You can 'open up' the design of the supplied air helmets and rearrange for the relatively stationary work you do. You don't need a hard hat, so get rid of that. Mount the battery pack on the lathe or the wall nearby. Then all you have to do is wear a lightweight visor and hose, and on/off switch. Make sure the make up air coming into your system is clean. You can bring in clean air from several feet away if you like.
While this is not a professions for you (?), you might still consider spending $2,000 against your health, safety and comfort. If you work at turning 40 hrs a week, the cost is only a dollar an hour. Then you own it.
People regularly spend over $2K on the add for upgrade stereo in a car and end up listening to Golden Oldies....

I want to stay as close to the edge as I can without going over. Out on the edge you see all kinds of things you can't see from the center.
