Build a Pot Stand

 

Pot stands are important if you have a simple pop can alcohol stove that doesn't have a stand built in, and may also be used to supplement or replace heavier and less stable pot supports on commercially manufactured stoves.  The ideal stand for you depends on the size of your pot, personal preference and/or supplies on hand.

WindScreen-PotStand Combo

 

 

One popular theme is to combine a potstand with a windscreen designed specifically for your pot and stove setup.  The advantage being that you have a single lightweight unit that insulates and securely cradles your pot.  The windscreen can be made from aluminum roof flashing, cutouts from a thin aluminum bake pan, or just about any type of thin metal sheet (shim stock, heavy hobby foil, drink can sidewalls, etc.).  Some backpackers use stainless steel shim or titanium foil to make durable and heat resistant pot stands and can double as wood stoves.

 


Step 1 Windscreen Trimming

 

The real first step in building a windscreen-potstand is to read through the rest of this page and determine exactly what type of design you would like to construct.  After you have settled on a design, you can make a prototype out of paper extra foil and see how well this fits around your pot and stove and how well it packs.

 

Most designs fit around the pot in a similar manner and can be trimmed to size using the simple diagrams below (the folded and cone shaped versions are obvious exceptions).  First, measure the outside diameter of the pot you wish to use, keeping in mind that the top rim might be larger than the rest of the pot.  You may want to just measure the inner diameter of the pot if there is a large lip and your windscreen isn't going all the way to the top of your pot.

 

Add 1-2 cm (1/4 to 3/4 of an inch) to the diameter of your pot to allow for some space around your pot (necessary for carbon dioxide ventilation).

 

Multiply the diameter of your pot stand by 3.14 (Pi) and add 7.5 cm or about 3 inches for your locking tabs (if using the double folded locking ends).  This will be the overal length your your windscreen prior to folding.

 

Now determine the height of your windscreen.  Ideally, the windscreen should come up as high around the pot as possible, while still allowing room for handles, pot lifters, or to grab with protected hands.  Determine how much of your pot you would like to cover and add the height of your stove plus about 2.5cm for the flame.  If you wish to store your windscreen in your pot, your height will simply be the depth of you pot.

 

Mark your measurements on a piece of sheet metal (aluminum flashing or bake pan).  Taping graph paper on your sheet will help make square measurements and straight cuts a snap.

 

X = desired space between pot and windscreen (1-2cm)

Y = space between stove and pot (2.5-5cm)

 

If you are using aluminum flashing or some other sheet metal with a coating, you may wish to sand them down to remove any coating that will blacken, burn and become sticky after you fire up your stove.

 

The following pot stand calculator should help with designing.  The Fiddle Factor feature gives just a little bit of length to your screen to make up for any short cuts, folds, etc.

Step 2 Connecting the Ends

 

Backpackers often store their windscreen-potstands in their pot, around/inside a sleep pad, wrapped around their fuel bottle or rolled up for protection.  Because of this, it is helpful (if not required) to be able to disassemble your windscreen for storage.  Luckily there are several methods for making assembling and disassembling possible.

 

Your connecting technique will determine how much extra screen material you will need to overlap or lock your ends.  You should have read this prior to trimming your screen to help plan how much overlap you need - but if you have already made your cut, you should be fine since the above template allows for enough overlap for any of the following techniques.

Step 3 Pot Supports

 

There are several different methods of supporting you pot with your windscreen.  Here are a few examples:

 


 

 




 

The following Folded Windscreen Potstand Calculator should help make designing much easier.

Cut out three pieces of aluminum flashing 10cm by 6cm (or as tall as your stove height plus 2.5cm).  These will become the pieces that hold up your pot.

 

Note: Constructing tabs so that the bottom of each tab extends all the way to the ground will provide better support than the version shown.  In fact, for a little bit of extra weight, you can use sections of aluminum angle iron that extend to the base of the stand for dependable and durable support.

 

Mark and fold them as shown below.  You may have to lengthen or shorten these measurements depending on the size of your stove and pot.

 

Round off all corners and sand all edges smooth.

 

Now temporarily tape or krazy glue these tabs unto your main piece.  Rivets work best, but you can possibly use a heavy duty staples.

 

The T Template might help if you like templates.

 

Rivets can be trimmed with scissors and smoothed down with sandpaper and/or a file.

 

X = desired space between pot and windscreen (1-2cm)

Y = space between stove and pot (2.5-5cm)

 

If you like, you can add a threaded rivet or nut to your pot stand to store a backup screw for your pressurized jet stove.

Step 4 Final Touches

 


Ventilation

If you haven't done so already, tape a couple of lengths of graph paper to your stand to help keep your ventilation holes evenly spaced.  Now, punch out one to two rows of holes just above the bottom border to allow air to enter.  Some backpackers prefer to punch out holes only on one side of the stove so these openings can be pointed away from the wind.

 

X = desired space between pot and windscreen (1-2cm)

Y = space between stove and pot (2.5-5cm)

 

Remove the paper.

