1995 Grumman 1784 TC Complete Rebuild

Post by dearl » 02 May 2016, 08:46

Some shots of the finished rivets on the first stringers we removed, checked for corrosion and replaced. All the rivets were sealed with 5200 and drove home with a rivet gun. We're going to remove all the stringers and strakes and do this for all of them. Got the next 2 stringers up and found some real nasty corrosion, had already eat a hole through the boat. I'll acid wash this to kill the corrosion and wire brush the crap out of it, then fill in the void with JB and sand smooth. Feels good to be putting her back together.

Not much to report, finished welding all the holes up in the splash well, still working on corrosion control. The transom skin, and the last 1/3 of the boat was the worst. I used diluted Muriatic acid, a stiff stainless brush, and baking soda dissolved in water as a neutralizer. Worked small areas no more than 3 minutes each then washed the area real good. Works great, already started to JB some of the really bad pits. Hoping to get the rest this week then its on to Gluvit and primer.

Got a little done on the boat yesterday. Broke down the splash well for sanding/primering/painting. Sanded the JB spots on the bottom under the stringers. Replaced some rivets on the Nose Bulkhead, installed 2 stringers, Plan to get 2 more installed today, and hopefully remove the next 4 for inspection/repair. I did sand and primer the forward bow area that will be painted, amazing what scratches and dents show up after primer.

Still working on stringers, got the first 4 installed, zinc chromate primer on the stringers and floor area under the stringers, then re-installed with 3/16 x 1/2" brazier heads dipped in 5200. Had to weld up and re-drill a few holes due to being over sized. Next 4 stringers are up, not much corrosion under these but 2 of the stringers came out in pieces, planning to get those fixed today, cleaning up the floor area, knocking out the dents, primer and re-installed by the weekend. Then its on to the last 4. Drilling out rivets is no fun.

Moving right along...Got all the corrosion removed and pits filled under stringers 5-8, Got the transom pits filled, also got the splash well sealed and reassembled. Still need to fair the splash well out a little from the welding, then its getting ZC primed. Going to spend this week re-installing these stringers, pulling the last 4 stringers, repeating the corrosion removal process, Re-install those, and get the unneeded transom skin holes welded, then install the new transom wood. I want to have the boat flipped by the end of the month prepping the bottom for paint.

Transom skin pitting built up with JB and sanded smooth and primed. I'm really happy with the way the transom skin turned out. looking forward to getting the wood core installed.

Thanks for the compliment....spend a lot of time working on aluminum boats, also gained a lot of knowledge over the years from this site as well as others.

Just about done with the corrosion removal and stringer replacement, I can FINALLY see some daylight with this part of the build. Got a lot of material in this weekend. The epoxy/cabosil is in along with 8 yds. of 6 oz. glass for the transom. My 4x8 sheet of .063 aluminum plate is in for the splash well back plate, and nose cap. We fixing to kick this build into high gear.

Haven't done a lot to the boat past week or so, Had 4 boats come In the shop back to back and its been miserable Hot past couple of days. Well last night I finished cleaning and primering the last 4 stringers, sanded down the JB filled pits and primed the bottom. Tonight we plan to install these and hopefully get the bow supports ready to install. I've gotten everything ready to lay up the transom and bow plate, just need to get after it.

I had planned to use the old gunnels, even welded all the holes up and sanded them down, but they warped on me so, I'll use the old as a template and cut new ones out of .063. No sense in cutting corners now, we still got a long way to go.

Maybe I shouldn't have said we fixing to kick this build into high gear, more along the lines of we fixing to throw an anchor out on this build! No worries, she's been put aside for the winter to get some work done, between boat jobs I've been getting material together to get started on her again soon. Looking forward to working on my own stuff LOL!

Well after many, many set backs I have officially begun the rebuild of my V-Hull.....again! I've stopped taking in large jobs In the shop for a while so I can get my house ready to sell. I figured since the shop was empty and I just finished my Jet boat I will need something to tinker with at night....So I brought the ole girl up to the shop, give her a quick pressure washing and backed her in the operating room Lol. It will be slow going so don't expect the mods to come quick like my jet boat, like I said I'm trying to finish the re-modals on my house so everything will be done at night, slow but steady wins the race right. First order of business is to finish up the stringer install's, still have several left to do.

She looks as good as she did when I put her up almost a year ago.....
