In the recent past, I have offered to large scale modelers resin castings of Aristocraft Replacement Parts. Some of you have contacted me with an order. The support of the members of this forum and my local buddies is much appreciated. To provide a better quality product, I have recently acquired a second 3D printer ( filament type ) to my production equipment. Along with my SLA type machine that makes UHD small parts, I can now make many out of production replacement parts that could not be made by resin casting & silicone mold making. The neat advantage of 3D printing is that the CAD design required to make the new part can be up upgraded to make a better part than the original.
Here is one example, the Pilot Mount for a Pacific locomotive. Certain features on the original are actually off center. Most likely due to machinist’s errors during the injection mold making process. Can’t remember exactly which ones but I found it strange while I was measuring up the part & drawing the CAD file. Secondly, many modelers comment that the Pilot breaks off if the tip is low and hits the track. For this, I reconfigured the area below the mounting screw holes so that there is backing to provide a better rest for the back of the pilot supports.
I’d like to know if there are further improvements that can be done to this part.
Here’s a picture of the new part printed in ABS and painted black.
