of epoxy covering cracked gelcoat and de-laminated glass around screws under stanchions flanges before 3M 5200. Yes, it was 5200 sit pretty well on deck but absolutely no adhesion to stainless steel. All stanchion, are empty inside - means water which gets onto stanchion pipes went directly to wood. Good deal for maintenance cost in a future.    My dad helping me with this work. Prepared wood blocks to fill the place. Blocks before filling with structural putty. Other story... One of place looks like was repaired filling oversized holes with not-thickened epoxy, and sure do fall out. I dig out all cracks and filled cavity with structural putty. Next time will sand and fair surfaces.   Port side chainplates Eventually. Last 2 chainplates to replace...

Day 18-19, 4/9/22 Starboard deck fairing (cycle 3 and protective paint), Stanchions, Bulkhead tabbing, Fixed ports, 10 hours

Starboard deck  Finished deck fairing and painted with gelcoat for protection. Just  protection reason final fearing will be done during deck painting prep. <<TODO: Final picture to add>>> Chainplates  Drilled holes and put all new chainplate mount bolts  Starboard bulkhead Starboard bulkhead tabbed to hull on both sides of bulkhead . Used 2 layers of 1708 and 1 layer 24oz Woven Roving using Epoxy resin  Stanchions  Cut original mount out on starboard aft stanchion. No leftover wood found. Found a pretty strange stanchion flange shape. It has 3mm step on one side.  Looks like it was designed to overlay toe rail, but holes were drilled in the wrong place. I built new oak wood block drilled oversized hole for the stanchion pipe, infill it with a structural putty, than drill it back again to make plastic touch the metal only. then install it back to hull with the same structural putty following fiberglassing it to the hull side. 2 layers og...
