Another 25 Seafari goes under the knife - Page 5

Hey Dave

I have some 30 year old wood wedges that my platform brackets are mounted to. I give them the 260lb test every spring. If she holds me, I let her go for another year

But seriously, I could use 4 of those brackets...maybe a new transom..

Keep up the good work

Have not used lacquer sanding sealer since my cabinet spraying days when I was a kid. Did you use an airless to spray that? Looks like they turned out real nice. The brackets that came with my boat are a little small and I thought about making some bigger fiberglass ones at some point....now I have a tutorial to go by.

One of my best buddy's is a structural engineer and when I made my first fiberglass engine bracket I asked him how I could load test it to make sure it would not break. His answer was to bolt it to a wall and get 2-3 big fellas to jump up and down on it...All that school for nothing I thought

One of my favorite pictures:

Keep up the good work

Thanks for the encouraging comments, guys.

Chuck,
First, I want to say thanks again for posting on all your restoration work. This is the first fiberglass part of any size I've ever made. The fact it was a success is a testament to the information you have shared. Until I started following your posts, I had no idea how to use PVA, for instance. Your willingness to share your experience made the difference between a pretty decent part, and what could have been a solid block of fiberglass that wouldn't part from the mold.

If you're interested, I'll ship you my mold and a lay-up schedule after I finish with my brackets.

BTW, I spoke with a guy at a local boat manufacturer the other day and he said to avoid the lacquer. He said polyester resin could bond to it even if you use wax and PVA. My plug separated easily, so either I'm lucky, or it's not a problem when you use enough wax and PVA.

Dave-

Most of what I have learned is from others on these boat forums. When I started restoring boats back in 1988 there was no internet to look for help and I made a lot of mistakes and wasted a lot of money. My first boat was so heavy it rode like a tug boat even though it was a planing hull. I had filled every little nook and cranny with expanding foam because I wanted to make it like a whaler (something I wanted but could not afford at the time)...I still cant believe someone bought that boat from me

Duratec is probably best to use for mold surface. Their sanding primer has lots of uses and tooling is one of them. Also the clear duratec works great if you want to make a semi smooth surface even smoother as a mold surface. Enjoying your thred.

I've been doing some more patching and sanding, but not enough to post yet. I used saw horses and plywood to set up a couple temporary tables in my shop. I found that cutting glass cloth, mixing resin, sanding parts, etc. generates a lot of stuff that has to be moved around. It seemed like I was spending a lot of time moving stuff from one table to the other so I could clean up and move it back. I decided to take a few hours in the evenings this week to make a portable work bench with storage underneath. Here's Before:

Here's the fabrication underway:

The finished frame, on casters:

And the completed bench with stuff stored underneath:

Hopefully, it will improve my productivity.

WTG Dave...
I just love cracker engineering!

Anything to make the job go easier is a good idea..

See ya, Ken

Nice job Dave

Rolling work benches are the greatest. I have a small steel welding table with a large vice on it. Also my drill press and grinder are on wheels too. I'd like to make rolling bases for everything because my shop is small and it gives you a lot more options, depending on what you are working on, and I have this crazy idea that everything should go away after I use it, to leave the shop tidy for the next project...that almost never happens

About the boat...noticed you filled in your thru hulls for your head. Are you going with a porta potty or what are your plans? Our head has a built in holding tank and pump out. I'm going to change it out one day. Silicone is holding the crack for now though

I don't anticipate much need for a head. The boat will mostly be used for day trips. I will probably pick up a porta potty for the occasional overnight trip. I entertained the thought of leaving in the original head, but didn't want to worry about leaks and definitely didn't want to mess with a waste tank.

Did the original head just dump overboard? I believe they outlawed those kind, but, if it was "original" wouldn't it have been grandfathered in??

Yes, they were grandfathered in. Not sure of the current regs. but probably still holds for the originals. You can be sure that since he has changed it, he can't go back -LEGALLY anyways.
