Take a look at the DynamicCogWheelRenderer.java#L81. If I understand the code correctly, that should be how the wheel render itself using the texture of a _log or _stem. The ID is modID:stripped_<type>_log

TerraFirmaCraft's ID for woods IIRC is tfc:wood/oak_log or tfc:wood/log/oak (I'll check and update)

Let me know if you want me to make PR

Yep, this is re-used from how create generates textures for water wheels. Seems like they've added compatibility for TFC like so. We could probably use a very similar implementation. I'd be happy to add this myself when I've got some time but you're welcome to open a PR if you'd prefer :)

Im not sure when I'll next be able to get round to working on this, might be about a little bit so if you've got the time and dont mind a PR would be great. I'll and get the changes released asap

Alright, I should be able to create PR tomorrow.
