RE: [Chevelle-list] deVilbliss type JGA-502(good?)

The setup is really for lacquers and acrylic enamels. The size of the fluid tip is 1.8mm. The needle and fluid tip should be changed to at least a 1.6mm tip to be used with the newer basecoat clearcoat materials. The air cap would work, but there are newer more efficient air caps, such as the 9000, available. The cost to change the gun to the smaller fluid tip, needle and air cap would probably make looking into a newer gun advisable.   Don’t get me wrong, it’s an excellent gun and it would work with the newer medium solids clears and basecoat systems, just not as good as a gun with the proper setup. The newer products need to be atomized better than the older lacquers and acrylic enamels so a smaller fluid tip / needle / air cap combo restricts fluid flow more precisely than screwing in the knob that controls the needle movement.   By the way, it’s not an HVLP. Some areas require the use of HVLP equipment but the “paint police” have a hell of a time enforcing that one.   Bill Vander Werf     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Thursday, November 06, 2003 8:37 PM To: [EMAIL PROTECTED] Subject: Re: [Chevelle-list] deVilbliss type JGA-502(good?)   It has 30 stamped on the cap and after unscrewing the cap theres a number stamped on a dia that the needle shuts off in # AV-15-EX (inner cap?) I cant seem to unscrew the innner cap that this number is stamped on to reveal the tip size. Anougther question on the cap of the bowl it says open & drip free ( whats that for) looks like a vent. Also I thought you had to shoot with a HVLP gun these days. Is this a HVLP?

The only problem you may run into is that most of them came with rather large fluid tips and air caps by toady’s standards. The newer version of the same gun is the JGV.   Tell me the numbers stamped on the air cap and the fluid tip behind it and I can tell you what setup it has.   Bill Vander Werf
