150 lb yew
Rod:
Actually the source of my comment about bending an eraser was doing so many years ago, as I'm sure many of us did at school.
I did not immediately make the connection, until one or two sharp edged bows broke by lifting at the corners, where a bow with rounded corners did not.
This was subsequently reinforced by two gentlemen of my acquaintance who are, but would never claim to be "master bowyers".
Quite a few years subsequently it was interesting but not surprising to read the item to which you refer in TTBB.
I note your comments about balance, and will only say that there is no shortage of positive comment on this particular thread and I did not in this instance choose to add to it.
Since I have no use for a 150 lb bow at this time, it may be a long wait.
But if you care to introduce yourself at an NFAS meeting I would be happy to shoot with you.
I still take the odd Sunday off and get out occasionally.
Rod.

Nice looking bow Henry. I made a 95#@30" yew bow a few years ago but I could not pull it. ::) I gave it back to the guy that gave me the stave. ;)
If you round the edged along the back it will add some protection from raising a splinter and should not reduce the weight at all. That area, along the edges is dead weight on a bow. A good rule of thumb is ..."the diameter of a pea"..1/4" or less. Generally I will use my scraper to remove the very edge with one scrape and then one scrape just below that one and another just above. A light sanding will smooth to a nice rounded edge.
Lukasz Nawalny:
ok , thanks.
Rod:
The "diameter of a small pea" would typically apply to the radiussing of the corners on a flat backed bow, such as we commonly see with a hickory backing lamination.
I would expect a yew self bow to me more rounded out, but there is also a good deal of variety in known cross sections.
Rod.

I'd like to add that the discovery of this goes back to the first half of the 19th century. It is also discussed in probably every mechanics book that covers the bending of beams, so it is not really a great new discovery.
