I’ve been working on my first electric skateboard and so far stuff has gone great (Except for the long wait on various parts from HK and my VESC). Now I bumped into a bit of an issue:
I bought the Enertion pulley system, modifying my truck for the wheel pulley went fine, but now I noticed the Turnigy SK3 (245kv) motor doesn’t have the slot/keyway in the shaft see video.
So currently I have no way of ensuring the pulley doesn’t slip. I might want to cut the keyway myself but I have no Dremel handy so that’ll be quite the challenge.
@Jamy I made a keyway with a dremel tool in an sk3 245KV and I would not recommend doing that! It’s very difficult to cut the shape just right. I don’t know if I’ll ever get that key out of the shaft! Do a flat spot with a grub screw. If you don’t want to tap your motor pulley, I’d suggest buying a different pulley. At this point what’s another $15?
DIYES has a motor mount that works w Paris trucks. I use one and it’s awesome. I haven’t gone pulley shopping in a while. Every vendor sells some version of motor pulley, but it gets harder to find as you get more specific about what you need. Check the usual suspects.
