Sharp as a Tack
Is nice as your sharping system is it is something that your must have the right stone for your grinder and the type of base mount for the jig to mount in. And when done take off that special wheel and store it till the next time the box of bits is not doing the job.

Don't give up!!!! That's how you learn, by screwing up and doing it all over again. I went through two sets of nice bits before I found the instructions and figured out what to do. If your messing with mini's you have to be somewhat mechanically inclined. Go and buy you some new bits and when you get bored and get some extra cash try out a bit sharpener. once you figure it out it will save you some money. Money that you can put toward the minibikes that your working on.
