    gauge needles

    Put my CNC to work today making these gauge needles, (pointers?). The clear ones are made from vivak and the white ones are styrene. Did some in aluminum, but they really work the homemade CNC.

    Re: gauge needles

    Pet Vivak is a plastic much like lexan, but I believe, a little easier to work with. I can make deeper cuts than I can with lexan. I run the CNC at about 500mm per minute with about 15,000 rpm, no lubrication.

    The batch you are looking at probably took about an hour to finish. Now I have no idea what to do with them. I only need 4 of them for my use. It was just something I decided to give a go. My machine has a problem making perfect circles, but they are acceptable to me.

    Re: gauge needles

    I know this is a bit off topic....

    But would you know how would be best to make the 'aeroplane' in this gauge.

    I have made multiple attempts to produce this 'pointer as it is really' but cannot get the right result...would you have any suggestions?



    Thanks in advance.

    Re: gauge needles

    To my knowledge wing tip to wing tip is around 58mm, height varies on design, so if you fancy playing around with it and seeing if its actually possible to replicate anything like this, then be my guest. Simkits injection mould these parts and I guess a cnc router could produce something similar, its just a fidly part to make, so this could be a challenge...

    But good luck and I wish you all the best! Lol

    Mondo50m, Very nice; thanks for some of the cutting details, what size and type of bit did you use. I am about to finish my CNC machine and the needles for my instrument following MikesflightDeck plans are bugging me. You solution is GREAT.

    Re: gauge needles

    For Tripacer: If you are using MACH3, give me your email address and I will send you the gcodes. They are about 27mm long and 1mm thick. Some are smaller for the smaller gauges.

    For Alex Jay: I will take the infor you gave me and see what I can do.
