I look forward to postings here to help learn more on 3d printing as I’ve just added a resin printer to my collection of stuff. Pretty much a blank slate here, nothing anyone can add would be ignored.

I look forward to postings here to help learn more on 3d printing as I’ve just added a resin printer to my collection of stuff. Pretty much a blank slate here, nothing anyone can add would be ignored. I appreciate your interest. I remember years ago talking about how 3D printing wasn't quite to the level to be useful in our modeling efforts, but that day has come and gone! 3D printing, laser cutting, CNC (and this includes Silhouette, Cricut, and other die-cutting machines, and ANY other machine that is driven by computer numeric control), along with ANY and ALL manually operated tools that assist our modeling efforts have, to a degree, revolutionized the hobby of model railroading, and modeling in general. Here's a list of some of my equipment (newest to oldest) include: Flashforge 5M Adventurer FDM 3D Printer Elegoo Saturn 2 Elegoo Mars 3 Sainsmart Genmitsu 3018 PROVer V2 CNC router Sainsmart Genmitsu LC-50 Plus 10W Diode Laser Engraver Comgrow Z1 10W Diode Laser Engraver (likely to be upgraded to 20W or 30W laser module) 1 Generic 3018-PRO CNC router (work area 300mm x 180mm) Comgrow CNC ROBO (a discountinued cnc model) 1 Generic 1610-PRO CNC router (work area 160mm x 100mm) 1 Linksprite 1610 CNC router (discontinued machine with a work area of 160mm x 100mm) Sherline 5400 Vertical Milling Machine Donnell |

Might want to add a Sherline 4000 lathe to the list. I use mine much less than my mills, but there are (round) things where you just GOTTA have it.
For us, I see no reason for a CNC mill or lathe.

Ed I agreed with everything you said up to that last sentence. I think that there is plenty of reason in the form of many custom designed parts and pieces, jigs and fixtures. Regarding the lathe, I do want one as I would like to be able to machine my own wheels and motor flywheels. Donnell |

I agreed with everything you said up to that last sentence. I think that there is plenty of reason in the form of many custom designed parts and pieces, jigs and fixtures. CNC is mostly for repetitive operations, either production of many pieces, or many repetitive operations on one piece. That's not common for our kind of model building. Thinking back, the only thing in model railroading that comes to mind where I might have used CNC is a flat car deck, with a zillion (actually, 124--I just counted them) keyhole shapes all in a special pattern. But it would have taken longer to learn how to do CNC than the time I took to do it by "hand". With my mill, of course. It would have been VERY nasty to have had to do all that with a pin vise and drill bit. Actually, it would have been impossible, because of the keyhole shapes. Jigs and fixtures are one-off, usually with little repetition. I use them a LOT in my model building. Yes, you can do fancy curves, but they don't come up much, if at all. The 7400 manual mill base price is $948. The CNC version of that is $3077. Big jump. It would be far better to put that money into tooling. In my opinion. What I'd rather have is power feed. Cranking that little wheel can put a crick in yer thumb joint. Sherline doesn't sell that, at least for the plain ole 7400. Right now, I'm cutting a strip of Evergreen 1/4" X 3/4" down to track gage, and pretty much all it is is back and forth and drop down for the next layer. Over and over. It's not THAT exciting. And I've got to do it for a strip that's 22" long. I have yet to do any wheels or flywheels. I have wanted to build a fixture for holding steam locomotive driver sets in the lathe, but haven't had the need, yet. I found it's pretty fast turning deep flanges down using a bench grinder and files. My most recent lathe job was a batch of end caps for the supports on some steel ladles. Before that, it was some tubes to position LED's over class light "bulbs". Ed |
