I always thought that the American style of longbow had a narrow limb design vs. the semi longbow with a slightly wider and flatter limb core?  One had pretty much straight limbs or a slight string follow design(semi longbow)  and one had slightly re flexed or highly re flexed limbs.( American style)

I can remember when Craig of Howard Hill Archery came out with the Juniper model bow with bamboo, I think I might have rec. one of the first he made.  Point being is that if I remember correctly that bow had a slightly wider limb design at the fades with if I remember correctly a slightly thinner core and a near straight end design.  Trying to locate a note book I kept of all my longbows and measurements of them but I am sure it's history now after 2 moves.    Anyways I am just curious as to what makes what in a semi longbow.  thanks

My understanding is we used a rectangular cross section vs a deep D cross section. Hence American Semi-Longbow vs English Longbow. Think before glass. Narrow yes deep yes.

Wider and thinner to me is a flat bow also normally shorter.

Juniper if a selfbow must be wide like 2 inches to survive, maybe even with glass the trust to go one inch wasn't there. Just me guessing

Beyond the obvious cross section of the limb, the riser is designed to separate the function of the top limb verses the bottom, they have a different rate of flex and the riser connects them to make up the whole!!! Howard would say every part of the bow has to participate!!! Humbly Jacques

P.S. a glass bow without a Buchanon dipped riser, even with a rectangluar cross section would perform and feel very much like an English longbow with it's deep crowned cross section!!!!

I am only referring to glassed longbows.  I do not know what a Buchanon riser is.  I think tiller is what you are referring to as for making the limbs work in unison.  But I do know years ago Earl Hoyt made 3 bows for one of the Olympic shooters he sponsored.  All 3 bows had a different tiller, pos. on the bottom limb, neutral or equal tiller on both limbs and pos tiller on the top limb.  Fella shot the bows without knowing which was which and the shooter could discern no difference in the shooting characteristics between the bows.  I mean Schulz made the American Longbow right, and my JETS remind me of the Trophy Hunters I've owned over the years as for the way the bow looks so I guess I have in my head that is what denotes and American Style longbow.  Some of my old Hill bows as I recall had a wider limb at the fadeouts and wider tips but a thinner core shall I say, almost like the glass did more of the work.  I know Fred Anderson had a formula he used for his bows of certain poundages and how he wanted the drawing characteristics to be depending on core woods etc.etc.  It is listed in one of my old Longbow Mags.  I'll have to try and locate it.  I also recall Schulz had a formula regarding the rule of thirds or something like that for his glassed bows, which I don't recall what that is.  Anyways probably doesn't matter semi longbow vs American longbow.  I like them all.  thanks

The Buchanon dipped riser has been adapted to all Howard Hill bows after, Howard saw Gilman Casey with his Buchanon dipped English longbow!!!

The "American Longbow" is actually sinply the old American Flatbow design as described by Hunt and Metz. Different bowyers over the years have added their own "things" to the design, but at it's foundation that is what it is. 

Even the dimensions of the riser and the working parts of the limb are nearly identical.

I believe the Earl Hoyt tiller experiment that you are mentioning was an exercise that Earl and Rick McKinney did. They actually just used a Hoyt bow with ILF fittings to adjust tiller. Any way,  they adjusted the tiller to as much as 3/8" reverse tiller and the size of the groups that Rick was shooting never changed.

Here's what Howard had to say about it, p. 91 from Hunting the hard Way.

     "There are three distinct types of bows, the straight-end longbow, the short flat bow, and the composite or self recurve bow.  Besides these main types there are many bastard designs that may have some feature of one or all of the other types.  Of all the varying designs and combinations of features there has been only one bow developed in modern times that makes a better hunting bow than the conventional English longbow, and that is the American semi-long bow.

     "This modern type is not quite so long as its English prototype, but a little wider and considerably flatter.  At that, the American semi-long is not so flat as the American Indian short bow, ...."

Yep exactly what I was looking up.  So my conclusion is that the American longbow is a deep cored narrowed limb longbow and the semi longbow is a wider limbed but thinner cored longbow.  Anyways like I said I like them all.
