    Floor replacement question

    Re: Floor replacement question Here is a picture of the completed stringers next to each other: The next step is to make a pair of bulkheads to replace these two which were on either end of the gas tank: I have them laminated and cut to width, but need to cut out the exact shape. I am...

    Floor replacement question

    Re: Floor replacement question It's been a while since I posted because I haven't had much time to work on the boat. Camping with the family and soccer tournaments (finally over!) occupied most of my time. I did have some time to work on the boat and here's the results: The original...

    Floor replacement question

    Re: Floor replacement question Tonight I finished most of the grinding for the stringers. After grinding in very hot temperatures, working at a temperature of 73 degrees outside was almost relaxing. I still have a few small spots to touch up with a smaller wheel, but I finished the big stuff...

    Floor replacement question

    Re: Floor replacement question I started the grinding today. My question is how much of the old tabbing do I grind away? Should I grind until the area of new tabbing (6" on each side of the stringer) is at the same level as the bottom of the "slot" where the old stringer was? Here is a...

    Floor replacement question

    Re: Floor replacement question Since I had chosen not to remove the cap, I was going to splice the stringers just under the front bow section. On the left side stringer, there was a large cutout for the fuel filler hose near the area where I was going to splice. I did not feel a splice here...

    Floor replacement question

    Re: Floor replacement question I have now removed both stringers. First I cut through the stringer close to the hull with a sawzall: Then I used a 3/4" wood chisel to remove the remaining wood in the slot, usually about 1/4" to 1/2" high. The factory used foam to fill in any...

    Floor replacement question

    Re: Floor replacement question OK, more progress! Here's a picture of the transom core installed on the boat with the clamps, outside view and then inside view: It came out pretty good but not perfect. If I was doing it again I would have put more PB around the edges so it could ooze...

    Floor replacement question

    Re: Floor replacement question I'll try the 36 grit disks from HF when I run out of the 24 grit I already bought. Also, thanks for the de-gumming tip to clean the discs. I noticed that some forum members recommend using CSM between layers of 1708. The 1708 already has a layer of CSM attached...

    Floor replacement question

    Re: Floor replacement question Thanks, 93bay. That's what I did to my transom also. Here is a picture of the transom core ready for resin: Yes, i know that the top of the cutout is slanted, but that is how the outer skin is cut out. I removed the outdrive and engine a long time ago and...

    Floor replacement question

    Re: Floor replacement question Today I cut out the outdrive hole in the transom core. The two layers are tightly glued together and look like one piece of plywood. The Titebond III did its job well. Here is a picture of the edge of the part that was cut out: Then I did a dry test fit on...

    Floor replacement question

    Re: Floor replacement question This morning I glued up the two 1/2" arauco ply transom pieces with Titebond III: A few days ago I glued the two pieces together for the small outdrive area section of the transom (Is there a special name for this piece?). If you recall from previous posts...

    Floor replacement question

    Re: Floor replacement question Well, I sanded the transom outer skin today. I used a tyvek suit with a respirator and glasses-type goggles. After sanding a little, I noticed that some dust was still getting in my eyes, so I added a face shield on top of everything and that seemed to work well...

    Floor replacement question

    Re: Floor replacement question Thanks for the replies. I am going to use PB to attach the new core to the skin. I removed the old core yesterday. The rotted and weakened parts of the core came off pretty easily. The good sections ( about 2/3 of it) were another story. After trying several...

    Floor replacement question

    Re: Floor replacement question The series of events that kept me from working on the boat continued this week as work sent me on a trip to the west coast for 3 days. Finally, yesterday I was able to work on the transom core (after an overnight redeye flight across the country). Here is a...

    Floor replacement question

    Re: Floor replacement question Well, I'm finally hoping to get back on the boat. The last week has produced a series of appliance failures at home that I had to fix, along with a large tree that fell across my fence that I had to cut up. I made a rolling dolly for the engine using four HF $4...

    Floor replacement question

    Re: Floor replacement question Here are two pictures of the boat on the trailer: The trailer has rollers that the boat sits on. Should I add some extra supports for removal of the stringers? Steve

    Sanding Down Fiberglass

    I have a couple of Harbor Freight 4 1/2" Grinders. I use the metal cutoff wheel to cut through the tabbing to free the stringers, etc. What sanding wheel do you use to sand down the existing fiberglass to a fresh layer? I have searched the posts but only find reference to sanding down to a...

    Transom Thickness Problem

    I am in the process of replacing the wood core in the transom (1984 Larson 19'). After removing the engine and outdrive, I took measurements of the transom thickness at the outdrive cutout. The Mercury outdrive manual says the minimum thickness is 2" and maximum thickness is 2 1/4". It also...
