I built this simple fully-adjustable bow sight out of scrap wood and plastic I had at home.  You can have as many sight points ("pins") as you like, and they can be very close together.  The sight is frameless and does not cover up any part of the animal or target. 

The sight is very simple, and hardly needs instructions once it's described:  It's just a rectangle of acrylic mounted in front of the riser, and the sight points are marked with a fine-tip wet- or dry-erase marker.   Took a lot longer to write up the instructable than to make it.

You can color-code for different users of the bow or for different arrows or for field points vs. broadheads.  You can put in sight points for all the targets in your club's field course, and even use one side of the acrylic for your permanent default sight points and the other side of the acrylic for wind-adjusted sight points.  You can write distances and other notes beside your sight points.  And all this at little to no cost depending on what you have in your scrap box.

NOTE: There is at least one potential safety issue, which is that perhaps if an arrow jumps or shatters and hits the sight it might ricochet at you.  Don't use crooked arrows and always test carbon arrows before use.  USE THE SIGHT AT YOUR OWN RISK.  If this is a worry to you, don't use the sight, or maybe use undercut plastic screws or a weak glue (e.g., hot melt) to attach the plastic sight to the plywood mount for a more controlled failure.

I designed the sight for a recurve (a 66" Samick Polaris, 26# @28"), but it might work for a compound, perhaps with some changes.  I'd love to hear if you got this working on a compound.

  • Piece of clear see-through plastic that's rigid enough not to bend noticeably in the wind when supported by one side and clear enough that you can easily see what you're shooting at through it.  I used 1/16" acrylic from some old Melissa and Doug toy boxes.  The exact dimensions depend on how much adjustment range you need for your bow.  My final sight is about 3.7 in x 2.6 in.  If you can't find any acrylic sheet you want to sacrifice, you can order acrylic or polycarbonate sheet from Amazon.
  • Piece of 3/8" - 3/4" plywood, big enough to cut about a 2 in x 4 in rectangle.  Better quality plywood will reduce warping and thus reduce the need to re-adjust the sight.  I used scrap 1/2" Baltic/Russian birch.
  • Either: Two #10-24 screws long enough to go through the plywood and anchor to the sight threads on the bow.  (If you don't have sight threads on the bow, you'll need to put in a threaded insert, or just use wood screws to mount directly to the riser.)  The screws I had were too long and I had to trim them. 
  • Or instead for greater safety: Hot-melt or other weak glue for semi-permanent attachment of plastic to wood.
  • Two small wood screws
  • Fine-tip dry- or wet-erase marker.  (Fine-tip dry-erase markers with a built-in eraser might be the best.)
  • Kleenex or paper towel
  • Optional: Different colored of markers for multiple users
  • Optional: Stickers instead of markers.
  • Optional: Wood finish, paint, camo fabric, etc.
  • Optional: Washers for the wood screws
  • Optional (if you want to get a better idea of placement and size): Toothpicks or wooden matches, masking tape and target.
  • Safety goggles
  • Metal ruler
  • Box cutters
  • Saw
  • Drill
  • Sand paper / flat file / sander

Step 1: Figure Out Size of the Sight's Window

You have two options. 

Option 1: Decide to make the sight window really big, but not so big it will get in the way of arrows and other equipment, and later cut it down to size once you've started using and found how much of the sight area you need. 

Option 2: Put masking tape on the inner side of the riser and sight along the edge of the masking tape to see how high up and how low down the marks for your closest and furthest expected shooting distances should be.  Tape up match sticks to sight along the ends of to see how far away from your riser (left of riser for a right-handed bow) the sight's window should go, as well as how high up it should go.  Add a good safety margin to take into account variation of conditions (arrows, points, wind, and maybe multiple users), plus about 20% to account for the fact that the sight is further away from the eye than the riser.  You can always trim the window down later.  Then add to the width the thickness of the plywood you will mount it on, plus the thickness of the bow from the sight mounting holes to the edge of the riser where you had the masking tape.

