Thread: holiday project

  1. #1

    holiday project

    first of, remembering for those made this country free, and keep it free.
    GOD bless them all


    today due to holiday , sure I don't expect calls...
    I started out with a project..


    on hungary I had a small woodshop and beside other projects I built a couple of dining set for 6 and one for 8..
    I followed a ""conservative"" way, and built with tenoning-mortising..


    I never knew the existence of ""maloof tenoning""


    if I were see only a couple of pics, I would say its no way to work..
    but seeing how much popular I thinkits an another way for furniture building


    so today I started out with this project

    Re: holiday project

    so first I was looking for what I have useable stuff..


    found some yellow pine cutoffs, cypress 6x3 pieces 42 long, and still I have 1/8 1/4 walnut, some cherry 1/8 so everything looking bright..


    I going to make first some smaal chairs without back and arm rest..
    and eventually if I have time some rocking chair too..


    first I glued up some yellow pine to 16x16 (1.5 in thick)
    and some cypress made out to 2 in also 16x16


    while it was drying, I took a look onto how I can figure the joints


    the problem is, at this moment I using scrap wood, and it cant be foretold, what thickness will come out


    so design will be vary within the making..




    I using silo3d, artcam express and mightbe meshmixer for the project..


    but can be considered blender, or autodesk fusion360

    Re: holiday project

    googling ""maloof joint"" we get thoushands of pictures..


    http://web.hypersurf.com/~charlie2/J.../Joinery2.html


    this is the basics..


    on some picture can be seen, maloof also used ""frame"" type seats, not only solid board..




    generally seats are 45 cm tall (17.71 in)


    desk 72 cm !!! (28.34 in)


    dining table vary, from 78-80 cm (30.7 -31.5)




    please note I came from Europe, so in usa it might differ slightly..

    Re: holiday project

    so my way is, first getting the board flat on both side.. that will decide about what heigh the joint made


    for me it came up 36 mm less than 1.5 in
    the cypress I made 46.5 mm and that is 1.83


    however I make the drawing and model to 1.5 in, but it can be modified very simple..


    first I layed out the dimensions in draftsight..
    that's the best program you can use.. because it draws on user defined planes beside the world, and on the standard axis planes too




    chair layout you can open with draftsight


    the drawing , partially was exported as dxf lines, and converted to line obj file..
    imported into silo 3d and modeling could be started..

    Re: holiday project

    so...


    if you open the attached file, I drew first the seat outline, and placed four rectangle where legs are going
    also on the X-Z plane, I drew the ouline of the material thickness..two straight line in angle run down from seat


    between these layed out two arc as leg might be bent.. practically it can be straight, and easy to modifiy to straight, bu tnow I go on this path


    when you import these vectors into silo3d, it will appear as polygons replaced the original arcs, and circles
    its ok, because in silo, or in blender you using faces , or say faceted surface


    also these vectors will be used directly to creating surfaces


    while I know many program works with solids, it could be a forwarn, solids are very sensitive for blending or matching raduses..
    example in solidmodeling sometoime surfaces cant be stiched to a solid, and it can be very daunting


    example rhino a great program, but the clayoo modul made to """fixing""" what solids can not perform..


    so it simpler to start with meshes.. see autodesk fusion 360 where you can work with solids or meshes same time..

    Re: holiday project

    on previous post pictures are not in order..


    the first picture the middle.. it shows the vectors.. and nodes..
    the second would be the 3rd.. shows I made the round edge creating a torus


    im using relatively large facets, due they require small spaces on disc and prior to using model, I subdivide the model..


    the third picture shows I made a mirrored instance of the round edge
    with bridge fuc made one continuous rim and made a top


    to make ""taller"" this model. nee dto select the raidus and top and move with desired distance...




    on this post pictures


    first pic shows derivated from top a part, that will be the front of the joint, also used two vector for the joint matching surface to the inner cuts in the top


    joint can be modeled, it just don't worth..


    next two picture shows how closed up the joint part of the leg..

    Re: holiday project

    ok pictures again not in order, but their numbers are saying the order..
    next 3 pictures shows from the bottom, how transition made, using the vectors from draftsight..


    the great thing is, the universal manipulator can restrain the movement on one axis, also using snap you can align nodes to edges, another nodes, or snapto surface on any point.. and slide on the surface

    Re: holiday project

    I got to the point it can be used in layout..


    I need two different of, the joint head need to be different
    this layout in the file is for 1.5 in top..


    on the pictures you can see the leg top what fitted into the top
    and transition is perfect..
    between the 3/8 top rounding and leg 1/4 rounding




    zipped file is a silo file..


    chair 1_5 top zip






    right now silo3d is offered for 80 dollar..
    it was 40 a little before..

    right or der on pictures see the numbers in the file names

    Re: holiday project

    some update


    on memorial day I could get trough to flatten the tops, so I had their thicknesss..
    the goal is making out of standard 2x yellow pine that has straight grain and closer o hardwood than to spruce..


    so memorial day went with top, and cut the bent legs from one side


    next weekend modeled straight leg and cut one soide..


    yesterday got some extra hours and cut the other sides of legs and groves for joints
