Day 80, 3/4 Galley countertop templating, and removing old one. backstay chainplate replacement 8 hours

 Interior

Galley countertop and cabinets

Original countertop consist of two parts, One with sink and food storage locker lid.  

Another one covers ice chest and forms first step of companionway stairs.

I have made paper template for whole countertop.

I added check dimensions to be able to confirm if template is not deformed when i will lay it on new material.

Countertop is removed


Back side...

 

Left side is rotted significantly. At any case i am going to replace it.


Structural.

Back-stay chainplate replacement.

 Old chainplate was done from unknown SS bar, and manufactured very poorly. Pin hole was off center and shifted to the edge. thickness is 3/16"


So, I am going up size to 1/4" SS 316 . also installing old plate as backer. Hope it will make some difference to better side. Only thing leave me doubts is fact the plate mounted on transom with 4 x 5/16 countersink bolts (mean screw with hut). 

When I started to prepare to work I found the difference in transom thickens (~1/8") between two top and two bottom screws. So backer plate can't be mounted without of leveling of the area. 

I have grinned out gelcoat and laminated 3 layers of 1708 on the lower area with slight shifts to make area flat, then overplayed all area sheet covering whole area. also filled old (oversized) holes with thickened epoxy with silica filler.




Place cleaned.

Area laminated to level back surface to be able to use backer plate.

Red color is from pretty long stored fast hardener, west systems in theirs white papers do not conciser this as an issue.

Information from West Systems.

"Exposure to metal may cause the 205 Fast Hardener to turn deep red or purple. The metal from certain large capacity dispensing pumps may accelerate this condition, and exposure to the metal of the hardener container may also cause this change. The hardener’s color will not affect the epoxy’s cured physical properties."

When all epoxy set, I drilled new holes and installed new chain plate using new bolts.

<< Pictures will be made to add here>>>

Day 183 1/5/25 Take engine home.

Engine Take engine from the boat and move to home garage. Easy to say, hard to do. Water level in the lake now is 40ft below normal level. And total height drop between parking lot and docks about 70-80ft.  Marina has no lift, ramp or crane to move something more than 200 lb up way. Only way is very long stairs with 140 steps.   View form the parking lot...    Staircase we climbed up. Yes, you can see the lift, but it is only 200lb capacity and no way to use. Picture was made on the middle of the process. Based on engine spec it has to weight 400 lb. It is a lot but should be more or less bearable weight for 3-4 people. Challenge was accepted, but looks like it is heavy enough to do a problem ;-) Moving from boat to dock was very easy, just hook chain hoist to boom lift it  and swing boom to the dock. put on a dolly and roll it to staircase. After an hour of planning we (My son and I) decided to use blocks and ropes to slide it up. We mounted engine on the plywo...

Day 138, 4/6, Deck priming, 2 days, 8 hours total

 Deck Spent a day to wipe all to clean, then de-greaser, then solvent, and then priming.  Surface area is not too big, but still be ~400 sq.ft.    I did wiping and cabin top at one day, cockpit and area next to toe rails in second one. Primed only area plan to paint glossy. non-skid paint does not require priming, just washing with detergent, but it will be later.  Observed two problems  first - rolling and tipping leaving brush marks  even when 25% solvent added. Second - (actually helps to maintain first) I need second layer because  one layer of primekote does not covering well. So, I plan one more gallon of primer and one mode day to of sanding and one more day of priming.   End of day1     End of day 2
