Last night I looked at what needed to be done to get the air assist working on the Zing, went to Home Depot, got parts, came back, hooked almost everything up, looked in despair at two poorly labeled parts being different sized, went to Lowe’s this morning, and finishes hooking everything up.
- The “quiet” air compressor seems loud in a small concrete room. It also needs rubber isolation pads or something to keep it from vibrating against the floor. That may be sufficient to quiet it down a lot.
- The new fittings (a 1/4" quick disconnect plug, a 1/4->3/8 NPT adapter, a ball valve, a 1/4->3/8 NPT adapter, and a 1/4->3/8 barb adapter) are all hand-tight, and testing shows there are leaks. Someone with more experience, or time today (or both) should probably take it apart and do it up again properly (wrench tight, teflon tape if appropriate, etc).
The leaks make it squeal like a balloon with it’s mouth pulled tight when the ball valve is on. That, too, is loud. It also drains the compressor tank fairly fast, so it cycles often.
I did not cut anything this morning, but I did run my hand under the laser cutter rail, and the air assist seems fairly strong.