Whichever option you went for, you can now mark with masking tape how far up and down along the riser you want the sight's window to go.  Keep it out of the way of the arrows!
<p>Dude, this is a great idea. My bow is getting here in a few days, and I have been looking for an old school, simple pin sight for it with no luck. You have a great idea here, thank you for sharing. Here is a reticle that might work, if simplified a little bit withe less points. </p><p></p>
I used an old case of a cassette, works fine!
Nice bow! What is it?
66&quot; Samick Polaris. About $120 from Lancaster Archery.
An idea I just had is that a high quality transparency with a grid printed on it could be attached to one side of the sight for adjusting the points, because then one could see where in the grid the arrows are hitting.
Taking a second look at your ste-up, I can see some advantages to this that I don't have with the sights that I use pn my compound bows and the scopes on my cross bows. Seems like with this set up target aquisition, and sighting in on a deer in low light conditions will be much easier. I got busted by a buck some ten days ago. It was about two minutes before the end of legal shooting hours, lighting was low in the woods, I had a buck come in to me and I was using a crossbow with a scope. It was tough under the lighting conditions to get a good aim through that scope. Buck got to maybe 20 yards of me. I didn't want to take a front shot and was trying to get a decent quartering shot through that scope. He must have caught sight of me for he just spooked and blasted off. Not having my vision limited so much by a scope would have helped.
For low light conditions, you'd want somewhat better quality acrylic or polycarbonate sheet. Mine dims the image a little bit, but again it doesn't matter for my target shooting. Good quality polycarbonate, like in safety goggles, won't dim anything. <br> <br>One more possibility is to use fluorescent stickers on the sight, and then have a UV LED shining at it. (There will be glare issues if the LED emits visible light as well, though.)
Thanks. As for using things like UV LED lights on a clear sheet, I have the same problem with my illuminated scopes. Once low light conditions get low enough, the is too much glare inside the scope washing things out, even though I have it on the lowest setting. At this point I find it best to turn off the rheostat all together. I can still work with what I see of the cross hairs, and at 20 yards, if I put the target in the dead center of the scope, it should be decent shot. I'm thinking along the lines of fiber optic pins, or some glow in the dark stuff. Either dipping the pins in the glow stick material (it should glow for a good while, probably messy) or glow in the dark plastic (may not glow long enough and needs to be exposed to lots of light first.)
I have red dot finders in all three of my reflecting telescopes and with an added variable or fixed resistor, they work just fine no matter how dark it is outside. <br> <br>You could combine a UV LED with a Wood's Glass filter, and get no visible light, and then all that would light up would be the fluorescent sticker, with brightness you could vary with a resistor on the LED. <br> <br>But probably this would be overkill--I expect that a clearly made dot or circle on the scope would be visible, at least as long as it's not so dark you can't see the target either. <br> <br>You can try it and report back.
Wonder how this will work out when I'm after that 12 point buck. Certainly can see the problems with the sun and the plexiglass. Do you have a way to adjust for windage? How are your shot groupings working out?
If the plastic is clean and smooth, the sun should reflect according to the laws of reflection (incoming angle = outgoing angle). Since your eye is close to at right angles to the plastic, that will mean the sun will have to be pretty much behind you for it to show up in the plastic. If it's scratched up as mine is (years of use as the lid of a toy box), you will get additional reflections at other angles, but it's not an issue at our range, I think.<br><br>Moreover, the reflectiveness of transparent materials is smallest head-on, which reduces the problem somewhat.<br><br>By windage, I assume you mean left-right adjustment (azimuth, as we amateur astronomers call it). Just put a dot further left or further right for that. <br><br>My groupings aren't great (an understatement!), but I think it's because my form needs work rather than any sight issue. It was better last time I went out, but I'm down to two arrows which makes it hard to tell (I've got an order for a bunch more, but they are backordered).
i tried this a while back, the only problems i ran into was the sun would reflect of the plexi, sometimes blinding me, any suggestions on how to fix that? <br> <br>good instructable *thumbs up*
I would think blinding is only going to happen the sun is right at your back, fairly low down, namely when you're shooting westward near sunrise and eastward near sunset, and the angles just work out. It won't be a very strong reflection, because the angle of incidence of the light will be around 90 degrees, and reflectivity is minimized at that angle. <br> <br>One possibility would be to move one step left or one step right, if circumstances allow it, and then the issue should disappear. Or wear a hat that puts a shadow on the sight? <br> <br>Another option is to get an antireflective screen protector for some phone whose screen size matches the size of the sight. I search Amazon for antireflective protector and found lots of hits.
There is also anti-reflective acrylic for picture frames. Here are some available in retail quantities: http://123frame.net/noplgl.html <br> <br>It's not cheap, though one could buy a large sheet and that would last for many bows. <br> <br>Apparently, one needs to distinguish anti-glare from anti-reflective. I think the anti-glare ones are matte, and hence will blur the target. The anti-reflective might be better. <br> <br>Also, might be good to avoid the fatter sheets as it'll be harder to match up dots on front and back surfaces.
Nice instructable <br>That is a really nice wooden recurve <br>where did u get it?
LancasterArchery.com -- They not only have good prices but also very good customer service. <br> <br>The only imperfection of the Polaris is that it doesn't have a threaded hole for the clicker on the riser, so if you want a clicker, you need a stick-on. I don't have a clicker, but I have made a mirror-based draw check that can be stuck onto the sight, though I haven't yet tried it.
This is a VERY nice and usfull Instructable. thanks for sharing. <br>
I used to do some archery, and I can see how useful this little gadget would be.<br><br>Good idea.
