rub rails and body work
« on: September 20, 2018, 07:44:33 PM »
So.... I took a little break from the V 179 to do harvest and canning from the garden but now I'm back at it. I have been doing research on if I should put the rub rail back on before doing my body work on the cap or leave the cap loose but sitting on the hull. I plan on using a dremmel and opening up the cracks and then filling them. I have noticed that my hull bends in just a bit and have been thinking maybe I should secure it before working on the spider cracks-I should say I have more than a few spider crack areas because of the stress that was on the top before. The info I have found is split-what do you guys think and here are some pictures

Every Glastron I've split had a ring of screws securing the halves together, then a separate ring of screws for the rub rail.  Since the rub rail holes line up, I'd seal and attach the top with countersunk stainless screws between the existing holes.  Do all your body work and paint then since you have taken out a lot of flex.  Masking and painting is much easier without the rubrail. Then you can polish and clean the rub rail before reinstalling.  I used camper seal on the split last two resto, but some used 5200 or other marine adhesive sealant.

so counter sink them so as to leave them in? ( I like that idea ) Mine had pop rivets to the inside to secure the inside wood rail and then screws to the railing. I ended up gluing in the wood backing. I think I will pull out the aluminum rails and match them up to the holes to see where they fall.

Consider replacing the wood inside if it is suspect of not holding screws tight.  Otherwise, fill the holes with some type of filler, I've had good luck with pl-375, but there are plenty of options.  This insures the screws tighten properly.   Yes, the countersunk screws stay in place, the rub rail then covers them.  Rivets can work, but I think #12-14 SS wood screws work better than rivets.

sounds like a plan. I already did replace the wood  and fill the holes and I do want to use screws instead of the rivets-except for 4 holes in the very back by the transom.I'm thinking I should add some pressure on the inside to ensure good contact with the hull and cap or will it all just pull in as I go around. Do you go one hole to the next or stager it like tire nuts going across from each other? seems like this part could be more critical than I thought? or am I over thinking this.

When I mate a top back to the hull it seems I have to go around multiple times to get it all tucked back in correctly.  Looks like you supported the sides, which is good.  I begin at the transom with a few screws loosely holding the alignment in the rear, then massage the bow and sides back in place, again adding a few screws loosely to hold alignment.   Add screws to the rest untill the alignment is correct, and either the seal or sealant is in place.  Now you could complete the process going around, or alternate sides, I doubt it's that critical at this point.  I've found the bottom hull to relax and it does take some effort to get it back together.  I found construction door shims really helped.

good tips-- the deed is done and its slightly off but I think its O.K. I did notice earlier that one side of my windshield was higher than the other when I was tearing it down and I think that's why one side is off a bit. I'm getting on the spider cracks now, fortunately nothing is too deep. I did burn up a dremmel today but got the extended warranty knowing what fiberglass can do

weather has slowed me down but I'm on my third coat of body filler--seems it takes longer to dry ( by a few more days ) even when I almost double the catalyst because of the cold weather--should hit 69 today though and hopefully this will be the last sanding. I think I will switch to planning the interior and making purchases over the winter and possibly starting on the engine rebuild

Looks like fair progress, but your right, time to start prepping for winter and working on the interior and engine in the warmer areas of the house.

We hit 70 degrees today with full sun- so I couldn't resist and rolled out the boat and put one more layer of filler on-its really thin so I think it will set up easy and sand easy. After this if I get a chance ( probably not ) and feel the need I will just use sandable primer. The weather forecast says snow Monday or Tuesday.
