How To Make A Pressure Pot For Casting

As promised, I will continue down the path of stabilizing and casting “worthless” wood by explaining how I build my pressure cooker and accessories. If you missed the previous post where I explained How to Create a Vacuum Chamber, you might want to start there. If you’re confused as to why a pressure cooker is needed, the main idea is that while molding harder materials like turpentine, you can pressurize and contract the air bubbles. The great thing about this process is that after the resin cures, the air bubbles remain so small that they are barely visible. As with most projects, watch the VIDEO! Please SIGN UP if you haven’t already. Before I get started, I’d like to share a few projects I’ve done recently with composite blanks made using this process. If you haven’t seen the Make a Hybrid Marking Knife article/video, it should definitely be on your next list.
SafetyThere are a few articles online that try to steer people away from Harbor Freight pressures but I feel that as long as you stay within the recommended pressure range and use safety gear, you should be fine. HOWEVER. YOU are responsible for your safety so don’t do something you don’t feel comfortable with topqa.info Pot Warning article: ResinAddict & PenTurnersMany people on the PenTurners site say the quality of the HF Pots is very likely and I agree. If you look at the pictures of the threads you will see some solder on one of the threads. I tried to clean it but it ended up damaging one of my adapters and I ended up exchanging it for another that I thoroughly tested before leaving the store. In the shopping list below, I provide an alternative link to an air-to-port container that has a higher pressure rating and appears to be made to a higher standard. pressure cooker and I won’t explain it all. I’ve seen many different setups and my results are a bit different from most adapters because I can and can’t find them.

Shopping list

I will try to put together a complete list and mark the items as required or optional. One thing to remember when buying adapters is that the thread used is the NTP (National Pipe Thread) standard. I would also like to mention that you don’t need to buy any of these online. Most Harbor Freight stores should have most if not all of the adapters you need and for a pretty good price.

• Harbor Freight Air Pressure Paint Bucket (Required)
  • Replacement paint tank (Slightly more money but looks better built.) (Optional)
• NTP cap 1/4
• NTP 1/4 Female / Female Ball Valve (Required)
• NTP 1/4″ Male Quick Coupler (Required but make sure it fits your compressor hose.)
• NTP reducer 3/8 Male to 1/4 Female (Required)
• Elbow 1/4 Female to Male (Optional)
• Teflon Thread Tape (Required)
• HDPE Sheet (Optional)

Meeting

As I said before, there are quite a few ways to assemble your pressure cooker and I won’t go into all of them. The best and simplest setup I’ve seen is the one Zack Higgins did, and I’ll provide a link below in the build reference. The general idea is to remove everything that comes with the paint pot other than the air diffuser on the inside of the air intake. Then install the provided reducer and safety relief valve to the outlet while fitting the regulator on the inlet. You’ll want to cover the right side of the pressure regulator, mount the pressure gauge on the top, and the compressor hook on the top. The next time you’ve used Teflon tape on every thread, assembly is complete.

Set up for the first time

Before connecting the compressor for the first time, there are a few things you will want to do. The first thing is to sneak into the house, get some kerosene and apply a patch around the rubber gasket on the cap. This will help get a proper seal so you may want to keep it around and apply it whenever the pressure cooker is in use.Next, you will need to set up the pressure regulator and make sure the relief valve is set to the proper pressure. I recommend reducing the pressure regulator on your compressor during the initial run to below the maximum safe pressure of the paint pot. (Make sure you don’t leave it there after setting, or it will slow down the time it takes the pot to come up to pressure.)

Pressure regulator

Getting regular dial pressure is pretty easy. Turn it to the left and the maximum allowable pressure drops. A little twist to the right and the allowable pressure increases. Before plugging anything in, you can rotate it to the left a few turns and then slowly bring it up until you reach maximum pressure. (I set mine to around 55 PSI.) You also need to remember to reset your compressor regulator at this point to make sure the pressure vessel regulator isn’t set too high.

Safety release valve

To adjust the relief valve safely, there is a small plate that goes around the spring-loaded latch that you can pull out to relieve pressure. In general, you can stick a small flat-head screwdriver or your fingernail down there and rotate the disc left and right. Moving this plate is actually tightening a spring underneath to regulate the pressure the valve will activate. While you’re adjusting the boost pressure up to your optimal operating pressure, chances are the safety relief valve will come into play, which may startle you because it’s huge. If this is the case, turn the disc to the right slightly until the valve closes. If it won’t turn off, that means it’s set to high and you’ll want to set your pressure to the active PSI and reduce the valve’s trigger pressure until it turns off and then back on. just a minute.

The first is the mold tray to help insert the mold into the pot, and the second is the molds.

Pressure cooker mold holder

There are two good reasons to make a pressure cooker holder. The biggest reason is because the bottom of the pot is concave, so it is difficult to put the mold down and completely flat. The second is to add some flexibility to the molds you are using and gives you the option of casting multiple samples simultaneously. I made mine with an adjustable holder in the form of multiple screw holes in case I wanted to pressurize two castings at once.I built my mold rack in no time with my Circle Cut Jigsaw. A few quick circles and a handle are all that is needed for a basic stand.

Mold

To make any kind of molding, you will need a mold or a template to pour the plastic into. I’ve seen many people use melamine but have heard enough horror stories to keep me away, unless it’s a one-time transaction. I love using HDPE as my mold material, which is why you’ll find it on the shopping list above. Not much stick to it and not very expensive either. I won’t go into the details of mold making because depending on the type of drum you want to cast your mold will be different.However, if you’re interested in making a pen hybrid, check out this very detailed PDF tutorial by Curtis at topqa.info.
