Just to follow up on my previous comments onusing a small air tank to drive
I have seen roofers and other tradesmans using tanks for small jobs. It is
quicker and handier than setting up a compressor on site. And I saw one guy
who put an inverter on his pickup and drove a compressor to fill his air
tanks. Again, this is only for small jobs.
And if you are just going to build some frames from time to time, there are
a lot of businesses in your neighborhood who have compressors. See if you
can find somebody who will fill up a tank for five bucks or so. If you
could find such an arrangement, it would be chaeper than buying a compressor
for a couple years or so.
Again, everything depends on your actual air usage. The hardness of the
wood, the length of the staple, the sharpness (quality) of the staple, etc.,
etc. How many frames will you build at one time, etc.
And hey, as an artist, you can paint your tank up to look like some kinda
space age accessory! All the kids will think you are cool.
