Re: Stus-List Bottom paint removal

Didn't think of the shop vac!

I'll see if I can make that fit to the sander this year.  Now that the snow has receded it will be a rush to try and clean up the new boat and be ready to splash in the next few weeks. 

Good news - the ocean out here does not look like Lake Superior.  May be the same temp! but not frozen.

I think the (Bahco) scrapers make sense when there is a heavy buildup of paint. I use VC 17, this year trying Pettit 22, and they have virtually NO buildup. So I just use an Random Orbital Sander like you, only I hook the shop vac onto the sander, and I am almost as clean after sanding as before.

I know sucking in the dust from scraping the bottom is not good - but in the past I've used a random orbital sander with a fairly rough grit paper (and a mask)
Seems to go pretty quickly, or at least it did on my little 24'

Are scrapers preferred?  I'd have thought the finish would be much rougher.

Hi,

 

Scraping off bottom paint is a pain with a cheap steel scraper.  Once has to nearly sharpen the blade ever other second.   This year I discover using a good tool really matters.    

 

Don't use a steel scraper, pay the $23 and get a tungsten carbide scraper.  One blade will last a whole side of the boat or more.  I was amazed.

 

Here is a link to a scraper I used on a 38LF.  Bahco 665 Carbide Edged Heavy-Duty Paint Scraper

I got adventurous this year and decided to remove as much of the existing bottom paint as possible. There are many layers on the boat that have accumulated over time. Ordinary manual scrapers take a lot of time and energy, and sharpening. I developed this scraper which will fit in any reciprocating saw and uses a carbide blade. It is a lot easier and quicker and the blades last much longer than regular steel blades.

Here?s a video: https://www.youtube.com/watch?v=_2lsNuCrfgk

Now, all I have to do is get at it as soon as the rain stops for a few days and the temperature becomes bearable.
