Rat Bikes! Pub Bikes Beaters! Frankenbikes!

Dom and I modded the stays for Pop's bike:

We measured the stays, used a hammer a block to flatten out the area to be drilled. Then used a hammer and a drift to mark the hole, then drilled it out.

As you can see if gave a beautifully flat rack

i've done the same on every rack. then built an additional strut which connects from the rack to the brake hole on the fork, making for completely rock solid set up... i don't think you have that option though with that fork.
