    I have a 23' female mold I must get in to apply the skin coat, I am not a small light fellow so I am looking for ideas for a scaffold for me to get in this mold and apply the skin coat, I thought of hanging some 2x8 across the mold and dropping down verticles to a 2x6 and then running a couple of 2x10 keel wise and working from that,, what do you think??

    I am not too familiar with how to do what you are doing but could you turn the boat upside down and walk under it ? If not ... how about a harness hanging from the ceiling and hover.

    Heck I am thinking I will place some lumber in the mold with the ends protected resting on the chine with lumber laid keel wise, But in the perfect world the mold would be built to rotate

    Your original idea looks OK. You can use a single board that you could slide from side to side to reach the keel. If you have two vertical 2X4 and a horizontal board where the scaffolding sits.

    The "gonzo refinement" is a good idea.
    And this is how the "pro´s" do it:

    Apart the well-engineered scaffolding, the real professionality here is demonstrated by the use of a full-face respirator.
    Something that too many people consider an unnecessary expense, unfortunately (for them).

    The verticals can be 2 x 4s and they can be spread quite wide at the top (3 ft). Instead of 2 x 6s across the bottom, use 1" EMT (metal electric conduit, smashed flat and bolted into the bottom ends of the 2 x 4s). Less height, gets you lower. 2 x 6s are enough up to 10 ft spans, for the beams across the gunwales.

    Well, thats the German way, you know! Do it professional or loose. And this yard is the one with the highest productivity rate in the world. Guess......

    I knew that picture was going to get me in trouble, Daiquiri, I almost never work with out personal protection!, with fresh catridges in the respirator, Thankas you for poiting this out, as it is very important,,

    Well the plank in the hull did not work , I need a better plan as I am running low on ideas
    Thanks the pictures are very helpful but the rotational tools is way out of this glass farmers range I do like the stair stepped walk board

    I have just returned from Korea ,making 36ft match racing yachts and we hung scaffold across the mould and down inside the hull and worked off that while it was being constructed to the stage of fitting the core . then we were able to work on the glass .
    To make the boats and not get any sort of pre-release during its construction the mould had to be set up and not moved untill the hull was totally completed with all its frames in and glassed in place . accuracy was name of the game and what we needed, and got .
    We did the same for making the deck as well worked off scafolding to the core stage
    The hull once taken out of the mould was then set in a fully fiberglass moulded steel framed cradle that was then set completely level and true for rest of the assemble and construction of the completed boat .
    All the boats were as true and straight as is possible to get . Scafolding was just that, steel pipe and scafold planks inside down each side set far enough away from the mould so it was easy to work and not have to streach , Great care has to be taken not to drop any planks onto the hull while you are removing the scafold frame when you dont need it any more . :idea: :p

    You are right! I have been sleeping. I deleted my post! Would be nice if you would do too. No need to stir in the wrong pot!
