    Got a few handrails and spindles to fit on a deck. Can anyone help me out with the easiest way to have equal spaces. For example one of them from inside post to post is 1700mm don't particularly need a spindle tight to post. Looked on YouTube but not making sense. Many thanks.

    Decide how many spindles you want, add 1 to that number and then divide the distance between the posts with that number hence centres between spindles and edge of posts i.e. 16 posts, divide 1700 by 17 is 100

    How do i know how many spin dles I want. That's the part I don't grasp.I thought if I required say a space of 80mm then the thickness of the spindle divide by say 1700.doing my head in to be honest

    Umm... not quite. Take this example : space between newels 2340, 16 spindles @ 40mm each width. 2340 - (16x40) leaves 1700 for the spacing.. 16 spindles so 17 spaces... So 100mm spacing between each spindle... which is the maximum recommendation for stair regs ( part K) so a baby's head can't pass through them.

    Without taking babies heads into account a fencer once told me, lay one in the middle of the total length, then another in the middle of the new length and so on. So whatever length you have always place one in the middle until it looks right.

    Regarding the babies heads - you must not be able to pass a 100mm diameter sphere at any point between the spindles so if they narrow or taper at all in the design you must take that into account.

    Thanks for that but how did you come up with the 16 spindles

    substitute your clearspan substitute your number of spindles substitute your spindle thickness do the calculation if it comes up over 100 add a spindle and try again

    Maths, he cheated where did 2340 come from is the question you should ask lol.

    Let’s take your 1700.
    Start with 100mm space. 1700-100= 1600 now divide by spindle + space. So 1600 /140= 11.42, bugger not a whole number but if we use the next whole number as the number of spindles.
    12 spindles @ 40mm is 480mm. So 1700-480 is 1220. Now divide that by spindles +1, 1220/13 gives you 93.85 mm spacing for 12 spindles

    My problem was I could not even find the app, let alone use it:)

    Yeah but because why we know it works we can apply the principle to other situations - so our knowledge is portable and transferable. Young trade people today want an app for everything so don't develop these skills. you can be pretty sure that tosspot troll thats just appeared above needs a calculator to work out 6 x 7 because that's 'too long'
