    I steel I have that I'm going to use for the machine has a bit of surface rust from sitting out for the last two years so wanted to try the viniger trick to clean it up. I didn't have any white viniger to hand but did have a bottle of brick cleaner acid so gave that a try and can't believe how well it works! One the design is complete I will cut all the bits to length the pop it all in a tank to soak :)

    After the vinegar bath you can spray WD40 at the inner side since you are going to paint the steel from outside, the rust I see is not that much that is going to cause trouble but it is always good to take precautions.

    i think your supposed to do a alkaline solution after the vinegar or acid to neutralise it and then yes i should probably get something to put on the inside. I will see if i can spray some red oxide in there and if not go for the machine oil option or similar.

    I seam to have stalled a bit on this project as I cant decide a nice way to do the y axis

    from what I read the best option is for the rails to be top and bottom of the gantry

    However in doing that it doesn't make it all that easy to make the mounts for the carriages adjustable and to get everything perfectly lined up.

    what do people do to solve this as it seams most people use this configuration?Click image for larger version.

    Hi dean

    thanks for that

    If I can go for that rail setup with one on the top and one on the front it would make life a lot easier!

    It was only a first sketch so I can easily bump up the size of the section if needs

    Hi Charlieuk,



    I have the same thing to think about.

    I think i am gonna use set screws in the stationary Z plate pointing at the side of the top and bottom carriages.

    So i need a little extra room in the bolt holes in top and bottom mounting plates.

    Setscrews will be removed after i am satisfied things are square and torqued down, before moving part of z axis is mounted.


    Grtz Bert.
