Thanks for the info and feedback. I ended up picking up a used Rigid 4.5 gallon portable on craigslist for $85.00, that says it puts out 4.9 SCFM. So far for the small cuts I’ve been doing, and learning/experimenting its worked fine, it kicks on after 10 seconds of cutting or so, but no issues yet. I talked to someone who had also connected two smaller compressors, with check valves going into a tee and said it worked well (noisy). I will probably pick up a 60 gallon stationary at home depot or lowes in the next 30 days, right now planning on home depot, just because I like their customer service better the lowes, mostly. Or if my small compressor set up continues to work for now, maybe I will save up a few more dollars and get an 80 gallon from somewhere.
Anyone have an opinion of lowes vs home depot? I’ve also seen some good reviews of the 80 gallon at harbor freight as well.
