I've been doing resin casting for a couple of years now, and figured out pretty quickly that air bubbles are a serious problem. I mostly cast small parts to restore old toys, and a well-placed air bubble will completely ruin an otherwise perfect part. After doing some research, it became clear that I needed a pressure pot. There were a few commercially advertised units out there, but they were way too expensive, especially for a beginner that wasn't sure if making these tiny parts was even going to be worth the effort, let alone the costs for such a tool. But there are tons of youtube videos that will walk you through converting a harbor freight paint pot into a pressure pot for less that 200 bucks, so that's what I decided to do. It wasn't too hard, but did require purchasing a handful of fittings, swapping some things around on the lid, and cutting a wooden \"floor\" for the rounded bottom of the pot. I used it for a couple of years and it worked ok. The lid clamps were extremely sketchy, and it would never seal completely. It would usually bleed down overnight, mainly from the lid seal. I tried some of the fixes online, but never was able to get it to seal any better. Then one day while doing some casting a heard a \"clunk\" from it and about had a heart-attack. The cheap clamps had always scared me, and I was afraid the lid might just one day blow off catastrophically. Luckily that's not what happened, as only one of the pot metal clamps failed, and not all 4 at once. I survived it, but I was out a pressure pot and had orders to fill. Harbor freight doesn't carry replacement parts so I was left with either replacing the entire unit or finding something else. I actually stumbled across this pot while looking for replacement clamps for the HF one. I've never owned and Vevor tools before, but instantly liked the looks of the unit. mainly because of the beefy looking lid clamps. I checked the reviews, but at the time, there weren't any. I decided to drop the hamme
