Glenn,

It's $2,000.00 and change. That's one reason.

If you were a mold removal professional, spraying corrosive chemicals and ruining $200 dollar guns every two uses, the $2,800 bucks for this unit would pay for itself in the first month of jobs. Not so much for painting our toy airplanes.

There's a reason professional auto painters don't use airless systems.

Maybe Howard Rush uses one of these? I only say this because he's always talking about "squirting" and "tooting" paint on and I wondered how he did that... an airless like this would explain it.

Boy that is a fact...I can't imagine what I would use one for unless I needed to paint my house (and then I would call a house painter.) 

I bought a professional airless one time (a Binks industrial size) to apply dope to the blades of an experimental wind driven generator.  This was, at the time, the largest wind driven generator in the world and it was designed & built by a joint venture between So Cal Edison & Bendix Energy Division.  There were 3 blades each 94 feet long x 15 foot chord at the root x 4 foot chord at the tip, and each blade weighed 38,000 lbs.  They were built of maple wood with open bays ahead of & behind the spar, and I covered them with the Razorback STC'd covering process which is essentially fiberglass cloth with butyrate dope.  Spraying that much area with clear, silver, & white butyrate was too big a job to use the standard air spray guns.  The airless gun put out so much material that it was all I could do to move fast enough to stay up with the gun.  I used lots of thinner and retarder in the dope.

The finish was definitely nothing to write home about but it really wasn't too bad for what it was applied to.  It was better than I expected from the airless sprayer.

Bill, I'd love to see that machine. Do you have any pictures of the building process?

Hi Rusty,

I do have photos but I will have to dig them out of the archives (these were before the advent of digital photos.)  I will take a look for them & try to post them.

Don't break your back on my account, those old boxes of pictures can weigh a ton. They are fun to go through though. I've got a Rubbermaid box of pictures I can't pick up Lol.
