    Bedding for steam bent frames

    Should I prime or paint the interior of the hull prior to steam bending my frames? What about bedding compound? The inner keel sits proud of the hull and will leave some limber holes that may be difficult to paint later

    Could you tell us about your project?

    Broadly speaking, bedding compound is a good idea, but the preferred type can vary. If its a new build, there's no need to paint before you put the frames in.
    There's the plan, then there's what actually happens.

        One old school technique (that required a lot of varnish) was to finish the hull, put in the bung, and pour in a gallon of varnish. Then roll the hull round so that the varnish runs over every surface and into every nook and cranny. Then pull the bung and let any unused varnish drain down into the tin.
        It really is quite difficult to build an ugly wooden boat.

          Is that a strip built boat? If the wood is bare, and you plan to have a painted interior, I would paint it now.

            Right, strip built boat, finished product will be a painted interior, I was thinking when I working on building the coaming and deck I will have to sand back off some of the paint to epoxy and screw in supports

              Haha might as well fill a pool with epoxy and sink the boat in it

                Don't recognize the design, but generally speaking, no, do not fuss with bedding steam bent ribs against the hull. If anything perhaps across the apron or against adjoining floor timbers. Yes, oil/prime/paint, or whatever you are doing with the hull interior before laying in the ribs. Coating or soaking the ribs before steaming with turps/linseed or some other form of boat sauce has several advantages.

                  How are the timbers fastened? Glued, clench nailed, or screwed?

                    I think Nick's method wil save having to butter each frame with Luting before it is installed. Dolfinite Bedding compound works for Luting but, it is now quite expensive! A thick mixture of white lead and linseed oil with a bit of whiting mixed in to give it body. Red lead and pine tar are also used when luting frames or other faying surfaces of components if the interior is to be painted. I like Nick's approach better. White lead is available from Kirby Paint Co.

                        Peerie, that’s the boat, instead of the flush hull though I strip built around an inner and outer keel, each strip is epoxied and edge nailed to the adjacent plank, I’ll bend in the frames and fasten with screws from the outsideIMG_6038.jpg

                          I’m sure like drywall I’ll prime the interior and see how unfair it really is and have to start ovebr />

                            I was planning on buying the white oak green as a plank than cutting off the frames as I need it so that the individual frames wouldn’t warp too much before I put them in place, Do you think I should soak each frame in the linseed prior to steaming and installing

                              In which case ensure that you run plenty of primer along the frames so that it will wick in behind them. Not as good as laying her on her side to let it soak in, but as good as you can achieve.
