tower stand project

[Ron]

As I age (knocking on the door of 50) and as my Dad gets older (77 years young) and as I have been helping more and more new hunters get into the sport, comfort has been more of an issues to extend time on stand. I have several locations in funnels on farm land that would work well with an enclosed tower type blind since I have already had success year after year with ladder stands in those locations. Mainly I want to build this first one to offer my dad a little more comfort on stand. The blood thinners he is on make it hard for him to tolerate cold weather. He really like the late ML season and this ought to make him more apt to hunt.

I plan to build some tower type blinds but would like to make them dual purpose stands that work for both gun and bow hunting. I scanned the web for ideas and designs that are commercially available. I quickly learned that manufactured blinds are very expensive (from $700 to $1,500 and that’s just the blind without the wooden structure that gets it off the ground) So I set about designing my own.

My objectives were to have a stand that can be enclosed for really foul weather, that could seat 2 people comfortably, elevated at least 10 feet to the platform meaning a seated person’s eye level would be about 14 feet off the ground, has horizontal windows for gun hunting and lower, vertical windows for bowhunting.

I then used a CAD design software to model the stand. Here is one of the early versions. It does not yet have the roof or door designed but I have since worked out those details.



The stands will be built from treated lumber but I want to build a prototype out of regular pine to work out the bugs and make improvements. Here is enough lumber to build the entire stand with the exception of the plywood and window materials.



I priced this amount of treated lumber at Home Depot and its around $250 and includes

4) 4 x 4 x 10 long

48) 2 x 4 x 8 long

6) 2 x 6 x 8 long

7) 2 x 4 x 10 long

The design has to be 76 year old friendly which is why there are more rungs that are closer together on the ladder than need be for strapping young folks. The internals of the box are 41 by 64 by 75 tall.

Here are some pictures of the prototype during construction. (I have already begun making changes from the CAD model. )





The walls being framed up.



Here is a wall with the sheeting on and painted (I figured the inside of the blind should be dark like most pop-up blinds) The dotted lines indicate a potential location for bowhunting, vertical windows but I am reconsidering their locations at this point.



A few views of the framed up box.









I think I need to make the porch larger and change the swing of the door. I also plan to install safety rails around the porch.



As long as I have a black stand, I will have to (during the firearms season) use a black gun. I dont have an all black bow or I would have used it for the picture.



To be continued …………………….

[Ron]

Rolled roofing is exactly what I plan to use. My brother has a bunch of it and yes, there will be a little pitch to the roof.

[Ron]

I added a 2nd support under the outer corner of the porch and redid the bracing. I also added a hand rail around the porch. I think I am about finished with the prototype stand as far as improving the design and construction. I need to work out the window details now.

[Ron]

I plan to build as much in advance in my garage as possible (like the ladder, wall, roof, windows, etc as well as pre-making and then disassembling the main structure after marking the pieces for re-assembly. The real stands will require a few strong backs but I have sons and brothers that can help in the woods when the time comes. This low fidelity prototype was easy for me to build alone in my garage.

[Ron]

Here is a crude sketch of what I am kicking around for the upper sliding windows. Lower windows will most likely be removable panels or hinged.

My thought is to pre-make the window units and install them in their frames after the blind is up.

[Ron]

I was going to just cut slots in the treated wood frames and then rub wax into the slots and on the edge of the plexiglass.

[Ron]

So I have had inquires about what I plan to do with this prototype tower blind and is I would be willing to part with it. The answer is yes but you have to get past the helpers I had making it. Here is Joe guarding the stand. He wont let anybody near it. He is guarding it now with the rifle I posted earlier and has set up his own "occupy" camp.



He only lets his other friend Joe near the stand. Both are ex-military and have bad attitudes. I thought the photo of the rifle in the blind would have tipped some folks off since it has two triggers (the second one being for the grenade launcher)



Plus they have this huge guard dog named Roscoe patrolling the perimeter.



They are all jacked up on Soda in massive quantities.



If you haven’t figured it out by now, this is a 3/16 scale prototype model that I built to help me address all the design concerns ahead of time rather than after spending much $$$ on treated wood when I build the real stands. Here is one of my “Scale” 2 by 4’s on a real 2 by 4.



Here are the scale sized nails I used.


Here is Joe taking a break after helping test the stand.



The lumber I cut and stacked for that first photo was all cut on my table saw. The banding on that stack of 2 by 4’s is just a thin strip of black electrical tape I cut with a razor.

