- Vacuum pump able to achieve a minimum of 100 microns or 29 Hg at sea level. Better stabilized blanks will be produced at higher vacuum. (I strongly advise an electric rotary vane vacuum pump because it can require several hours of vacuum to completely evacuate the air blanks.) For an explanation of vacuum and stabilization, see this article.

The first step is to ensure that your material is clean and has a moisture level of less than 5% (or better yet, 0%). All wood, including wood you buy that has been kiln-dried, needs to be dried before stabilizing. No of how long it has been sitting, wood that has been left in your shop will always have an Equilibrium Moisture Content (EMC) because of the air’s humidity. In the majority of the nation, EMC is between 10 and 12 percent. Avoid using a moisture meter since they are inaccurate below 6 percent. Placing your blanks in your toaster oven at 220 F (104 C) for a minimum of 24 hours is the best way to ensure that they are as dry as possible after having already been air dried. The blanks should be taken out of the oven and put right away in a zip-top freezer bag or another airtight container to cool to room temperature. This is required because a piece of wood that is extremely dry and hot will begin to absorb moisture from the air as soon as it begins to cool down. When you add the Cactus Juice to hot blanks, it will promote early polymerization, which will result in total failure. NEVER dry green wood in an oven. Prior to drying in the oven, let all freshly cut wood air dry for a few months. Inaction will result in warping and cracking.
Avoid using oily woods like Cocobolo and Rosewood. The reason is that, in a vacuum, the wood’s oils will be sucked out and may contaminate the juice, preventing a good curing.
Place your blanks in the stabilizing chamber after that and add weight to them. Cactus Juice must be added to the stabilization chamber in the required quantity to completely cover the blanks with around 1-2″ (25–50 mm) of Juice. Ensure that your stabilizing chamber is situated in a safe, stable area. A vacuum chamber may explode if it experiences a violent shock, such hitting the ground.
If you wish to tint the wood, Cactus Juice can be colored. I’ve tried a lot of different colors and have found that Alumilite or Cactus Juice Stabilizing Dyes work the best for me. They are highly concentrated and generate pleasing, vibrant colors that blend and complement the Juice beautifully. Some colours, like Transtint, can be applied sparingly, but if you use too much, the Juice won’t cure as well. Make careful to apply more dye than you believe is necessary!
Place the chamber’s lid on top after the cactus juice has been introduced. To get the gasket to seal, you might need on apply a little pressure to the lid. When the vacuum first starts, a tremendous volume of air is drawn from the blanks, which causes the Juice to foam up significantly. The vacuum control valve should be fully opened before turning on the pump, and it should be progressively closed afterward to keep foam under control. Apply a thorough vacuum when the majority of the froth has dissipated.
It could take anything from 4-6 hours on the low end to 24+ hours on the high end to completely expel the air from your material, depending on the type of wood you are stabilizing and the vacuum pump you are using. The most typical, in my opinion, is 12+ hours. Tiny bubbles will continue to appear for MANY hours if your wood has even the slightest amount of moisture (24-36). I advise curing your wood as previously indicated. Once you notice very few bubbles emerging from the blanks, keep running the vacuum. Release the vacuum and stop your pump once all the air has been drawn out. If you’re using a rotary vane pump, it’s crucial not to turn it off while it’s creating vacuum. Your pump will experience early wear as a result.)
Give the blanks at least twice as long to soak without vacuum as you did with it. In many types of wood, a lengthier soak—up to a week—will produce greater results. Keep in mind that the majority of resin uptake happens AFTER the vacuum is released. Some wood species, like walnut and redwood, benefit from a prolonged soak. I typically let these soak for a week.
After the blanks soak in the resin, take them out. Allow the blanks to drain of any extra cactus juice. It is a good idea to carefully wrap each blank in foil if you plan to cure many blanks at once to prevent them from congealing into one solid mass while the Juice cures. Rolling out a 2′ (60 cm) strip of foil and starting at one end, rolling the first blank in the foil until it is coated, is a simple technique to accomplish this. Next, place the second blank next to the first, and then rewrap the entire thing. Once all of the blanks are covered, add the third and then continue. You are now prepared for the oven after folding the ends over.
If you can fit the blanks in without them touching one other, you can also cure them without covering them in foil. Juice can be kept in the wood without foil, which is not necessary. In order to stack multiple blanks in your oven at once and to limit the mess (part of the Juice may flow out when heated), it is there. Just keep in mind that if you stack blanks together or allow them to touch without foil, they will harden into a block that needs to be cut apart. Make sure to use a drip pan to catch any bleed out if you cure without foil. It is strongly advised against using foil when stabilizing objects that will later be cast in Alumilite so that the edges will remain free of dried cactus juice.
Now, preheat the oven to 190–200 F and lay the blanks inside (87-93 C). Make careful you use an oven thermometer to verify the toaster oven’s actual temperature. Toaster oven dials are infamously unreliable. The Juice won’t be harmed by being too hot, but it will “leak” out of the blank more frequently before it cures. For the Juice to cure, the blank’s interior temperature must reach 190–200 F (87–93 C) for at least 10 minutes. For the normal pen blank, this typically takes one to one and a half hours, although it can take longer for thicker material. Even lengthier time in the oven is not harmful, but if the blanks are not fully cured when you remove them and allow them to cool, putting them back in the oven will not result in a full cure. It is essential to be cautious and give them a lengthier cure until you have a better understanding of the procedure. Open the oven door and check the blanks for any cured Cactus Juice on them or in your drip pan to see if they are cured. Remove the blanks if you wrapped the items in foil, then peel the foil back. The blanks are finished if there is any cured cactus juice visible. Check again after letting them cure for another batch if you don’t notice any cured cactus juice.
