I provided the link for you. https://youtu.be/8Xfsfrjur08?si=vTHqsgBzWCRwLtJE&t=11 Here is the finished fly I do have a couple of suggestions for improvements on the tying technique. On a size 22 fly, a problem is the narrow hook gap which is further narrowed by the dubbing. I suggest using a 2XS (extra short) hook. The Daiichi 1640 is 2 XS and made of standard gauge wire. So a size 20 would be the length of a size 22 BUT it would be made of size 20 wire so for it's length of a size 22, the wire would be 2 XH (2 extra heavy wire). It is a strong hook and is less likely open up. Secondly, a parachute fly is NOT a dry fly. The hackle is ABOVE the fly body so the fly boy lies IN THE FILM. The parachute is actually a emerger pattern. Because the hackle on a parachute is above the body, the body actually rides lower and in the film. According to my friend and instructor Gary Borger, the author of Designing Trout Flies, the parachute is actually a stage 3 emerger pattern. https://www.garyborger.com/2016/09/09/parachute-flies-stage-3-emerger/ https://web.archive.org/web/20101230025309/http://www.flyfisherman.com/content/film-flies "TStage 3. The insect pulls its head out of the shuck, followed almost immediately by the legs. At this point it enters stage 3, which is matched perfectly by the universal emerger: a Parachute Adams (or other fly with an upright parachute post such as the Klinkhåmer). [See “The Klinkhåmer Special” in the Dec. 2006 issue for more details. The Editor.] All three of the surface-emerging insect groups look the same during this stage. That’s why the Parachute Adams is the world’s number 1 dry fly: it matches any mayfly, caddis, or midge in stage 3. Most fly fishers think of the Parachute Adams as an adult dun imitation, but in reality it is an emerger. In stage 3 the nymphal or pupal body is just under the film and the legs are spread out on the surface to support the body. The body sticks almost straight up, with the wings plastered tightly along the top of the thorax as they continue pulling up and out of the wing pads. Light reflecting off the upright body with the wings plastered tight along the top, gives the emerging insect a shining, light-colored look. Still not convinced? Toss a Parachute Adams in a glass of water and view its position." Way back in the 1980's on the Flyfish@ mailing list, there were discussions about the fact that the parachute fly is not an adult mayfly pattern. The horizontally wound parachute hackle is also different from the palmered hackle of the Catskill dry fly. Dry fly hackle is NOT straight. It has curve. There is a concave side (dull side) and a convex side (shiny side). One must decide whether to wind the hackle with the concave or convex side facing down. If the concave side faces down, the hackle tips curve down TOWARDS the water and the fly will ride higher than if the convex side faces down. I want my parachute flies to ride lower in the film and imitate an earlier or trapped in the film emerger so I wind the hackle convex (shiny) side down so the hackle tips curve up and away from the water. The fly then lies LOWER in the film as a trapped emerger does. I have discussed this in detail in this previous post from from 2018. http://www.flytyingforum.com/index.php?/topic/35398-choosing-hackle-size-for-parachute/&tab=comments#comment-725800

"Is that Uncle Fred?"

When I was an undergrad at Stanford University back in the 1960s, Hughes Aircraft Company (a defense, space, and technology company founded by Howard Hughes) hired me during summer break to program mainframe computers in both Fortran 4 and Basic. So I have been in computer technoolgy for a long time. ALL Hard drives whether internal or external will eventually fail. An automated backup system connected to an external hard drive like the Apple computer's Time Machine or a cloud backup system is the best. Time Machine even allows the user to recover files that were accidentally deleted. https://support.apple.com/en-us/HT201250 And if when you replace your computer with a new Mac, you can automatically configure and move all the files from the old computer to your new computer. Or from the time machine external hard drive to you new computer. Everything is automated. https://support.apple.com/guide/mac-help/back-up-files-mh35860/mac#:~:text=With Time Machine%2C you can,weekly backups of your files. My computer has an internal solid state drive so the data does not get "fragmented." So it boots up faster and accesses data instantaneously. Since there are no moving parts in a SSD, it rarely suffers a "disk crash." They are more expensive at first but are well worth it. https://www.techtarget.com/searchstorage/definition/SSD-solid-state-drive https://www.sciencedirect.com/topics/computer-science/disk-defragmenter#: If you have a standard hard drive you should defragment it so that your computer boots up faster and can access programs and data faster. It will also prolong the life of your hard drive. https://www.toptenreviews.com/best-disk-defragmenter-software

Do you have link on the Renzetti site that explains this function? I have a Renzetti Traveller and there is nothing in the vise instructions that came with the vise that mentions or explains how to go from one direction to both direction rotation. I have instruction sheets for both the 2000 and 2200 series Travellers. Do you instructions on how this is done?

