This was a DIY article...just using our recommendation on parts + good machine work. If a guy buys the core, and the bores are good, mains are good, deck is good, it's EASY!!!! If not, you can correct or try another core...I recommend talking with the Core yard so they know your looking for a pristine core, alot of times they will mark the core, and if you bring it back, they will exchange for another until you find what your looking for.
