gun setup

[isprayum]

I make my living with the sata hvlp's. I just picked up an old sharpe siphon feed, and im not familiar with this stuff at all. couple questions...

what pressure should it spray at for base, and for clear. this is considered a high pressure gun? just seems real mean.

what kind of air requirements do these things generally need? my idea here is that I can use one of these things at home with a smaller compressor than my satas need.

also seems like I should be holding it a lot further away from the panel.

I just need an old timer who loves these guns to school me here. I know I should just fill it and use it, but Im still trying to clean it.

thanks

What model number is the sharpe gun ?

[Warren]

I have a gaggle of them that I used to use on furniture. We could never get a wide enough fan on car stuff but I did run them pressure after lapping the tips and did some big furniture with good results. A big gun but way more comfortable than the last Satas. But then I ground and reshaped my Sata handles a while back.

Lke Phil I believe my Devilbiss 510's with 9000 air cap (I use 1.6 Nozzle) and I run them pressure is my favourite Conventional gun. I primered three vettes with that gun run pressure 10-15 lbs and 20 pounds air on a 25 foot hose and they came out very smooth.

It stacks up to my RP's but more overspray. I kind of think of it like speaker cabinets those old guns have more projection or longer focal point.

So what model do you have, I have a really old Sharpe primer gun when they used to use brass on the air caps, like it alot better than that aluminum junk on the 775's

the gun body says model 71, and the cup lid says 240 i believe. is it junk or what?

[Warren]

maybe Phil will.

If you want a good conventional for something and can get a Dev 502 or 510 and get that 9000 cap you will like it better than any Sharpe old Conventional. Again I found the fans were not wide unless I ran them pressure and personally I think they had way to many parts in them. The made it for the head to come off for cleaning I believe but I always found too many gaskets.

Also I tried one gun after sitting for years and the aluminum fluid adjustment stcrew had stuck. yeah I should have lubricated it but just another reason why aluminum sucks like when they used it in the air caps. Soft and it sticks.