[Ron]

I began working on the full scale tower stand over the holidays. The one issue I did not address with the scale model was the windows, namely the design and how they would open. At first I thought sliding side by side would be a good option but I forever lose half the window. I didn’t want a hinged design that either swung in or out because of the motion and the issues with keeping them open at a time when a deer approaches so I am messing around with a vertical slider with a counter weight balance system which makes the window very easy to open and keeps it in the open position without having to secure the window.

The Plexiglas and wood frame is 15 inches by 42 inches and weighs about 5 pounds The window rides in tracks on each end and slides up but the weight of the window was a bit much for super easy opening so I used the type of counter weight system so many milk house doors had on the farm.

I have not yet removed the protective film on both sides of the window nor have I installed the felt sliders to quiet the window but I got a chance to play around with the design to see if this is the route I want to go. Here is a view from the inside. The handle to open the window is a coat hook I modified and turned upside down.



The sill and sash on the outside are made from treated lumber and painted. I installed the sill at quite an angle to ensure water run-off as I don’t want water to get into the bottom track of the window and then freeze.



In the widow itself I installed a weather shield sort of mini awing made of aluminum. It’s the angle piece used for suspended ceilings.



With the window open, you can see how it protects the bottom track from rain. On each vertical end, I installed a “P” shaped piece of adhesive backed weather stripping also to keep water out.



To further detour rain, I added a wood strip above the entire window and then used a piece of roofing material called a gutter apron only I used it upside down to act as an additional awing to keep rain out.





Here is a picture of the temporary rope I used to tie the window to the counter weight. After opening the window a few times and hearing the hard stop I installed a block of wood and a piece of sticky backed foam above the window to quiet the stop.



Here is a video of the window being opened. It takes very little effort to lift. The “Clunking” sound you hear at the top of the window opening is not the hard stop but rather the crude counter weight at the other end of the rope as it swings and hits the wall. For a better and quieter counter weight I envision a PCV tube with the right amount of weight (perhaps sand) with end caps on the PVC tube. That sand weighted PVC would slide inside a slightly larger piece of PVC tucked into the corner near the floor. This keeps the weight from being bumped or swinging and making noise.



It looks promising so far. I still need to work on making the windows quieter.

[Ron]

Since the sun and its UV rays as well as the grit carried in the wind as well as rain, snow and the risk of birds trying to fly through the blind only to smash into the Plexiglas are all negatives that are likely to occur during the 8 months this blind will sit idle every year, I have decided to install off-season shutters to protect the windows and further weatherproof the blind. The other reason in doing so is that it costs very little to provide this protection since the shutter is made from the scrap created by cutting the window opening. The small latches and hinges came to less than $6.00. In the following pictures, I have removed the aluminum awning made from the gutter apron that will be installed above the window. In prior pictures I held it in place with tape for the photo. The aluminum is too fragile for the rigors of transportation so it will be installed on-site once the blind is erected.

Here is the view from the outside with the shutter raised.





The shutter sits against the lip created by extending the window sash.





I installed a wooden handle to raise and lower the shutter as well as 2 latches to keep the shutter closed.








The handle has a deep finger groove to make it easy to grab and hold on while raising the shutter.





The view from the outside with the shutter lowered.





This seems like a good and low cost way to protect the windows.

[Ron]

I finally got some free time to work on the blind now that its warm enough. I got the remaining walls built and positioned them together for a fit-up and so I can start working on the rest of the shutters and sliding windows.

[Ron]

The box now has two coats of Behr Premium exterior paint and the off season shutters are installed. The shutters will protect the stand and especially the Plexiglas windows during the 9 months of the year the stand sits outside unused and exposed to the elements.



The view from inside. I have yet to install the sliding Plexiglas windows on the inside.



The door has a smaller window and the Plexiglas will not open like the windows on the walls. As such, I had to install a dead bolt on the outside to keep it closed in the off season



Here the shutters are down.



There is a self adhesive foam gasket all around the window opening that the shutter touches to make a weather tight seal. Now its time to build the roof.

How high up is this going to be when complete Ron?

The location for this is pretty flat and it will be placed on a high point so the floor will be about 8 feet in the air. The seated eye level will be about 12 feet off the ground.

[Ron]

With the box mostly done, I turned my attention to the roof. I was going to use a spreadable rubberized roof coating but last weekend I was up North cutting firewood and my brother told me about all the rubber roof material he had on hand so I am going that route.

