    Default Little Dipper, frames on stations?

    Hello I'm a first time poster. I'm enjoying looking at different sailboat plans particularly William Atkin's designs and this question may have an obvious answer but I have been reading the Little Dipper article in Motor Boating that someone linked to. Atkin shows in a diagram how to set up the form/molds on station and writes later that frames should be on 11" centers ie on station and between. How can you put frames in where the molds are?

    thanks Phil

    Steam the frames between the station moulds inside the battens. Hang the plank, fastening to the installed frames and removing the battens as you go. Then take out the moulds on the stations and put in the frames where the moulds were.
    It really is quite difficult to build an ugly wooden boat.

    Thanks for your response Nick. I have not seen this little issue dealt with in boatbuilding books so maybe it's a non-issue and the frames can just be installed right next to the molds which would just be 3/4 inch off in this case. What do you think? Phil

    There is no need, just do as I suggested.
    A local builder built small yachts with alternate sawn and steamed frames, They were planked on the sawn frames and the steamed were then installed later. It is not an issue.

    Having the frames a multiple of the stations is nice. I would offset the frames by 1/3rd of a station and then every frame can be bent in without interfering with the molds at all.

    Watch out for the position of the keel bolts. Your floors must miss them.

    Doing it like that how can you clamp the just steamed frames and doesn't it make aligning fastenings difficult?

    The same what that you insert the timbers in a clinker built boat.
