The IOBO Humpy

The CdC IOBO Humpy

must be one of the world’s greatest dry flies. It is incredibly simple to tie yet unbelievably effective since in various sizes it imitates/suggests a host of insects (Midges, Aphids, fluttering Stoneflies, Fluttering Caddis Flies, emerging Olives, Olive Duns, Black Gnats & others).

IOBO stands for It Oughta Be Outlawed,

it is that good. It was devised in the mid 1990s by Pennsylvanian Jack Tucker. Dutch flytyer, Hans Weilenmann, has put a video on You Tube that shows Jack’s original method of tying. My method is very different, but the resultant fly is virtually identical. I modified the tying method to make it easier to judge accurately the wing length, also to facilitate the easy forming of 2 slightly splayed wings to ensure that it landed correctly every cast & also to allow thin or fat bodied variants to be tied (I virtually always use thin bodied variants). In recent correspondence with Jack (when he kindly contacted me to thank me for crediting him with the pattern in an article for FF&FT magazine) he very generously said that he preferred my method of tying.

Hook:

 

Thread:

  • 8/0 Tan or yellow Uni thread.

1. Wind thread from short of the eye to the bend. ( I like to wax the thread first). Then tie in two CdC feathers (natural gray) with 2 loose turns. Pull the CdC feathers towards the eye till the tips are about 11/2 to 2x the shank length. (Match the size of CdC feathers with the hook size).

2. Tie in CdC with 2 or 3 more tight turns. Then wind the thread to just short of the eye in open turns over the feather butts. Trim off any remaining butts.

3. Pull the CdC “tail” forwards (over the back) & tie in with 3 to 5 tight turns. Whip finish in front of wing to push it up slightly, as shown. I like to leave a few trailing CdC fibres as a ‘tail/shuck’ (not on the original pattern).

I tie it in sizes 26 to 12 (mainly 24 to 18).

When fishing CdC flies ignore all the erroneous advice that CdC flies are useless for more than one fish after they get slimed up. Follow the sequence below & you should be able to catch loads of fish on the same fly, even on a wet day.

  • Rinse the slimed up/soaked fly thoroughly in the river/lake.
  • Squeeze hard in a piece of absorbent kitchen paper (much cheaper than amadou & when it gets dirty it can be discarded. Old amadou gets impregnated with hydrophilic slime & dirt, which render it useless).
  • Rub vigorously with the kitchen paper & blow to open up the fibres (CdC is very tough!)
  • Apply a tiny drop of Roman Moser Miracle Float (available from Stu Wardle at Durham Flyfishing Company) or slightly less effective a drop of CdC oil or Tiemco Dry Magic onto your forefinger. Spread thinly between thumb & forefinger.
  • Rub into the CdC.

FISH ON.

The IOBO Humpy, Shuttlecock, F Fly & Hackleless Elk Hair Caddis

are my four most used dry flies & I would be devastated if I was unable to use them.

Grayling are suckers for a size 20 to 24 IOBO Humpy but in my next Blog I’ll be talking about sight fishing for big grayling with nymphs, shrimps & bugs.

    3d Models Explained 3D modeling may be designed for military simulations too. Architectural 3D modeling lets you need to an early view of design and therefore, you can do get benefited by having several 3D modeled design options to select straight from. Models made by MEP designers might not be spatially accurate enough during early phases. It might not possible to create models for each and every aspect of the plan, causing an incomplete general pictures.

    There are two major methods for creating 3D models in Blender a model in 3d. Often 3D models end up being beneficial to evaluate certain crucial things including product information, its manufacturing expenses, and designing concept. Nowadays 3D models are attending to be one of the most effective tool utilized for marketing any sort of solution possibly firm or any industry it may be. Such 3D models will be simplest approach to spell out how building structure will from various angles and views. Stereoscopic 3D models may even be customized. Functional 3D models are made with the bottom up, 1 layer once.

    You are able to sell 1 3D model repeatedly and all over again! 3D models may be employed for educational purposes of course. Utilizing 3D models on on the internet site one is more inclined to capture the eye of any client.

    A Secret Weapon for 3d Models

    3D modeling may be for military simulations too. Architectural 3D modeling lets possess an early view of design and therefore, you are able to get benefited by having several 3D modeled design options to select totally from. Models made by MEP designers might not be spatially accurate enough during the early phases. It might never be possible to create models for each and every aspect of the plan, causing an incomplete general vision.

    There are two major methods for creating 3D models in Blender 3 dimensional. Often 3D models end up being beneficial to evaluate certain crucial things including product information, its manufacturing expenses, and designing concept. Nowadays 3D models are attacking be probably the most effective tool utilized for marketing just about any solution toned man walking firm or any industry it could be. Such 3D models are the simplest technique for spell out how building structure can be from various angles and views. Stereoscopic 3D models may be customized. Functional 3D models are created the bottom up, 1 layer optimisation.

    You ‘re able to sell 1 3D model repeatedly and once again! 3D models may double for educational purposes conjointly. Utilizing 3D models on a world wide web site a lot inclined to capture a person’s eye of a possible client.

    3d Models Fundamentals Explained 3ds Max renderings are popular in the discipline of architecture. Attention-grabbing animation can actually assist you to go quite a distance besides your hemorrhoids . 3D modeling, you will receive to reveal your clients how your product elements. 3D animation is a superb means to take an extremely tricky concept that would be challenging to relate verbally and turn it suitable into a simple to understand 3D image. 3D animation in most cases refer to the art of producing and modifying the images. It utilize many of the same rendering techniques that 2D animation does. So might be wise to learn about computer 3d animation as well as to the basic fundamentals of 2D before you go out and get yourself any package. Choosing 3d Models The processes are alike, only the particular keys and commands are different. The 3D printing procedure starts from many of projects from MIT in 2000.

The computer at the house, the cell phone you use, the car that you drive, and the list continues on and on. The software employed in building projects varies from nation to nation.

    3d Models – the Story Almost all 3D computer work is done with distinct kinds of animation program. The utilization of 3D imaging is beneficial to the business that wishes to present a model associated with the item like a vehicle or a building. The usage of parametric 3D models as compared to poly-lines helps to acquire accurate data from the project which can subsequently be used for procurement purposes.
