Hi Scott, interesting project. I would simply rework the chassis cover plate to accommodate the trailing wheelset. But what's about power pick up?
Steffen, Thanks. I am thinking of cutting the pickup and desoldering at an angle to pick up the trailing wheel. Scott
My one-eyed Italian buddy's[ kid came through for me again! He resin printed these using an N scale STL file by AJKOCHEVAR over on Cults, reduced to Z.[/ATTACH]
Absolutely stunning. And running my own 3-D printer I know how hard it is to hold those micro-thin tolerances, but it is possible. Although as JOHN has stated, this small stuff is very delicate. Consider the fact a derailment would take it out. But that’s the chance we take when we live on Z-edge! On a sidenote, my own 3D PRINTING ventures have been put on hold temporarily due to a potential “resin rash” issue I have been dealing with. It started back in December after I got a bit of resin on my left hand. Although it was quickly wiped off, the question of concern was did it already do some damage. The rumor in the industry is once you get a resin rash, you never really are able to shake it, and some people have given up 3D PRINTING because of it. I visited a dermatologist on Monday and she waved off any prospects of it being related to 3-D printing resin. It’s more of an eczema issue due to dry skin in this area with winter being what it is. So fingers crossed, in about another 2 to 3 weeks I will return to printing and see if the rash manifests itself again. If not, I’m back in business. And I’ve got some cool things I’ve been working on too.
Interesting. There are folks in the model rocket community that have developed a sensitivity to something in two-part epoxy. It is said that once developed, it never goes away. Not everyone gets it, but the only treatment is prevention, so the guys that get it advocate for *always* wearing (latex, etc.) gloves when using epoxy. I wonder if some of the chemicals involved are similar.
This is the same chemical basis and concern. In fact, its a greater concern in the flooring industry that use an epoxy for laying down ceramic tile. Although I am always gloved up, I grabbed a build plate that I thought was fully clean of any resin, but has a hidden cavity that held some residual resin. Most comments I have seen is that everyone eventually gets a "small" amount of exposure, but some are sensative and some not. Now, there is also the airborne exposure as well, which even masking up does not prevent 100% safety. I have a VOC meter I use, and it never goes off until I pop the top on the rinse and cure station which utilizes isopropyl alchohol. I am suspicious of the resin becoming airborne via that process. There are many different air-capture systems and I use one for my printer, but not my rinse and cure station --- but that is now on the radar. Lastly, with the dry freezing air here in South Dakota, various skin rash maladies are not uncommon. So I am hoping this is simply a seasonal issue and I am not one of the unlucky ones that is experiencing this due to the resin. Time will tell.
In the 70’s, my father brought home commercial 2-part epoxy in baby food jars for fix-it’s. The accelerator would push your head back against the wall . . Quickly. Due to nasal moisture, you would smell it for hours! Ah, the 60’s ( s s s n n n i i f f f f)
Since I gave away my Timesaver module, I don't have an old barn anymore, so I am working on a new, old barn with a bad roof: I am doing my standard magnetic base with pogo pin bridge rectifier electrical too. These bridge rectifiers are tiny and cheap insurance against someone connecting 16VAC instead of 12VDC as accessory power: Pogo (spring loaded) pins centered between a couple super magnets insure the structure snaps in proper alignment to the contact strip base, and always get good electrical contact.
Looks great as always Robert. I still got one of your originals from back in day. I pulled it when I built an extension and it will be used again never can have too many barns!
That is a sweet looking barn! I really like how the built in OLD came out with cracked boards and knot holes. Did you make the roof leaking too?
So I'm making the roof hella leaky on this one! So I am trying to make the lighting and wiring smaller and as stealth as I can, so I am using copper tape and SMT for the lighting: Then I painted it over with brown paint to minimize it before gluing the roof pieces on: And you can see the lights inside the paddock side of the barn. This is because if I put a horse or cow or something inside, I want people to see it. Notice the magnet is sticking to a 9V battery and powering the barn: To hide all the main barn electronics I just placed some blocks to represent hay bales, then I painted them with tan Apple Barrel, and sprinkled some Woodland Scenics fine yellow turf to represent hay. It hides all the electronics well enough and leaves space for a tractor down below, and maybe a guy up top or some other details. At least being lit, you will be able to see what's going on: And here is the first roof panel with the leaky roof. I want it really spanky looking! :
