    I have designed some small parts that need machining out of brass.

    I'll cut straight to it, I'm no engineer and nor am I qualified in anyway to design such parts but I do have the basic understanding. The parts have been designed and modelled using Autodesk Inventor and saved as .ipt files, from there I have no clue where to go apart from supply that file to a potential manufacturer to process and move forwards.

    If you feel that you could help me with this process and manufacture the parts, I would love to hear from you. Part files can be emailed to anyone interested.

    I will need help with validating the parts and their possibility of getting made in the first place plus the odd minor question on the parts I am designing.

    I will need 1 of each part made to test fitment and from there it'll be quantities starting at 10-15pcs and potentially more if it takes off.

    I've never done anything like this before so please fire away with any questions you my have and excuse my naivety to it all :)

    Dimensions:

    The parts are around 1.5" wide from memory.

    Hi, I should post up a picture or sketch of some kind to give an indication of what you're after, it may look like 'the queen Mary' or a pin head? personally I can't be of help actually making the parts but you need to give an idea of what machinery may be needed.

    Regards,

    More details are needed.
    Aprox. size, and a couple screen shots would be nice, so people can get an idea of what you're trying to get machined, and if they have the capabilities to do it.

    Max width is around 1.5" on these parts.

    about a dozen times the price of ally.....:cry:

    Yeah I did have an idea that it is much more expensive than more common materials but the purpose of the parts is for adding weight. The specific use is in a radio controlled model, it's common practice to add weights and brass is the material most commonly used, stainless steel is starting to pop up and I'm assuming that's due to the price of brass....

    I've got no idea of the manufacturing process out of the design software so wouldn't even know where to start as far as getting/pricing material goes....

    Couple suggestions regarding the design.

    Does the battery block need all the rounded corners, and does the chamfer have to be flat?
    The reason being the number of tools/positioning that would be needed.
    The vertical rounded corners can be done easily with an endmill, at the same time as the holes are drilled for the threads.
    However the rounded corners on the top, will either need a rounded edge cutter (probably not the proper name, but not a common cutter regardless).
    The chamfer will either need a chamfer cutter (more common than the above cutter, but still not common placE), or for the part to be repositioned at an angle.
    For the chamfer and top rounded corners, if you don't require them smooth, then they could be profile cut with a ball nose cutter which would result in a stepped finish. If needed the steps could be sanded/polished out after, but doing it that way would loose some accuracy.

    The chassis insert looks easy enough, other than would need flipped to get both sides machined.
