Proboat 47' MLB rebuild

Thanks Greg. She's coming along!...

Like a good story- hard to put down sometimes.

After a few more coats of black - and days drying- and wet sanding...
She's ready for the white bottom.

Seems not all the paint was fully dry. I had a feeling I should have squeezed at least one more day of drying time seeing its been pretty cold.

Well, I had to wet sand anyway. Just didn't want to do it so soon.

The idea is to retain the silver undertones, and use the stainless color as the "dirty aluminum" look. (you'll just have to wait and see the grand master plan for the paint). 

Wet sanding the ... Ah humm, mistake:

LoL- she looks like she's had a brush with a coral reef!

Prepping for more color and coats:

In the mean time. A few accessory details in progress. Here, I'm making the three aft storage doors.

Using the plastic packaging from my epoxy resin - this gave the perfect curve for the interior of the hatch. The handle will eventually be made and fit inside. I'll have to cut some holes in the rear of the boat to fit these in so they will have to be water tight. 

I also made the escape hatch.

A little sanding and slap on some paint and it'll look just like a door.

Repairs to the rebuild repairs

Repainted the hull. "a-gain" Got a nice smooth match. Layering paint is great. Very strong! As long as you let it dry thoroughly between coats... (Doh!). Otherwise you pull off 6 or 7 layers by accident and create a huge divot! Anyway. This is me being very careful not to expose another 7 layers of under coat, and final coat of the black. I think this totals around 7 layers as well (?). I lost count of the black. Flat black goes on quickly and covers nicely. I'll later have a final wet sand on these coats (black and stainless) before hitting it with clear.

And yes, that's electrical tape. I like using it over masking tape. Makes SUPER defined straight lines without the paint bleeding under like masking tape does. You just have to be certain the paint is dry before applying. I prefer the 3-4 day method but I've been know to use a hair dryer before to quick cure it. ...As in this case. ...It just takes long (about hour between coats) to gently warm the hull with the dryer and dry the paint. I allow the hull to reach room temp too before the next coat goes on. And I coat very lightly and wet sand between coats. 


Now it's taping it back up again (yaye!  . ) to add the white bottom.

Hey, my pooch has those same markings:

I like working with gloss white but hate gloss in any other color. White always goes on like silk and never orange peels like black or red or blue in gloss.

Now, carefully remove the tape!!

The tape peeled away nicely without any problems this time.

I'll be doing more with the hull later.

Now, I'm off to build this red portable sump pump.

47' MLB sump pump

Banged out the portable sump pump in an afternoon.

For this part of the rebuild I'll need to cut into the aft storage box. A little nervous but I'm hopeful it will work out ok. I guess'timated the area from looking at many pictures (most stock photos of the MLB don't show this area well) and started cutting. The picture above in the prior post was taken from a news crew video.

After THE HOLE was cut into it, I used a 3/4" wide flat file to square up the lines.  I found the floor of the MLB slants downward slightly. By just looking at it, it appears as level as the top of the storage locker. This will make the insert I plan to install slightly difficult as I plan on a zero tolerance fit to make sure this area is water tight.

I looked at a lot of possibilities to make the sump pump out of but ended up using this red dowel from my 41' Dumas USCG kit. 

I plan on cutting it in half so it doesn't fit in the hole too deep and of course shorten it as its too tall.

Here's the dowel cut in half. I used a file and shortened the ends so it would fit in the hole better, and allowing space for a frame. It won't be noticeable later.

And then constructed a frame. I built the frame inside the hull first, then filed down any needed places on the dowel second so the dowel would fit snug in the frame (top to bottom) and the frame fit snug in the hull section.

I made the bottom fit under the can a bit differently so I'd know which side is UP seeing the hole is not exactly square.

I left a little air-gap in the sides so it looks more "lose" in the frame.

The air gap was later covered with epoxy resin to make it water tight but still appear as if it's loose.

Now it's just a matter of fitting the square peg in the round hole.

And now you have a portable sump pump.

I'll detail the pump with a lid and canister straps as soon as I figure out what to use.

just go surfing in the bay and "get stuck." A Motor Lifeboat is bound to come around and pick you up and bring you back to shore.

Hahaha.. That's funny Kev. Although I'm just not quite ready to fight the sharks off while the MLB arrives.

Got another update for ya.

Adding a "little" more black. The line just was a hair off on thickness.

That looks better.

Time to work on the logo


The white area I accounted for the logo was 1/8 inch too big. Only because when I removed the original logo, I didn't account for the small overlap of clear on the original decal.

Arse back to the sanding stone!

Other works... The rear doors prototype now.

The new doors will look much better now. The prototype looked good.

Construction of the aft bay doors

Doors are progressing nicely.

MLB doors

LOL - make more!?! Oh God no! Maybe in my "spare" time (LOL).

Testing picture posts ways. Photobucket only allows so many posting options.

Ok. So that didn't work. How are you guys posting pics?

I'm using the [IMG] method.

Scroll down to add captions.

Then, click close window when youre finished.

Just for telling you, you need to make me 3 sets of those hatches.

Flash player


Ah, the "paper clip" - unfortunately, apple doesnt allow the upload of flash player to iPhone or iPad (where I send my pix from). It'll take a little longer to post pics because ill have to transfer a different way and use my desktop but I'll start posting that way. I hate the long page loading time too.

I just got a new PRB3500 today, next to impossible to find but after a lot of research I managed to find one in Canada thats been on a shelf for 3 years the store owner said. I'm going to paint it CCG colors, what type paint should I be looking for? I already have some decals for 'Cape Naden' from on the way. I guess now starts the research process on how all that is done and what the proper procedure and things like what paint to use starts.
