Flat Sided Vs Round Side Crank Action

Recommended Posts

Ok now that I know uranium is the way to go with my crankbait weighting another question?   :rolleyes:

 

What is the difference in wobble  between flat sides and round in crank action? I'm looking to make some for shallow SM bass. Two different types, Mann Baby -1 0-1ft and Bagley Honey B 0-4ft depth.

 

Templates for round sides, yes?

Flat sided cranks have more side-to-side resistance and a tighter wobble, while rounded cranks tend to have less side resistance, so wider wobble.  There are various ways to round a body.  Through experience, I've found that is is almost impossible for me to round over a bait all by eye and get it symmetrical, especially in a wood that has any visible grain structure.  And symmetry is critical.  Some guys do a top template to guide how the bait will be tapered.  Then they cut facets at the corners of the square blank to make it octagonal, then round those over to a cylinder cross-section.  That's basically what I do.  In the long run, it's worth going to the trouble to do templates and mark your cuts.  Even with the marks, you still have to eyeball it to feather out the facet cuts in the nose and tail of the bait.

In theory rounded is the way to go for more action and they certainly look much better. But the last lure project I did was flat sided, just to explore for myself. I was pleasantly surprised that the action was very good, although a side-by-side comparison was not made. Maybe a future project.

 

Until I get my duplicator re-built, any lures I produce for my experiments will be flat sided, mainly because repeatability is so important and I hate carving.

There's more to the action of a bait than just whether the sides are rounded or flat. I've built a couple of flat sided baits that looked almost as if they were going to swap ends they had such a wide swing. I can't explain all of what goes into giving a lure the action it has, but I do know that the location of the ballast plays a big role. If you can get the baits center of gravity and center of mass to line up it will give you everything that style and shape of bait has to offer as far as action goes.

I think baits can have several areas of physical appeal to bass:  size, visual action, hydrodynamic signature, sound, etc.  Conventional wisdom is to use a tight action lure in cooler water, a wide action lure in warmer water.  But I catch fish with flat sided tight action lures year round, including in summer when bass won't hit a rounded fat bodied wide action lure.  The opposite doesn't usually apply in cold water, at least for me, so I've developed a bias toward using flat sided crankbaits.

When I'm fishing off peak times, I've noticed that a jointed round sided crank has been more effective for me than its straight version.  That being said, a straight flat sided bait will be my go to bait as it has produced for me time after time.  I have yet to build a jointed flat sided crank so I a can't comment on its effectiveness vs its straight counterpart.

Ok let's assume I want to make some flat sided balsa cranks around 2 to 2 1/4 inches. How thick would you recommend to start experimenting?

 

I have found very little on the web in the way of specifics, only a pattern and great instructions for a 2 1/2" from Paul Adams. It's 2 1/2" long with 1/2 balsa used. But then again I have some 1 1/4" basswood blanks from Whittler that are 1/2". Not too many anymore. :-)

 

Another question, is the belly weight hangar a spot to start with ballast placement?

You can go to any width you like but as they get "too wide" they begin to look blocky unless you round them over more, which sort of defeats the purpose of a flat sided crank.  One of the most famous flat sided cranks was the D-Bait by Gary Dees.  They were just over 1/4" in width and many of the best known flat siders are similar.  It's a balancing act.  Less than 1/4" wide and it becomes hard to ballast them.  Also, the thinner they are, the more poorly they tend to cast.  But the thicker they get, the less realistic the profile of the bait becomes and the less lively the action tends to be.  As to ballast position, 99% of balsa flat sided cranks use an integral belly hanger/ballast.

 

Of course, none of the above dictates how you need to build YOUR bait.  A lot of the "classic" flat sided baits are built the way they are due to commercial considerations, not purely for performance reasons.
