If someone is looking to build something this size, but doesn’t want to spend 1300, there’s ways.
Use a normal recovery tank (mastercool 15#)
Scour the webz
I bought a “solvent tank” from ablaze awhile ago that was a 6*6 bottom with an ok lid for 110. I rigged it up as a collection pot. It’s 150 now, and you’d need to get a bigger collection bottom, but that’s only another 130 tops.
Now you need a material spool.
3*12 45
Caps 2x 40
Valves 2x 30
So, 100+150+130+45+40+30 = 495
Add another 100 for some hoses and extras, which is very generous, and you have a system ready to go for under 600. That’s all us stock items too.
If you’re really interested in building on a budget, you can, but you need to be ok with some sacrifices, and have to do the research.
In the end, if it’s for a personal setup, I can recommend this route. But if someone is looking to turn a buck off of it, you gotta ask if your time is worth all of that.
I always find it amusing the value people put on their life/wellbeing. A pressure tested $1,300 unit from a trusted forum member or a $700 roll of the dice using hydrocarbons. What’s the worst that can happen?
And regardless, people will still do it. Again, not trying to argue, but I’m not going to not give advice.
I trust a mastercool solvent tank over a something of unknown quality. If someone is set on saving as much as possible, even if the consensus is the opposite, I’ll still give what I think is the best advice, most safe advice.
If I was trying to set one up and I have say 1000 would that be sufficient for about 1 or 1/2 a lb at a time? My max budget would be like 1600 please help and advice welcomed
