I was hoping to get out this weekend so I could provide a solid update on central Alberta trout streams but there was just too much happening on the home-front. Creeks closer to home were running high and muddy, and I am guessing things were about the same out west. Hopefully next weekend will work out.
I did however get a chance to do some sanding on the wood fly rod blank. It is coming along nicely - the tip section just needs a little more work and then it will be ready to laminate.

Part 5: Sanding to Taper
Aside from a few angling excursions over the past few weeks,
I have also spent some time working on the wood fly rod build. The project
continued with part 5 which involves sanding the rod blank down to the desired
taper. This is one of the more intricate and lengthy stages of the process that
is best accomplished by working on it a little at a time – sanding for a half
hour or so whenever time allows. The goal at this stage is to bring the rod
blank to a point where the rod has the general flex and action characteristics
that you are looking for. Part 6, the
pseudo-lamination process, will stiffen it up just a little, but some final
sanding in part 7 will bring it back to where you want it.
I do not use any measuring tools for this stage – I do
everything by feel. Experience has taught me what to look for when it comes to
rod action and flex characteristics, and I just go with my instincts. I am not even
sure that precise measurements would enable anyone to reproduce specific rod
actions with any degree of accuracy; unlike bamboo, there is just too much
variation in the wood characteristics to allow for accurate reproduction using
measurements. If you are just starting out, and need some sort of guidance, I
would recommend having a fly rod of the action you are trying to produce close
at hand, and use it to compare flex characteristics and action as you sand the
wood blank to taper.
The sanding process is similar to the Initial Sanding; a piece of sandpaper is folded
around the blank and worked back and forth as the blank is rotated. But unlike
the initial sanding, where the goal was to simply produce an even taper, here
you want to pay more attention to how the blank actually flexes. As you sand,
you need to be constantly testing the blank by pressing the tip down on the
ground and seeing/feeling how it flexes. A few casting strokes will also give
you a good idea of the rod action. Generally you will end up with a blank that
is relatively thin at the tip, evenly tapered into the middle section, and a
quick taper to a thicker butt section. A simple even taper all along the blank will
not produce a rod with even action or proper flex characteristics – the blank
needs to be heavier in the bottom half of the rod to have the backbone to make
a cast.
It is best to use 100 or 120 grit sandpaper for this work.
Coarser sandpaper will certainly speed up the job but you will be left with
deep scratches that will weaken the blank. In addition, slowing the sanding
process makes it less likely that you will over-sand a section, rendering the
blank useless. As you sand pay attention to how the blank flexes, and simply
sand more where you need more flex, and less where you need less flex.
Two key areas that will need a little extra attention are
the tip and the butt. The tip needs to have a good even flex with a tip fine
enough to accept a 6.5 or 6.0 tip guide (usually the largest sizes available).
The butt section needs to be heavy enough to provide backbone to the rod but
thin enough to fit into the wood insert of the reel seat (the bore of the cork
grip can usually be filed out to match the rod dimensions). I like to have a
few different sizes of tip guides, and the reel seat/grip assembly on hand to
ensure everything will fit together.
One final thing to be aware of is that even though the drying process may have resulted in an almost perfectly straight blank, the sanding process often releases tension as wood fibers are sanded away, resulting in some slight warping of the blank. This warping is unavoidable – and becomes a part of the character of each individual rod.
Once the rod has been sanded to the desired taper, it’s on
to the pseudo-lamination process.

What's Hatching on Stauffer Creek
This past
long weekend was a great opportunity to get out and enjoy a day on the water.
Temperatures were warm enough to stir things up but not so warm as to cause
excessive run-off (at least not where I was). The trout were active, the bugs
were active, and there was good fishing to be had. And yes, even the odd fish
rising.
Winter stonefly
hatches on Stauffer Creek are on again with both Utacapnia trava and Zapada
cinctipes emerging in reasonable numbers. These are the first two stonefly species
to emerge on most central Alberta trout streams and although they look very similar,
and can be imitated with the same fly patterns, they are easy to tell apart if you
look closely.
Utacapnia trava is in the family Capniidae and is characterized
(in part) by longer tails with more than 4 segments. On the winged females the
tails can be seen extending past the wing tips. The wings are rather plain
looking and other than venation, they lack any distinctive pattern. The males
will also have long tails but they have reduced wings and are often mistaken
for nymphs crawling on the snow.

Zapada cinctipes, in the family Nemouridae, have
short stubby tails that are hidden by the wings – both males and females have
fully developed wings. The wings of both sexes exhibit some faint patterning.
If you have a small hand lens you may also see branched gill remnants in the ventral
neck region of both male and female adults.

Another
thing to watch for are adults that are light brown to tan in colour; these are
teneral adults that have just emerged – they will darken as their exoskeleton
hardens.

Things will
get more complicated in a few weeks as more winter stonefly species start to
emerge, but for now this at-a-glance identification on Stauffer Creek is
relatively reliable.
Temperatures
look to be a little cooler for the coming weekend but this could be more of a
blessing – with the heavy snow-pack, a slower melt should keep streams in
fishable condition.
