If it is a shooter, chop away! I have not done a featherweight forend tip, but I have done many others... it is no great trick... chop saw it at 45 degrees, without moving the blade, cut into the tip block so that the resulting angles equal 180... clamp the stock down and the apply wood glue to both pieces, wait until tacky then clamp down the tip... put a piece of printer paper under the joint so your stock doesn't become a permanent guest at your wife's dining room table... I use a homemade jig for this with a side wall to keep the pieces lined up laterally... I like to use Bubinga, Cocobolo, walnut, zebrawood, and verawood for tips... once set, cut the barrel channel in the tip block, shape the outside contour and sand to blend it to the original stock, then do the final barrel fitting and finally 6-8 coats of Tru Oil... easy, peasy, mo-beasy.
Hint... cut more than one tip block...
