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.
