Upload a close up picture of the threaded side of the airbrush. That can help decide if it is just a threaded hole (most airbrushes) or something different. The point of gravity feed is just that, the paint flows into the airflow using gravity, Pushing down on the trigger opens the air valve on the bottom of the airbrush, and pulling back on the trigger pulls the needle back, allowing paint to spray out the nozzle. typically there is not a seperate valve opening and closing where the cup threads in.
A side cup works in the same way as a top mounted cup, gravity feed right into the airflow, the only difference is the side cup clears your field of view when using larger cups.
Also did a quick search about your airbrush and over at britmodeller someone found out that some grex parts fit so the cups may fit as well. Here is the quote:
“Grex XN nozzles work with Olympos HP100b’s if that helps; I’ve got one of each. watch the seal in the body of the O as it will likely be rubber; Grex teflon seals also fit. hope this helps JD”
Here is a link to your airbrush parts list. The cup looks just like grex:
I will get you that picture as soon as I can. Thank you for the Grex info. I actually emailed that company to see if they knew of any of their cups that might fit.
You need a hose that has the right fittings at each end for both the brush and your compressor. That’s probably not too hard since it’s based on Iwata, but on the compressor side you need something that is interchangeable at the regulator fitting with other brushes/ hoses.
And pick up extra needles and tips because they are out of production.
No need to worry about the hose size. Olympos uses standaed 1/8" fittings. These are widely available. I would recommend a quick disconnect to make things easier. You can get a standard airbrush hose with 1/8" on airbrush side and on compresser side it will depend on your compressor, most airbrush compressors use 1/8" but if you are using a compressor meant for air tools then you will need 1/2" fittings found at all stores that sell air tools.
The nice thing with olympos is that it uses all standard sizes unlike paasche and badger and other makes.
Sometimes free isn’t worth the trouble unless you knew it wasn’t a “complete set”
By the time you spend all your money and the aggravation in finding missing parts, you could would have been better off buying a brand new AB. Hobby Lobby got some airbrushes and with a 40% coupon, it’s a great deal.
This style is a compression/friction fit cup similar to the way the cups are fitted to airbrushes at the bottom, siphon feed. The cup is tapered so that it stays on with friction. The cup you are looking for has a metal tube that comes out the side and has a collar that would press on and around the knured portion while the tube goes inside the hole.
These cups are harder to find since most went to the threaded style. Iwata still makes cups similar to this without the collar but it may still work. Heck a bendy straw would work if you could keep it from leaking. Basically you need a cup or elbow tube that will press fit in and not leak, perhaps with an oring.
This one may work, just use upside down and remove the straw:
Blick art stores carries the iwata line with many of the cups. Go to a store near you and try one out. Pour water in it and see if it leaks before buying it while at the store.
The people at Coast Airbrush are very knowledgeable about most brands. If you call them and explain what you are looking for, there is a good chance they will know if something currently available will fit. And, if there is, there is also a good chance they carry it.
