Hey Gear heads

Any of you gear heads ever lap your needle to the nozzle? The thought occurred to me last night as I was cleaning that dang micro nozzle from my Neo...
 
Problem is getting the lapping compound totally out of the nozzle. But yes I have tried it just to see how it would work. It does do a great job at marrying the needle and nozzle , it was just apaint getting the compound out...
 
Did you notice any low air pressure performance gains from doing it?

Better response time on the trigger pull , A little crisper lines on detailing. But at low pressure not really a huge difference that I could see.
 
Would it really need the compound? since the needle is steel and the nozzle is brass a softer metal?

Just curious :)
 
wouldn't it be easy to go a little far and perhaps put a ridge in the needle? or would the nozzle just be polished away before that happens?
 
yeah, being that the nozzle is softer, youd wear it away before youd create a ridge. At least thats my thought...
 
Wouldn't a ridge on the needle alter the air flow and in doing so would change the spray pattern?

Inquisitive minds want to know :)
 
Having to much pressure on the nozzle will cause it to wear down faster, but a good needle will not get a ridge line due to the softness of the nozzle.
When I did mine I have it set up when the nozzle had hardly any force on it and was mainly going to see it I could make a matched set.
When you read about the Micron , It is suppose to have a matched head system , To me that means that the head and the needle are match at the factory. So being a gear head I figured I would give it a go . I did use a needle and nozzle that had given me problems off the Eclipse CS, Being I had a brand new set to go in if it did not work out. But that brand new set is still in the package cause so far (2.5 years now) the set I lapped is working great.
But not something I will suggest just anyone to go try . It is like polishing a needle if you get it right paint flows great if you screw it up well you get to buy a new needle.
