    Brilliant:) From what I can see, stainless has over twice the strength of brass and also takes twice the power to deform permanently. Thank you :grin:
  2. Best spline type - rotational force into plastic

    Long story short, I'm having trouble conceiving how to transmit rotational force into a plastic 'adapter'. Your advice is greatly appreciated.

    A handle has a splined plastic adapter between it and...

    In the absence of doing anything practical such as Hudson's suggestion, I'd personally focus on the colour. It's that that gives it away for me. Stainless is very rarely chrome plated so simply...

    Thank you for the idea. For what YOU have described, it's a great possibility.

    I fear however that I have inadvertently mislead you all so time to be a little clearer.

    They do it through light pipes. The LEDs are on a board and the perspex, or whatever, light pipe is shaped so it gathers the light and presents it at the end as you see.
  8. Small thread advice - anti loosening

    Hi

    First off I have searched. The searching has made me fully realise (vs only suspecting) that this subject is not simple but that I want to learn, to understand. Thanks.

    I have a small...

    Hi Hudson

    Thank you so much.

    I have managed to find DIN 5481 which kinda feels right. From further reading I understand one calculates the pin dia as it must touch at some 'magical' point (or...

    Many thanks for those. I had found some not others.

    Confession time. I can't make head nor tail of it all. From what I can see, that seems to be for 'proper' splines, splines designed to transmit...
  11. 'simple' spline calculation help pls

    Would someone be kind enough to point me to where I might be able to learn how to specify some simple splines?

    It's not complicated. However one part must be changeable. Hence the join.

    I'm not doing anything 'special' I agree. Tap in this instance is your faucet, so the forces involved are turning and typical of those involved in the daily use of a faucet.

    As I'm looking to...

    Thank you peeps.

    COD. Hmm. I have to be careful describing the use due to wanting to protect what I'm doing. Suffice to say, the side with the splines on will have a tap head attached and the...
