1972 Silverline Grand Bahama

Re: 1972 Silverline Grand Bahama

I finished tearing the old transom out. There is still a thin layer of ply on there but it should grind out easily. I didn't want to risk damaging the skin by trying to get it off. Even with all the ply out the transom hardly moves at all, the skin is really thick. I still need to check for straightness but it looks really good so far.

I still have a huge mess to clean up. The garbage man comes tomorrow so I better get back to work!!

Re: 1972 Silverline Grand Bahama

I got the hull all cleaned out again. I still need to pull the rest of the stringers and foam but that should go fairly quickly. I did pick up a bunch of stuff for the boat today. I got 9 sheets of 3/4 Auruco ply, 5 sheets of 1/2 Auruco ply, a few 2x4's so I can add some bunks and I ordered bolster brackets as well. Next week I will be installing the bunks for some added support.

I also picked up two more tyvek suits and another grinder (Dewalt). The Dewalt grinder I have now has outperformed any other grinders I have used so for a little more money I am hopefully saving some headache. It comes with a 3 year warranty so I should be covered there

I hope I have enough ply.

Re: 1973 Silverline Grand Bahama

Nice materials score...I think you should have just about enough ply to do a solid 99.9% of the Silverline on hand...I just don't know what you are going to use for that last .1%......maybe some Teak...or Mahogany...??????

I totally agree with a pair of twins hanging off the back...personally I like the I/O set-up for exactly the same reason you noted...gravity shift...and you also mentioned they being available and affordable...in my book that's a Win-Win-Win!!!

Transom tear out is looking very near completion...

Keep up the great progress!

Re: 1973 Silverline Grand Bahama

Actually GT, I have a BUNCH of teak the PO gave me with the boat. Some of it got stained with gear oil so I'm not sure if it will be any good. The rest of it will need finished. It is pretty much all 1.5" x 3". For all the woodwork inside the cabin I plan to use oak veneer ply since it will be out of the weather.

Re: 1973 Silverline Grand Bahama

In gunsmithing, there is a white powdery stuff called Whiting...it is Calcium Carbonate...it acts like a sponge to help leach out oils and whiten or lighten wooden stocks that have grown too dark with age or are saturated with oils...

There are a couple of different recipes that you can make, using a combination of one or more of the following: Acetone, Whiting, White Vinegar and Bleach...

You can search the Net for "Refinishing Gun Stocks" or "Cleaning and Lightening Wood"

Here is a link to one method

One of the methods I have used is the following...

For the first step...An Acetone soak for a day or two can help remove a lot of the gear oil...use a No.1 steel wool pad to scrub the wood after the first day...

The next step, you can use a propane torch and the Whiting powder...gently warm the wood with the torch and apply a paste made from the whiting...this will soften the oil down inside the wood and the whiting will absorb it much like a sponge...Do this several times, until you feel you have gotten the majority of oil out of the wood...

Then use a 25% bleach/75% Water soak for a day or two...You can also 'paint' some Bleach on the wood and let it sit in the Sun for a day, then flip and repeat...

After bleaching, use the white vinegar to help remove the bleach and stabilize the wood...

Let it dry thoroughly for a few days, and it should look like new, ready to stain and seal...if not, you can repeat any or all of the above...

Nice stack of plywood, did I hear you mention some stickers for under the ply? A nice pile of teak will dress the Bahama out nice! Esp after some quality time in GT's oil leaching solution!

Middle of Idaho you can find 2 kinds of Auraco, much of the rest of the US, sorry no Auraco available, fire yadda yadda yadda:facepalm:

Re: 1972 Silverline Grand Bahama

OK, I can at least help with the therapy since wife owns our private practice. I'm still trying to incorporate that into the name of our boat but everything I come up with would possibly offend her clients.

Good luck on the tri-hull. That thing is amazing. I'm getting ready to rip up the carpeted floor in our boat and put down ply and some textured gel coat. Maybe self bailing like my father-in-laws Grady White walk around. I'll be watching your build closely.

Re: 1972 Silverline Grand Bahama

GT, that is some good information, I will have to give that a try.

JB, iboats is a one stop shop for everything I did put some 2x4's under the stack of ply. I still need to put some weight on top to help flatten out the ones that were a little wavy.

Carbidetech, welcome to iboats and thanks for stopping by.

Re: 1972 Silverline Grand Bahama

Today my bolster brackets and u bolts came in for the trailer. There were 4 missing and some missing hardware from the box being damaged. I contacted the company I got them from off of ebay and he was going to ship out replacements today. I also got my bunks cut down to size and carpeted. This is going to be alot of work but it will give me reassurance in keeping the hull straight and true.

The new shoes for the admirals car came in today to. All I have to say is tires for an 18" wheel are expensive. Just need to take them in to get mounted up tomorrow.

Darnit ... my new truck has 17" wheels. I'm now more afraid than I was before. :facepalm:

My truck has 17" wheels as well. I replaced the tires two years ago to the tone of 1200 bucks. Then again I'm running 35" BFG Mud Terrains

Re: 1972 Silverline Grand Bahama

I got two bunks put on today. It was another hot day but laying in the shade of the boat helped I had to do a little work on the trailer as there had been some modifications made I had to modify. On the bottom of one of the crossmembers was a piece of flat steel I had to cut out. I'm hoping to have one more put on tomorrow and when I get my other four brackets in the mail I will get the last one put on. I still need to square up all the brackets.

Piece I had to notch out on the crossmember.

The first bunk I set in place. This thing is going to have a ton of support!!

... that monster probably weighs almost that much

Bunk looks good.

Re: 1972 Silverline Grand Bahama

I have been doing some research lately on boats with twin engines. It seems that most boats up to 25' will run 2 140hp 4 cylinders while boats 26' and bigger will run the 165hp inline 6's. I finally convinced myself that this isn't going to be a speedboat. I just like the cool factor of having two legs hanging off the back. I also have to consider weight in with this to.

With that in mind I picked up a donor for $100 today. It doesn't have an outdrive but everything else is there. It was a project that someone started and lost intrest in. Tomorrow I will be pulling the motor, fuel tank and transom components and hauling the boat out to pasture

Re: 1972 Silverline Grand Bahama

Don't dump that windshield on the tri-hull either.

 

[boatnut74]

Re: 1972 Silverline Grand Bahama

I did get the one other bunk board put on today. I'm still waiting for my other brackets to come in so I can put the last one on and make final adjustments.

Don't mind the big hole in the back

 

[boatnut74]

Re: 1972 Silverline Grand Bahama

It will stay on the boat. I am dumping the boat in the pasture with all my other "parts" boats incase I ever need anything else.

Re: 1972 Silverline Grand Bahama

Nice donor! W/ twins, are you still going to be using an under deck tank, just larger?

Larger & moving it forward, can give you some assistance w/ the weight of the twins. At the cost of extra long fuel hoses

Bwahahahaa! This forum does have a wonderful curriculum doesn't it?

BN, just found this thread tonight and will be following along. Love the tri-hull cuddy! I'm thinking of two themes for the boat, one is military flat green. Just make it really rugged and ready to go to battle. The other is Austin Powers inspired. Yeah baby, make it shagadelic. LOL


I look forward to following along.

Any way you shake it, two black legs sticking out will be about a million times better than a single white one!
