Blueprinted Z101s by Joe K

Well, I just got my first set of blueprinted irons. When I first joined this site several years ago I had no idea what the hell that even meant. Anyways, I bought my satin Zs almost two years ago, and played them only a short time before I bought the Gauge Design 04 forged cbs. I played the Gauge over the Zs because they were on Nippon 950s, and I much preferred them to the Rifles on my Zs.

I have been striking my irons consistently, and as well as I do w/ the Gauge in the bag, I prefer the smaller size of the Z, especially the much thinner topline. So off to Joe to be put on Nippon 1050s. D1.5 on the 2 iron, D2.5 3-9, and D3 on the PW. Lies were a bit upright from the factory so had Joe adjust them down just over one degree. New corded grips selected by weight.

They came a day early yesterday, so I snuck in a quick bucket after work. The difference in feel is amazing. Much more solid and precise at impact. No sponginess at all. Divots were absolutely perfect. I am sold. Blueprinting is absolutely worth the cost!

Now that you know what blueprinting is, could you explain it to me. I'm really interested but have no idea.

I'm curious also. But..........I know what ENGINE blueprinting means! LOL!

Engine blueprinting has become standard procedure in many performance engine shops. Blueprinting is an absolute necessity to obtain maximum power and to insure the longest possible engine life and reliability.

Blueprinting an engine means hand building an engine with perfectly fit components using maximum recommended clearances, and minimum recommended volumes. These specifications should be determined using the engine manufacturer's tolerances for the engine being built.

All parts must be one hundred percent clean. The block should be boiled out making certain water jackets are perfectly clean. All bolt holes should be re-tapped, cleaned and oiled, as well as their mating bolts. Any surfaces being refinished should have all holes chamfered, and any casting burrs or irregularities should be ground away.

I am no expert, but basically, blueprinting ensures consistency throughout the set to exact specifications. So in my case, I told Joe exactly what I wanted on the 6 iron (length, lie, loft, SW, shaft, and grip), and then he works up and down through the other irons matching accordingly. The shafts are measured to ensure consistent flex and weight, and when assembled they are aligned w/ the clubhead to ensure that the shaft flexes as truely as possible. In other words, every shaft will bend best on a specific plane; if the clubhead is misaligned w/ this plane the performance is less consistent.

For most, myself included, this is splitting hairs. I have had stock irons all my life and never had a problem due to a shaft rotated a bit or a slight difference from iron to iron - maybe someday I will be that good to tell. But as a solid iron striker, I can absolutely feel the difference in my Zs after Joe's work.
