Tool talk

Ill be replacing my truck bed this spring. Want to clean up the frame and recoat it.

What am I looking at as far as air requirements?

Anything air powered the runs continuously needs CFM more than PSI. When I was building cars I had a big twin cylinder compressor the could supply a lot of air volume, mid 20s CFM if I remember correctly. Not all big compressors do. If your shopping look for one that can supply more CFM the better.

Good point.
I found out quickly that a pancake does not work well for painting.
Got a 50 gallon and painting worked much better.

Doesn't sound familiar but maybe.
Cach. This is a scaler. I'm sure you've used one, but maybe call it by another name. Works great for cleaning up rusty parts

Sorry I'm not sure of the exact requirements, but I know it uses A LOT of air. I've run it off a large 2 stage shop compressor. (80 gallon I'd guess). So air volume wasn't an issue for me.

You'll notice a big difference in the size air hose you use as well.
I have one of those 50' coil hoses that's great for pulling out to the cars to fill tires. But it has a small diameter so it doesn't work good with big air tools.

You want a toe? I can get you a toe.

Yep mark this one in the lessons learned the hard way column for me. Bought a craftsman oiless compressor to run my plasma cutter. Fast forward ten years and I haven't used the plasma cutter once and the compressor only runs my air tools 30 seconds at a time. Not to mention its loud as hell.

When I build my 80x100 shop there are a few things I will certainly error on the side of better to have and not need. Room air and electricity come to mind.

My big one was an 80gal, 2 cylinder, high CFM. The two things to look for are CFM and capacity in that order.

If your building your dream shop, go for a screw type compressor. Nice & quiet.

Yeah rotary screw is certainly on my list. Probably depends on what I find on Craigslist. If there is a deal on there that I can't pass up and meets my needs well that's just more money for a CNC machine. :)

If you ever get a CNC, I'll bring the brass and stainless billet to cut out putters!

A CNC would be nice, but massively expensive. I had a temporary job assignment running a big Mori Sekei lathe threading pipe. BOOOOORING. I looked forward to stopping every 20 pieces to measure with a micrometer.
A lack of adequate CFM can really slow down a project. I was modifying an intake manifold this last Summer with a die grinder and it took forever because I could only go about 30 seconds before pressure was too low.
