I have an axle and bearing that seem to be able to be fitted. I want to try one engine. Its a distraction frankly, but this chassis was worn out. I either set it aside and mill a slot in another chassis or take a shot at getting the ball bearing worked out. Meanwhile I have lots of 3D parts to print which I can do at the same time. So as I am building the kits boxes up, I could try one axle and wheel set. Thinking the drive Axle will be the hardest because the drive gear needs a strong press fit to work. Unless I can figure out a hub and lock nut approach. So its a test lets say that. A few days to verify it can work or not. If not then I need to get new bushing pressed. I have Ball Bearings in the armature assembly, and it lowers the amp draw! So promising! Later, D
I have delivered a 5 engine set of parts for a Customer. With that funding I found a Mini highly accurate Drill Press that is perfect for rough cutting the gear slot in the RIB chassis and Prepping the Chassis for Ball Bearings. I also have found a weakness in my Mini Mill that will require the main housing holding the Dremel to be redesigned with an improved clamping arrangement. I have the concept I need to reduce to CAD mods to the existing adaptor. Plus my X axis Fixed Nut has more backlash than is acceptable. So it need to fix up a new Drive nut which means a complete tear down and reassembly. So all this lost time puts me way back without a backup. That way the Mini Drill Press in on my list of required tools. I will be assembling subassemblies like the smoke, the Puff & Chuff the Ash Pad and Firebox and the tender chassis, trucks and Body which are all required at some point for all 4 of the new kits, so I can shuffle work around to set up time for the mill Rebuild. I just don;t want to see multiple months go by. A week or so I can deal with, And once the Mill is fixed the chassis work will go fast. Not worried, Dennis
I ordered the new drill press. 2 weeks to get it. To be used on the rough cut of the slot, drilling axle holes out for ball bearing, and drilling out blocks of aluminum for new engine chassis. The mini CNC Mill will be used for final cuts and finishing cuts. This will speed up chassis prep and provide a better end product with a future.
