place the wheel on a table with the face of the wheel upward.you will need an xacto knife with at least 2 - 3 no.11 blades brand new.
the rear wheels had a little lip that i was able to use as a guide to go around the wheel very lightly with the dull side of the blade.make sure you hold the knife straight up and down. i held the knife in place while i spun the wheel around with my other hand.it took me like 10 mins for each one.you have to take your time.and use the tip of the dull side as you spin the wheel and hold the knife apply pressure downward keep checking the inside of the wheel until your almost all the way through .now you can use the sharp side and cut very slowly until the center pops out.the front ones barley had a lip i kept slipping a few times until i got a groove to follow take your time with the front ones take your time period. you'll be happy with th results.this is the first time i tried it,i had these wheels for almost a year i had the idea since i first saw them i'm happy with the way they turned out.i will probably paint the center and bmf the lips should look pretty cool when they're done.
thanks for the nice comments guys and thanks for looking!!!!
