Hi all, im new to the whole resin casting and am looking into starting resin casting to set things in clear resin. I ordered a basic resin kit type thing off ebay to just have a quick go and see what i thought and immidiately noticed all the bubbles.
After looking into this i realised that the easiest way is to use a pressure pot , however after looking at these online i realised they are expensive for someone just starting out who may not even stick at this yet or even if so wouldnt not use it allot.
Anyway my dads a blacksmith and knows about forming metals and how to weld etc and is generally pretty nifty at making things. He thinks that we could just make one by making a pot from something (we would insure it was thick enough and strong enough to withstand the pressure) and making a removable lid that bolts on securely with a rubber seal around the edge. He thinks to then put the pressure in we could just drill the correct sized hole into the side and somehow attach and seal a valve in, the same time of valve as on bike tyres, then use an air compressor ( we already have) and the dial on that to add the correct pressure.
Sorry for the long explanation of the situation but didnt want to miss anything out.
Do you thinks this would work ok? As after looking at proper pressure pots they look rather complex compared to what he had in mind.
Thanks for any replies

Wyatt,
I would not be comfortable with the set up you are talking about. There are many stories from other wood workers about pots blowing the lids off or any other type pressure disasters. I would not trust a pieced together pot even if the welder is experienced; you have to consider the materials used and how they will react to the pressure. I purchased a painters pot from Harbor Freight. I removed the full tube from the lid and plugged a couple other ports to seal the pot. I added the appropriate gauges and air supply. There are several U-Tube videos for this. The cost was minimal and is designed for pressure. The pot has worked very well, hold the pressure nicely over night and is easy to work with.
Hope this helps; be safe which ever way you decide to go.

Wyatt,
I agree with Otha I have heard of and actually seen pictures of malfunctioning Pressure Pots that were purchased, not homemade being faulty. It is like a grenade going off throwing metal shards everywhere. There are a lot of reputable companies around who make affordable and safe pots, which ever way you choose please use all the safety devices available to you to ensure your safety.
Happy New Year!
Regards,
Carol

If you do go the home made route, please also include a pressure release valve and regulator. That way you can be sure you are at pressure you need for successful casting, and if for some reason that gets exceeded, your valve will go before you pot does, without removing something critical from you or your surroundings.
Harbor freight pots are inexpensive, there are great how to vids for setup, and it is only 100 bucks for the pot and extra parts. Worth the $ for something as irreplaceable as your personage.

I agree with what everyone else here said. Go to Harbor Freight use one of the super coupons it's usually like 20% or 25% off and you'll have to buy some fittings a slip connect Quick Connect for your air compressor. For about a hundred to $110 you can build yourself a really good pressure pot. As others have said go on YouTube and you can find some really good videos to show you how to do this. This is what I did. Good luck.