The roof is made from 7/16 OSB and framed with 2x2's (except where the seam where the two sheets meet, there I used a 2 x 3 and caulked the joint before screwing the OSB down).

The roof overhangs the box by 8 inches all around.



Then I gave the exposed underside 2 coats of the same colored paint. The center portion (inside ceiling of the box) will be insulated)



Ready to apply the rolled roofing material.



The Rubber is thick (just over 1/16th inch and very stiff (and heavy)



Its been cold lately (its 33 F right now) so I will have to wait until I can set the roof out in the sun to warm it up enough to stretch and smooth out the rubber before I can attach it all around the edge.

[Ron]

After spending a few hours in the warm sunshine, the rubber roofing material was easy to smooth and flatten. The wooden strips around the perimeter help hold it in place.





Then I used clear silicone caulk all around the top where the rubber meets the wood. This roof should last a very long time.

[Ron]

Yes but not if the deer is real close, These windows and this blind are more for my 77 year old dad to use for gun hunting. The next blind will have more vertical windows suited for a bowhunter.

[Ron]

Yesterday I built the frame for the floor. Its made from treated 2 x 6 with joists on 16 inch centers. Then because I had lots of scrap ends, I filled in the joist spaces with additional blocking. Is it overkill?? You bet. I don’t want a floor that creeks and groans. I’m building it once so I want it too be strong rather than wish I would have when its too late to do anything about it.



The first layer of ½” OSB was screwed down after laying beads of construction adhesive on all the joists. Then I laid down more construction adhesive and another layer of ½ OSB



Now I have a floor that an inch thick that is both glued and screwed. Is it over kill?? You bet it is.

[Ron]

Good idea Mike, I plan to carpet the inside of the blind as well as using a pad under the carpet which will deaden the sounds a bit more but applying great stuff on the underside sounds like a good idea too.

[Ron]

The pad I plan to use is not a carpet pad made of open cell foam as you would use under carpet. What I have is leftover blue closed cell (Moisture proof) pad (very thin, about 1/16” of an inch) that was leftover from installing hardwood flooring in my house. But perhaps I should not attach it and do as you say and leave it lose and roll it up after the season. My problem is that I will never be the last person to use this blind (my guess is lots of people will use this blind) That means that I would have to leave a list of instructions for the last person to follow which means they wont follow them anyway.

I’ve moved the stand deck out to the back patio because I need the room to build the larger parts of the stand. I leveled it up because when I poured the back patio I used a lot of slope for good drainage. Eventually I will bring all the walls out here as well and give them a test run before shipping the stand to its permanent home. I would rather discover surprises in the shop than out in the woods.



I painted the exposed edges even though the door threshold will cover this area and the OSB on the door will protect it. I just figured it was better safe than sorry with melting snow.



Then I framed up both of the sides of the base and marked the pieces and disassembled them.



If you go all the way back to the beginning of this project you will see I had intended to use a ladder to get into the stand. Sine this stand will be used by hunters in their 80’s as well as little kids. I went back to the drawing board (literally) and designed a very easy to climb set of stairs. The coast and time went up a bit but will make for a better and safer climb.



I don’t know what it is about treated lumber but finding 2, 12 foot long 2 x 8’s meant sorting through a lot of warped and twisted junk to get two that were usable.



It was a fun rainy Sunday project. Its going to take more than a couple guy to raise and position this staircase. Its pretty heavy. The stair treads are 2 x 10 24 inches.







Now I need to get back to making all the sliding plexiglass windows for the rest of the blind.

Ron, Sounds like you shop at Menards. ;D ;D ;D

Home Depot is less than a mile away so I have been getting all my lumber from them. It seems I always get the fresh stuff. When you saw it, jucie flows in front of the blade. when you strike it with a hammer, you get spashed in the face. An 8 ft 2 x 4 seems to weigh 30 pounds. I wan t o coat the treated lumber but I would like it to be dry first but It doesnt seem to want to dry very well. If you set it in the sun and wind to dry, every piece warps and twists.

[Ron]

The stand has been on hold for several days as a family member has had some medical issues I have had to deal with on their behalf. I did have an opportunity to redesign the windows and how they will be constructed to simplify making them. Its a simple lap joint and a slot for the plexiglass. Soon I will be back to work on the stand but sometimes life gets in the way.

[Ron]

Pro-E and a bit of MS paint. I dont like to waste material do I tend to design and draw out my ideas to solve problems in ink before I cut wood.

