Good info, thanks. Sounds like we'll be painting ;) It's a front door, some exposure but mostly shaded.

Thanks for the info. What about Waterlox on the fir, no stain? Would it still make it look blotchy? And if we did not like the look, can you paint over Waterlox?

We just got a new front door. We had planned to paint it, so got a paint grade fir. It looks pretty nice (no knots or blemishes really), so we were thinking we might just stain it. Does fir take...

I guess that explains why my gun came with its own "proprietary" viscosity cup, made of plastic. The Zahn ones I see online are made of stainless steel, come with a "cetificate of calibration" and...

Thanks for the info. I'll get some of the larger needles and try those with this oil pant.

Absolutely would love to see your viscosity chart. Thanks. Any idea where to find a Zahn cup online?

The Fuji needle sizes are:
#3 = 1mm
#4 = 1.4mm
#5 = 1.8mm
#6 = 2.2mm

Hmmm, ok. Their "air caps" come with needles also. I guess they change the cap a bit for each needle size too. Well, thanks for the help. I'll keep experimenting!

Got a reply from Fuji. The viscosity cup that comes with their system is not any of the standard varieties, it's just their version I guess.

And re the different viscosity numbers for different...

I will contact them to get more details. It's a 4-stage turbine system. I'll post here if I get anything interesting from them.

My gun (Fuji MM4) only mentions one set of viscosity numbers, different according to material. Eg, "primers 30-40", etc. No indication of numbers correlated to tip sizes. Also, I don't think it...

Not sure. I have noticed on some product's MSDS (data sheet) there is a viscosity number in units of "KU" I think, but not sure if you can translate that into "viscosity cup units". I just go by...

I have a #3 and #4 tip. Do you thin the material according to the viscosity guide in the instruction manual? The paint I'm working with seemed to require so much thinning to reach the viscosity...

Do any HVLP users out there use the viscosity cup? I have been experimenting with oil paints and some waterborne poly. The poly registered a fairly high viscosity with the cup that came with my...

I have the Fuji MM4, am a newbie. Am spraying oil based paint and primer. The Fuji comes with an air adjustment coupler piece that is attached between the hose and the gun. It has a little valve...

I think since you attached a sketchup file, and not an image, it will work differently. I was able to open it in sketchup. Looks nice!

Ah ha, good to know. Makes sense.

No confusion here! Thanks for the tips, I'll give them a try.

HVLP newbie here. Am spraying Sherwin Williams Waterborne Polyurethane (satin) on the insides of new kitchen cabinet drawers. The drawers are just baltic birch plywood. I have a couple of...
