Reed, A lot of others have asked me about the NF2 lately, so I wrote up this couple of paragraphs with information on how it works and who to contact for very complete DIY plans:
The Neufinder 2 is a relatively new, do-it-yourself shaft matching tool you can build for under $100. It has evolved from a spine/NBP finder several of us designed about a year and a half ago, the NF1, a big improvement on existing spine finders at the time. The NF2 makes shaft deflection readings in thousandths of an inch (.0035" is about 1 cpm) and can make repeatable readings to .002" with a little practice. So, it essentially is accurate to about � cpm, or twice that of most frequency analyzers . It also takes all deflections on the NBP, or weakest side of the shaft, automatically, regardless of the amount of shaft trimming. With a frequency analyzer, you have to locate the NBPs and spines on every shaft in a spinefinder first, then frequency match and as you tip trim, the spine location can move and you have to re-spine the shafts again. The dial indicator also can tell you the exact magnitude of the NBP-S1, simply by rotating the shaft and watching the dial indicator. You have to unclamp and reclamp the shaft in a frequency analyzer to do the same operation. Most frequency analyzers have optically based sensors, so you have to have FLO on a shaft to get an accurate reading of flex. The NF2 does not need this extra step. So, all in all, the NF2 is more accurate and at least twice as fast in matching a set of shafts. The NF2 uses the same ABEC 5 skate board bearing sets on self adjusting bearing arms as the NF1 (three sets of four that are always solidly on the shaft), but a different arrangement of the components and several improvements to match shafts and check alignment on already assembled clubs . You can get complete plans, over 8 pages of assembly and operating instructions, 45 digital photos to help with assembly and a complete parts list for $20. First, you inquire to Dan Neubecker, who has developed the NF2, at: [EMAIL PROTECTED] for information. He will e-mail you a response package showing you what the NF2 looks like and telling you how it works. If you want to build it, you send him $20 per his options. Then, he will give you access to the Neufinder Discussion Group, a Yahoo forum for all builders/users of the Neufinders. You also have access to the Group files where all the construction material is stored and can download it at your convenience. This is the biggest bargain in clubmaking today. If you build it accurately, you'll find that it's probably the best and most useful clubmaking tool on your bench. It's not simple...you'll need a drill press and a power saw (table or RA) to build it right. The hardest part is getting all the parts together and making the bearing arms, which must be drilled very accurately. But, only a few parts are internet orders, if you have a good hardware store near you. There's a dial indicator that measures deflection in thousandths from Harbor Freight, skate board bearings from Pleasure Tool and a spring you might have to get from Dan, but that's about all. The rest of the parts are nuts and bolts, washers, aluminum channel and birch plywood that you can find just about anywhere in the US. After you have all the parts and are familiar with the plans and instructions, you can probably build it in a weekend. Good winter project.