 

Clip the stand together and test your stove and pot.  Adjust or start over as required.

 

 


Smoothing

Round off all corners and use an SOS pad to smooth down all edges to prevent future cuts in the outback.

 

 


Lengthening Windscreens

You may want a taller windscreen than one that you can fit in your pot.  How can you do this?

 

Notable versions:

Other PotStand Versions

 

The goal is to find a lightweight method for your setup that supports your pot somewhere near 2.5-4cm or 1-1.5 inches (varies with setup) above your stove.

 

 


 

 

You may use rods, folds or other tricks to hold up your pot.  If you have a pot with an outside rim, you may be able to set this rim directly on the upper edge of the pot stand as shown above.

 

Titanium Goat Pot Stand in Wood Stove configuration

 

If you make your screen out of steel (stainless preferred) or titanium, you can make a screen that doubles as a wood/biomass stove.  Note how the commercial Titanium Goat stand above can use tent stakes to hold the pot up high and allow enough room inside the pot stand for a protected wood fire, and if the stakes are removed, the pot can sit much lower with the top of the stand snuggly wrapped around the underside of the pot's outer rim.

 

A cone shaped pot stand can be a bit tricky to build, but a little bit of math, a few careful measurements and a little bit of design planning - it becomes quite doable.  You will need to carefully measure your pots outer diameter and determine the base diameter and how high you want your stand to sit.  Halve your two diameter measurements and you have your R1, R2 and H numbers.

 

Frustum Potstand

 

With these numbers, you can calculate your T angle and your S1 and S2 lengths buy using the following formulas or this Cone/Frustum Windscreen Potstand Calculator.

 

R1 = Base Diameter / 2

R2 = Top Diameter / 2

S1 = R1 / ((R1-R2) / sqrt(H2 + [R1-R2]2)) = R2 x S2 / (R1 - R2) + S2
S2 = S1 - R2 / ((R1-R2) / sqrt(H2 + [R1-R2]2)) = sqrt(H2 + (R1-R2)2)

T = 360 x ((R1-R2) / sqrt(H2 + [R1-R2]2)) = 360 x (R1 - R2) / S2

Add to Top and Base lengths for overalap.

 

Use a piece of paper to draw out the shape of your cone and remember to add a little to the ends to allow for overlapping.  You can use a string, ruler, etc to measure out the S1 and (S1 - S2) lengths and use them to measure out the two arcs by pivoting them on the apex of the T angle.  Cut the paper sheet to size and see if it comes together and creates your desired shape.  If not, make your adjustments or start over with new measurements.

 

Once you are happy with your shape, you can use your paper trial as a template to cut out your actual pot stand.

Can-Pot Adapters

 

This allows you to set a Type I Can-Pot directly on your stove without the need of a pot stand.

Construction -

Simply cut out a rectangular piece of can sidewall or aluminum flashing to about the same length as your inner tube (the max length from a 12oz can sidewall would be ideal) and about 1-2mm wider.

 

Roll it up and stick it in your stove.

 

Test placing your Can-Pot on your stove and trim as necessary.

 

You can cut locking slits in your adapter to strengthen it but it must be perfectly set up and you'll end up with more sharp corners than you had before (unless you epoxy them down or round them off).  Epoxying it into a solid cylinder, punching three weep holes on the bottom edge, and/or sealing it to the stove with JB weld or RTV are also optional but not required.

 

The Type I Can-Pot made from a 12oz can may not fit tightly on a stove made of 6oz cans with the adapter above, but the adapter should hold the pot enough that it won't fall off while boiling.  Play with it until you are comfortable enough to take it backpacking, as it doesn't look like a good idea at first, but it does work.

 

 

If you wish to use a 24oz Type I Can-Pot (such as a large Heineken can) with a larger diameter bottom depression, you can simply cut out a disc (see templates) from aluminum flashing or steel shim and force/set it into the depression.   Another option is to cut out the bottom of a 3oz Spam Spread can and use it like the disc, which will fit perfectly.  Either option will create a flat surface that will allow you to use a sideburner stove made from 12oz and 6oz cans.  You may try to glue the adapter into the bottom of your Can-Pot if you like or just consider flipping the can over and making an inverted Type II Can-Pot instead.

 

If you want to get fancy, you can cut out the bottom of a 7oz Sterno can and fit it over the bottom of a Heineken can to make a nice flat surface. Or, you can use some pegs and a hammer to flatten out the bottom depression (it would be so much easier to cut the bottom of the can off and flip it over).

 


Can-Pot Stands

 

If you are using solid fuel tabs to cook with or wish to have something more stable and efficient than a Can-Pot Adapter, you can make a simple stand from a sheet of steel.  A suitable sheet can be found in hobby stores (Easy Solder Tin), specialty metal stores (0.005 to 0.010 steel or stainless shim stock) or from an empty denatured alcohol can sidewall.  Simply tape your template onto your sheet,  punch out the holes (you will need a heavy duty punch, arch punch or drill), cut it out, test fit (can bottoms very from can to can), drill the rivet holes (unless you opt to use the tabs), roll in the overlapping edge just a bit for athletics, and rivet shut.  Welded wire (don't use galvanized wire because of heavy metal poisoning) can be substituted for sheet metal but isn't as solid and will have many sharp edges that that should be filed down if you wish to avoid future cuts on you and/or your gear while out on the trail.

