Thread: First ever real build lews featherweight

Oh i forgot over the last few weeks i made a little progress on the wheels!

team SC batten boxes on some 65 shore 125mm castors that i have modified in my lill manual mill, i milled the faces flat and milled out the roller bearings this took a little getting right as i wanted to save as much meat as possible!

The hubs are held on the 12mm shaft portion with a keyway then the nut and finally the left hand thread screw with a nice anodised countersunk washer keeps the nut double snug!

In the last picture below you can see (not very clearly a ring between the hub and the wheel rim) i 3d printed a tight press fit ring that matches the hub and the wheel fillet this keeps my hub concentric while i drilled the mounts, im actually going to keep these fitted with epoxy and make them in a lairy colour or glow in the dark filiment!

Ok so ive had some more good progress last night, ive popped out a few more mdf dummys on the cnc. its been usefull i can see i need to make pockets on the inner weapon plate im just awaiting a 5050 motor to test fit the pocket for the motor.

its given me a feel for the space avalible for the rest of the electronics i can now hopefully trim some dimensions down and save a little weight.
i still need to find a way to get the mill to chamfer the front frame on the ally version, if not ill prob do that on my manual mill.

Not sure why its upside down the source was correct way up ??
