The guide can only place as much force against the line as the blank can exert. The tip of the blank, being small in diameter, can exert very little force against the guide or the line. The butt of the rod, being much larger, can exert more force against the guide or the line. To exert force the guide must have resistance supplied by the blank. Placing light wire guides in the lower half of t

Benjamin, If using a standard size tip top use #2 guides Large tip top #3 X large #4 You might also consider a 9 guide set up if the rod will be used for light tippets Gene

Phil, The equation for polar moment of inertia is weight times radius squared equals the polar moment of inertia of the mass. This must be added to the weight distribution of the blank where the center of the radius is the center of the grip where the rotation is about. As the rod deflects the location of the guides relative to the center of rotation reduces in length. This reduces the iner

Phil, I normally target at 6 to 7 times the blank dia. I fill the tube with adhesive and scrape off the excess after application. Gene

Terje, Finish weight is a function of blank diameter. Wraps on the tip will be lighter then in the butt. The finish weight for a double foot guide at the tip will normally be heavier then the weight of the guide. The next step would be to utilize light wire titanium guides. This will reduce guide weight to .03. Going to light wire titanium single foot guides will cut finish weight in half. C

Thanks, gentlemen This appeared a promising candidate but the ERN is too high for a replacement. Still require a 7 to 8 foot rod with an ERN of 7.5 to 8.5. Per Spencer's suggestion I'll expand my search to Batson. The goal is for an 8 weight fly rod for fishing light tippet in windy conditions. Thanks again Gene

Forum: rodboard

John, Correct the stiffness is not linear. The rod deflects from the hand to the tip. The deflection increases due to rod load. The affect is cumulative over the deflected length. You can't change the deflection characteristic of the basic beam. It's built into the blank as a function of OD versus ID over the length of the taper. The load accumulates more deflection the further away from the sup
Forum: rodboard

John, As an Engineer look at the affects of polar moment of inertia and fly wheels. Adding weight to the end of a spring driven system reduces velocity of the tip. A rod is a spring allowing the input of potential energy as the hand is rotated. This torque is transmitted to kinetic energy through blank deflection to the tip of the rod. The energy input by the hand is fixed in velocity versus t
Forum: rodboard

Paul, Base your rod weight decision on the flies you choose to fish with. The fly size and wind resistance will determine the fly line weight you choose. Build the rod to handle the fly line. If he's casting small poppers you can get by with as small as a 5 weight. If he wishes to use large deer-hair offerings a 7 weight is a better choice. If he want's to throw large streamers and bunny fl

Mel, The tip 3-4 guides are light wire single foot titanium of the same size. The rest are tapered larger toward the butt with the stripper the largest. Normally a size 12 double foot stripper. I use a progressive guide distance and believe the greater the distance between guides the greater the variation on entry angle to the guide, therefore the larger the guide diameter required. I've been
Forum: rodboard

Mel, Been there, done that. Still have several rods built that way that have caught many fish. I did experience a reduction in fly line life though. This is most likely due to the contact nature of the guide. Under load while playing a fish the guide acts as a scraper due to it's geometry perpendicular to the rod blank. The snake guides contact the line at an angle distributing load over distan
Forum: rodboard

Mel, I routinely build using single foot light wire titanium for the top 3 or 4 guides, changing to snake further from the tip and insert guides for the stripper and next guide up. I also typically use 9 guides for a 9' rod and 8 for an 8' rod. The blank you are choosing is a nice casting blank and the guide weight reduction at the rod tip only improves upon an already good blank. Quicker rod
Forum: rodboard

Don, Based on the pictures, I'd say the guide geometry caused a combined load and rotation while playing the fish under heavy load. The guide frame height induced a rotational force on the blank while the blank was heavily deflected. The force was concentrated at the blank adjacent to the wraps. The rotational force levered against the blank surface crushing the outer skin of the blank causin

Kelly, Winston is the smoothest. Great finesse. Sage has power and range especially the Method blanks. St Croix is a good choice for an American made blank with a reasonable cost. Tend to cast a line size heavier then rated. The NRX is a great casting rod but haven't seen it sold as a blank. Gene Moore

Gib, Items 7 thru 10 are probably not required. Lure weight and line weight are nebulous and are at the mercy of the fisherman. Distance from tip to reel seat is a variable which may be explored as they determine where flex begins and will have an effect on rod deflection. Been walking this road for a long time. The difference is I wish to determine the performance characteristics mathemati

Very smooth taper design. I presume you are building a 1-hander. Use single foot light wire titanium guides for the tip 4 guides. Shorten the tip top barrel to reduce tip top weight.