When the blanks have finished drying, take them out of the oven while wearing gloves and remove the foil. The blanks must be allowed to cool to room temperature. After the blanks have cooled, you may either clean them up with a saw or scrape off the resin that has leaked out of them. Although it is not necessary, this step will enable you to see the final blanks more clearly and decide how you want to utilize them. An excellent alternative is a belt sander.
Pour the extra cactus juice from the chamber after the stabilization procedure is complete and preserve it for later use. I use quart HDPE plastic paint mixing cups with lids, which you can purchase at your neighborhood home improvement store in the paint aisle. Use PET plastic soda bottles instead of glass jars, which are optically clear plastic. It may eventually get better on its own. Since cactus juice does not evaporate, an airtight lid is not required. Simply clean the chamber with dish soap, water, and a towel after removing the extra juice. Before using it again, make sure it has thoroughly dried.
How is cactus juice activated?
Making your cactus juice active Shake vigorously before adding ingredients to jug. In order to guarantee appropriate mixing, shake the jug firmly. If the particles don’t dissolve, let them sit for a few hours and then shake them again.
How long does it take cactus juice to heal?
Heat curing of cactus juice occurs between 80°C and 96°C (177o F -205o F ). When the resin within the blank reaches 90° C for 6–8 minutes, Cactus Juice cures. The traditional small shop method for curing is to heat the product in a countertop toaster oven for 10 minutes or more, or until the interior blank temperature reaches the cure temperature. For a normal small run of 10 pen blanks, this usually takes 1 to 1.5 hours. Longer processing periods may be necessary to reach the necessary cure temperature when processing blanks with high cross section areas or bigger batches of blanks.
The highest grade monomers are used in the formulation of Cactus Juice to extend the polymer’s service functioning range. It is advised to use Cactus Juice continuously between -65°C and 189°C (372oF).
Under ideal storage circumstances, activated cactus juice will have a shelf life of roughly 12 months. The resin needs to be kept in its original container and out of the sun and other UV light sources. It’s important to keep storage temps below 29°C (85oF). It is advised to keep items in a refrigerator.
ALL CHEMISTRIES NEED TO BE HANDLED WITH CAUTION! Using well accepted procedures for handling non-toxic industrial chemicals, cactus juice resin can be handled safely. It is advisable to use rubber gloves when handling liquid cactus juice. If skin contact does occur, keep it to a minimum and wash thoroughly with water and mild soap. Consult a doctor if dermatitis develops, and stay away from the exposure. Utilize safety eyewear to protect your eyes from unintentional contact. If you should accidentally come into touch with your eyes, immediately flush them out with lots of clean water and get any necessary medical assistance.
Because cured cactus juice is innocuous, it can be thrown out with other industrial waste. Prior to disposal, uncured resin should be cured. Biodegradable resin is present in wash water effluent in solution.
Can cactus juice resin be recycled?
brand-new formula! Almost no foaming, at least 15% reduced bleedout, and pure water now! the same excellent cured qualities as the prior variant, at the same cure temperature and vacuum duration. This is merely a revised formula, not a totally new one. This variation will blend seamlessly with your current Cactus Juice.
A premium, professional-grade, heat-cured glue called Cactus Juice Stabilizing Resin is used to impregnate porous materials like wood to make them tougher, more resistant to moisture, and to add intrinsic color using dyes. The majority of woods retain their natural color after using Cactus Juice, which is simple to use. It is not solvent-based and is reusable again and over.

ONCE ACTIVATED, CACTUS JUICE MUST BE MAINTAINED AT OR BELOW 85 F (29 C) AT ALL TIMES. When in use, KEEP VACUUM PUMP AT LEAST 5′ AWAY FROM CHAMBER. A RAPID HARDENING MAY OCCUR IF TEMPERATURES ARE NOT MAINTAINED BELOW 85 F (29 C). Even when the shop is below this temperature, vacuum pumps can still easily contribute heat because they operate at high temperatures.
What occurs when cactus juice is consumed?
You may have heard that if you ever become stranded and dehydrated in the desert, a cactus may provide you with water. Although it seems like a good survival tip to keep on hand, is it really that simple? It transpires that a cactus is not essentially a freshwater basin covered in spines. In a dry environment full of thirsty creatures, such a plant would not survive for very long. In addition to their frightening spines, most cactus species further guard their spongy flesh with acids and powerful alkaloids since water is a very valuable resource in a desert. Most people find these substances to be too bitter to tolerate, and ingesting them puts a strain on the kidneys. Some cactus species’ meat can also result in temporary paralysis, vomiting, and diarrhea—none of which are helpful for your survival in a crisis. The prickly pear and one species of barrel cactus, the fishhook barrel, stand out as prominent outliers to this norm (Ferocactus wislizeni). While both of these plants are fairly unpleasant to consume raw, they contain fewer harmful compounds and could provide some hydration in an emergency. Better options include cactus fruits, however many are unpleasant to eat raw.
*Of course, all of this assumes that you are stranded in a desert in the New World with real cacti. Members of the Euphorbiaceae family, which resemble cactus plants, are poisonous and can be found in the deserts of Madagascar and southern Africa. If this plant’s milky sap gets in your eyes, it can permanently blind you and burn your skin and mucous membranes. Do not attempt to consume those.
Christopher Columbus claimed to have seen mermaids off the coast of what is now the Dominican Republic; however, they were manatees, and he described them as “not half as beautiful as how they were drawn.”
