    geeze... I did mine the hard way... had to dig deep to remember circle maths lol

    Mine is 2 tracks. 1 up, 1 down.

    47 inches total distance from lower layout to upper. 2.25" between levels. From my maths, around 23 levels to climb. Uggh...

    47" climb? Wow, that's quite a helix. Got pics?

    I brainfarted... I guess ive been living in this thing for far too long. I'll call it a senior moment.. I had to get one of my n scale sets out of the overhead cabinets in the rear of the living room today... the exact same cabinets that are essentially in the way of the upper layers of the helix I have been drawing out and planning off and on.... for a week..

    Yeah... proby slap time. I've lost count of how many times I've measured that space... not even looking at the cabinets.. lol! Oops..

    Sooo... rev4 change 6... new hieght of helix=35 inches

    14 rings total. but that also means I'll have to transition from a shelf layout to a hanging layout. The good news is that it's still well above the tv in the entertainment center lol

    Is there a headroom issue with the cabinet?
    Before you get it drawn and cut, make sure where the helix is placed, when you stand inside it, you don't have to crane or bend your neck uncomfortably to work around the cabinet.
    Rev 4, change 7? :p

    No, headroom isnt the problem.. just simply didnt take the cabinets into account.

    And hanging the upper layout lower will actually work out better in the end. it'll still be out of the way, but much easier to work with.
