|ROD BUILDING MASTER CLASS Building a bamboo fly-rod Part 4
FOLLOWING on from Part 3 in the previous issue, you should by now have a completed tip and butt section, just waiting to be finished into a useable fly-rod. Well done if you have reached this point. Compared to building the blank, the remainder of the steps involved are relatively easy and your new fly-rod should be ready shortly.
Before the ferrule can be installed, the blank should be cut to length and prepared to accept the ferrules. The object is to end up with two sections that are exactly equal in length when broken down and of the correct length when assembled.
In the previous issue we determined where on the blank the target dimensions were reached. Before we cut the blank we have to determine where to make the cuts by accounting for the ferrule.
CUTTING THE BLANK TO LENGTH
The male portion of the ferrule is installed on the tip section while the female portion is installed on the butt section. Follow these easy steps to find the correct cutting points:
Measure the length of the male slide with digital vernier calipers.
Divide this length by 2. With the ferrule that I used the male slide was 0.800. I ended up with a value of 0.400 when divided it in half.
Now add the value that you worked out in the previous step (0.400 in this example) to the tip section length and make a mark in the new location. This is where you will cut the tip section.
Reduce the length of the butt section by the value that you worked out previously (0.400) and make a mark in this location. This is where you will cut the butt section.
Use a small hacksaw to cut the blank sections to length, taking great care to cut each face of the blank in order to prevent tearing of the surface power fibres.
PREPARING THE BLANK TO ACCEPT THE FERRULE
Now that the blank has been cut, you should prepare the blank where the ferrule will be installed. In order for the ferrule to fit, the blank has to be rounded to the correct dimension. If you selected the correct ferrule for the blank that you are building, you will be able to achieve a round cross section without excessively cutting into the power fibres.
Start by measuring how far the ferrule will slide onto the blank when fully installed. Mask the blank immediately adjacent with masking tape for protection, and proceed to remove the six corners from the area with a small file. Once all six corners have been removed, take a piece of 220 grit wet and dry paper and fold it around the section that has to be rounded. Now turn the blank with your other hand to achieve a perfectly even circular cross section.