The Renzetti traveller will have an O ring on it. It is blue on the image below. Does your vise have that O ring? Other "knock off" vises that look like a Renzetti Traveller like the Kingfisher may not have the O ring. https://www.amazon.com/Kingfisher-Fly-Fishing-Blackfoot-Rotary/dp/B0C2DFBJP4/

Looks like a good pattern

My favorite pattern for the Blue Damsel is the Gary Borger braided butt damsel pattern using Cortland braided butt mono for the body. Color the mono with blue art marker and use a black sharpie for the black stripes. I think you can adapt your pattern to use the wing as tied on the Boger pattern below. He uses hackle and ties it parachute style around a blue synthetic post and then fold the post over as in the pattern listed below. http://www.garyborger.com/flies-and-fly-tying/braided-butt-damsel/ You can buy the Cortland 50 LB braided butt material at Trident https://www.tridentflyfishing.com/cortland-braided-mono-looping-material.html

Those could double for a blue damsel fly as well.

Years ago, Colorado discovered that 12 of their 15 fish hatcheries were infected with Whirling Disease. Colorado depends on stocking to keep their trout fisheries functional and fishing license sale revenues high. Guess what they did? Instead of destroying the trout they decided to stock them in the fisheries that already had WD DESPITE evidence that this would increase the load of WD in the watershed and spread the disease to the trout that were still uninfected. ""Parasite dose strongly determines the severity of whirling disease, which generally increases with the number of triactinomyxons the fish encounters (Hoffman 1974; O’Grodnick 1979; Markiw 1991, 1992a, 1992b; Hedrick et al. 1999a; Thompson et al. 1999; Densmore et al. 2001; Ryce et al. 2001; Ryce et al. 2004; Ryce et al. 2005)." Subsequent to Colorado's stocking, researchers found that WD infection in the downstream brown trout population had increased. The solution for Virginia, besides closing and sterilizing the hatcheries, is the importation of DeSmet rainbow trout from Montana which are immune to WD. This resistant strain was found by Montana Fisheries biologist Dick Vincent, who is responsible for turning the Madison River from a stocked fishery to a healthy self sustaining trout fishery. http://missoulian.com/lifestyles/recreation/rainbow-rebound---in-madison-river-new-trout-species/article_a5585588-acbc-5528-a2f0-f24caea09f59.html "It's truly remarkable," said Vincent. "A decade ago, whirling disease had wiped out 90 percent of the Madison's rainbow trout. Today, we have a population that's highly resistant and bouncing back quite nicely." Vincent is recently retired from his longtime post of whirling disease coordinator at the Montana Department of Fish, Wildlife and Parks. Never in his wildest dreams did he imagine that before he stepped down he'd see Madison River rainbow populations at 70 percent of their historic numbers.... Vincent was an FWP biologist back in 1991 when he first noticed that the Madison's young rainbow trout seemed to be dying off. He scratched his head a bit, nursed some quiet suspicions, kept careful track of the numbers. But years passed, and it wasn't until 1994 when he finally put a name to the problem - whirling disease. That's what they called it down in Colorado, where rainbows and other salmonid fish were circling the evolutionary drain.... Rainbow trout are not native to Montana. They came from California, a century ago and more, sloshing along the rails in water-filled milk jugs. At the time, a rainbow was a rainbow was a rainbow, despite the fact that distinct sub-species came from distinct watersheds. One of those coastal watersheds - no one now knows which one - provided the rainbow trout that arrived at Wyoming's DeSmet Reservoir, out near Sheridan, back in the early 1890s. Eventually Wyoming's fishery biologists killed off the DeSmet strain, in favor of a rainbow easier to catch, but not before Dick Vincent got his hands on a few. In 1977, Vincent trucked a load of Wyoming's DeSmet rainbows into Montana's Willow Creek Reservoir, near the tiny town of Harrison. That was long before the disease, and Vincent just wanted some good sport fish for the lake. But the whirling disease parasite eventually arrived at the reservoir, too, "and it did wreak a bit of havoc, but not nearly as much as we expected." That's because 30 percent of those wild DeSmet rainbows tested naturally resistant to the parasite. Everywhere else - including the Madison - only 1 percent of fish showed any resistance; which is why, in some Colorado rivers, some 98 percent of rainbows have been wiped out by whirling disease. Today - what with the California roots lost to history and the Wyoming fish killed off - Montana remains the last known home of DeSmet rainbows. They persist only in Willow Creek Reservoir, and in a single high-mountain wilderness lake - and in both places they have proved highly resistant to whirling disease, killing the parasite before it burrows through the skin. And although he has no definite proof as yet, Vincent is convinced their genetic heritage survives in one other river - the Madison. Perhaps, he said, they arrived by way of Hebgen or Ennis lakes, where a few Harrison fish were later stocked. "Personally," he said, "I'm pretty sure some of those DeSmet fish escaped from Harrison and ended up in the Madison. Then evolution went to work, and selected out the ones that can handle the disease." At Willow Creek Reservoir, where a solid DeSmet population initially proved 30 percent resistant, many rainbows died. But those that survived passed their resistance on to their offspring, and now some 98 percent have resistance. Down in the Madison, where only a few escaped DeSmet fish are thought to have lived among other rainbows, just 1 percent of the fishery showed initial resistance. The fishery collapsed, with whirling disease claiming all but 10 percent of the river's rainbows. But again, with the presumed help of a few DeSmet genes, the survivors passed on their good fortune and now 95 percent test resistant. "They're very well recovered from the darkest depths of the whirling disease," Vincent said. "The Madison is a surprising success story." It is, he said, the only Western river known to have recovered on its own. Vincent has tried to track the genetic history of those DeSmet rainbows, hoping to unlock the clues of disease resistance, but historic records are incomplete at best. He's not sure where in California they came from, for instance, or even if they survive there today. "It's a real puzzle, actually." He's also not sure how the DeSmet rainbows will fare in the long run, as they obviously are not evolved for the particulars of the Madison. How will they deal with seasonal water level changes, for instance, or warm water flows? "That's one area we'll need to look at," he said. "Just who are these new Madison River rainbows? Because genetically, they sure aren't the same fish that were there 20 years ago. There's been a genetic bottleneck. Will evolution iron things out? I guess only time will tell." That's why he's still advising caution, before biologists rush out to stock Montana streams with Harrison's DeSmet fish. Down in Colorado, and in Utah, where whirling disease has hit so hard, they've already started introducing Harrison's fish in hopes of also introducing parasite resistance. In Montana, however, "it's not that bad, yet," Vincent said. "We know we have the stock, and we know it's not going anywhere, so let's not be hasty. Let's do some basic research before we go moving fish around willy-nilly." After all, he said, it was moving species around that got us into this mess in the first place. "The Madison is coming back," Vincent said. "Let's see how that turns out over time, before we take any drastic steps."

