I have built several of these for my vintage bamboo fly rods. This one is done with 3/16" thick maple strips, alternated with lacewood. Getting the 30 degree bevel on long thin strips using the table saw was a bit of a safety challenge.
A second challenge was the brackets for the leather handle. They are made of 3/16 brass rod. Filed 45 degree notches, heated, bent and silver soldered. Made the plates of 1/16 brass and soldered the rods in.
Some of the cases have a brass plate on top with initials engraved.
Really a classy way to carry an antique rod on the trips to Montana.
The outside width of the strips on this one is 1 1/4". This yields a case large enough to hold 2 3 piece rods with 2 tips in cloth cases (see photo). A 1" strip width yields a case for a single 2 piece rod. Strips 3/16" thick seems to work best, although 1/4 would be fine, just a little heavier.