[Ron]

Window construction Is under way. Waiting for coats of paint to dry is taking too much time in the chilly weather.





In the meantime, I decided to add a little pitch to the roof to make sure the rain and snow are pitched away from the side with the stairs and the door. I ripped a couple wedges that fade from 1 ½ thick to zero thick. Then I cut some ports in between the bays to act as air vents. Then I covered them with aluminum mesh sheet to keep bats and wasps out. I will put a inlet air vent in the bottom of one of the walls. This way, when the stand is sealed up over the summer and its 100+ degrees outside, the stand will be able to breath a bit.









While waiting for the windows to dry I am making the tracks that they will run in.

[Ron]

There is a blind Just off the interstate on I39 that pass by every time I make a trip North. It has an American flag and a satellite dish on it but I suspect the dish was attached simply as a conversation piece since there is no electricity anywhere near its location. It look pretty funny and I’m sure there are those that think the stand actually has satellite TV in it.

After talking to others who have box stands and heading Mikes words, I was concerned about having this stand too well sealed up and don’t want to return to it in fall and find it filled with mold because of a lack of air flow/movement so I think the vents are a good idea because I think the summer heat and humidity are going to be far worse for this stands life than are wind, rain or snow.

[Ron]

The holes are pretty small (less than an 1/8 inch.) Its left over material from making my cold smoker sawdust burner.

[Ron]

All the windows are made and painted and the tracks installed. Time to start insulating and covering the inside walls with 1/4 inch OSB. I think I will paint the entire inside flat black. I also need to make the window counterweight system so no matter what position I want to lift the windows, they will stay up.

[Ron]

I started insulating the walls with ridged foam that 1.5 thick. I have some leftovers from the last meat smoker project so I didn’t need to purchase much additional foam.



After the insulation, I covered the wall with ¼ inch OSB.



Then gave the interior a spray coat of flat black.



For the bottom sections, I did the same except I had to create a smaller and uninsulated area for the window counter balance weights.



The ¼ thick OSB panel that covers the counter weight has to be removable should I need to service the weight. The other portions that never need to be removed are nailed in place.



I made a short video of the windows and the counterweight. The windows will stay open in any position without needing to prop them open. They slide well and are not too noisy



Because I have air vents at the top of the stand to vent off the hot air when the stand is sealed up during the off season, I needed an air inlet. I added a stainless steel mesh screen wrapped in an aluminum frame and then put a little rain guard above it. I placed it as close to the floor as I could. I think I have all the venting I need and hopefully the stand will have enough air flow to avoid getting moldy inside.



With the walls done I added a flip up shelf on the long wall and covered it with the same indoor/outdoor carpet I plan to use on the floor of the stand. Its hinged and can be lowered to lay flat against the wall when its not needed.





Lifting it and swinging the angle support down lowers the shelf.

[Ron]

Well the weather looks iffy but I rented a Uhaul trailer for the weekend and got some help lined up and plan to errect the tower stand on Saturday.

[Ron]

I got a call from my dad yesterday. He said its too wet to get the stand back to the location so I will postpone putting it up for a week.

[Ron]

After some dry weather and a forecast for a nice weekend I reserved a U-Haul trailer to get the stand up north to where it will be erected. Friday afternoon I was loaded and ready to go.



I enlisted the help of 2 of my brothers and a nephew. Was started at 8:00 on Sat morning. Building the stand didn’t leave a lot of time of picture taking but I did my best.



We flipped the stand over and set it on cement pads and leveled it.





Than anchored it in 4 locations with 3/16 cable and steel posts driven deep into the ground.





The pre-made stair case was the next addition.



Then it was time to attach the walls.





Putting up the last wall and the roof was a chore and I forgot to stop for pictures. It wasn’t until I finished the stair railing that I remembered to take more pictures. Here is the finished stand.









Here it is with the windows open and shutters down.



Here is the view looking North from the porch. There is a river that became a pond a few years ago when beavers dammed it up. You can see all the trees that died from being under water. The beaver problem is gone but the damage remains.



The view looking West. you can see 440 yards.



Looking North you can 1,000 yards to the farm.



Looking East to the river. I need to cut some shooting lanes.



When the stand was finished I attended a first communion celebration for my niece. Then I came back with my father to show him the completed stand. He liked it and it was easy to climb the staircase with his 77 year old knees.





I started the design of this stand back in Dec of last year (2011). It took 5 months to complete working on and off as time and weather would allow. It was a fun project that several people will be able to enjoy for years to come.
