  • Setting playfield angle without inclinometer

    I'm sure this is nothing new - but I am finally using my high school trig to setup the playfield at the recommended 6.5 degrees.

    I wanted a way to setup my playfield angle without having to get an inclinometer, so worked this out so I can use my normal level.

    A picture tells it better than I could in words - I used a level, a ruler a g-clamp and some maths:

    Oh, and don't scratch your playfield - use some masking tape on any sharp corners....

    Apologies for rough pic - my phone is all I have handy right now for pics

    Good post Thanks

      ****, I think I will just buy the inclinometer

        Pretty simple really. Instead of clamping something at 90deg to the spirit level you could just tape a piece of 35mm wood(very common size) to it at 309.1mm
        Better than lashing out on a tool that you would hardly ever use.Good one askjacob

          True, but lashing out on a tool I hardly ever use might end up being cheaper than fixing a scratched playfield, which is likely to happen in my case

            Fair enough

              OK, this might not be as complicated as I first thought, but let me just check my understanding:

              1) Using a G clamp, clamp a ruler to a spirit level 309.1mm from the left edge of the level.
              2) Make sure the angles between the level and the ruler are 90 degrees.
              3) Make sure the ruler hangs down 35mm from the bottom of the spirit level.
              4) Place the left edge of the spirit level on the playfield, then bring the level down so that the ruler also touches the playfield.
              5) Adjust the front leg levellers as required until the spirit level bubble is exactly in the middle.

              Is this correct?

                yes or find something that is 35mm thick and tape it to the level @ 309.1mm. Less chance of scatching this way.

                  Ummm sorry to be a pain in the arse, but which way would the "something that is 35mm thick" thing be taped to the level?

                    Yeah, thats the ticket.

                    I was hoping to find some nice even numbers, but this was as good as I could get it...

                    It does look a bit over the top at first, but is really quite simple.

                    felixthadog, your description is quite good for the method!

                    For the taping method - intead of the ruler hanging down 35mm at 309.1mm, you would tape the block to the level at that same location.

                    .... or use a wooden ruler rather than metal or plastic to prevent scratching...

                      And who said Maths and Triginometery at school wouldn't come in handy later in life ......

                        A mate of mine who own's a Bally Corvette made a simple little platform with the top being flat and the taper of the flanges being 6.5 used in conjuction with a short spirit level you can set up games across as well as up/slope. Takes about 5 mins to go across the P/F and adust leg levelleres to suit. Any one interested and in this miraculous device we may have a patent pending on it

                          I'll happily purchase a prototype from you now rather than wait for the patent to be approved

                            Is 6.5' the 'universal' recommended angle of all playfields?

                              On my machines the glass looks like it is the same angle as the playfield, so if you didn't want to scratch your playfield, couldn't you just set it up on the glass?
