Thanks for sharing your experience, I like their colors also.
Cutting my seat bases from 1/2 MDO plywood. All job took 25 minutes to cut.
Deck with holes to pour the foam and after job was done.
Can I borrow your CNC?
MDO ply, great for interior but polyester/ glass doesn't stick to the paper too well and the paper lifts from the wood over time too. Better plain ply. In my experience.
Re: MDO vs Marine Plywood?
Should do just fine, Chris Craft used a good quality MDO in many of their Sea Skiff boats over the years, above the waterline, for a long time, and it's held up just fine. As long as it's a good grade, and you seal it well, it is fine.
Commercial yards use MDO in some of their yachts and big ships, it's heavier, but also cheaper. It's less practical to use in smaller boats though, as you often have to curve the pieces, which is more difficult to do with the MDO.

To bad Kevin, I would have to go with it.
My boats main bulkheads where build from the MDO also, that's why I went with it. I'm planing to paint seat bases with top side paint.
They are very easy to build using the CNC router and put together using Kregs pocket screws and glue.
MDO, I was talking about polyester/fiberglass over it not paint
Need to hot coat MDO, IMO. If you don't do that....I bet the paper just sucks the resin out of the layup if you don't. It's pretty slick and glossy too. Maybe some tooth put into it would help also.
? Not sure what you mean. :}
"Going down and under". I pick up four boat stands on the Craigslist past weekend for $ 250.00 and I took her of the trailer to start working
on the manufacturing a new keel. I will be using Sapele wood for that and i need to clean and paint the bottom. I got price of $950.00 for media blasting and
I think it is way to much money. I will try to call another guy to get price from him. Will see.
Here are a few pictures of my progress.
The $950 for media blasting will be well worth it. I tried to save some money by doing my 22' sailboat myself and it took me many many hours to scrap with a carbide scraper, orbital sand, and then I used a grinder with ceramic discs to get down to the original gelcoat on the bottom. Trust me- you only do this once and learn that when your time is money- soda blast and be happy to pay the guy IMHO.
Yup. I took the do it myself route. It is the last bottom job I will diy ever!!!! Pay the cash to make it someone else’s labor.
I think I agree with you guys on the soda blasting, it just looks like there is small area to soda blast it to justify money spend.
I try to get couple more quotes.
I assembly one of my seat bases yesterday and it fits like a glove. I used Kregs pocket screws a Trident glue. I am also planing to reinforced inside corners with
Epoxy and 1708. Out side will be just painted.
why epoxy and 1708? Use PE or skip the 7.5 oz mat on the 1708. Just trying to save some $$$.
I have leftover Raka epoxy laying around and I have a tons of the CSM and 1708 leftover also. The seat bases fell pretty solid, but I use 1/2 MDO plywood and I will sleep better at night knowing that I reinforced it with some extra fiberglass tabbing.
Hi all, remember me. LOL. I still didn't give up on this project and as a matter of fact I was working on her as much as I could.
Just a little update, all decks are in screwed and glued, port and starboard sides from transom to the bow are filled with 2lb foam.
Cabin deck has a fiberglass layer on it, cockpit deck still needs one after I will make engine compartment bulkhead.
This weekend I started to put cabin interior to the original design. I think it looks like the original one. I still have to finish painting
porta potti compartment in white and under the V berths in gray. For some reason the paint was still tacky today.
Next weekend I will tackle the engine compartment bulk. It will be a challenge.
Here are a few photos from this weekend's work.