Yellowstone Angler Tippet Shootout shows that knot strength depends on the tippet material used and the X size of the tippet material used when different materials are compared. Some knots are are weaker or stronger than other knots depending on the tippet material and X size. The Davy is one of the weaker knots in this test. https://www.yellowstoneangler.com/gear-review/tippet-shootout/ Here's what they say about the Davy knot: "The Davy knot was developed for one purpose – speed. In fly fishing competitions, lost time means lost fish, and often lost competition. Once you practice this knot it can literally be tied in a few seconds. Once your muscle memory is trained, you can even tie the knot without looking at it, allowing you to watch for rise forms. It also uses up very little material. Like the Orvis knot, when you pull this tight there is less friction. The only problem we found with the Davy knot was its knot strength. Reportedly, it is supposed to test nearly 100% break strength. Our data revealed it breaking strengths to be reduced by as much as 40-50 percent. For example, Rio Fluoroflex 2X has a straight pull break strength of 11.19 pounds. After averaging 6 Davy Knot breaks (or slips), breaking strength was reduced to 5.32, which is roughly 52 percent weaker. Bottom line: This knot is super fast and wastes very little material, however it tested weaker than a wind knot. Unless you are in a competition where time is of the essence, (or fishing to 8 inch trout) it only makes sense to pick a stronger fly knot "

You can buy 3 new Renzetti Master Vises at that price.

^^^^ What he said. I also assume that the repair person has to drive his service truck to your home to do the job. If that is true, I think $75 is quite reasonable. If you have to take the appliance to his shop and leave it there, then it is expensive. So which is it?
