1999 Crestliner Project

All you need is a MIG welder and a bottle of Argon. Watch a few YouTube videos and give it a shot. It's what I did, and now I'm pretty comfortable welding aluminum

Thanks, I like the setup as well. It is a bit dated, but with some new materials it will be perfect.
That flip up cover covered the old stereo. The new ones are round. I want to see if I can repurpose it for something else.

I would be a great place to put a fuse block, and have room leftover.

Thank you. I thought about it. I am comfortable welding steel, but have not tried aluminum. I do have a lincoln 160 welder from homedepot. Not sure if it will be enough. I will need to get a spool gun as well as the Argon bottle. About 3-400 around here. Decisions decisions...

Working on the transom today.
It is made of the 3 pieces of 5/8 ply. I have made one piece to exact size and 2 other about 1/4inch wider, so I do not to go crazy aligning them during glue up.
Not very happy with the plywood, as I have used ACX from local building center and it had 7 layers (which is 2 more then original) but had paper thin final layer of on the top and bottom. Not sure it it will delamenate, but it only acx I could find in 5/8.
Today glue was dry and clamps removed. I have trimmed the sticking out pieces flush with the top layer.
Before I glued it all I have installed the single layer in The boat and marked the holes. I wanted to drill them so I can soak them in the OTF.
Transom will have a very tight fit and i am not sure i can oull it out after hammering it in. I also hope that original holes were drilled perpendicular to the transom. Otherwise the holes will not lone up on the back.
Next was mixing some Old Timers Formula. I thought it would be 30 minute job to cover all areas with OTF, but it turned into 4 hour job. The edges on the ply were soaking in otf like crazy. At the end, I have went through 3 quarts of otf! And 90% of it went into end grain. I think I could have soaked even more, but I was so beat that it had to do.
I have layed the transom flat, plugged each the hole with my finger from the bottom and poured otf in. Had to top off each hole couple times, waited a minute or so for each hole and moved to the next one.
Tomorrow will do another soaking and will let it dry before doing straight spar.
Thanks for staying with me, guys!

Thanks. I do not weld aluminum, nor know anyone who can can do odd jobs like that. I will have to find someone to weld the transom cover anyways, as it had to be cut for it to come out. So it all depends on the sequence of steps. If I will be able to do this all at the same time, I will do it.
Few of the cracks are right next to foam, it think I will bolt those up to prevent fire.

I think a professional welder could weld it quick enough to minimize on heat. Aluminum sinks the heat away quickly anyway. Perhaps a little melting but, I doubt if it would catch fire.

I think I might do a little shaving so it fits without having to hammer it in place.

It is not the width, it is thickness. The original transom is even thicker, but I think the aluminum on outer skin deformed a bit when the old transom rotted.
Some screw holes pulled inwards. I will try to pull them back to flat.

Check your local radiator repair shop, often they are aluminum welding experts !

Lots of work and effort goes into those builds, great job! I agree that welding would be the best way to repair those cracks.
You will have a wonderful boat when you are done, Crestliner makes a great boat IMO.

 

[navipro]

Yep, I think I am at about 100 hours so far and nowhere near even starting to put things back together.
Here is a little jig i made to repair the holes that were pulled in on the transom.

Here is an little Easter egg from the factory. On the inside of the transom it says Daryl's Boat. Well, whoever you are Mr Daryl, nice to meet you over 25 years.

You don't need a spool gun unless you are building a whole boat or doing a lot of it. Look up some youtube videos, but all you REALLY need is argon and you must oversize your tip so the wire doesn't bind, and try to keep the lead as straight as possible, with no hard bends that could bind the softer wire.

I think you will really enjoy doing it yourself. Play around with some scrap and then get it done. You have to move so fast that it's almost disappointing. You think about it, worry a little, study and prepare, and then it's done in 90 seconds. But then you realize that you have a new super-power, AAARRRGGHHH, YESSS!!!!

I wonder if it was Daryl or his other brother Daryl.
