Ultimate Wheel

I just got my pedal inserts from unicycle.com but now I have a question.
When attaching the inserts to the wood, do you put the sticky-out part thru the wood or do you have it sticking out?

             This..      or.....        This

              -|                             |
               |                             |
               |                             | 
               |                             |
               |-                            |
               |                             |

Do you make a hole for the screws AND the insert or just the screws?

And what do the different colors mean? I got one thats black and one thats grey (I would guess they are for which side it goes on)

sorry that picture didnt work

yeah, i figured that out when i tried to draw ascii the other day… since it’s being posted as html, all the spaces come out.

does anyone know whether there is a way to use <pre>-formatting tags in your posts here? (</pre>)