 

There are two different sized stands provided on the templates page.  The smaller one design is only suitable for use with Can-Pots made from 12oz and 8oz cans.  Due to its narrow diameter, you will be restricted to using solid fuel tabs, candles and alcohol stoves the size of tealights.  And if you get creative, you can convert your stand into a stove.

 

 

A stand with a larger diameter is required for use with 24oz Heineken and Fosters Can-Pots and also works well with ones made of 12oz and 8oz cans and regular pots.  These larger stands are wide enough to fit an alcohol topburner mini-stove made from 6oz cans (top and bottom section 20mm tall and inner wall 30mm) if you use short rivets, file them down or just use fold over tabs in lieu of rivets.  A nice fitting base for the large Can-Pot stand can be made from a bottom of 3oz can of cat food.

Note for Alcohol stove use - You may need more ventilation in your stand if you are using an alcohol stove.  Either "open" up your stand by removing metal from between some of the holes or use welded stainless wire (not galvanized).

 

Trimmed Stainless Steel Welded Wire (0.032") with 3 out of 4 wires removed

 

Welded wire isn't as resilient as sheet metal and you may want to soldering, weld or tie the ends together so that it doesn't collapse when a Can-Pot is placed on it.  You can also trim off a considerable percentage of weight by removing extra supports from the welded wire.  To avoid creating possibly hundreds of wire remnants with sharp points, instead of using wire snips, break the welds by grabbing the wire to be removed at the weld and twisting back and forth until the weld pops.

 

 

Since a great deal of heat is lost going out past the narrow bottom of the Can-Pot, a more efficient alcohol system might be constructed by decreasing the heat output and redirecting the flames to concentrate at the bottom center of the pot.  You might want to consider using a Tealight Stove.  Another option is to make a pressurized mini stove (top and bottom section 20mm tall with/without a 30mm inner wall) with its jets positioned around the inner ring of the stove angled in at 45°.  A primer pan made form a 3oz cat food can should allow a large Can-Pot stand and mini stove to fit snugly on it.  Twenty-four holes with a #71 drill puts out way too much heat.

Can-Pot Stoves

 

If you want to use the 24oz Heineken can or a Fosters can as a pot, you can make a stove designed specifically for that.

 

 

 

The main portion of this stove is made from a 3oz Hormel Spam Spread can.  It has been left mostly intact, with a fuel port hole cut in the bottom and jets drilled in the side.

 

Inner cylinder is 19mm wide.

 

28 holes 15mm from top of the stove drilled with #71 drill (needle size).

 

Heineken can bottoms fit perfectly around the rim and regular pots and pans can be placed on top of stove.

 

For details see - Zen Stove and Simplified Zen Stove.


 

Top portion of stove is a top from a Guinness can with the inner most circular crease scored and cut out.  Epoxied and centered is a circular ridge from the bottom of a Coke can (center depression cut out and everything below bottom of outside ridge cut away).  30mm tall.

 

Inner cylinder is 40mm wide

 

Bottom is an unstretched Pepsi can (fits snugly over top part) 20mm tall.

 

24 holes 15mm from top of can drilled with #57 drill (pushpin size).  Note - if you want more heat output, you may want to drill your holes just a bit more than 15mm from the top of your can.

 

The Guinness can is noticeably thicker than regular 12oz cans and should add weight and presumably strength to your stove (especially if you use the side wall for the inner chamber wall).

 

Heineken can bottoms fit perfectly around the rim and most 12oz can bottoms fit inside the rim.  Pots and pans can be placed on top of stove.

 


 

Very important - J-B weld is not a suitable epoxy for epoxying the top adapter and will burn off after the fist couple of uses.

 

Top portion is a rim from an Albertson's Root Beer can (rim has about the same dimensions as a Guinness top) with the innermost circular crease scored (from inside of can with a knife) and removed.  The side of can was scored at its highest point and removed.  This is epoxied to the top of the stove and carefully centered.

 

Stove made from two 6oz V-8 cans.  30mm top and 20mm bottom.  Bottom was stretched over two cans (a tool made of one unopened can with an empty can stretched over it).

 

Inner cylinder is 40mm wide.

 

The unnecessary stove base is a bottom from a Coke can (ridge cut off with stove slipped tightly in hole) epoxied to the side of stove.  This adds some stability, weight and bulk to the stove.

 

Like its big brother, Heineken can bottoms fit perfectly around the rim and most 12oz can bottoms fit inside the rim.  Pots and pans can be placed on top of stove.

 

When all is done, you should have a 1oz cook system (2oz if you use the 24oz Heineken can).
