My local Range does not provide nor maintain wind flags on our 50m rimfire range, so every shooter is on their own for flags that have to be set up and taken down each session. I wanted a system that is light, portable, flags packable in a small volume, and low hassle for quick set up and take down.

We have a heated shooting house here on our 50m range and we can shoot all winter out the window ports, so changing snow depths and frozen ground are variables. They plow a walkway to the targets leaving snowbanks in random places. The ground is frozen hard for part of the year when a flag stand stake is not going to work. I needed a stand base that can sit on grass or snow, and is adjustable in height for the changing snow depth.

Nordic Marksman sells a premium wind flag set from Sichtkraft for IBU/ISSF standards. Made of steel and aluminum, will last a lifetime, reasonable cost, well worth it, and I would have bought it in a heartbeat (and I would figure out a way to make a snow base for the uprights)...BUT... My Range's rules do not allow metal stands mid-range. So no can do. :(

So, it was DIY time. This is what I came up with so far and have been using these for a couple of years:

Stand showing cantilever style flag. The stand is made of 1x2 softwood.

Stand tipped over, showing the base. The 1x2 is not fastened and can slide down inside like this to adjust for snow depth. Snow gets hip deep sometimes. Also packs away better in my truck without base attached.

Polyethylene tubing (1/4" ID, 3/8" OD) for the cantilever arm. That tubing wants to curl, so I chiseled a shallow V notch in the 1x2 so it would stay snug and sort of straight with the zip ties. The electrical tape was to prevent tube slipping out. In this photo I just noticed that the bottom zip tie must have moved up a bit. I should slide it down.

I used fishing tackle stainless wire for the cantilever arm.

The wire is 0.031" diam. Alone this was too light and it would blow out of the tube. So I added fishing leader sleeve clamps as weights that can spin freely (uncrimped). Brass swivels and split rings for the attachment. Red 1.5" ribbon from arts and craft store.

Top is doubled over for more bite for the brass grommet. I added clear packing tape to the windward edge to stiffen it as a blade, and it seems to work well to spin the flag longitudinally. This spin stabilizes the direction, minimizing random flapping, although it does flap somewhat, so its not perfect.

The flags and arms store compactly in a plastic sandwich-sized food container.

Performance: Fairly good for my first attempt. But some issues:

The thin wire and weights are very light, and in strong gusts these flags will sometimes blow out of the tube. The fishing tackle wire length available was only 8 inches, not really long enough. To improve the design, I would like to find longer stainless wire for the vertical arm of the cantilever so it stays in the tube better.
Also, that fishing tackle wire is so light the flags can sometimes be confusingly active. An improvement might be heavier gauge wire to dampen down the movement a tad. I might buy the heavier wire Sichtkraft cantilever arm that NM sells, but they are currently out of stock as I write this.

Meanwhile I am searching for stainless straight wire larger diameter than 0.031”.

I have some that are a garden stake with a hole drilled into the top.
A paper clip is opened to 90 degrees and a ribbon attached to the closed end of the paper clip.
1/2 inch pipe in the ground allows the stakes to be dropped in.
Surprisingly accurate and the price is right.
 
Well done, Biologist. Those are very nicely made and practical wind flags that will suit your purposes well. You are a model of industry -- at least in comparison to me.

I bought some Nordic Marksmen wind flags two years ago, but never summoned the determination to use them for the purposes of "reading" the wind. I've been discouraged because my range, which is small (100 yards maximum) and beside a lake, rarely has consistent winds from any one direction. The winds constantly switch and twitch, changing directions frequently.

I figured I might be doing well to know when the air is moving and when it's not. So I use a simple metal rod with surveyor's tape tied to it. This tells when the air is still or moving and if moving in what direction at that particular moment -- and at that particular place. I should have at least one more indicator two thirds of the way to the target, but one confuses me enough. I regularly see the indicator pointing in all directions when there is air movement while I'm preparing to shoot a single round. I figure reading the wind effectively must be one of the biggest challenges to master, once rifle and ammo are settled.

This year I've resolved to shoot only when conditions appear to be as calm as possible. Otherwise, I may be wasting ammo.

Below is what I've been using.

 
Hi Horseman2, that design sounds very easy to make, and definitely cheap to make. The pipe sections in the ground is a great idea that eliminates the base, which would work well in summer. If I had my own private range I would use that ground tube idea for sure. But at my local Range I don't think they would want those tubes, because they are always fixing something on the rimfire range, (backstops, berms, etc.), and sometimes they move the target stands to change alignment in the lanes, etc. So maybe an idea for the range managers for the future.

Thanks Grauhanen!
I made a set of three of those windflags. I usually use two of these placed at 1/3 and 2/3 the distance to the target. I used to use flagging tape on a stick or stand. But I found that without a freely rotating axle like the cantilever and wind vane type of flags have, that tied flagging tape definitely flaps and twitches more like you are saying. Also, the fishing snap swivel allows the flag to spin and stabilize and dampen the confusing flapping somewhat. If you add a fishing snap swivel on that flagging tape, and let the swivel split ring rotate freely around that wire, I bet you will see an improvement in less radical flapping.

It is very common that the two flags in my lane are doing different things, including pointing in different directions, or one in a lull and another pointing at an angle. They explain alot about what otherwise would appear as a weird flier. On a weird flier, looking at the flags immediately after the shot usually shows a gust or switch that happened just as I was pulling the trigger, but that I failed to recognize at the moment of trigger pull. Although it was the "wind's fault" (haha!), uh...no...ultimately it was my fault! (Damn! In rimfire there is no wind justice!).

Its amazing watching the POI result from the angle of wind hold based on what the flags are doing. Its very nerve racking in a match holding waayyy out into the 9, maybe into the 8, and hoping that bullet curves back into the 10 or the X....which is a great feeling when it happens. We also all know the stupid feeling when the bullet goes exactly where you were holding! Looking at the flags immediately after one of those mistakes usually shows the flag fell back in a lull which I failed to see a the moment of trigger pull.

I have to always use the flags when I shoot now, can't imagine not using them, even when it appears like a dead calm morning. Otherwise its wasting ammo like you say. Without wind flags I get "rimfire rage", or "rimfire depression", or "wind flag withdrawl syndrome", or "rimfire unknown wind anxiety disorder", etc., not knowing what the heck is happening with stupid fliers! :bangHead: (rimfire messes with the mind!).
 
FANNNNCY! looks good though. I suspect anything I got around to making would look much closer to what grauhanen is using, but my range has flags already.
 
Biologist , if you've got a friendly welder supply / welder in your area you can get stainless tig filler rod in .062 and .045 dia. Maybe even smaller but that's the finest I've encountered . 3 ft lengths so not worth buying a whole tube for your purpose but maybe some one would donate a rod or 2 to experiment with
 
Our local range has wooden stands and I just staple marking tape to the stands. Also I use dollar store bamboo poles that you get like 10 for $2 (the ones not used in my garden), with a bit of wire as a stand-off. The tape is about $4 at HomeDepot. (Double that at CrapTire)

Thanks Kewp! I will check that out!

That bamboo is a great idea! Already hollow so it can support the wire on top.
 
Have also used 5/8's" rebar with a spray can lid set on top with Ribbons staples to the outside edge.
Asked a millwright friend to build me a "Post Pounder" and that sets your post solidly with 5-10 whacks.
Not quite ball bearing smooth but rotates with the slightest breeze.
The reason I stopped using this system occurred when someone stole the rebar!
