Replacing my HP-CS with ???
Posted by CNicoll on Wednesday, May 6, 2009 4:25 PM

My old Iawata HP-CS has finally given up the ghost after a lot of terrific use.  I'm thinking of just getting another one and keep going, but wanted to see what else you all are using out there that you really like.  Anybody use the PrecisionAire Master Treo XF Airbrush for example?

Thanks!!

75% of my builds are WWII 1/48 aircraft, Allied and German with camo scheme's etc

15% 1/72 versions of the above

10% 1/35-1/72 scale tanks

I can't help wondering what would make the HP-CS not worth repairing.  Is the main body worn, or is it a combination of other parts?  Could you elaborate please?

Thanks,

Don

Hi Don,

No matter how I clean it, or have others clean it, the trigger sticks and the airflow on and off is sluggish.  I release the trigger and it takes about 1/2 a second for the air to stop. The local dealer who cleaned it says the 'seat' and other parts are worn and is causing the sticking.  Does not make sense to me, but nobody seems to have the answer.  If you have any ideas, I'm all ears!

Thanks, Chris

Regdab or Medea Superlube on the air valve ( sparingly ) will fix ya right up.  HTH.

Sounds like you let paint back up into the airbrush and it got into the air valve assembly.

My advice? Disassemble the entire airbrush, let it soak in lacquer thinner overnight or put it into a ultrasonic cleaner and get all the paint out of areas they should not be in.

Chris,

I don't know how handy you are with taking it apart, but if you're going to trash it you've got nothing to lose.  I don't have one, so I can't give you any advice.  Anyway, Coast Airbrush would sell you all the parts in the trigger assembly for $36, including the trigger.  I can't imagine they would all be bad.  Coast really knows Iwatas, and if you e-mailed or called them they might be able to help.

I don't mean to try to talk you out of a new airbrush.  Heck, get one anyway.  It doesn't hurt to have a backup.

Don

I've had this thing completely stripped down to all the individual parts so I think I could almost build one from scratch.  Thanks for the suggestion, I appreciate you taking a look for me.

I'm sorry Chris, I think I hijacked your thread without meaning to.

Hopefully you'll get some responses to your original question.

OK, why do you think it needs replacing?

A new tip and needle should make it as good as new. It may need a new needle bearing as well.

Contact Dave Monnig at Coast Airbrush in Anaheim, CA and explain what is happening to him.

Dave knows airbrushes believe me!

Unless you've been shooting corrosives through this thing you shouldn't ever really wear one out. Your air trouble probably can be fixed with replacement of rings/seals. I REALLY abuse mine and it hasn't failed me yet. Yeah when it gets paint backed up into the trigger assembly is does get hard to control the airflow. But after a good cleaning and boring with the appropriate brushes it works like new.

The "seat" that is in the air side of the body might have some residue on it.  The valve has a soft rubber like material at the base to contour to the inlet, so if the seat was worn some the material should still seat onto the surface and stop the airflow. My guess is it is the valve itself that is giving you the trouble. You'll need to replace the rings/seals or the whole assembly.

Fix it. If you don't want to keep it, sell it to someone looking for parts. An airbrush should last a lifetime. Kinda like do I fix the cars fuel pump or trade it off for a new one. One is more economical than the other. Wink [;)]

Ok everybody, you've spurred me into giving it another shot!  Black Eye [B)] (just kidding)

I downloaded the exploded view drawings from one of the airbrush websites, I'm digging out my cleaning brushes and am going to give it another go.  Will let you know how it goes.  Will take me  few days to get it all together.

Thanks for the gentle pushes, hopefully I'll get it cleaned this time!

Cheers, 

Chris

Cool! Dave is one of the most knowledgable airbrush people in the country.....seriously! 

He may be young but he knows his stuff and is on a personal friend basis with most of the biggest names in the business. If he can't help you nobody can. Wink [;)]

My HP-CS does the same thing all the time. I put lube on the trigger and it's good for a bit.

 

I know I've had lacquer thinners wash through the entire brush. I wondered if that could have caused the seal to swell? It feels like it's sticking in the o-ring.

Yep, same problem I have.  I've taken it completely apart and cleaned it, but maybe not well enough. Going to give it one more go...
