Title: 4 position switch increments and aligning text to the increments?
Post by: GhostofJohnToad on May 07, 2013, 08:02:43 PM
So I am working on finishing up my ZPSDX and am trying to figure out the placement for the text descriptions for the 4 different modes.  How are you guys doing this?  Is there a specific angle increment the switches are keyed to?  Or are you guys just trial and error'ing it.

Trial and error man, it will really depend on the size of the knob you are using.

I print my designs out on paper, cut holes where the pots are, put the knobs on, make sure it s right.  I'll do this quite a few times before I'm satisfied.

only when I'm happy with my paper version do I get attempt to etch a faceplate, make a waterslide, etch the case, etc.

If you look at the zpsdx I have just completed,  you will see a white chicken head and it is way to big... but I only used it as I am waiting for some smaller knobs I ordered.

As aballen said it is trial and error, just put a knob on it and measure the arc as you rotate the switch...you will get a rough idea of the size you require.

The switches i have are all 12 position based, whether 1 x 12 or 4 x 3, a tabbed washer acts as a position stop preventing it from switching to too many positions. So... 360°/12= 30° between stops.

To create a label using simple CAD software,

Draw a circle slightly greater in diameter then the switch's mounting hole. Based on the same center point draw a second slightly larger in diameter then the knob you want to use.

Draw a ray from the circle center to the 9 o'clock position extend it to just past the outer circle and stop it at the point where you want your legending word to end.

Highlight the ray, the software will have provisions for radially copying the ray around the center point of your circles. You'll end up with 12 same length rays emanating from the center of your circle 30° apart, your position markers.

For, 4 positions, oriented to the side, you'll probably want to rotate the whole deal 15°.

Label your four rays. Dress it up however you want.

Delete everything you don't want to be seen but not the small circle and crosshairs as you'll need them to position the label/decal.

brilliant.

I need a tutorial on how to do the ray thing in inkscape. And cross hairs.

Fantastic davent!  That's exactly what I was looking for!

I don't mind the trial and error method if I have to but... I love a well thought out plan.

Awesome little how-to, davent. Definitely going into the "things I need to know" file.

Now if I could just figure out how to do that in Photoshop/Illustrator.....:o

That's so much better than my way :)

I use a similar method in Illustrator.  It's really not too bad.  Just draw the circle and then add the lines.  You can do it by  adding each individual line at defined angles or you can copy some of them and rotate them as needed.  Instead of deleting the template, I usually put it on a separate alignment layer and hide it before I print or make it non-printable.

Hey GhostofJohnToad,

I posted this some time ago.  Its a group of knob dials i made in fireworks.  It's a png so you can edit them any way you like.

Hope it helps!
