I duct mine through a dryer hose into an enclosed, filtered 5 gallon bucket.

Do you have a picture of that?

Thanks,
Scott
There's a prototype for everything.
If you can't make it perfect, make it adjustable.
DCC is not plug-n-play.

This is the only one right at the moment.
The green 5  Gal. bucket lower right has two bent coat hangers that form a shelf about midway up/down that support a circular cut piece of furnace filter.
You can see the hose that goes into a hole cut in the lid from the outlet at the back of the fan.
The whole booth is made from Foam Core board with a plexi-glass window on top where the swing arm lamp shines through.

The spray booth worked really well last night. Now I just have to up my airbrush cleaning game. For solid colors and clear coats I think my dual action brush is overkill. I may pick up a cheap single action external mix for those jobs.

I just switched from my Paasche external mix  back to a Paasche dual-action internal mix.   I found that external mix worked fine for lacquers (e.g. Floquil), but not so much for my preferred paints - Tru-Color - due to paint buildup on the tip while spraying.   Yes, dual-action is overkill for just "painting", but I'd recommend an internal mix single-action.   See Peteski's notes on how to clean it!

I'm sorry Dave, I'm afraid I can't do that.

@nickelplate759 my experience is similar...  My trusty Paasche H (single action) works for the majority of my work.  I also have a Badger Patriot 105 for detail work, but it is very sensitive to tip dry.

This post brings us to the end of the Boardman switching shelf v1.  There are a few design obstacles that seem insurmountable at this point and i am feeling like a fresh start is in order.

When I original started building this layout I wanted to keep it small and limited to a small bit of my office space (1x8) That lead me to a switching shelf layout with no opportunity for roundy round.

I have since retrofitted a turnback loop and a turnback helix and expanded the layout to a footprint of 2.5 x 12.  This design gave me the option to let the trains run and a staging track, but with the helix and tight radius on the turn back loop along with the 2.5* incline proved too difficult to get consistent performance from my locomotives.  I have one loco that can go up the helix with a 5 car train, the rest can not.  One poor performing car can prevent most of my locos from going up the turn back loop side with more than 2 cars.  Even with all those obstacles it still makes me smile when my 3yr old wants to go watch the trains :)  I think the design could have worked if I had another 6" of depth to play with, but I do not.

I am also really struggling with how to make the structures make sense on the layout.  I did not do enough pre-planning on where the 'glue' would end up.  I know where the structures go, but I can't make any sort of road system make sense with the space I have.

In the next iteration I will expand the layout to an around the room design which will remove the need for the incline and helix.  It will require a drop leaf or removable section for continuous running though.  I have also done a much more thorough job of finding prototype industries that I want to model before starting.  In the next few posts (or a new thread) I will outline the space the layout can take, as well as the prototype industries that I want to model.

I am attaching a sketch of the the space.  The purple is my desk, and the drop leaf is on the left side.  The shelf depth on the top and bottom can be reallocated but the isle width at the drop leaf is fixed.

There are some fun ideas in the works including an Arduino/stepper vertical staging 'yard' on the right as well as a drop leaf that will hide in a cabinet when dropped.

The first area I am focusing on is the top of the vertical staging yard.  This piece is designed so that the whole section can be lifted to expose multiple 5' long staging tracks.  The section break is where the red lines are.  This section crosses in front of a window and is also right next to my office workstation, so I want to keep the depth to a minimum while still having a scene. 

I am looking at putting the transload shed that was the first structure I built on this section as it's a very small structure and would fit fairly well in the space while still giving a few feet of whitespace on each side.  That fits the prototype shed fairly well.  (streetview)

I have had to mirror the curve and street angle to put the dock door on the isle side while still keeping the section entrance points as close to the wall as I can.  I'll be using this shed:

I've picked up some C40 rail to try hand laying the inside spur/run around on this section.  If all goes well i am planning on using it for all the sidings on the new version.

One concern I have is using the forest as a screen on the front of both ends but not having anything behind the tracks.  I could put in a short backdrop but I am resistant to putting a back drop on this section because it will block more of my office window.  I could extend the depth another inch or to in order to get a few trees behind the tracks but that feels like it would start to be deeper that I really want it to be.  I could also just make the screen really dense & tall in front and hope that it masks the fact that the tracks are right on the rear edge.

The design for the linear slide is coming along nicely.  A piece of 12mm plywood will span between two of these assemblies and the vertical staging will be built on that plywood.  While my design calls for only 3 levels (top and two others) this design could easily be expanded to many more levels with longer linear rails and lead screws.

Sorry to hear about the demise of version 1, as I think the basic design holds a lot of promise for those that want switching and some roundy-round action. But if the functionality isn't there (and it sounds like it isn't), all you can do is move on. Looking forward to whatever you cook up next.
